The S&P Case-Shiller U.S. National Home Price Index posted a 1.1% annual gain for May 2026, up from a 0.9% rise in the previous month, according to data released yesterday by S&P Dow Jones Indices. But the headline number masks a more sobering reality: for the 12th consecutive month, U.S. home values fell in real terms, as May’s 4.2% inflation ran roughly 3 percentage points above the 1.1% home price gain.
After seasonal adjustment, the U.S. National index reported a monthly decrease of 0.05%, marking the third consecutive month with a month-over-month decline. For homeowners who bought at the peak in early 2026 or late 2025, the combination of flat nominal prices and rising costs means their real housing wealth has eroded significantly over the past year.
The data paints a picture of a housing market stuck in neutral—not crashing, but not building wealth either. With 30-year mortgage rates at 6.5% in May and inflation at its highest level in over three years, both buyers and sellers are caught in an affordability squeeze that shows no signs of easing.
The numbers
What the May data shows
Nominal gains, real losses, and a market divided by region
The S&P Case-Shiller U.S. National Home Price Index, which covers all nine U.S. census divisions, recorded a 1.1% annual increase in May 2026. The 10-City and 20-City Composites reported year-over-year increases of 2.4% and 1.6%, respectively. On the surface, these numbers suggest modest growth. But once you account for the cost of living, the story changes dramatically.
After adjusting for inflation, the monthly change fell to -0.3% and the annual change fell to -2.1% for the national index. That means a home worth $400,000 in May 2025 might be listed at $404,400 today—but in terms of what that money can actually buy, it’s worth less than it was a year ago.
The official data, published on S&P Global’s press release page, reveals sharp regional divides. A nearly 9 percentage-point gap separated May’s strongest market (Chicago +6.9% year-over-year) and its weakest (Las Vegas -1.9% year-over-year), underscoring how local conditions now matter more than national trends.

Monthly change (seasonally adjusted): -0.05% national, third straight decline
Inflation rate: 4.2% in May, highest in over three years
30-year mortgage rate: 6.5% in May
Regional winners and losers
Where prices are rising—and falling
The Midwest and Northeast gain ground while Sun Belt markets cool
The housing market’s regional split has never been starker. Chicago led annual gains for the third straight month (+6.9%), followed by New York (+4.2%) and Cleveland (+3.1%). These are cities that sat out much of the pandemic-era frenzy and are now seeing modest appreciation as buyers seek affordability.
On the other end, Las Vegas (-1.9%) posted the largest annual decline, with Seattle (-1.8%), Denver (-1.8%), and Tampa (-1.6%) also falling. Many of these markets saw explosive growth between 2020 and 2022, and builders flooded them with new inventory. The result: more homes for sale, longer days on market, and sellers adjusting their expectations downward.
For the nine census divisions, seasonally adjusted monthly home price changes ranged from -0.6% in the Pacific division to +1.4% in the East South Central division. The 12-month changes ranged from -0.3% in the Pacific division to +4.5% in the Middle Atlantic division. If you’re shopping for a home, your local market matters far more than any national headline.
The trend mirrors broader economic shifts. States with lower costs of living and more housing construction—particularly in the Midwest—are seeing renewed interest. Meanwhile, expensive coastal and Sun Belt markets that boomed during remote work are now dealing with oversupply and weakening demand. For buyers considering affordability strategies, this regional divergence creates real opportunities in cities that were previously overlooked.
The bigger picture
Why real prices are falling
High mortgage rates and stubborn inflation create a double squeeze
Rebecca Kaufman, Associate Director of Commodities at S&P Dow Jones Indices, summed up the challenge in the official release: “May’s data suggests that U.S. home prices continue to decline in real terms, with the S&P Case-Shiller National Home Price Index up a modest 1.1% year over year. At the same time, inflation peaked at 4.2% in May, its highest level in over three years”.
The math is straightforward but painful. If your home’s value rises 1.1% but the cost of groceries, gas, insurance, and everything else rises 4.2%, you’ve lost ground. Even on a nominal basis, the market remains noticeably weaker than a year ago. In May 2025, the National Home Price Index was up 2.4% year over year—more than double this year’s pace.
“Affordability remains a significant headwind for the housing market. Thirty-year mortgage rates increased to 6.5% in May, leaving the ultra-low 3% borrowing costs a distant memory. At the same time, stubbornly high inflation rates are keeping both the cost of home financing and the cost of living high for prospective buyers”, Kaufman noted.
“Against this backdrop, housing demand remains constrained, elevated borrowing costs continue to discourage potential homebuyers, and housing values decline in real terms for existing homeowners”. For first-time buyers already stretching to afford a down payment, the combination of high rates and falling real values makes the decision even harder. Our guide to mortgage options and rates can help you navigate the current environment.
The inflation gap
Home prices have now lagged inflation for 12 consecutive months. At the current pace, a homeowner who bought in May 2025 has seen their real housing wealth decline by roughly 2.1%, even as their nominal home value ticked up slightly. For a $400,000 home, that’s an $8,400 loss in purchasing power over one year.
What to do
How buyers and owners should respond
Practical steps in a market that’s neither booming nor crashing
If you’re waiting for a dramatic price crash, the data suggests you’ll be waiting a long time. While real values are falling, nominal prices remain positive in most markets. The Case-Shiller Index measures a three-month rolling average of closed sales, so May includes sales from March to May and contracts from as early as January. The market you see today reflects decisions made months ago.
For buyers: Focus on your local market, not national headlines. If you’re looking in Chicago, Cleveland, or other Midwest cities, you may find more competition as prices rise. If you’re shopping in Las Vegas, Denver, or Tampa, you have more negotiating power than you did a year ago. Check whether your state offers down payment assistance or first-time buyer programs that can offset high borrowing costs.
For current homeowners: If you bought within the past year, your home’s nominal value has likely held steady or risen slightly, but your real equity has declined. Don’t panic—this is a function of inflation, not a housing crash. If you’re considering selling, be realistic about pricing. The gap between the non-seasonally adjusted and seasonally adjusted results underscores the extent to which seasonal factors are supporting headline price growth. Even where prices increased on a seasonally adjusted basis, gains remained modest and were negative in real terms.
For those on the fence: The decision to buy a home should be based on your financial readiness, not market timing. If you have a stable income, a solid down payment, and plan to stay in the home for at least five years, buying now can still make sense—especially if you lock in a fixed-rate mortgage before rates climb further. Our home buying timeline guide walks through each step of the process.

Quick answers
Case-Shiller Index: common questions
Are home prices actually falling?
It depends how you measure. In nominal terms, the national index is up 1.1% year-over-year. But after adjusting for inflation (4.2% in May), real home values have fallen 2.1% annually for 12 straight months. On a seasonally adjusted month-over-month basis, prices declined for the third consecutive month.
Which cities are seeing the biggest price drops?
Las Vegas led declines at -1.9% year-over-year, followed by Seattle and Denver (both -1.8%), and Tampa (-1.6%). Many of these markets saw rapid appreciation during the pandemic and now face increased inventory from new construction.
Which cities are still seeing price growth?
Chicago led all major metros with a +6.9% annual gain, followed by New York (+4.2%) and Cleveland (+3.1%). Midwest and Northeast cities that sat out the pandemic boom are now seeing renewed buyer interest as people seek affordability.
What is the Case-Shiller Index?
The S&P Case-Shiller Home Price Index tracks changes in single-family home values by measuring repeat sales of the same properties over time. It’s considered the gold standard for home price data because it controls for quality and location by comparing the same homes. The index is reported as a three-month rolling average, so May data includes sales closed in March, April, and May.
Should I wait to buy a home until prices fall more?
Real (inflation-adjusted) prices are falling, but nominal prices remain positive in most markets. Waiting for a dramatic crash may mean missing out on homes in your budget today. Focus on your financial readiness—stable income, down payment saved, affordable monthly payment—rather than trying to time the market. Mortgage rates at 6.5% are significantly higher than a few years ago, so run the numbers carefully.
How does this compare to the 2008 housing crash?
This is not 2008. The current market is characterized by slow growth and affordability challenges, not a collapse driven by subprime lending and foreclosures. Home prices are up nominally, just not keeping pace with inflation. Lending standards remain tight, and most homeowners have significant equity. The market is cooling, not crashing.
