How Mortgage Amortization Affects the Total Cost of Your Home Loan

Mathew Pezon • July 20, 2026

Seeing how your mortgage is structured can mean the difference between paying tens of thousands of dollars more than necessary and making smart, confident decisions about your loan. Using a mortgage amortization calculator early in the process gives you a clear picture of exactly how much your home will cost over time, not just what your monthly payment looks like on the surface.

Most homeowners focus on the monthly payment when shopping for a loan. That number matters, but it only tells part of the story. The real cost of your mortgage is determined by an amortization schedule, which maps out every payment you will make from the first month to the last. Each payment is split between principal, which reduces what you owe, and interest, which is the fee you pay the lender for borrowing the money. In the early years of a loan, the split is heavily weighted toward interest. That means you are paying the bank a lot before you are really paying down your home.

How Much Interest Will You Pay Over the Life of Your Mortgage?

The total interest paid on a mortgage can be shocking when you see it laid out clearly. A mortgage amortization calculator makes that number visible so you are not caught off guard.

The Front-Heavy Nature of Amortization

On a 30-year mortgage at a 7% interest rate for a $250,000 loan, your monthly payment would be roughly $1,663. Over 30 years, you would pay approximately $598,680. That means you paid around $348,680 in interest alone on a $250,000 home. The home did not cost $250,000. It costs close to $600,000 when you include the full cost of borrowing.

This happens because of how amortization works. In the first month of that same loan, about $1,458 of your payment goes toward interest, and only around $205 goes toward reducing what you owe. By month 12, the split has barely moved. You are still paying the bank far more than you are paying down the debt.

Why Early Payments Feel Like They Go Nowhere

This front-heavy structure is intentional. Lenders calculate interest on your remaining balance each month. Since that balance is highest at the start of the loan, interest charges are highest then, too. As the years go by and the balance slowly drops, more of each payment shifts toward principal.

The practical effect is that it can take more than 20 years of a 30-year loan before you are paying more principal than interest each month. That is a long time to feel like you are barely making a dent.

Using a Calculator to See Your Own Numbers

Plugging your loan details into a mortgage amortization calculator changes how you see your debt. You can input your loan amount, interest rate, and term to get a month-by-month breakdown of every payment. Seeing the full amortization schedule helps you understand not just what you owe today, but what you are committing to over the life of the loan. For Bethlehem Township homeowners considering a home purchase or refinance, that transparency is powerful.

Does a Shorter Loan Term Really Save You Money?

Switching from a 30-year mortgage to a 15-year mortgage is one of the most effective ways to reduce your total interest paid. The savings are significant, but the tradeoff deserves a close look.

The 15-Year vs. 30-Year Comparison

Using the same $250,000 loan at 7% interest, a 15-year mortgage would carry a monthly payment of roughly $2,247. That is about $584 more per month than the 30-year option. However, the total cost of the loan drops dramatically. Over 15 years, you would pay approximately $404,460 in total, meaning your total interest paid would be around $154,460.

Compared to the 30-year version, where interest reaches nearly $348,680, choosing the shorter term saves roughly $194,000 in interest. That is not a minor difference. It is the kind of loan cost comparison that entirely changes how people think about their mortgage.

When the Higher Payment Makes Sense

A 15-year mortgage is not the right fit for every household. The higher monthly payment requires more income stability and leaves less room for unexpected expenses. If your budget is tight, committing to that larger payment can create financial stress that outweighs the long-term savings.

Some homeowners find a middle path. They take a 30-year loan for the lower required payment but make extra principal payments when they can. This shortens the loan term and reduces interest costs without locking them into a higher monthly obligation.

Running the Numbers Before You Commit

A mortgage amortization calculator lets you test both scenarios side by side. You can see exactly how many years you will shave off the loan and how much interest you will save by increasing your payment even slightly. Before committing to any loan structure, it is worth running these numbers using your actual income and expenses.


How Does Your Interest Rate Change Your Total Loan Cost?

Your interest rate is one of the most powerful factors in determining what your home actually costs you. Even a half-point difference can add or remove tens of thousands of dollars from your total loan cost over time.

Small Rate Changes, Large Long-Term Impact

Take that same $250,000 loan on a 30-year term. At 6.5% interest, the monthly payment drops to roughly $1,580, and total interest paid over the life of the loan comes to about $318,868. At 7%, the payment rises to $1,663 and total interest climbs to around $348,680. That half-point increase in rate costs you nearly $30,000 more over 30 years.

Now stretch that comparison to a full percentage point. At 6%, your total interest paid would be approximately $289,595. Compared to 7%, the difference is nearly $59,000. That is the kind of money that changes retirement plans, college funding, and long-term financial security.

Why Rate Shopping Matters More Than People Think

Many borrowers focus on finding the right home and treat the mortgage rate as something they cannot control. In reality, even modest differences between lenders can have a huge impact on your total loan cost. Getting quotes from multiple lenders and negotiating your rate are among the most valuable steps in the home-buying process.

Your credit score, debt-to-income ratio, and down payment size all affect the rate you are offered. Improving any of these before applying can lower your rate and reduce how much you pay over the full mortgage term.

Comparing Rates With an Amortization Schedule

Running different interest rate scenarios through a mortgage amortization calculator gives you a side-by-side view of how rate changes affect your amortization schedule. You can see how each rate affects your monthly payment, your payoff timeline, and your total interest paid. For homeowners in Camp Hill who are weighing their financing options, this kind of detailed comparison is one of the most useful tools available.

Sometimes the numbers make it clear that the current market conditions are not the right time to buy or that waiting to improve your credit score first could save a significant amount over the life of the loan.


Frequently Asked Questions

What does a mortgage amortization calculator actually show you?

A mortgage amortization calculator shows you a full payment-by-payment breakdown of your loan, including how much of each payment goes toward interest versus principal. It also shows you the total amount you will pay over the life of the loan, including all interest charges.

How much more does a 30-year mortgage cost compared to a 15-year mortgage?

On a $250,000 loan at 7% interest, a 30-year mortgage costs roughly $194,000 more in total interest than a 15-year mortgage. The monthly payment on the longer loan is lower, but the extended mortgage term length means interest accumulates for twice as many years.

Can making extra payments reduce the amount of interest I pay?

Making even small extra principal payments each month can shorten your loan term and reduce your total interest paid by thousands of dollars. Plugging different extra payment amounts into a mortgage amortization calculator shows you exactly how much you can save and how many years you can cut from your payoff timeline.

FHA 3.5 Percent Down Payment: What It Is and How It Works

By Mathew Pezon • July 21, 2026
The FHA 3.5 percent down payment makes homeownership possible for millions of buyers who cannot afford a large upfront sum. Backed by the Federal Housing Administration, this program was designed to lower the barrier to entry for people who have a steady income but limited savings. Learning how it works, who qualifies, and what it costs can help you make a smarter decision before you ever sign a purchase agreement. What Is the FHA 3.5 Percent Down Payment Rule? The FHA down payment rule sets the minimum amount a buyer must put down when using a government-backed FHA loan. Rather than the traditional 20 percent required by many conventional lenders, the Federal Housing Administration allows qualified buyers to put down as little as 3.5 percent of the purchase price. On a $250,000 home, that is $8,750 instead of $50,000. That difference changes everything for buyers who are saving money while also paying rent. Where the 3.5 Percent Rule Comes From Congress created the Federal Housing Administration in 1934 during the Great Depression to stabilize the housing market. The agency insures FHA loans, meaning if a borrower defaults, the lender is protected. That government backing is what allows lenders to accept a lower down payment without taking on excessive risk. The 3.5 percent floor has remained a defining feature of the program for decades. It is not a promotional rate or a temporary offer. It is built into federal housing policy and applies to FHA-approved lenders nationwide, including those serving buyers in Palmer Township , PA. How the Down Payment Amount Is Calculated The minimum down payment is based on the lesser of the purchase price or the appraised value. If a home is listed at $200,000 but appraised at $190,000, the FHA uses $190,000 as the base. Three and a half percent of that would be $6,650. This matters because buyers sometimes offer more than the appraised value in competitive markets. The FHA will not adjust its down payment calculation upward to match an inflated offer. That gap becomes the buyer's responsibility outside the loan. Mortgage Insurance Is Part of the Deal One trade-off with any low-down-payment mortgage is the cost of mortgage insurance. FHA loans require two types of premiums: an upfront mortgage insurance premium paid at closing and an annual premium spread across monthly payments. The upfront premium is currently 1.75 percent of the loan amount. The annual premium varies based on loan term, loan amount, and down payment size. These costs protect the lender, not the buyer, so it is worth factoring them into your overall budget.

The Role of Inflation in Pushing Mortgage Rates Higher

By Mathew Pezon • July 17, 2026
Why are mortgage rates going up faster than most homeowners expected? Inflation is one of the biggest forces driving this shift, and seeing the connection between rising prices and higher borrowing costs can help you make smarter decisions about your home. Why Does Inflation Make Mortgage Rates Go Up? Inflation and mortgage rates move together more closely than most people realize. When the cost of everyday goods rises, lenders respond by raising the cost of borrowing. The two are deeply connected, and ignoring that relationship can leave homeowners caught off guard. How Lenders Protect Themselves Against Rising Prices Lenders make money by collecting interest over time. When inflation is high, every dollar repaid in the future is worth less than it is today. To protect their profits, lenders raise interest rates so that the money they earn keeps up with the declining value of the dollar. Think of it this way: if a lender gives you $300,000 today and inflation runs at 6% per year, the money they collect back over 30 years is worth far less in real terms. Higher mortgage rates are their way of offsetting that loss of purchasing power. The Federal Reserve's Role in the Cycle The Federal Reserve, often called the Fed, does not directly set mortgage rates. But it does set the federal funds rate, which is the interest rate banks charge each other for overnight loans. When inflation runs high, the Fed raises this rate to cool down spending across the economy. As borrowing becomes more expensive for banks, those costs flow downstream to consumers. That means auto loans, credit cards, and home loans all get pricier. Mortgage lenders also closely watch the yield on 10-year Treasury bonds. When Treasury yields rise alongside Fed rate hikes, mortgage rates follow. The Consumer Price Index and What It Signals The consumer price index, or CPI, measures how much everyday goods and services cost compared to a previous period. It tracks categories like housing, food, transportation, and medical care. When the CPI rises sharply, it tells the market that inflation is accelerating. Mortgage investors, especially those who buy mortgage-backed securities, pay close attention to CPI reports. A hot CPI reading often triggers an immediate spike in mortgage rates because investors demand higher returns to offset expected inflation. This is one reason mortgage rates can jump within days of a government data release.

What Is a Fair Cash Offer for Your Home and How Does It Work?

By Mathew Pezon • July 16, 2026
Selling your home is one of the biggest financial decisions you will ever make, and understanding your options can save you thousands of dollars. A fair cash offer for home sellers in Pennsylvania means getting a real, no-obligation offer based on your property's actual value, without the delays and fees that come with traditional real estate sales. What Does a Fair Cash Offer for a Home Actually Mean? A fair cash offer is not a lowball number pulled out of thin air. It is a carefully calculated figure that reflects your home's current market value, its condition, and the prices at which comparable homes in your area have recently sold. The goal is to give you a number that makes sense for both sides. Cash Offers vs. Traditional Listing Prices When you list a home on the open market, you often see a higher asking price on paper. But that number rarely tells the whole story. After realtor commissions, closing costs, inspection repairs, and months of carrying costs like mortgage payments and utilities, your actual take-home amount can drop significantly. A cash offer skips most of those deductions. There are no agents taking a 5- to 6-percent commission, no lender-required repairs, and no waiting for buyer financing to be approved. What you are offered is much closer to what you actually walk away with. Why "Fair" Matters More Than "High" The word fair is important here. A genuinely fair offer accounts for the real costs involved in buying, holding, and reselling a property. It is not inflated to win your attention, nor so low that it takes advantage of your situation. For homeowners in Pen Argyl dealing with job loss, divorce, inherited property, or looming foreclosure, a fair offer means being treated with respect. It means receiving a transparent number backed by real data, not pressure tactics. The Role of As-Is Condition in Cash Offers One of the biggest advantages of a cash home sale is that your property is evaluated as-is. You do not need to repaint rooms, replace a worn roof, or update an outdated kitchen before selling. The offer already accounts for the home's condition, so you can move forward without spending another dollar on the property. This is especially helpful for homeowners dealing with aging homes, deferred maintenance, or properties that would struggle to pass a traditional buyer's inspection.

Homes For Sale By Price Range in Allentown: A Complete Buyer's Guide

By Mathew Pezon • July 15, 2026
Searching for homes for sale by price range in Allentown, PA, can feel overwhelming if you do not know where to start. The Allentown housing market has changed a lot over the past few years. Prices have climbed, inventory has tightened, and buyers who walk in without a clear budget often lose out to more prepared offers. Knowing your number before you search is not just helpful; it's essential. It is essential. What Price Ranges Are Available for Homes For Sale in Allentown, PA? Understanding the full spectrum of property listings in Allentown gives you a realistic picture before you fall in love with something out of reach. Here is how the market generally breaks down. Entry-Level Homes: Under $200,000 This price tier exists in Allentown, but it is shrinking fast. Homes under $200,000 are typically older row houses or small single-family properties, often in the western or northern parts of the city. Many need work. Some need significant repairs. If you are shopping in this range, your buyer budget needs to account for renovation costs in addition to the purchase price. A home listed at $150,000 could easily need another $30,000 to $50,000 in repairs to be move-in ready. Go in with open eyes and a trusted contractor. Mid-Range Homes: $200,000 to $500,000 This is where most of the action is in Allentown. The $200,000 to $500,000 range covers a wide variety of properties, from updated row homes and Cape Cods to modest single-family houses with yards. At the lower end of this range, expect smaller square footage or properties that need cosmetic updates. At the higher end, you will find move-in-ready homes in more desirable pockets of the city. Competition in this band is strong, and good homes move fast. Upper-Range Homes: $500,000 and Above Allentown's upper tier is expanding as the Lehigh Valley real estate market has appreciated overall. Homes above $500,000 in the city often offer more space, updated kitchens and baths, and quieter residential streets. Above $550,000, you start crossing into the suburbs and neighboring communities like Wescosville, South Whitehall Township, and Upper Macungie. If your budget reaches this level, you have the flexibility to compare Allentown proper against surrounding townships.

Does Renovating Your Home Increase Your Home Value Estimator Result?

By Mathew Pezon • July 14, 2026
Which Home Improvements Show Up in a Home Value Estimator? A home value estimator is an online tool that uses recent sales data, square footage, location, and condition to generate a price range for your property. Tools like Zillow's Zestimate or Redfin's estimate pull from public records and listing data. They're fast and free, but they have real limits. Most automated tools can't walk through your front door. They don't see your new countertops or your freshly painted walls. What they do respond to is changes in recorded data, such as a permitted addition that increases your square footage or a basement finish logged in public records. What Data These Tools Actually Use Automated estimators look at a handful of measurable factors. These typically include: Square footage reported in public records Number of bedrooms and bathrooms Lot size and location Recent comparable home sales in your area Year built and any permitted additions If your renovation doesn't change any of these recorded data points, the tool may not reflect your work at all. Permitted vs. Unpermitted Renovations This is where many homeowners get caught off guard. If you add a bathroom or finish your basement and pull the proper permits, that work often gets updated in county records. A home value estimator may then pick up the change the next time it syncs data. Unpermitted work, no matter how beautiful, rarely shows up in these tools. It also creates headaches during appraisals and buyer inspections. Permitted improvements give you the best shot at seeing your renovations reflected in an estimated value. Cosmetic Upgrades vs. Structural Changes Painting your living room or replacing cabinet hardware looks great in photos. But cosmetic upgrades rarely change what an automated estimator reports. They don't change your square footage, bedroom count, or any other data field the algorithm uses. Structural changes, like adding a bedroom, converting a garage, or building an addition, are the moves that tend to register. If your goal is to raise your estimated value before listing, focus on improvements that change your home's recorded specs.

What Is a Good Mortgage Rate and How Do You Know If You Found One?

By Mathew Pezon • July 13, 2026
If you are trying to figure out where to find the best mortgage rates, you are asking exactly the right question. Understanding what a competitive rate looks like and how to tell if a lender is giving you a fair deal can save you tens of thousands of dollars over the life of your loan. We work with homeowners across Hershey every day, and a common question we hear is: "Is the rate I was quoted actually good?" The answer depends on several factors, and this article will walk you through all of them clearly. What Does a Good Mortgage Rate Actually Look Like Right Now? Mortgage rates change constantly. What counted as a great rate five years ago may look very different from what is available today. Before you can judge a rate, you need to understand the landscape. The Role of the Federal Funds Rate The Federal Reserve does not set mortgage rates directly, but its decisions heavily influence them. When the Fed raises its benchmark rate, lenders typically raise mortgage rates too. When the Fed cuts rates, home financing costs often come down with them. This means the definition of a "good" mortgage rate shifts with the economic environment. In a high-rate environment, a rate that feels expensive may still be competitive. Context matters more than the number itself. What Benchmarks Should You Use? A mortgage rate benchmark gives you a starting point for comparison. Freddie Mac publishes a weekly survey of average 30-year and 15-year fixed mortgage rates across the country. This is one of the most widely used references for buyers and lenders alike. Here are a few things to keep in mind when using benchmarks: National averages reflect a mix of borrower profiles. Your rate will vary based on your credit score, down payment, and loan type. A rate within 0.25% of the national average for your loan type is generally considered competitive. A rate more than 0.5% above the average deserves a closer look before you commit. How Credit Score Affects What Is "Good" for You Not every borrower gets the same rate. Lenders price loans based on risk, and your credit score is one of the biggest factors they consider. A borrower with a 760 credit score will almost always receive a lower rate than someone with a 640 credit score. So when you hear that the average 30-year fixed rate is a certain number, understand that number assumes a strong credit profile. If your score is lower, your personal benchmark shifts accordingly.

How Much House Can I Afford? Using a Mortgage Calculator to Set Your Budget

By Mathew Pezon • July 10, 2026
Figuring out how much home you can comfortably afford is one of the most important steps you can take before starting your home search. A mortgage calculator gives you a fast, practical way to work backward from your monthly income and expenses to find a home price that actually fits your life. Most people use these tools after they fall in love with a house. The smarter move is to use one before you ever set foot inside an open house. How Do You Use a Mortgage Calculator to Find Out What You Can Afford? A mortgage calculator is not just for checking what your payment would be on a specific house. Used in reverse, it becomes a powerful home affordability tool that helps you set a realistic ceiling before you start shopping. Here is how to approach it the right way. Start With Your Monthly Take-Home Income Before you touch any calculator, you need one number: your actual monthly income after taxes. This is not your salary on paper. It is the money that lands in your bank account each month. If you are salaried, this is straightforward. If you are self-employed or have variable income, use an average of the last 12 to 24 months. Lenders will do the same thing, so you might as well start there. Once you have that number, multiply it by 0.28. That gives you your maximum suggested monthly housing payment, which includes your mortgage principal, interest, taxes, and insurance. We will explain why 0.28 matters in the next section. Plug the Numbers Into the Calculator Now open a mortgage calculator and enter the payment you just calculated as your target monthly amount. Then adjust for: Interest rate: Use a realistic current rate, not a best-case scenario. Check what lenders are offering right now for a 30-year fixed loan. Loan term: Most buyers choose a 30-year term, but a 15-year term means higher payments and lower total interest. Down payment: Enter what you can actually put down today, not what you hope to save later. The calculator will show you an estimated loan amount. Add your down payment to that number, and you have your target home price. That is your budget ceiling. Adjust Until the Numbers Feel Comfortable A tool gives you a number, but comfort is something only you can judge. Run the calculator a few times with slightly different rates and down payment amounts. See how the monthly payment shifts. If a $1,400 payment feels manageable but $1,700 keeps you up at night, that difference matters. Build a housing budget around what is genuinely sustainable, not the absolute maximum a lender might approve you for. Lenders approve based on risk. You need to plan based on your actual life.

Mortgage Rate Calculator: How to Use One to Estimate Your Monthly Payment

By Mathew Pezon • July 9, 2026
If you are trying to figure out what you can afford before buying or selling a home, a mortgage rate calculator is one of the most useful tools you can use. Understanding your monthly payment estimate gives you real power. Whether you are weighing a new purchase or thinking about what your current home is worth in today's market, knowing how to read these numbers puts you in a much stronger position. What Is a Mortgage Rate Calculator and How Does It Work? A mortgage rate calculator is a simple online tool that estimates your monthly mortgage payment based on a few key inputs. You enter your loan details, and the calculator does the math for you in seconds. Most of these tools are free and easy to find. Banks, real estate websites, and financial services sites all offer versions of this calculator. The outputs may look slightly different from one site to another, but they all work using the same basic formula. The Math Behind the Calculator The formula used is called an amortization formula. It sounds technical, but the idea is straightforward. It calculates how much you owe each month based on your loan amount, interest rate, and the number of months you have to repay the loan. Each monthly payment covers two things: a portion of the money you originally borrowed (called the principal) and a portion of the interest your lender charges. In the early years of a loan, most of your payment goes toward interest. Over time, more of it goes toward paying down the principal. Fixed Rate vs. Adjustable Rate Most home loan calculators let you choose between a fixed interest rate and an adjustable rate. A fixed interest rate stays the same for the entire loan term, so your monthly payment never changes. An adjustable rate starts lower but can rise or fall over time based on market conditions. For most homeowners who want predictable payments, fixed rates are the more comfortable option. If you are in Fountain Hill and comparing different loan types, running both through the calculator can help you see the difference clearly. What the Results Tell You Once you enter your numbers, the calculator shows your estimated monthly payment. Some tools also show a full amortization schedule, which is a month-by-month breakdown of how your payments are split between principal and interest over the life of the loan. This is helpful because it shows you the total cost of the loan, not just the monthly payment. A loan with a lower monthly payment but a longer term often costs significantly more in interest over time.

What Is the Average Closing Costs Percentage for Home Buyers?

By Mathew Pezon • July 8, 2026
If you are buying a home and wondering how much extra cash you need to bring to the table, the average closing costs percentage is one of the most important numbers to understand. In this article, we break down what that percentage means, which fees make it up, and how different loan types can change what you owe at closing. Most buyers focus on the purchase price and the down payment. Closing costs often catch people off guard. Knowing what to expect before you sit down at the closing table can save you from serious financial stress on one of the biggest days of your life. What Does Average Closing Costs Percentage Mean for Home Buyers? The average closing cost percentage is the total amount of transaction costs a buyer pays at closing, expressed as a percentage of the home's purchase price. In the United States, buyers typically pay between 2% and 5% of the purchase price in closing costs. On a $300,000 home, that means anywhere from $6,000 to $15,000 in additional fees due at closing. That range might sound wide, but the exact number depends on your loan type, your lender, and the state where you are buying. Here in Hazleton , local fees and taxes can push that number toward the higher end of the range, so it pays to plan.

Best Time to Buy a House Based on Interest Rates: What Every Buyer Should Know

By Mathew Pezon • July 7, 2026
Figuring out the best time to buy a house, considering interest rates, makes sense, and is one of the most important decisions you will face as a buyer. Get the timing right, and you could save tens of thousands of dollars over the life of your loan. Get it wrong, and a small rate change can cost you hundreds of dollars every single month. We work with homeowners across Allentown, PA, every day, and we hear this question constantly: "Should I wait for rates to drop, or buy now?" The honest answer depends on understanding how rates actually move and what they mean for your wallet. How Do Mortgage Interest Rates Affect the Best Time to Buy a House? Interest rates are not just a number on a bank website. They directly control how much house you can actually afford and what your monthly mortgage payment will look like for the next 15 to 30 years. The Direct Connection Between Rates and Monthly Payments Here is a simple way to see the impact. On a $300,000 home with a 30-year loan: At a 6% interest rate, your monthly payment is roughly $1,799. At a 7% interest rate, your monthly payment jumps to roughly $1,996. At an 8% interest rate, your monthly payment climbs to roughly $2,201. That is a difference of nearly $400 per month from a two-point rate swing alone. Over 30 years, that adds up to more than $140,000 in extra payments. This is exactly why timing your purchase around rate movements matters so much. How a Fixed Rate Mortgage Locks In Your Costs When you choose a fixed-rate mortgage, your interest rate stays the same for the entire life of the loan. That means if you lock in a low rate today, you are protected even if rates rise next year. Many buyers overlook this advantage. Locking in during a favorable period gives you cost certainty that no amount of future market watching can provide. Adjustable-rate mortgages work differently. They start with a lower rate but can increase after a set period. For most buyers planning to stay in a home long-term, a fixed rate is the safer choice because it removes the guesswork entirely. What "Home Affordability" Really Means Home affordability is the combination of home prices and interest rates. A home that costs $350,000 at a 5% rate may be more affordable than a $300,000 home at an 8% rate. Lower prices do not automatically mean better affordability if rates are high. This is a mistake many first-time buyers make. They wait for prices to drop without realizing that rising rates can cancel out any savings from a lower purchase price.
