For most of this year, mortgage rates moved sideways in the mid-6% range. September broke that pattern. The Federal Reserve raised its benchmark rate, and the 30-year fixed average crossed 7% for the first time in a long while. Here is what happened, and what I would do with it if I were buying or refinancing in Colorado this fall.
Key takeaways
- The Fed raised the federal funds range to 3.75%–4.00% on September 16. The vote was 12-0.
- Freddie Mac's 30-year average rose every week in September, from 6.71% to 7.03%.
- Fed officials' median projection points to a 4.1% federal funds rate at the end of 2026. That implies one more increase this year.
- On a $500,000 loan, the move from 6.66% in late August to 7.03% adds about $124 a month in principal and interest.
- Seller concessions and ARMs are the main tools for managing the payment right now. Waiting for a drop is not a plan.
What the Fed did
The Federal Open Market Committee's September 16 statement raised the target range by a quarter point, to 3.75%–4.00%. The statement said economic activity "is expanding at a solid pace" and that "inflation remains elevated." Fox Business reported that it was the first hike since July 2023, after the Fed held rates steady at its first five meetings of the year.
Fed Chair Kevin Warsh framed it as a response to a strong economy. "Our decision comes at a time when the American economy appears to be strengthening," he said at his press conference.
The forward guidance matters more than the quarter point. In the September Summary of Economic Projections, the median official expects:
- A federal funds rate of 4.1% at the end of 2026 and 2027, then 3.9% in 2028 and 3.6% in 2029. In June the 2026 projection was 3.8%.
- PCE inflation of 3.7% this year, up from 3.6% in June. Core PCE is projected at 3.4%.
- Inflation of 2.0% is not projected until 2029.
Put simply, Fed officials no longer expect cuts in 2027. That is the part bond markets reacted to.
What mortgage rates did
Mortgage rates do not follow the Fed's rate one for one. They tend to follow longer-term Treasury yields, and those had already been rising. At the press conference, the 10-year Treasury yield was around 5%, the highest since 2023, according to Fox Business. Here is how Freddie Mac's weekly survey moved through September:
| Week of | 30-year fixed | 15-year fixed |
|---|---|---|
| Sept. 3 | 6.71% | 6.04% |
| Sept. 10 | 6.76% | 6.09% |
| Sept. 17 | 6.95% | 6.26% |
| Sept. 24 | 7.03% | 6.42% |
A year ago the 30-year averaged 6.30%, so rates are now 73 basis points higher than last September. The Mortgage Bankers Association's survey, which measures contract rates on applications, was even higher. For the week ending September 18 it reported a 7.12% conforming 30-year rate. MBA's Mike Fratantoni called it "the highest level since May 2024," as HousingWire reported.
What it costs in real dollars
Headlines about 7% sound dramatic. The monthly math is more modest. On a $500,000 30-year loan, principal and interest works out to:
- About $3,213 a month at 6.66% (Freddie Mac's average in the last week of August)
- About $3,337 a month at 7.03%
That is roughly $124 a month more. It matters, but it is often smaller than what a buyer can win back through price and concessions in today's market. You can run your own numbers with our mortgage payment calculator. Taxes, insurance and HOA dues come on top of these figures.
Where Colorado buyers have leverage
Higher rates arrived at the same time Colorado's market was already shifting toward buyers. The Colorado Association of REALTORS® August report found that nearly 46% of Denver-metro closings involved a price reduction and 61% included seller concessions. That leverage is how you manage a 7% rate.
Use concessions for a rate buydown
A seller credit can pay for discount points or a temporary buydown instead of a price cut. On conventional loans, the credit is capped by your down payment: 3% with less than 10% down, 6% with 10%–25% down, and 9% with more than 25% down. On investment properties the cap is 2%. FHA allows up to 6%. The right mix depends on how long you plan to keep the loan.
Look at an ARM honestly
The MBA's 5/1 ARM average was 6.10% for the week ending September 18, and ARMs rose to 9.8% of applications. Conforming ARMs today are SOFR-indexed 5/6, 7/6 and 10/6 loans. The rate is fixed for the first period and then adjusts every six months within caps. That can make sense if you expect to sell or refinance within the fixed period. It is a poor fit if the payment only works at the starting rate. Our ARM loan page explains the structures.
Jumbo buyers: check the spread
In the same MBA survey, jumbo 30-year contract rates averaged 7.15%, very close to the conforming rate. Buyers in Vail, Aspen and Summit County should price both paths. Our Colorado jumbo loan guide covers the county limits.
If you already own
Many Colorado owners who bought or refinanced before 2022 have rates well below today's. For them, the hike changes little. If you took a loan in 2023 or 2024 above 7.5%, keep your refinance options on file. A refinance only makes sense when the savings cover the closing costs within a time frame you are comfortable with. Under the Fed's current projections, no one should count on a quick return to 6%.
What this means for you
I have financed Colorado homes for more than 30 years, through rate cycles much sharper than this one. The pattern that holds up is simple: set your budget at today's rate, not the rate you hope for. Then use the leverage this market gives buyers, such as price, concessions and loan structure, to get the payment where it needs to be. If rates fall later, refinancing is an option. If they don't, you already own a home you can afford.
Rates change daily, and your rate depends on your credit, down payment and property. The survey averages above are a starting point, not a quote. When you are ready to see your real numbers, start a pre-approval with Cedar Home Loans.
