Market Insight · September 2026
Sellers now outnumber buyers by a record margin. Mortgage rates just hit a 15-month high. Here is how those two facts fit together, and what they mean if you are deciding whether to move.

If you have been watching the market and waiting for a clear signal, this month delivered two of them, and they point in opposite directions.
On one side is the deepest buyer's market in modern record-keeping, with more homes for sale than at any point since early 2020. On the other is the highest mortgage rate in 15 months and a Federal Reserve that appears ready to raise, not lower, its benchmark rate this week.
Understanding how those two forces interact is the difference between a well-timed move and an expensive one. Here is what the data says, where it comes from, and how I am advising clients to think about it.
01Sellers outnumber buyers by a record margin
Redfin's September 10 analysis estimates there were 57.9% more home sellers than buyers nationally in August, the widest gap since the firm began tracking the figure. Roughly 1.53 million sellers were in the market, the most since the start of 2020.
The Denver metro is running wider than the national number. Redfin estimates 64.6% more sellers than buyers here in August, roughly 16,500 sellers against 10,000 active buyers.
That is leverage for buyers. It is also a reminder for sellers that a listing has to compete on preparation, positioning, and price from day one. A home that launches unprepared is now competing against nearly two listings for every buyer.
02Prices are holding. Activity is not.
The Denver Metro Association of Realtors' August report, covering all residential property types across the 11-county metro, shows a market cooling in volume rather than in value:
- Median closed price: $594,495, essentially flat year over year and down 1.74% from July.
- Closed sales: down 17.35% year over year and down 18.99% from July.
- Active listings at month end: 13,080, a fraction higher (0.16%) than August 2025.
- Average days in MLS: 27, up from 21 in July but still faster than the 30 days recorded a year ago.
In the $1 million-plus segment, detached homes accounted for 95.6% of sales. Detached luxury homes averaged 47 days in MLS, about 8% faster than a year ago, while attached luxury properties took 99 days, roughly double last year's pace. DMAR's own characterization is worth repeating: this is neither clearly a buyer's nor a seller's market. Luxury buyers are still transacting, but they are discerning, and every property is judged on its own circumstances.
Realtor.com's August data tells the same story from the listing side. Denver active listings were up 2.1% year over year, the median list price was $574,900, median days on market was 59, and 31.4% of Denver listings carried a price reduction, well above the 20.4% national share.
03Nationally, the seasonal cool-down arrived early
Realtor.com's national August report shows active inventory up 3.6% year over year, a median list price of $424,500 (down 1.3%), price per square foot down 1.8%, and median days on market at 60. One in five listings nationally had taken a price cut. The firm's chief economist described a market "entering its seasonal cool-down with less momentum than it had earlier this year."
04Financing is the obstacle, and it just got heavier
This is the part that keeps a buyer's market from feeling like one.
- Freddie Mac's 30-year fixed averaged 6.76% for the week of September 10, up from 6.71% the prior week and 6.35% a year ago. That is a 15-month high. The 15-year fixed averaged 6.09%.
- The move follows a jump in Treasury yields, with the 10-year breaching 4.9%, driven by inflation data and an oil-price shock. U.S. crude topped $100 a barrel on September 10 amid escalating conflict in the Middle East.
- August CPI, released September 11, rose 0.4% for the month and 3.4% year over year. Core inflation rose 0.3% monthly and 2.4% annually. Gasoline alone accounted for more than a third of the monthly increase, and shelter costs rose 0.3%.
Those inflation numbers matter for one reason: they make it harder for the Fed to lower rates and easier to justify raising them.
05This week: the Fed decides
The Federal Open Market Committee meets September 15 and 16. As of September 9, CME FedWatch showed futures markets pricing an 85% probability of a quarter-point increase, and that figure has only firmed since the CPI release.
Two cautions. First, the Fed does not set mortgage rates. Mortgage rates track long-term Treasury yields, which move on expectations, so much of a September hike is already reflected in today's 6.76%. Second, what the Fed says about future moves will likely matter more for mortgage rates than the decision itself. A single hike with a signal of restraint could ease yields. A hike with language about more to come could push them higher.
06The cost buyers underestimate: insurance
ICE's September Mortgage Monitor reports the average homeowners insurance premium on a mortgaged home reached $209 per month, up 8.7% year over year, and now accounts for 9.6% of the typical monthly mortgage payment. The one piece of good news in that report is that the pace of increase is finally slowing.
For anyone shopping in Colorado's foothills, acreage, and wildland-interface areas, insurance is not a line item to estimate at the end of the process. It belongs in the first conversation.
If you are buying
Negotiating power is real, but it lives in the terms, not only the price. In a market with 64.6% more sellers than buyers, these are the questions worth asking:
- What is the whole monthly payment? Principal and interest, property taxes, insurance, HOA or metro-district fees. A lower price on a home with a high metro-district mill levy can cost more per month than a higher-priced home without one.
- Can a seller concession do more work than a price cut? A credit applied to a temporary or permanent rate buydown often lowers the monthly payment more than the equivalent dollar reduction in price.
- Will the property hold value if rates stay here? With 31% of Denver listings already reduced, discipline on condition, location, and lot quality matters more than it did two years ago.
If you are selling
Prices are holding, but only for homes that are prepared, priced to the current comparable set rather than last spring's, and marketed with precision from launch. Average days in MLS are still under a month, which tells you the well-positioned listings are moving. The ones that are not moving are the ones accumulating price reductions.
The right work in the right order still wins. It simply has less margin for error.
A note on timing
Waiting for a clear signal usually means waiting for the moment everyone else sees it too. The current combination of abundant inventory, softening asking prices, and financing costs that are keeping many buyers on the sidelines is precisely the environment in which a prepared buyer with a well-structured offer has the most room to negotiate. When rates eventually ease, that room narrows.
