The Quick Read: Mortgage rates rose in every September survey, and the Fed raised its target range on September 16. As of September 28, 2026, the trend points up, not down. If you have a tight debt-to-income ratio and you float your rate hoping for relief, my read is that a gap up is more likely than a gap down. If you like the house and the numbers work today, lock.
Key Takeaways
- Freddie Mac’s weekly survey put the 30-year fixed at 7.03% for the week of September 24, 2026, up from 6.95% the week before.
- The Fed raised its target range by a quarter point on September 16, its first hike since 2023.
- The 10-year Treasury yield hit its highest level since 2007 on September 25, which is the number mortgage rates track.
- Inventory is at a ten-year-plus high and sales are soft, so buyers have room to negotiate on price. Price is not the same as rate. “Shop around and wait” was reasonable advice a month ago. In a rising trend, floating is a bet, and a tight budget is a poor place to make one.
What Changed?
Rates moved up four times in a row, and the last two moves were the ones that hurt. Here is the sequence from Freddie Mac’s weekly survey, the standard public benchmark for the 30-year fixed.
| Survey week | 30-year average | Move |
|---|---|---|
| Sept 3 | 6.71% | up 5 bp |
| Sept 10 | 6.76% | up 5 bp |
| Sept 17 | 6.95% | up 19 bp |
| Sept 24 | 7.03% | up 8 bp |
A basis point is one hundredth of a percentage point. The August 27 reading was 6.66%, so the average is up 37 basis points in four weeks. A year ago, Freddie Mac’s survey for the week of September 24 had the 30-year at 6.30%. That is a 73 basis point gap.
The big single move came in the survey released September 17, which showed 6.95% against 6.76% the week before. That is 19 basis points in one reading.
Freddie’s survey is a weekly average, so it lags. On September 24, CNBC reported that Mortgage News Daily’s index rose to 7.45%, up 19 basis points from 7.26% the day before. In the same report, Mortgage News Daily said 7% was first broken in daily terms on September 10. Freddie’s average did not print above 7% until two weeks later. If you were watching the weekly headline, you were behind the market.
The Mortgage Bankers Association tells the same story from its own survey. In the week ending September 18, the MBA’s weekly applications report put its average 30-year contract rate at 7.12%, up from 6.97%. Refinance applications were 62% below a year earlier. Purchase applications, unadjusted, were 11% below the same week last year.
Three readings, three numbers
People compare these figures and think somebody is wrong. Nobody is. They measure different things on different days.
| Measure | Publisher | Reading |
|---|---|---|
| Weekly average | Freddie Mac | 7.03%, week of Sept 24 |
| Weekly contract rate | MBA | 7.12%, week ending Sept 18 |
| Daily index | Mortgage News Daily | 7.45%, Sept 24 |
Freddie’s survey covers conventional, conforming purchase loans for borrowers with a sizable down payment and excellent credit. That is a clean-file benchmark. It is not a quote for a borrower with tight income ratios, and it is not a quote for anyone in non-QM. Read it as a direction, not as the number you will see.
The Fed, and what it did and didn’t do
On September 16, the FOMC voted 12–0 to raise the target range by a quarter point, to 3-3/4 to 4 percent. The statement says inflation remains elevated. CNBC’s coverage called it the first hike since July 2023 and noted that 16 of 18 participants expected another increase.
Here is the part people get wrong. The Fed does not set mortgage rates. Mortgage rates follow the bond market, and the 10-year Treasury is the closest public gauge. CNBC reported on September 23 that the 10-year yield jumped more than 13 basis points to 5.104%, a level not seen since July 2007. The same report said CME FedWatch odds of an October hike rose to 66.4% from 55% the day before.
The move kept going. CNBC’s September 26 report put the 10-year at 5.23% on Friday, September 25. Earlier in September it traded just below 4.8%. That is roughly 43 basis points in about three weeks. Reports attribute the spike to strong economic data, oil, and weak demand at a Treasury auction, not to the Fed hike alone.
What Does This Mean for Home Buyers?
It means the cost of waiting just went up, and the market that rewards patience is a market where rates fall. That isn’t this one. The housing side of the ledger is softer than the rate side, and that is where your leverage is.
NAR’s report on August existing-home sales, released September 10, showed sales down 2.0% from July and 1.2% from a year earlier. The seasonally adjusted annual rate was 3.98 million. Inventory hit 1.62 million units, up 5.9% from a year earlier, and supply reached 4.9 months, the highest in over ten years. NAR’s chief economist said ample supply gives buyers better opportunities to negotiate.
The listing data agree. According to Realtor.com data reported by WRE News, inventory for the week of September 19 was up 5.8% from a year earlier. The median listing price was $419,500, down 1.3% year over year, the 36th straight week of annual declines. On new construction, Inman reported that the average new-home price fell 8.8% from a year earlier and builders are increasing incentives.
So buyers have real room on price. I would not oversell it, though, for three reasons.
- NAR’s median price is still up. The median existing-home price was up 1.6% from a year earlier per NAR’s snapshot. Listing prices and sale prices are different series.
- The data lag the rate move. Pending sales rose 0.3% in August. Those contracts were signed at rates well below today’s. We haven’t seen how buyers respond to a 7% market yet.
- Census urges caution on new-home sales. August’s new-home sales ran at 684,000, up 6.4% from July. The margin of error is large enough that Census does not treat the change as statistically significant. Don’t read a rebound into it.
The Realtor.com research release from September 10 pegged September 27 through October 3 as the best balance of inventory and competition this year. It also said mortgage rates are above year-ago levels and offer buyers little financing relief. That last line is the honest one. You can negotiate price. You cannot negotiate the bond market.
Why Does Floating Fail a Tight Budget?
A float only wins if rates fall before you lock. In a rising trend the odds tilt the other way. And if your debt-to-income ratio is tight, the two outcomes are not symmetric. A drop helps you. A jump can push the file out of range.
Debt-to-income, or DTI, is your monthly debts divided by your monthly gross income. Lenders use it to judge whether you can carry the payment. Some buyers sit close to the edge of what a program allows. For them, a rate move of a quarter point is not an inconvenience. It can decide whether the file works.
Run a plain hypothetical. Say a rate moves from 7% to 7.25% while a buyer floats. That is a quarter point. Freddie’s survey rose 19 basis points in a single reading on September 17. Two readings like that and a float has cost you 38 basis points. For a borrower with room to spare, that is annoying. For a borrower at the edge, it is a different loan or no loan.
Now the other side of the bet. For the float to pay off, rates have to drop by enough to matter before your lock date. What would drive that? A softer inflation print. A pause from the Fed. A calmer Treasury market. Any of them could happen. But the CME odds cited by CNBC put an October hike at about two in three, and the next FOMC meeting is October 28. The sources I’ve read disagree on how much further the Fed goes. That disagreement is the point: the path is uncertain, and floating means you carry that uncertainty.
Here’s my read, and it is an opinion. When the trend is up and your budget is tight, the expected outcome of floating is a worse rate, not a better one. Not certain, but tilted. And the two outcomes are not equal in size for you. A gain is a nice bonus. A loss can end the deal. That is a bad bet to take with a home purchase, where the price and the house are already what you are negotiating.
There is one honest exception. A buyer with lots of room in the file and a long runway before closing can float and absorb a bad outcome. That buyer is not the one I’m writing to.
What a lock is, and what it isn’t
A lock is a written commitment from the lender to hold a set of loan terms for a defined period, so long as the loan meets the conditions attached to it. It does not improve those terms. It keeps pricing from shifting against you while the deal works through review, appraisal and closing steps.
Two mechanics matter this fall.
1. Locks expire. Ask how long a lock runs and compare that against your contract dates. An extension can cost money. A lapse can mean re-pricing at whatever the market is then.
2. Quotes are not comparable across days. A quote gathered on September 10 and one gathered on September 24 sit in different markets. If you are comparing offers, compare them on the same day, or you are comparing the calendar, not the lender.
That second point is why I think the old “get multiple quotes” advice is incomplete in a rising month. On September 10, Freddie Mac’s chief economist said shopping around and getting multiple quotes can potentially save thousands, in that week’s release. It is sound advice. Shopping still matters. But the rate rose 19 basis points in the very next survey. A month of shopping and waiting can cost more than the shopping saves. Shop in a day or two, then decide.
My Take
The autumn story is two markets pulling in opposite directions. Housing is loosening. Money is tightening. Sellers have more inventory and fewer buyers. Buyers have more choice and a higher cost of borrowing. The winners are buyers who use the first to offset the second, and who don’t try to time the bond market on top of it.
Three opinions, clearly labeled as mine.
Negotiate the price, not the calendar. With supply at a ten-year-plus high, the seller’s leverage is thinner than it was in the spring. That is where a buyer earns something real. It is worth more than a guess about next month’s rate.
Treat a rate as a fact, not a forecast. If the rate today works for your budget with room to spare, that is your answer. Don’t bet that it will improve. If it does not work at today’s rate, waiting for a drop is a plan with no support in the current data.
Don’t confuse the headline with your loan. Freddie’s 7.03% is a clean-file average. Yours could be higher or lower. Your file, your down payment, your credit, your property and the day you price it decide that. Nobody can tell you from a national survey.
I’d also caution against one popular idea: that a non-QM loan is a way around the rate market. It isn’t a hedge. Non-QM pricing moves with the market too, and I have no source showing it is insulated. Where non-QM fits is on how a borrower qualifies, not on where rates sit. If you’re self-employed or investing, our loan options page describes what each program is reviewed on, and it carries the current guidelines, subject to lender guidelines. It is also worth knowing that, per an Optimal Blue analysis published by KESQ on September 28, conforming loans held 47% of August lock volume, no longer a majority, and investor and DSCR loans exceeded 35% of non-QM production. Buyers are moving toward loans that fit their file. For investors, our DSCR loans guide explains how a rental’s income drives the qualification.
What I’d Do Now
This is general education, not advice to buy or sell any particular home. Here is the order I would work in if I were buying this autumn.
1. Check your DTI before you fall in love. Add your monthly debts, divide by gross monthly income, and know how much room you have. If the answer is “not much,” the float is off the table.
2. Get your paperwork in order first. Pay stubs, bank statements, tax documents if they apply, and a clear explanation of any large deposit. A file that is ready is a file that can lock the moment you have a contract.
3. Ask for quotes on the same day. If you’re comparing, compare like with like. Ask each source what the quote assumes, and how long a lock would hold.
4. Decide your lock rule before the market decides for you. Mine is simple: if you like it, lock it. Once you have a contract and the numbers work at today’s rate, the case for floating is thin.
5. Spend your negotiating energy on price and terms. Supply is up and listing prices are falling year over year per Realtor.com data. Ask for what the market gives you, and let the rate be the rate.
6. Keep a cushion. If a rate at the edge of your comfort is the only rate that works, that is worth a second look at the price range.
7. Watch two dates. The next FOMC meeting is October 28. NAR’s September existing-home sales come out October 13. Neither one is a reason to wait. They are reasons to be ready.
Some buyers should wait, and that is fine. If the numbers don’t work today and there is no room in your budget, waiting can be the right call for reasons that have nothing to do with rates. Just don’t call it a strategy that depends on a decline.

Frequently Asked Questions
Is 7% the rate I’ll get on a mortgage right now?
Not necessarily. Freddie Mac’s 7.03% for the week of September 24 is a weekly average for conventional, conforming loans with a sizable down payment and excellent credit. Mortgage News Daily’s daily index was higher that day, at 7.45%. Your own figure depends on your file and the day you price it.
Did the Fed’s hike cause mortgage rates to jump?
Only partly, and indirectly. The FOMC raised its target range on September 16, but mortgage rates follow the bond market, and the 10-year Treasury did most of the moving. Reports tie the September spike to strong data, oil and a weak Treasury auction. The hike added to the mood, but it was not the only driver.
Is autumn still a good time to buy?
For price and choice, yes. NAR reported supply of 4.9 months in August, the highest in over ten years, and Realtor.com data show listing prices down year over year. For financing, it’s the hardest stretch of the year so far. Those two facts pull against each other, which is why the decision belongs to your budget, not the calendar.
What does “lock it” actually protect me from?
A lock holds a quoted rate for a set period, so a rising market can’t change the rate mid-transaction, provided your loan meets the lock’s terms. It doesn’t lower the rate and it doesn’t last indefinitely. Ask how long it runs and what an extension would cost before you commit.
