The Quick Read: The Fed raised its target range by a quarter point on September 16, 2026, and mortgage rates were already climbing before it did. Freddie Mac’s 30-year average has now risen six weeks in a row. Budget for a higher payment than the spring checklist assumed. Then use the leverage that rising inventory and builder discounts give you.
This column is dated as of September 28, 2026, with data updated through October 1. Here’s what changed, what it means for a buyer’s budget, and what I’d do before touring a single house.
Key Takeaways
- The Fed’s hike was real, but mortgage rates track long-term Treasury yields more than the fed funds rate. They were rising before the Fed moved.
- The streak is longer than the “four weeks” you may have heard. Freddie Mac’s average has risen six straight weeks.
- Stress-test your budget against a range of payments, not today’s number.
- Buyers have more negotiating room than in years. Higher rates limit how much of it you can use.
- Plan for a range of outcomes. Don’t try to time the market.
What changed in September
The Fed hiked on September 16. At that meeting the FOMC raised the target range by a quarter point, to 3¾–4 percent, per Chairman Warsh’s press conference. CNBC reported a 12-0 vote and called it the first increase since 2023. The Fed’s updated projections also point to the possibility of another hike this year.
Now the mortgage side. Freddie Mac’s survey put the 30-year fixed at 6.71% for the week of September 3, up 5 basis points from the prior week, per its release. A basis point is one-hundredth of a percentage point.
Two weeks later came the big move. Freddie Mac’s average rose 19 basis points to 6.95%, the largest weekly jump since April 2025, as Fox Business reported on September 24. The next week it topped 7% for the first time since January 2025.
Then came October 1. Freddie Mac’s survey put the 30-year fixed at 7.28% for that week, up from 7.03%. That is the highest since November 2023. A year earlier the average was 6.34%.
CNN counts six straight weekly increases. The first four came before the Fed acted.
The Mortgage Bankers Association tells the same story. In its survey for the week ending September 25, released September 30, applications fell 6.0%. The MBA’s 30-year rate rose for a sixth week to 7.3 percent, the highest since November 2023. ARMs reached 10.3 percent of applications, the highest share since October 2025.
Different surveys use different methods, so their numbers differ a little. I name the publisher each time for that reason.
Did the Fed Raise My Mortgage Rate?
Not directly. Mortgage rates follow long-term yields, especially the 10-year Treasury, more than the fed funds rate. Realtor.com’s economist attributed the September 17 jump mainly to the 10-year, per Fox Business on September 24.
The Federal Reserve’s H.15 series shows the 10-year at 5.11 on September 23 and 5.26 on September 29. That’s a 15 basis point climb in a week.
Sources disagree on cause and effect. Some frame the Fed as following the bond market. The rise in yields also reflects oil prices, inflation and fiscal worries, per CNBC on October 1. I won’t pretend to know how much is the hike and how much is the bond market.
My read: don’t wait for the Fed to “fix” this. The Fed isn’t the only driver, and yields can reverse on a headline. One strategist told CNBC the 10-year could ease if a U.S.-Iran deal ends the war. Zillow’s forecast has the 30-year at 7.1% by year-end. Neither is something to bank on.
What does a higher-rate market mean for your budget?
It means the payment you qualified for in March may not be the payment you’d carry today. Freddie Mac’s average was 6.22% on March 19, when it described a more affordable spring season than last year’s. It stood at 7.28% on October 1. That’s more than a full point.
Here’s a plain hypothetical. If a mortgage rate moves from 6% to 7%, you pay a meaningfully larger share of every payment in interest. A full point is a big move on a 30-year loan. It changes how much house the same income supports.
So the first job is a stress test. Take your budget and ask whether you can carry a payment at today’s levels, and then at a level higher still. If the answer is “barely,” you have your answer about how much to spend.
The MBA’s data show buyers are already adjusting. The unadjusted Purchase Index was 11 percent lower than a year earlier in the week ending September 18. Refinance activity is down 56% from a year ago, per the MBA’s September 30 release. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Where Buyers Have More Leverage Than the Spring Checklist Assumed
The legacy checklist was written for a different market. Buyers now have more choices and more room to negotiate. That is real, and the data back it up.
NAR’s existing-home sales report, released September 10, showed sales down 2.0% for the month. Inventory was 1.62 million, up 5.9% from a year earlier. Supply was 4.9 months, which NAR’s Lawrence Yun called the highest in over ten years. He said the ample supply is giving buyers better opportunities to negotiate.
Realtor.com’s September 30 data point the same way. The share of listings with a price cut was 20.8%, the highest for a September since 2018. Active inventory rose 5.4% from a year earlier, while homes under contract fell 4.1%. Redfin’s September 17 report had pending sales down 3.5% for the week to the lowest level in almost three years.
Builders are bargaining too. Census reported on September 24 that new-home inventory was 483,000, an 8.5-month supply, and the median new-home price was 5.8 percent below a year earlier. NAHB’s September index, per Inman, showed 38 percent of builders cutting prices and 66% using incentives, the highest incentive share since December.
One caution. Census says the monthly gain in new-home sales sits inside its margin of error, so don’t read “booming” into it. And “prices are falling nationally” is also too simple. NAR’s median existing price, $429,100, was still up 1.6% from a year ago.
Leverage is not affordability. Realtor.com’s chief economist, Danielle Hale, made that point on September 30: buyers are gaining leverage, but higher rates limit how much they can use. I agree. A seller’s concession helps. It doesn’t undo a payment you can’t carry.
My Take
My view is simple. The market gave buyers a better negotiating hand and took away cheap money in the same month. You get one, not both.
I’d stop asking when rates will fall. Nobody can say, and the forecasts conflict. I’d ask whether the purchase works across a range of rates. If it does, the rate is a detail you can revisit later. If it doesn’t, no seller credit will save it.
“Buy now before rates go higher” is also weak advice. The Fed’s projections point to the possibility of another hike this year, but the 10-year can reverse with the news. The evidence supports planning, not timing.
What I’d Do Now
Rerun your budget at a higher payment. Use today’s published market average, then a notch above it. Keep the result as your ceiling, not your target.
Check your credit and your debts before you shop. Pull your reports and fix errors. Hold off on new credit. Lenders weigh your monthly debts against your income, so paying down a balance can matter as much as saving more cash.
Decide how much cash you want left after closing. Down payment, closing costs and a reserve are three separate buckets. Don’t empty the third to fill the first.
Get pre-approved, then compare. Quotes gathered on different days aren’t comparable, because rates moved in the interim. Ask for them the same day, on the same terms. A broker such as us can place your file with several lenders and compare them side by side.
Understand the lock. A rate lock holds a rate for a set period so a move in the market doesn’t change your terms. If you like the house and the payment works, lock it. Floating is a bet that rates fall, and September showed what the other outcome looks like.
Look at the full menu. Our loan options page carries the current guidelines for each program, which are subject to lender guidelines and your file. Some buyers are looking harder at adjustable-rate loans. The MBA’s Joel Kan noted that ARM rates were about 80 basis points below fixed rates. That is a data point on behavior, not a recommendation, and an adjustable loan carries risk if rates stay high.
Use the leverage. Ask for price cuts, seller credits and builder incentives. Zonda’s late-September data showed 63% of new-home communities offering incentives on to-be-built homes. Treat the concession as a way to lower your cost of carrying the home, not a prize.
Plan for a refinance, but don’t count on one. Refinance applications are down sharply, and owners are making different lock decisions now. If you later refinance, the choice between pulling cash out and changing only your rate and term matters. I wrote about that in this piece on cash-out versus rate-and-term refinancing.
If you’re weighing a purchase or a refinance this fall, Lendmire can walk you through how the current programs fit your file.

Frequently Asked Questions
Did the Fed’s September hike cause mortgage rates to jump?
Only partly. Freddie Mac’s average rose each of the six weeks since August 27, and the first four of those readings came before the hike. Realtor.com’s economist pointed mainly to the 10-year Treasury for the September 17 jump. Sources disagree on how much is the hike and how much is bond-market forces.
Should I wait for rates to come back down before buying?
Waiting is a bet, not a plan. One strategist sees room for the 10-year to ease, and Zillow’s forecast is 7.1% by year-end, but neither is a prediction to rely on. Build a budget that works at a range of rates. Then decide on the house, not the calendar.
Is it a buyer’s market now?
Buyers have more leverage than they did, but it’s not the full story. NAR reported 4.9 months of supply on September 10, and Realtor.com showed the highest September share of price cuts since 2018. But Hale of Realtor.com cautions that higher rates limit how much you can use that leverage. And prices haven’t fallen everywhere, since NAR’s median existing price was up 1.6% from a year earlier.
When should I lock my rate?
Lock when the house and the payment both work for you. A lock protects you from a move in the market while your loan is in process. Floating only helps if rates fall, and the last six weeks went the other way. Ask your loan officer what lock options are available.
Do builder incentives make new homes the better deal?
They can, but compare the full cost. Census put the median new-home price at $393,700 on September 24, with new-home inventory at 483,000. NAHB’s index showed 66% of builders using incentives. HousingWire flagged margin risk for builders at current rates, so how long the incentives last is an open question.
