If you only read the headline, the 2026 housing market looks almost boring. National single-family home prices rose about 1.8% over the year through August, according to Cotality's latest Home Price Index — the fifth straight month that annual growth nudged higher. Modest, steady, forgettable. But that one number is an average stretched across 50 very different markets, and in 2026 the stretch is extreme. Behind the calm national figure sits a 7.5-percentage-point gap between the fastest-rising state (Illinois, +6.8%) and the weakest (Texas, -0.7%). Prices are climbing at a healthy clip across much of the Midwest and Northeast while they quietly erode across parts of the Sunbelt and West. If you're trying to decide whether to buy, sell, or sit tight, the national average is close to useless. What matters is the market you're actually standing in — so here's how to read it.
One national number, two very different markets
Cotality pegs year-over-year price growth at roughly 1.8% through August 2026, up from 1.6% in July. On a month-to-month basis, though, prices actually slipped 0.1% in August — against a pre-pandemic August norm of a 0.3% gain — and the firm projects outright monthly declines through the winter, with full-year 2026 appreciation landing near 1.3%.
So the 'reacceleration' in the annual figure is partly a trick of the calendar, comparing today against a soft patch a year ago. The forward-looking signal is cooling. But 'cooling' is itself a national abstraction. Zoom into the state level and you find two housing markets wearing one label.
On one side: supply-starved, relatively affordable states where prices are still rising 5-7% a year. On the other: formerly red-hot Sunbelt and Western markets where prices have flatlined or turned negative after years of outsized gains. The gap between them is now wider than the national growth rate itself.
The 2026 price map, by the numbers
Here is the year-over-year single-family price change through August 2026 at the two ends of the spectrum, per Cotality's state-level data:
Leading the gains
- Illinois: +6.8%
- Connecticut: +6.3%
- Indiana: +5.6%
- New Jersey: +5.6%
- Ohio: +4.8%
Flat to falling
- Texas: -0.7%
- Hawaii: -0.7%
- Washington: -0.4%
- Colorado: +0.1% (essentially flat)
- Oregon: +0.3%
- Arizona: +0.5%
- Nevada: +0.7%
Why the Midwest and Northeast are winning right now
The common thread among the leaders is scarcity plus affordability. These are markets that never overbuilt during the pandemic boom, so inventory is tight — and they start from lower price bases, so buyers priced out of the coasts can still transact.
That scarcity is reinforced nationwide by the 'lock-in effect.' Roughly 60% of mortgage holders carry a rate below 4%, and with 30-year rates still hovering in the high-6s, most of them have no intention of selling and trading that rate away. Housing inventory nationally remains around 17% below pre-pandemic levels, and in the Midwest and Northeast that shortage is acute enough to keep bidding pressure alive even as transaction volume falls.
Cotality's chief economist has made the point directly: high mortgage rates are suppressing sales volumes across the board, but tight supply in the Midwest and Northeast is insulating prices in those regions from the slowdown. Fewer homes change hands, but the ones that do still clear at higher prices.
Why the Sunbelt and West cooled off
The laggards tell the opposite story. Texas, Arizona, Nevada, Colorado, and parts of the Pacific Northwest absorbed enormous price run-ups from 2020 to 2023 and, in many metros, a wave of new construction. That combination — stretched affordability plus rebuilt supply — is exactly what caps prices.
Layer on the carrying costs that have climbed fastest in these same regions: property-insurance premiums and property taxes have surged across much of the Sunbelt, quietly raising the true monthly cost of ownership even where sticker prices haven't moved. When the all-in cost rises but wages don't, demand softens and prices follow.
The result is a reversal of the pandemic playbook. The markets that led the boom are now leading the cooldown, and the 'boring' interior and Northeast markets that lagged are the ones holding their value.
Watch momentum, not just the year-over-year headline
A single annual number can be stale. Take San Francisco: it still shows a strong +7.0% year-over-year gain, but its three-month momentum has turned negative at -2.7% — meaning the market cooled sharply in the most recent quarter even though the trailing-year figure still looks hot. When you research your area, pull the latest one- to three-month trend from a source like Realtor.com, Redfin, or Zillow alongside the annual figure. The recent direction often tells you more about where your negotiating leverage is heading than the year-over-year print does.
There's also a split inside your own neighborhood
Geography isn't the only divide. Property type matters too. Nationally, single-family detached homes rose about 2.1% over the year, while attached homes — condos and townhomes — were essentially flat at +0.1%. Rising HOA dues and insurance assessments have made condos a tougher sell in many markets, so even within one zip code, a detached house and a condo can be on opposite trajectories.
The practical takeaway: a 'the market is up 2%' statement is almost never specific enough to plan around. Up where? Which property type? Over what window? Those three questions change the answer dramatically.
What this means if you're buying
Match your strategy to your local regime. In a leader market (much of the Midwest and Northeast), you're still closer to a seller's market: expect competition on well-priced homes, come in with a clean offer, and don't assume you can lowball. Scarcity, not momentum, is holding prices up there.
In a laggard market (much of the Sunbelt and West), you have more room than you've had in years. Days-on-market are longer, price cuts are more common, and seller concessions — rate buydowns, closing-cost credits — are back on the table. Use them. The bigger question in those markets isn't 'will I overpay?' but 'does buying beat renting at all right now, given my timeline and the local cost of ownership?'
What this means if you're selling
Price to your actual micro-market, not to the national narrative or to last spring's comps. With national inventory at roughly 4.9 months of supply earlier this year — the highest in more than a decade — and winter price declines projected, the homes that sell are the ones priced correctly on day one. In cooling markets, the first two weeks of listing are your strongest leverage; a stale listing invites exactly the lowball offers you're trying to avoid.
If you're a leader-market seller, you still have the upper hand, but buyer budgets are capped by high rates — so pricing a hair under the top comp often draws more competition and a better final number than reaching for an aspirational figure and chasing the market down with cuts.
The single most useful thing you can do in a market this fragmented is stop reasoning from the national average and start reasoning from your own numbers. Whether you're weighing an offer in a hot Midwest metro or deciding if it's even worth buying in a cooling Sunbelt suburb, the decision ultimately comes down to one comparison: what does owning cost you per month, all in, versus renting the same home — and how long do you plan to stay? Run your local prices, rents, rate, taxes, and insurance through LoanPal's Rent vs. Buy Calculator to see where the math actually tips in your favor. In 2026, that break-even point is landing in wildly different places depending on which of the two housing markets you happen to live in.
