September 2026 Market Update: Rates Broke 7%, Boulder Prices Went Negative, and Buyers Are Still Sitting on Their Hands

The Galvis Group  |  Smart Strategy. No Hype.  |  August 2026 MLS data, published September 24, 2026

August was the month two trends that have been building all summer finally crossed a line. The 30-year fixed broke through 7% for the first time in a year. And the Boulder median sale price posted its first negative year-over-year reading since this cycle began.

Those two things are connected, and they add up to the same conclusion from different directions: this is a genuinely good time to buy, and almost nobody's acting on it. That's the headline across both the Denver housing market and the Boulder housing market this month.

Here's the part that matters more than any single number above. Sellers who need to sell are already adjusting, paying for rate buydowns and cutting price to get deals done. Buyers mostly aren't showing up to take advantage of it. That gap, more than any one statistic, is where the opportunity is right now.

1. The Numbers at a Glance

August 2026 data, compared to August 2025.

The two lines that matter most: Under Contract fell by double digits in both metros again, and it fell harder in Boulder, down 24.6%, than at any point this year. New Listings flipped negative in Boulder for the first time this cycle, down 5.3%, while Denver's kept climbing, up 10.7%. Two different supply stories, the same demand story underneath both: buyers pulled back everywhere.

2. Reading the Market: The Split Gets Wider

Boulder: the scarcity story just flipped

For most of this cycle, Boulder's pitch has been simple: tight supply, resilient prices. August broke that pattern. The median sale price fell to $850,000, down 2.3% from a year ago, Boulder's first negative year-over-year reading of this entire cycle. And it's not a one-month blip. The median has fallen for three straight months: $898,000 in June, $882,000 in July, $850,000 in August.

Meanwhile, inventory kept shrinking too. Homes for sale are down 5.2%, and new listings, which had been rising all summer, flipped to a 5.3% decline. Less coming on, less selling, and now, for the first time, prices actually giving ground. That combination only happens one way: demand pulled back faster than supply did.

The 49-day median time on market, down 16.9% from a year ago, looks like it contradicts that story. It doesn't. In Boulder, days on market runs to closing, not to contract, so that number only describes homes that actually sold, and the homes selling right now are disproportionately the well-prepared, correctly priced ones moving fast. Everything else just isn't closing at all, which is exactly why Under Contract activity fell 24.6%, the steepest drop of the year.

Denver: more supply, less demand, decelerating prices

Denver's headline gain is still positive, up 1.7% to $595,000, but that's a sharp deceleration from 6.1% growth just one month ago. And the setup behind it is getting less favorable by the month. Homes for sale are up 9.8%, new listings are up 10.7%, and both numbers are accelerating, not slowing down. Meanwhile Under Contract fell 10.4% and Closed Sales fell 15.6%.

More supply arriving faster, less of it getting absorbed. That's the mechanical definition of a market handing leverage to buyers, and Denver is handing over more of it every month.

The absorption math

For every 10 homes that came on the market in Boulder in August, roughly 6 went under contract. In Denver, it was roughly 5.8. Both numbers sit below where a balanced market would put them, and Boulder's months of supply held flat at 4.1 while Denver's climbed another 15.8% to 4.4. Both metros are now solidly in buyer-favorable territory, and Boulder just proved that even genuine scarcity isn't enough to keep prices moving up when buyers stop showing up.

3. Mortgage Rates: The 7% Line Just Got Crossed

August itself was calm on rates. After July's spike to a one-year high near 6.8%, the 30-year fixed spent most of August rangebound in the mid-6% range, giving buyers a bit of room to breathe, and it's a real part of why the homes that did close in August still moved at solid pricing.

Then September happened. Rates climbed steadily through the first half of the month, and on September 17 the Federal Reserve raised its policy rate a quarter point, its first hike since 2023, in direct response to inflation that's still running hot (August's CPI came in at 3.4% year over year, well above target). The 30-year fixed crossed 7% for the first time in a year, and weekly averages now sit at roughly 7.0% to 7.1%, depending on the tracker.

Here's the historical parallel worth sitting with. The last time rates did something like this, October 2023, the 30-year fixed broke 8% for the first time since 2000. Buyers who transacted anyway, while everyone else waited on the sidelines, got real leverage: less competition, more concessions, sellers who'd actually negotiate. Rates came down from there (2024 averaged 6.90%, 2025 averaged 6.66%, and 2026 had dipped as low as 6.01% in February) but home prices didn't fall to compensate. The buyers who moved during the scary headlines built equity while everyone waiting for "better rates" watched prices hold or climb.

We're watching the same setup happen in real time, in our own data. As rates climbed toward July's spike and now September's, Boulder's year-over-year price growth went from positive to negative in a single month. That's not a coincidence. It's the same mechanism working exactly the way it's supposed to: higher rates, fewer competing buyers, softer prices. The buyers who act while that's true are the ones who benefit from it.

4. What the Data Does Not Show: Notes From the Field

The MLS reports outcomes. It doesn't report what it took to get them, and this month, what it took was patience, on both sides.

It's been a genuinely quiet month out there. Showing activity is down, and even in some of the highest-demand neighborhoods, the share of listings actually making it to a sale is lower than I've seen it in this cycle. In the pockets I track closely, it's measurable: the share of listings that make it all the way to a sale has fallen from 100% of everything listed in 2023 down to 67.65% in the first quarter of this year, the last fully-resolved quarter I can measure cleanly. The two quarters since are trending lower still, but they're only partway resolved, so I won't call a final number on those yet. What's telling is that the ones that DO sell are still closing at 97% to 101% of list price. This isn't a price collapse. It's a much bigger share of listings never making it to a sale at all. Preparation matters more right now than at any point I can remember. A listing that isn't priced and presented correctly on day one isn't just sitting, it's disappearing into a pool of inventory nobody's paying attention to.

My duplex listing at 1434 12th Avenue in Longmont is a good example. I flagged it last month at a 6.4% cap rate with strong, stable tenants on both sides, the kind of numbers that used to move in days. We just dropped the price. On paper, it's a screaming deal. We had one showing. That's not a pricing problem anymore. That's investors sitting on their hands in a market that's practically begging them to act.

That's the pattern I'd point to across the board right now. Sellers who genuinely need to sell are doing whatever it takes: price cuts, seller-paid rate buydowns, credits. Nationally, seller concessions showed up in 44.7% of August home sales, the highest August share on record. That's sellers meeting the market. Buyers, by and large, aren't meeting them there yet. I've got a number of new listings coming online in October, and the ones that launch correctly from day one are going to be the ones that prove that out.

5. What This Means for Buyers

The trade everybody's missing

Here's the pattern worth understanding before anything else: home prices move opposite to buyer competition, not opposite to rates. When rates are high and everyone else is scared off, sellers negotiate. When rates drop and buyers flood back in, competition returns, and so does upward pressure on price. You can see it happening in this very report. As rates pushed toward 7%, Boulder's prices went negative for the first time this cycle. That's not bad news for buyers. That's the window.

The same thing happened after October 2023, when rates broke 8% for the first time in over two decades. Buyers who transacted anyway got real concessions and locked in a price before the competition came back. Rates eased over the following two years. Prices didn't fall to compensate. The people who bought into the scary headlines built the equity. The people waiting for "better rates" are still waiting.

Boulder Buyers

You're looking at the most negotiating room Boulder has offered in this entire cycle. Prices are down for the first time, under-contract activity fell 24.6%, and sellers are adjusting. The catch is the same as always: the well-prepared, correctly priced homes in strong locations are still moving fast (that's what the 49-day closing number is actually telling you), so know which kind of house you're looking at before you decide how hard to push. Search active Boulder listings here.

Denver Buyers

Denver is handing you more selection every month, up 9.8% in active inventory and 10.7% in new listings, while under-contract activity keeps falling. Price growth has slowed from 6.1% to 1.7% in a single month. If that deceleration continues, and the setup says it will, Denver could be looking at its own negative reading soon. Getting ahead of that, rather than reacting to it, is the advantage right now.

Both Metros

Ask for what you actually need on inspection, sellers are saying yes to more than they have in years. Ask what the seller will do on a rate buydown before you assume you're stuck with today's rate, 44.7% of sellers nationally are already offering some form of concession, and that number is climbing. And don't wait for the "right" rate. The right rate is the one that gets you a deal nobody else is competing for.

What a 2-1 buydown actually looks like

Here's the math, using a representative 7.00% note rate and 20% down (principal and interest only). On a Boulder-median home at $850,000, that's a $680,000 loan. Year one, at a 5.00% effective rate, the payment runs about $3,650 a month. Year two, at 6.00%, it moves to about $4,077. Year three onward, back at the full 7.00% note rate, it's about $4,524. That's roughly $15,800 in payment relief over the first two years, paid for by the seller, not the buyer.

On a Denver-median home at $595,000, that's a $476,000 loan. Year one runs about $2,555 a month, year two about $2,854, and year three onward about $3,167 at the full note rate. That's roughly $11,100 in relief over the same two years.

Here's the part worth sitting with. By the time year three arrives and the full note rate kicks in, history says the odds favor the buyer. The last time the 30-year sat above 7%, in 2023, it eased to a 2024 average of 6.90%, a 2025 average of 6.66%, and as low as 6.01% in February of this year. Nobody can promise where rates land two years from now, but the historical pattern strongly favors buyers getting a shot to refinance out of the full note rate long before they're stuck paying it for the life of the loan. The buydown buys time. Time has historically been on the buyer's side.

Investors

This is a genuinely good setup for rental purchases right now, and almost nobody's acting on it. Fewer buyers in the market for a primary residence generally supports rental demand, even while the purchase side stays quiet. My duplex at 1434 12th in Longmont, a 6.4% cap rate, just repriced, is exactly the kind of number that should be moving right now and isn't. If you've been waiting for a better entry point on an income property, this is what one looks like.

6. What This Means for Sellers

Boulder Sellers

The scarcity that's protected Boulder pricing all year just stopped being enough on its own. Three straight months of sequential price declines, and August's first negative year-over-year reading, mean the market isn't going to bail out an aspirational list price anymore. Sold price came in at 96.2% of original list, which puts the typical Boulder seller a couple of points behind their original ask. Correct pricing on day one is no longer a nice-to-have. It's the one lever that still reliably works.

Denver Sellers

Denver's inventory grew 9.8% and new listings grew 10.7%, while under-contract activity fell 10.4%. That's more competition for your listing and fewer buyers to go around. The homes closing are still closing at 96.2% of original list and in 32 days, so demand hasn't disappeared, it's just gotten more selective about where it shows up. Your first two weekends are still the whole negotiation.

Both Metros

If you don't need to sell right now, that's a legitimate answer, wait for rates to ease and buyer competition to return. If you do need to sell, meet the market where it is. That increasingly means a rate buydown or a closing cost credit alongside your price, not instead of it. Nationally, sellers are already doing this in 44.7% of transactions. Budget for it before you launch, not after your first weekend goes quiet. Curious what your equity looks like in this market? Run a free valuation here.

7. The 30-Day Projection

Rates: Expect the 30-year fixed to hold in the low 7s, likely 6.9% to 7.3%, through the next month. The Fed just hiked, inflation is still running above target, and there's no near-term catalyst pointing the other direction. Any dip back toward 6.7% to 6.8% is a lock opportunity, not the start of a new trend.

Closed sales: August's under-contract collapse, down 24.6% in Boulder and 10.4% in Denver, is next month's closing data. Expect October and November's closed-sales numbers to come in weak in both metros. That's the September rate spike working through the pipeline, not a new collapse in demand.

Inventory: Denver should keep adding supply through early fall before the seasonal slowdown arrives in November. Boulder's inventory should stay roughly flat, with new listings likely staying soft as sellers who don't need to sell right now choose to wait.

Prices: Expect Boulder's year-over-year comparisons to stay negative for at least another month or two, with Denver's continuing to decelerate. Nothing here points to a price crash. It points to a genuine, and probably brief, cooling.

The wildcard: How buyers respond to a 7% headline. Historically, the scariest rate headlines are exactly when the best deals get made, because that's when the competition disappears. The buyers who understand that will do very well over the next six to twelve months. The ones waiting for the headline to improve will be competing with a lot more people when it finally does.

8. About The Galvis Group

I'm Stu Galvis, a fourth-generation broker in my 22nd year in the business. I've closed more than 750 transactions from Boulder to Denver, and I've spent close to two decades training and coaching other brokers, locally, regionally, and nationally. That's a long way of saying I've spent a lot of time studying what actually causes homes to sell in the Denver real estate market and the Boulder real estate market, and what doesn't.

This report exists because most market commentary is either a cheerleading exercise or a scare tactic, and neither one helps you make a decision. The numbers are the numbers. What matters is what you do with them.

If you're weighing a move in the next 6 to 12 months, in either direction, the current market rewards the buyers and sellers who act on what the data actually says over the ones reacting to the headline. I'm happy to run your specific numbers with you, no expectation attached. Schedule a conversation here.
