Where Mortgage Rates Stand the Week of September 24, 2026

Mortgage rates rising in September

Freddie Mac’s Primary Mortgage Market Survey, released September 24, put the 30-year fixed-rate mortgage at 7.03 percent, up from 6.95 percent the week before. The 15-year fixed moved to 6.42 percent from 6.26 percent. A year ago the same survey had the 30-year at 6.30 percent, so rates are roughly seven tenths of a point higher than they were last September.

Sam Khater, Freddie Mac’s chief economist, said the housing market is still supported by a solid labor market and an economy growing at a healthy pace. That is the honest read. Crossing 7 percent makes a headline, but this is movement, not a trend you should reorganize your life around. Here is what it actually means if you are buying or selling a home in the Chicago suburbs this fall.

What an Eight Basis Point Week Costs a Real Buyer

Percentages are abstract. Payments are not. So let me put real arithmetic on it.

Take a $400,000 loan on a 30-year fixed. At last week’s 6.95 percent, principal and interest run about $2,648 a month. At this week’s 7.03 percent, the same loan runs about $2,669. That is roughly $21 a month, or about $258 a year.

Now compare it to last September, when the survey had the 30-year at 6.30 percent. That same $400,000 loan would have been about $2,476 a month. Against today, that is roughly $193 more per month, or about $2,320 a year.

Two things to keep straight. These figures are principal and interest only. In DuPage, Will, Kane and Kendall counties, property taxes and insurance add a substantial amount on top, and in this market that escrow line is often the larger surprise. And the survey is a national average. Your actual quote depends on your credit, your down payment, the loan type and the lender, and the spread between the best and worst quote a buyer receives in the same week is frequently wider than the entire move I just described.

That last point is the practical one. If a $21 monthly difference matters to your budget, shopping three lenders is worth far more of your attention than watching the weekly survey.

Why This Fall Feels Different Than Last Fall

Buyers who started looking last year and stepped away are coming back to a different payment on the same house. That is the real story in the number, and it is why some of the people who paused in the spring are now moving.

What I see consistently across the western suburbs is that well-prepared homes in the most sought-after locations still draw strong activity regardless of where the survey lands in a given week. Homes that are priced on last year’s optimism sit. That gap between the two has widened as rates have moved up, because buyers paying more per month have less patience for a house that needs work or a seller who will not negotiate.

I spent four years as a Branch Executive for Berkshire Hathaway HomeServices, watching how agents and clients across an entire office responded to rate moves. The pattern held then and it holds now. The buyers who do well are the ones who stay ready and act when the right house appears. The ones who try to time the weekly survey usually end up buying later, at a higher price, at a rate that was not much different anyway.

What to Do If You Are Buying This Fall

Get your pre-approval refreshed. A letter written at a 6.2 percent assumption does not reflect what you qualify for today, and finding that out while you are writing an offer is the worst possible timing.

Ask your lender specifically about a rate lock with a float-down option, and about temporary buydowns. In a market where sellers have less competition than they did two years ago, a seller-paid buydown is often easier to negotiate than a price reduction of equivalent value, and it hits your monthly payment harder. That is a conversation to have before your offer is written, not after.

And do not let the rate decide the house. Rates can be refinanced. A location cannot. The families I have watched regret a purchase almost never regret the rate they paid. They regret the commute, the school boundary, or the lot they talked themselves into.

What to Do If You Are Selling This Fall

Price against what is selling right now, not against what your neighbor got in 2022. Every increase in rates narrows the pool of buyers who can reach your price, and the correction for an overpriced listing is paid in time on market, which costs more than the reduction would have.

Fall is a real selling season in this market, not a consolation prize. The buyers looking in October and November are generally motivated, often working against a relocation timeline or a school-year deadline. There are fewer of them and fewer competing listings, which is not a bad trade for a well-prepared home.

Get the condition right before you list. Buyers absorbing a higher payment have very little appetite for deferred maintenance, and they discount for it far more aggressively than the repair would have cost. My home selling resources cover what is worth doing and what is not, and it is worth reviewing recent sold listings in your area to see what the market has actually been paying.

What I Would Not Do Right Now

I would not wait for a number. Buyers have been waiting on a rate for three years, and the ones who waited are looking at higher prices on top of the rate they were trying to avoid. Nobody rings a bell.

I would not assume a rate move changes your neighborhood. National averages are national. What a house in Naperville or Wheaton does depends far more on its street, its school assignment, its condition and its price than on an eight basis point week.

And I would not make a decision from a headline. Ask what it does to your payment on the house you actually want. That is a five-minute conversation with a lender, and it turns an abstract worry into a number you can decide on.

Key Takeaways

  • Freddie Mac’s September 24 survey put the 30-year fixed at 7.03 percent and the 15-year at 6.42 percent. Both are up from the prior week and meaningfully above where they sat a year ago.
  • On a $400,000 loan, the week-over-week move is about $21 a month in principal and interest. The year-over-year difference is closer to $193 a month.
  • Those are national averages, not your quote. The spread between lenders in any given week is often wider than the move itself, so shopping lenders is the highest-value thing a buyer can do right now.
  • For sellers, higher rates mean a smaller qualified buyer pool and less tolerance for deferred maintenance or aspirational pricing. Condition and a defensible price matter more this fall than they did two years ago.
  • For buyers, get the pre-approval refreshed, ask about buydowns and float-down locks, and choose the house on its location and condition rather than on the week’s rate.
