The impact of interest rates on home prices and affordability

Interest rates move home prices indirectly, by changing what buyers can afford to bid, and they hit your budget far harder than the price tag. On a $300,000 30-year fixed loan, one percentage point of rate changes the principal-and-interest payment by roughly $200 a month, while national prices grind along at low single digits: the Federal Housing Finance Agency (FHFA) House Price Index rose 2.1% year over year in the second quarter of 2026, per its August 25, 2026 release.
Higher rates cool demand, but they don’t force existing owners to sell. That asymmetry is why a rate spike usually produces flat-to-slow price growth with far fewer sales, not a crash. Here’s how the impact of interest rates on home prices works, what one point of rate does to your payment, and how to think about buying now versus waiting.
Key takeaways:
- Rates change demand, not supply: FHFA research found each percentage point that market rates sit above a homeowner’s own rate cuts the odds of that home selling by 18.1%, so higher rates freeze listings while shrinking what buyers can bid.
- One point of rate outweighs a year of price movement: On a $300,000 loan, one point moves the payment about $200 a month and roughly $71,000 over 30 years; a 3% price change moves it under $60.
- Falling rates rarely arrive as a discount: a lower rate hands every competing buyer roughly 10% more purchasing power the same moment it reaches you, which historically shows up as firmer prices rather than cheaper houses.
How do interest rates affect home prices?
Through the payment, not the price. A buyer with a fixed monthly budget can carry roughly 10% less loan for every percentage point rates rise, so as rates climb, the pool of buyers who can bid at any price shrinks, offers come in lower, homes sit longer, and price growth decelerates.
Notice what that chain does not include: it doesn’t reduce the number of houses that exist. Rates work almost entirely on demand, while supply responds slowly, through building decisions made years earlier and owners choosing whether to list. That mismatch is why the rate-price relationship is real but muted.
Timing matters too. Rates move in days; prices move in quarters. When prices “aren’t responding” to a rate move, you’re usually reading a lag. Our Mortgage Rates & Market guide covers what sets your quote, our Housing Market Trends hub tracks how those shifts surface in sales data, and our breakdown of the impact of inflation on home prices covers the force running underneath both.
Why doesn’t a Fed rate cut lower your mortgage rate?
Because the FOMC sets an overnight interbank rate while your 30-year loan is priced off the 10-year Treasury yield plus a mortgage-bond spread that has averaged about 1.76 percentage points since Freddie Mac’s survey began in April 1971 and moves on its own, our guide to the Federal Reserve and mortgage rates walks that transmission chain step by step, and mortgage rate volatility explains why daily swings matter more to your lock than the policy rate does.
Because rates change weekly, this article deliberately doesn’t print one. For the current national average, check the Freddie Mac weekly mortgage rate survey, published Thursdays at noon Eastern from thousands of conventional, conforming purchase applications. Your quote will land above or below it.
How much does a 1-point rate change actually cost you?
About $200 a month on a $300,000 loan, roughly $71,000 in added interest over 30 years, and about 10% of the loan you can carry at the same payment. Here’s the arithmetic at three illustrative rate levels.1
| What a 1-point rate change does to a $300,000 loan | At 6% | At 7% | At 8% |
|---|---|---|---|
| Monthly principal and interest | $1,799 | $1,996 | $2,201 |
| Added monthly cost per 1-point step | , | +$197 | +$205 |
| Total interest over 30 years | $347,515 | $418,527 | $492,466 |
| Loan you could carry on a $1,799 payment | $300,000 | $270,351 | $245,127 |
| Purchasing power vs. the 6% row | , | −9.9% | −18.3% |
Now set that beside a price change on the same house. Take a $375,000 purchase with 20% down (a $300,000 loan) at 6.5%, for a payment near $1,896. Cut the price 3% and the payment drops about $57 a month. Cut the rate one point instead and it drops about $193, more than three times as much. Our look at affordability challenges in today’s housing market works the income side of the equation.
One caution before comparing quotes: the note rate isn’t the full cost of the loan. Under Regulation Z, the annual percentage rate folds in prepaid finance charges. The CFPB describes the APR as reflecting “the interest rate, any points, mortgage broker fees, and other charges that you pay to get the loan.” It isn’t simply “rate plus fees,” and on an adjustable-rate loan it rests on assumptions that may not hold. Read the CFPB explanation of interest rate versus APR before deciding which offer is cheaper.
Why don’t home prices fall as fast as affordability?
Because rising rates lock existing owners in place, and a seller who never lists is a home that never reaches the market. FHFA put numbers on it: for every percentage point that market rates exceed a borrower’s own origination rate, the probability of that home selling drops 18.1%.
The aggregate effect is large. FHFA Working Paper 24-03, The Lock-In Effect of Rising Mortgage Rates (Batzer, Coste, Doerner and Seiler, published March 18, 2024), estimated that lock-in prevented roughly 1.33 million sales between the second quarter of 2022 and the fourth quarter of 2023, cutting sales among fixed-rate mortgage holders 57% in that final quarter. The resulting shortage pushed values up about 5.7% while the direct drag of higher rates pushed them down about 3.3%, net upward pressure on prices as affordability collapsed.
That inverts the intuition most buyers arrive with: higher rates did suppress prices, but the supply they froze pushed prices up by more. Two brakes work the same direction. Most owners aren’t forced sellers, so they delist rather than discount, and homebuilding can’t flex fast enough to replace missing listings.
The visible casualty isn’t price, it’s transaction volume. Existing-home sales ran at a 4.06 million seasonally adjusted annual pace in July 2026, down 1.7% from June, while the median existing-home price still rose 2.0% year over year to $434,100 and unsold inventory held at a 4.6-month supply, per NAR’s August 11, 2026 release. Fewer sales, higher median: the signature of a rate-constrained market.
Why do home price reports disagree with each other?
Because each counts different homes, transactions and periods on August 25, 2026 the FHFA index reported national prices up 2.1% year over year for 2026 Q2 while S&P Dow Jones Indices reported the Cotality Case-Shiller National Index up 1.5% for June, and that same FHFA release put the East North Central division first among all nine census divisions at 4.5% against a Pacific division slightly above 0.0%. Our guide to housing market reports sets out what each measure covers and what it misses, and Realtor.com housing market research publishes metro- and county-level data for your own market.
Should you buy now or wait for rates to drop?
It depends on your timeline and local inventory, and waiting trades one risk for another. Lower rates hand every competing buyer roughly 10% more purchasing power at the moment you get it, which historically shows up as more competition and firmer prices, not discounts. You can refinance a rate later; you can’t refinance the price you paid.
Align Lending does not forecast rates or prices, and you should be skeptical of anyone in the mortgage business who does. Fannie Mae’s Economic and Strategic Research Group, the Mortgage Bankers Association and NAR all publish forecasts and all revise them regularly, treat any of them as a planning assumption with a wide error band. What you can control is the structure of the deal.
- Lock, then refinance later: A rate lock fixes your pricing while your file clears underwriting, so a mid-process rate move can’t reprice the loan. If rates later fall meaningfully, a rate-and-term refinance captures it. Our guide to the benefits of mortgage rate locks covers lock periods, float-downs and extension costs.
- Buy down the rate: Discount points lower the note rate permanently; a temporary buydown lowers it for a year or two. On a $240,000 loan, a 2-1 buydown off a 7% note rate would cut the payment about $308 a month in year one and $158 in year two. Roughly $5,600 a seller can fund from concessions instead of a price cut.2
- Widen your range downward, not upward: Since a point of rate costs about 10% of purchasing power, shopping 10% below your maximum is the cleanest hedge against a rate move before closing.
- Check assistance programs first, not last: Down payment assistance cuts the cash you need at closing without touching your rate. See first-time home buyer grants and programs.
Holding off is always legitimate. If your job is unsettled, reserves are thin, or you may move within three years, waiting is often right regardless of rates.
What Michigan buyers should know
Michigan sits in the region that held up best on price through the high-rate stretch, on a much lower price base than the national median, which shifts the arithmetic in your favor.
- Michigan’s census division led the country at 4.5%: FHFA’s second-quarter 2026 index put East North Central (Michigan, Ohio, Indiana, Illinois and Wisconsin) first among all nine census divisions at 4.5% year-over-year appreciation, against 2.1% nationally. Midwest values proved more resilient than the coasts, not less.
- A lower price base softens every rate move: On a $300,000 Michigan purchase with 20% down (a $240,000 loan) one point of rate moves the payment about $158 a month rather than the roughly $197 it moves on a $300,000 loan.3 The same rate stretches further here than against the $434,100 national median.
- MSHDA offers up to $10,000 in down payment help: The Michigan State Housing Development Authority’s MI 10K DPA Loan provides up to $10,000 toward down payment, closing costs and prepaids as a 0% non-amortizing second mortgage with no monthly payment, repaid when you sell, refinance, pay off the first mortgage or stop living in the home. It pairs with the MI Home Loan and requires homebuyer education. Income limits, sales-price limits, credit-score minimums and a liquid-asset cap also apply, and MSHDA revises them, confirm current terms with MSHDA or a participating lender before you budget around them.
- Michigan law bars local rent control: Under MCL 123.411, enacted as 1988 PA 226, no Michigan local government may enforce an ordinance controlling the rent charged on private residential property. If your plan is to rent until rates fall, no Michigan city can cap your landlord’s increases.
Because Align is a broker, we can place MSHDA loans alongside conventional, FHA, VA and USDA options and weigh each against a seller-funded buydown, usually the comparison that decides which structure wins.
How Align reads the local market
National headlines rarely describe Oakland County. Samantha lives and works here, follows what homes in these neighborhoods actually sell for, and builds your loan around that, not around a national average.
Speed counts in a market where good homes go quickly. Over the last 12 months, her loans averaged under 14 days from application to clear to close, across more than 100 loans.

FAQ: Interest rates and home prices
Here are answers to common questions about interest rates and home prices.
Do home prices fall when interest rates rise?
Rarely by much. Higher rates cut what buyers can afford, so growth slows and some markets decline, but owners holding much lower rates have little reason to sell, which keeps inventory tight. FHFA research found the supply that lock-in froze between mid-2022 and the end of 2023 pushed values up 5.7% while higher rates pushed them down 3.3%. Expect flat-to-slow growth with far fewer sales, not a crash. Our Housing Market Trends hub tracks how those signals diverge.
How much does a 1% interest rate change affect my payment?
On a $300,000 30-year fixed loan, roughly $200 a month, or about $71,000 in added interest over the full term. On a $375,000 purchase, a 3% price cut saves about $57 a month while one point of rate is worth about $193, which is why waiting for a lower price while rates climb usually backfires. Our guide to mortgage rate buydowns compares points against a temporary buydown.
Should I wait for rates to drop before buying a home?
It depends on your timeline and local inventory. Lower rates give every competing buyer about 10% more purchasing power the same moment you get it, so falling rates typically bring more competition and firmer prices rather than discounts. Buying now and refinancing later preserves your options; you can’t refinance a purchase price. Our guide to the benefits of mortgage rate locks covers protecting pricing mid-process.
Why did mortgage rates stay high after the Fed cut rates?
Because they measure different things. The FOMC sets a target range for the federal funds rate, an overnight bank-to-bank rate. Your mortgage rate tracks the 10-year Treasury yield plus a spread priced in the mortgage-backed securities market, and long yields move on inflation expectations and global demand for U.S. debt. Mortgage rates can therefore hold flat or rise on the day the Fed cuts. Our guide to the Federal Reserve and mortgage rates walks through each step.
The bottom line on interest rates and home prices
Interest rates affect home prices indirectly, by setting what buyers can bid, and they hit your payment far harder than the price tag. On a $300,000 loan, one percentage point is worth about $200 a month, roughly $71,000 over 30 years, and about 10% of your purchasing power; a 3% price change on the same home is worth under $60 a month. Prices rarely fall as far as affordability suggests, because higher rates freeze supply faster than they cool demand. Focus on the payment you can carry.
