The Quick Read: As of September 28, 2026, the 30-year average has climbed in each of the last four weekly releases, and it has now passed 7%. If you are about to close, the payment you planned around may be moving unless your rate is locked. The good news is on the other side of the table: more inventory, more price cuts and heavy builder incentives give movers real room to negotiate.
Key Takeaways
- Freddie Mac’s survey put the 30-year fixed at 7.03% for the week of September 24, 2026, up from 6.95% the week before.
- The daily and weekly rate measures disagree on level because they measure different things. The direction is the same.
- Existing-home supply reached 4.9 months in August, and 66% of builders used incentives in September. That is leverage for buyers.
- If you have a signed contract and have not locked, that is the first call to make.
- Homeowners with private mortgage insurance may hear from their servicer soon. It is outreach, not automatic cancellation.
What Changed This Month
Rates rose four weeks in a row. That is the fact. Here is the run, straight from Freddie Mac’s weekly releases:
- September 3: 6.71%, up from 6.66% the week before.
- September 10: 6.76%, a 5 basis point rise.
- September 17: 6.95%, a 19 basis point rise.
- September 24: 7.03%, an 8 basis point rise.
That is 37 basis points in four weeks. A basis point is one-hundredth of a percentage point, so this is more than a third of a point. The 7.03% reading is the first time the survey has passed 7% since January 2025. A year earlier the same survey averaged 6.30%.
Now the wrinkle. Freddie Mac’s number is an average of rates offered from the prior Thursday through Wednesday, so it lags. Mortgage News Daily says its daily index broke 7% on September 10, right after the inflation reports. As of September 28, that index shows the average lender at 7.50%, the first time since April 30, 2024. The Mortgage Bankers Association’s weekly survey, released September 23, had its 30-year contract rate at 7.12% for the week ending September 18, up from 6.97%.
Three numbers, three levels. None of them is wrong. One is a weekly average of a specific loan type, one is a survey of applications, and one is built from lender rate sheets. Freddie Mac notes its survey covers conventional, conforming, fully amortizing purchase loans for borrowers with 20% down and excellent credit. Your loan may not look like that. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What pushed rates up?
Not just the Fed. The Federal Reserve raised its target range by 25 basis points on September 16, to 3.75% to 4%. In June it had held at 3.50% to 3.75%. CNBC reported the vote was unanimous and that updated projections point to the possibility of another increase this year.
But Mortgage News Daily points to inflation reports and Treasury yields as the drivers, not the Fed decision alone. NPR ties the climb since March to the war with Iran, bond-market volatility and inflation worries. Realtor.com’s senior economist said the 10-year Treasury surged to a 19-year high this week. That figure is second-hand, so I treat it as a signal, not a measurement.
What Is Happening to Demand?
Buyers are pulling back. The Mortgage Bankers Association reported that for the week ending September 18, total applications fell 1.5%. The refinance index fell 3% and sits 62% below a year ago. The seasonally adjusted purchase index fell 1%, and the unadjusted purchase index was 11% below a year ago.
NAR’s existing-home sales report, released September 10, showed August sales down 2% from July to a 3.98 million annual pace. Inventory rose to 1.62 million homes. Supply reached 4.9 months, and the median price was $429,100. NAR’s chief economist said months of supply is the highest in over ten years. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
One caution: pending sales are muddy. NAR’s own page shows August pending sales up 0.3%, while trade press describes buyers as more selective. Check the definition before you lean on either reading.
What Does It Mean for Home Buyers Who Are About to Close?
If you are locked, you are insulated. If you are not, you are exposed. That is the whole story for most people in this position.
A rate lock is a written commitment from the lender to hold a specific rate for a set period while your loan is processed. It protects you when the market rises. It does not help you if the market falls, unless your lock has a provision for that. Ask what yours says.
Here is a plain hypothetical. If a rate moves from 6.75% to 7.25% between contract and closing, that half point changes the monthly cost of the loan for as long as you hold it. I am not giving you a payment figure, because I do not know your loan. The point is that a move like September’s is not a rounding error.
Three practical things for a buyer under contract:
1. Find out today whether you are locked. If you are not, ask your loan officer or broker what the lock terms would be. If you like the number and the deal, lock it. Floating is a bet, and this month the bet has lost four weeks running.
2. Do not compare quotes from different days. A quote gathered on September 10 and one gathered on September 25 are not the same market. Lay them side by side only if they were pulled the same day, on the same loan type.
3. Recheck what you qualified for. Approval was based on a rate that may no longer exist. Ask your lender to rerun your numbers at today’s market before you assume nothing changed.
I will say what I do not know: what your file looks like. Some borrowers will have room. Others will be close to a limit. Eligibility depends on lender guidelines, credit, income documentation and the property, and the loan options page carries the current guidelines.
Where Buyers Have Leverage
Rates are the bad news. Supply and seller behavior are the offset.
The inventory picture is getting friendlier. Realtor.com data, summarized by Calculated Risk, put active listings up 3.6% year over year in August. The share of listings with a price cut was 20.4% in August, matching last year for the first time in 2026, according to Inman’s report on the data. Existing-home supply of 4.9 months is well above what buyers faced a couple of years ago.
New construction is where the incentives are. The Census Bureau reported that August new-home sales rose from July but remained slightly below the level of August 2025. The monthly gain sits inside the survey’s margin of error, so do not read it as a recovery. New-home prices were lower than a year earlier, and inventory remained elevated, equal to a supply of more than eight months.
Builders know it. Per the NAHB and a large national bank index, 66% of builders used sales incentives in September, the highest share since December. And 38% reported price cuts, up from 35% in August. HousingWire reports builders have been buying down mortgage rates for buyers. A buydown is a payment from the seller or builder that lowers the buyer’s rate for a period, or for the life of the loan.
Realtor.com’s seasonal analysis names September 27 through October 3 as the best week to buy this year, citing elevated inventory and less competition. Take that as a marketing-adjacent read, not gospel. But the direction fits the data.

A warning about “buyer’s market”
Do not overread this. Active listings are still 11.1% below pre-pandemic levels nationally. More inventory than last year is not the same as plenty. And these are national numbers. Your local market can look very different, and I will not pretend one figure describes it.
My Take
I think the rate story and the leverage story are the same story seen from two sides. Buyers are stepping back because the cost of money went up. Sellers and builders are answering with price cuts and incentives because buyers stepped back. That is a market clearing, not a market breaking.
For a buyer with a signed contract, my read is simple: the rate is the piece you can control, and the price is the piece you may still be able to negotiate. Use the second to make up for the first where you can.
For a buyer still shopping, the honest answer is that nobody knows where rates go from here. The Fed’s dot plot suggests year-end projections between 4.1% and 4.4% for the funds rate, and one outlook notes there is no FOMC meeting until late October. Forecasts are a poor basis for a home purchase. I would rather a buyer decide on what they can carry than on what they hope will happen.
I keep coming back to one point. Waiting for rates to fall is a rate call. Buying a home you can hold through a range of rates is not. The second is the safer plan.
What About Owners Who Are Already Settled In?
A policy note that matters for people who bought recently or a while ago. The Federal Housing Finance Agency’s director said Fannie Mae will align with Freddie Mac’s policy letting servicers contact borrowers who may qualify to cancel private mortgage insurance, as HousingWire reported in mid-September.
Private mortgage insurance, or PMI, is coverage many borrowers pay for when they put down less than a full down payment. It protects the lender, not you.
Read the fine print. This is about outreach, not automatic cancellation, and existing eligibility rules still apply. No implementation date or savings estimate has been provided. So do not assume a change is coming to your bill. If you have PMI and your home has appreciated or your balance has dropped, it is reasonable to ask your servicer now what it takes to cancel.
On equity more broadly: an industry white paper reported homeowners held $34.9 trillion in equity in the first quarter of 2026, about $11 trillion of it tappable. That is an industry estimate, not a government dataset. But it explains why second-lien products are drawing attention. If you are considering tapping equity, the rate environment matters for that too, and the same lock-and-compare discipline applies. Our piece on refinancing a vacation home into a DSCR loan covers one route for investors.
One gap I should name. I found no fresh public data on self-employed bank-statement lending or investor loan volume this month, so I will not guess at it.
What I’d Do Now
None of this is advice to buy or sell. It is how I would sequence the decisions.
- Under contract and unlocked: get a lock conversation on the calendar today.
- Under contract and locked: confirm the lock covers your closing date. Then negotiate anything the seller or builder is still willing to give.
- Shopping: compare quotes pulled on the same day, and treat builder incentives as part of the price, not a bonus.
- Building or buying new: ask what incentives are on the table and whether they change with the loan you choose.
- Owning with PMI: call your servicer and ask what cancellation requires.

Frequently Asked Questions
Have mortgage rates really risen four weeks in a row?
Yes, by Freddie Mac’s weekly survey. The 30-year average went from 6.71% on September 3 to 7.03% on September 24. One trade outlet counted five weeks, but I could not confirm a fifth rise in Freddie Mac’s own releases, so I say four.
Why do Freddie Mac, the MBA and Mortgage News Daily show different rates?
They measure different things. Freddie Mac averages the rates offered over several days on a specific loan type. The MBA reports figures drawn from its application survey. Mortgage News Daily builds a daily index from lender rate sheets, so it moves first. The gap is a matter of method, not error.
Should I lock my rate now or wait for it to drop?
If you like the deal and can carry the loan, lock. Floating is a bet on the market, and forecasts are unreliable. There is no FOMC meeting until late October, and the Fed’s own projections leave room for another increase this year. Ask your lender what your lock terms include.
Is this a buyer’s market?
Partly. Supply is 4.9 months and 20.4% of listings carry price cuts, which helps buyers. But active listings are still 11.1% below pre-pandemic levels nationally. It depends on your local market.
Will the new PMI policy cancel my mortgage insurance automatically?
No. It lets servicers contact borrowers who may qualify to cancel. Existing eligibility rules still apply, and no implementation date has been announced. Ask your servicer what it would take in your case.
