Mortgage Rates and Home Prices: The 30-Year Tops 7% Again — What to Expect in 2027

The average 30-year fixed mortgage rate hit 7.28% this week (Freddie Mac, October 1, 2026) — the highest since November 2023. Yet the median existing home still sold for $429,100 in August, up 1.6% from a year ago.

Rates have more than doubled since 2021, and they just jumped again. So why aren’t prices falling? Here’s the mechanism behind it, the current numbers on both sides, and what forecasters now expect for 2027.

Where Rates and Prices Stand Right Now (October 2026)

Mortgage rates have climbed six weeks in a row. Freddie Mac’s survey put the 30-year fixed at 6.76% on September 10, 6.95% on September 17, 7.03% on September 24 and 7.28% on October 1.

That last 25-basis-point jump was the biggest one-week rise since October 2022. The 15-year fixed rose to 6.60%, up from 6.42% a week earlier.

What’s driving it:

• Sticky inflation. Consumer prices were still running about 3.4% a year in July.
• The Fed’s September hike. It raised its benchmark rate a quarter point and signaled another hike is likely this year.
• Bond market nerves. The 10-year Treasury, which mortgage rates track closely, has pushed above 5%.

On the price side, NAR’s August report put the median sale price at $429,100, up 1.6% year-over-year. That’s down from June’s $440,600, but that’s the normal seasonal dip after the spring and early-summer peak, not a crash.

Sales are slowing, though. Existing-home sales fell 2.0% in August to a 3.98 million annual pace, down 1.2% from a year earlier.

The Case-Shiller National Home Price Index tells the same story. It rose 1.9% year-over-year in July 2026, up from 1.6% in June. With inflation near 3.4%, home values have now fallen in real terms for 14 straight months, even as the dollar price keeps edging up.

Why 7% Rates Still Haven’t Pushed Home Prices Down

Basic intuition says higher rates should cool demand and pull prices down. That hasn’t happened, and the main reason has a name: the lock-in effect.

During 2020–2021, tens of millions of homeowners bought or refinanced at rates between 2.5% and 4%. Selling today means giving up that rate and borrowing again at well over 7%. For a lot of owners, that math doesn’t work.

Consider Priya, who refinanced in 2021 at 3.2%. She and her husband would like a bigger place now that they have a second child.

But a similar home at today’s rates would raise their monthly payment by well over $1,100, even before the higher purchase price. They’re renovating instead.

Millions of households are making the same call, which is why so few move-up homes hit the market. Demand hasn’t collapsed either. Household formation and a years-long shortfall in new construction keep a floor under prices.

Inventory is finally loosening — slowly

Here’s the one number that has really changed since summer. Inventory reached 1.62 million homes in August, a 4.9-month supply. That’s the highest in more than a decade, and up from 4.6 months in June.

A market is usually considered balanced at 5–6 months. We’re now right at the edge. That’s why price growth has slowed to under 2%, and why Fannie Mae expects it to slow to roughly 1% in 2027.

There’s a legislative angle too. The 21st Century ROAD to Housing Act, signed into law in July 2026, targets some supply bottlenecks. It’s still too early to see it move the inventory numbers.

What 7%+ Rates Cost You Every Month

The rate gap is real money. Here’s the principal and interest on a $400,000, 30-year loan:

Going from a 2021-era 3.5% rate to today’s roughly 7.25% adds about $933 a month on the same loan. It also more than doubles the lifetime interest. Even versus the 6.5% rates of this summer, today’s borrower pays about $200 more per month.

Take Marcus, who got pre-approved in July at 6.6% for a $400,000 loan. If he locks this week near 7.3%, his payment rises by roughly $190 a month. That’s about $2,250 a year for the same house.

For buyers who are close to their limit, that’s often the difference between qualifying and not.

15-Year vs. 30-Year at Today’s Rates

The 15-year fixed is at 6.60%, about 0.7 points below the 30-year. On the same $400,000 loan, the 15-year payment is about $3,506 a month versus roughly $2,737 for the 30-year.

That’s about $770 more each month. In return, you’d pay around $231,000 in total interest instead of roughly $585,000. The 15-year builds equity much faster, but the higher payment is a real affordability hurdle right now.

My full 15-year vs. 30-year mortgage comparison walks through the math on both, including when paying extra on a 30-year gets you most of the benefit.

Does Refinancing Make Sense With Rates Above 7%?

For most homeowners, no. If you’re locked in at 3%–5%, there’s no rate-driven reason to refinance today. The math only works if your current rate is roughly a full point or more above today’s, after closing costs.

That mostly means people who bought in late 2023, when rates briefly hit about 7.8%. If that’s you, keep an eye on rates rather than acting now. I’ve covered when refinancing actually pays off in Should I Refinance My Mortgage and Do I Qualify?

If you’re sitting on a lot of equity and thinking of selling instead, remember the $250,000/$500,000 home sale capital gains exclusion. It hasn’t been adjusted for inflation since 1997, so long-time owners can face a bigger tax bill than they expect. My capital gains tax rates guide covers how any gain above the exclusion is taxed.

Mistakes I See Buyers Make When Rates Jump

Assuming a rate spike means prices will crash. They can move in opposite directions, but this cycle they haven’t. Inventory is the bigger driver, and at 4.9 months it’s loosening, not flooding.

Letting a rate lock expire. With rates moving 20–25 basis points in a week, a lapsed lock can cost real money. If you’re under contract, ask your lender about lock length and extension fees up front.

Ignoring debt-to-income limits. A higher rate can push your payment past what a lender will approve, even if your pre-approval letter says otherwise. Ask your lender to re-run your numbers at today’s rate before you make an offer.

Treating the Case-Shiller Index as a dollar figure. The index tracks the change in repeat-sale prices, not an actual price. Use NAR’s median ($429,100) or local comps for dollar amounts.

Not shopping multiple lenders. Freddie Mac’s own research shows real rate differences between lenders for the same borrower. Getting 3–4 quotes is one of the few free ways to lower your rate, and it matters more when rates are high.

What I’m Watching for Mortgage Rates and Prices in 2027

Forecasters have turned noticeably less optimistic since summer. Fannie Mae’s September outlook has the 30-year near 6.7% in every quarter of 2027, with home price growth slowing to about 1%. Back in July, it was calling for 6.3%–6.4%.

The Mortgage Bankers Association raised its outlook to about 6.8% through mid-2027. It now expects two more Fed hikes over the next year. No major forecaster is calling for a return to the 3%–5% range.

Key dates on my calendar:

• October 28: Fed decision. Goldman Sachs and Bank of America expect another quarter-point hike, but markets see it as roughly a coin flip.
• Late October: NAR’s September existing-home sales and the next Case-Shiller release.
• December 9: The final Fed meeting of 2026, with new rate projections for 2027.

My take: as long as inflation stays above 3%, the Fed is more likely to hike than cut, and that keeps mortgage rates high. On prices, rising inventory points to flat-to-slightly-higher prices in 2027, not a sharp drop. I’ll update this page as the Fed and NAR numbers come in.
