The Quick Read: As of September 28, 2026, a quote you collected three weeks ago is a historical document, not a price. Freddie Mac’s survey has the 30-year fixed average up four straight weeks, to 7.03% for the week of September 24. Daily data moved even more. My advice: talk to a handful of reputable lenders inside a few days, compare them, then stop shopping and lock.
Key Takeaways
- Freddie Mac’s 30-year average rose in the weeks of September 3, 10, 17 and 24, with the biggest jump on September 17.
- Freddie’s number lags the market. Mortgage News Daily’s index ran well above it in the same week.
- Quotes gathered on different days compare dates, not lenders.
- The cure is a short shopping window, then a lock.
- Investors and self-employed borrowers should shop the same way, with one extra step: compare programs, not just prices.
What Changed
The four-week climb is real, and the pace picked up in the middle. Freddie Mac’s release for September 3 put the 30-year fixed at 6.71%, up from 6.66% the week before. The September 10 figure was 6.76%. Then the September 17 release showed 6.95%, a 19 basis point jump and the largest of the run. The week of September 24 brought 7.03%.
That is 32 basis points in three weeks. A year earlier, the same survey read 6.30%, so the average is up 73 basis points year over year.
A basis point, for anyone new to the term, is one hundredth of a percentage point.
Freddie’s number is a lagging average. Freddie says its survey reflects rates offered the prior Thursday through Wednesday, and it covers conventional, conforming purchase loans with 20% down and excellent credit. It is not an investor-loan or non-QM measure. Treat it as a trend line, not today’s price. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Mortgage News Daily’s index shows the gap. On September 10, it put the average top-tier 30-year fixed at 7.07%, its highest since May 21, 2025. Freddie printed 6.76% that same week. By Thursday, September 24, Yahoo Finance, citing Mortgage News Daily, reported the index at 7.45% late in the day, after a 9 basis point jump Wednesday and 19 more Thursday. Freddie’s print for the week was 7.03%. That 42 basis point gap in one week is the whole staleness story.
The bond market is doing the work. CNBC reported on September 26 that the 10-year Treasury yield leapt to 5.23% on Friday, its highest since 2007. Earlier in September it traded just below 4.8%. Mortgage rates follow long-term yields more closely than they follow the overnight rate.
The Fed did add fuel. On September 16, the FOMC voted 12-0 to raise its target range by 25 basis points, to 3.75% to 4%, per the Federal Reserve’s implementation note. It was the first hike since 2023.
The Mortgage Bankers Association saw the same move in its own survey. Its 30-year conforming contract rate rose to 7.12% from 6.97% for the week ending September 18, per the MBA’s September 23 release. Three weeks earlier, for the week ending August 28, the MBA had it at 6.79%. That works out to about 33 basis points in three weeks, my arithmetic across two releases.
Why Do Quotes Go Stale So Fast?
A quote is a snapshot of one lender’s pricing on one day. Lenders reprice when the bond market moves, and some reprice more than once a day. Mortgage News Daily noted on September 10 that the average lender moved up an eighth of a point in rate in a single day.
Now picture the borrower with a spreadsheet. One quote is from September 3, another from September 10, a third from September 24. The September 3 lender looks like a bargain. It isn’t. It’s just older.
My inference from the Freddie and MBA series is plain: with both up roughly 32 to 33 basis points over three weeks, a quote from the start of September can’t be compared with one from the end. That’s my read, not a sourced claim. But the arithmetic is hard to argue with.
A quote is not a lock. A quote is information. A lock is a commitment, in which the lender agrees to hold a stated rate for a stated period under stated conditions. Many borrowers assume a quote protects them. It doesn’t. Ask each lender in writing what is locked, for how long, and what an extension costs.
Floating means you’ve chosen not to lock yet. In a market moving this way, floating is a bet that the direction reverses. Sometimes it does. Nothing in the September data says it will.
What It Means for Real Estate Investors
Investors feel this at the deal level. A rental that cleared your numbers in early September may not clear them now. Higher borrowing costs trim the cushion between rent and the loan payment. Run the deal again with a fresh quote before you assume anything.
There is a measurement problem, too. I found no public, non-lender dataset on DSCR or bank statement loan volume or pricing. The Freddie and MBA series don’t measure these borrowers. So treat the headline averages as direction only. The actual pricing on an investor loan depends on the borrower, the property and the program, subject to lender guidelines.
DSCR loans qualify a borrower on the property’s rental income rather than personal income documents, program-dependent. If you want to understand how the product works, the DSCR loan programs page carries the current guidelines. I won’t paraphrase figures here.
Short-term rental owners face a related question: what income a lender will count. I covered that in “What Counts As Short-term Rental Income for a Lender”. Sort that out before you collect quotes, not after.
What It Means for Buyers and Owners
The housing market is absorbing the shock slowly. NAR’s existing-home sales report, released September 10, showed August sales down 2.0% from July and 1.2% from a year earlier. The annual pace was 3.98 million, and HousingWire noted it was the first reading below 4 million since June 2025. Inventory stood at 1.62 million homes, a supply of 4.9 months, which NAR says is the highest in over ten years. The median price was up 1.6% from a year earlier.
Demand is cooling. The MBA’s release of September 23 showed the seasonally adjusted purchase index down 1% for the week ending September 18, and the unadjusted index 11% below a year earlier. The refinance index was down 3% on the week and 62% below a year ago. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
CNBC’s September 16 piece quoted a strategist saying owners with roughly 3% mortgages are unlikely to sell. So the first effect is a freeze in transactions. A Zillow economist told Yahoo Finance on September 24 that the bond turmoil is disrupting plans for shoppers hoping to buy late in the 2026 season.
My Take
Shopping is still right. Shopping slowly is the mistake. I’d rather a borrower talk to four reputable lenders in two days than eight over a month. The second approach feels thorough. It isn’t. By the time you finish, the first quotes are obsolete and you’re comparing a market that no longer exists.
I’m also skeptical of anyone who tells you where rates go next. The sources disagree. CNBC’s strategists say how long the 10-year stays above 5% matters more than the level itself. One outlet puts October hike odds near 70%, while another says the market prices one more hike in December. Both are unverified market pricing. Economists are split on whether the driver is growth or investor fatigue with U.S. debt. Candidates also include inflation, deficits, bond supply and oil.
Honestly, this is a toss-up. Yields could ease if the pressure fades. They could also keep climbing. Planning around a reversal you can’t see is how people end up locking at the top of a move they watched all month.
One more note on perspective. A 5% 10-year isn’t abnormal historically. What hurts is the speed, and the borrowers who anchored on lower rates. After eighteen years in lending, I can tell you the anchoring is the hard part. People negotiate with a number they saw in the spring.
What I’d Do Now
Shop in a tight window, then lock. Here’s the sequence I’d use.
1. Set your shopping window. Pick two or three days. Contact every lender in that span. Don’t extend it.
2. Ask for the same scenario from each. Same property, same loan type, same lock period. Otherwise you’re comparing different things.
3. Date every quote. Write the day and time beside each one. A quote without a timestamp is useless in this market.
4. Ask what is locked and for how long. Get the lock period and the extension terms in writing.
5. Decide, then lock. If you like the deal, lock it. Stop checking the daily index. The urge to wait for a dip is how a decent outcome turns into a regret.
6. Re-run your deal at the locked terms. If an investment doesn’t work at today’s cost of money, it didn’t work. Better to know before you commit.
This is where a broker earns the fee conversation. A broker who works with most DSCR and bank statement lenders can take much of that shopping out of the process, because one conversation reaches many programs at once. For self-employed borrowers, I’ve written about who is the best mortgage lender for self-employed borrowers, and the same short-window logic applies.

Frequently Asked Questions
How long is a mortgage quote good for?
There’s no universal answer, and I won’t invent one. A quote is non-binding information and can change when the lender reprices. Only a lock holds terms, and the lender should state its period and conditions in writing. In a market moving like this one, treat any quote more than a few days old as stale.
Should I wait for rates to come back down?
I can’t tell you they will. The September data shows four straight weekly increases in Freddie Mac’s survey and a 10-year Treasury at its highest since 2007. Sources disagree on what comes next. If the deal works at today’s cost of money, lock. If it doesn’t, no amount of waiting makes it a good deal.
Why does Freddie Mac’s number differ from what lenders quote me?
Freddie’s survey is a weekly average of conforming loans with 20% down and excellent credit, collected over the prior Thursday through Wednesday. Mortgage News Daily publishes a daily index of top-tier pricing. In the week of September 24, Freddie showed 7.03% while Mortgage News Daily’s index closed Thursday at 7.45%. Your own pricing depends on your profile, the property and the loan. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Do these averages apply to DSCR and bank statement loans?
Not directly. Freddie’s survey and the MBA’s series measure conventional, conforming loans, and I found no public non-lender dataset for investor or non-QM pricing. Use the headline numbers for direction. For actual terms, compare current quotes, subject to lender guidelines.
How many lenders should I talk to?
A handful of reputable ones is enough. More quotes rarely beat the cost of a longer window, since each day adds drift. Using a broker who compares many lenders at once is another way to shorten the process without narrowing the field.
