Home Prices Rose 2.1%, but Fell After Inflation for 15 Months
Your home's price tag went up, but its buying power went down. The latest Case-Shiller report, explained without the jargon.

- The headline: U.S. home prices rose 2.1% in the year to August 2026, per the S&P Cotality Case-Shiller National Index (released October 27).
- The catch: Inflation ran at 3.4%, so after adjusting for inflation, home values fell for the 15th month in a row.
- Hot spots: Chicago (+6.7%), New York (+6.2%) and Cleveland (+4.3%) led.
- Cooling spots: Seattle (-2.0%), Las Vegas (-1.3%), Denver and Dallas (-0.8% each) and Tampa (-0.4%) were down from a year ago.
Your home’s price tag went up. Your home’s buying power went down. Both are true at once, and the latest Case-Shiller report shows exactly how.
Here’s the plain-English version of the most-watched home price index in America, and what it means if you own, are buying, or are waiting.
What the August report found
S&P Dow Jones Indices released its August 2026 Case-Shiller results on October 27. The national index was up 2.1% from August 2025, a bit faster than July’s 1.9%. The big-city composites rose faster than the nation as a whole.
| Index | Annual change (Aug 2026) | July 2026 |
|---|---|---|
| National | +2.1% | +1.9% |
| 10-City Composite | +3.6% | +3.4% |
| 20-City Composite | +2.7% | +2.5% |
Month to month, prices dipped 0.2% before seasonal adjustment, which is normal as the summer buying season winds down. After adjusting for the season, the national index rose 0.3%.
“Up 2.1%” but “down in real terms”? Both are right
Case-Shiller tracks nominal prices, the actual dollar amounts homes sell for. Inflation tells you how much those dollars can buy. In August, consumer prices rose 3.4% from a year earlier, about 1.3 points faster than home prices. S&P noted this was the 15th straight month that home values fell after inflation.
Say your home was worth $400,000 in August 2025.
- A 2.1% gain makes it about $408,400 on paper.
- But with 3.4% inflation, that $408,400 buys what about $395,000 bought a year ago.
So in “real” terms, the house lost a little over 1% of its value, even though the number went up.
Where prices are rising and falling
The gap between metros is wide. Midwest and Northeast markets keep gaining, while several pandemic-era boomtowns in the South and West are slipping.
| Strongest (year over year) | Change | Weakest (year over year) | Change |
|---|---|---|---|
| Chicago | +6.7% | Seattle | -2.0% |
| New York | +6.2% | Las Vegas | -1.3% |
| Cleveland | +4.3% | Denver | -0.8% |
| Dallas | -0.8% | ||
| Tampa | -0.4% |
Detroit had no valid August number because of delays in recording sales data, so it’s missing from this month’s ranking.
Why prices aren’t falling despite 7% rates
High rates usually cool prices. So why are they still edging up? Mostly because supply is tight in many areas. Many owners have older, cheaper mortgages and don’t want to give them up, and builders started fewer homes in September than in August, according to the Census Bureau. Fewer homes for sale keeps a floor under prices even when fewer people are buying.
Keep in mind that Case-Shiller is a three-month moving average with a two-month delay. August data mostly reflects deals signed in early summer, before rates jumped above 7% in late September.
What this means for you
- Buyers: In the cooling metros, you may find sellers open to price cuts or credits. In the hot ones, don’t expect bargains. Check your budget with the home affordability calculator.
- Owners: Slower price growth means your equity grows mostly by paying down the loan. Our extra payment calculator shows how small extra payments speed that up. If you put less than 20% down, rising equity may also help you get rid of PMI.
- Renters on the fence: With prices flat-ish and rates high, renting a while longer can make sense in some cities. Compare both paths with the rent vs. buy calculator.
The next Case-Shiller report, covering September, is scheduled for the last Tuesday of November.
FAQ
How much did U.S. home prices rise in August 2026?
The S&P Cotality Case-Shiller National Index rose 2.1% from a year earlier. The 20-City Composite rose 2.7% and the 10-City Composite rose 3.6%.
What does “home prices fell in real terms” mean?
It means prices rose more slowly than overall inflation. In August, inflation was 3.4% while home prices rose 2.1%, so a home’s value bought less than it did a year ago.
Which cities have falling home prices?
In the August report, Seattle, Las Vegas, Denver, Dallas and Tampa were below their year-earlier levels.
Will home prices drop in 2027?
No one knows for sure. Prices depend on rates, jobs and how many homes come up for sale. Most official forecasts expect slow growth or flat prices rather than a crash, but local markets can differ a lot.
