According to ATTOM’s Q4 2025 U.S. Home Affordability Report, in the fourth quarter of 2025, median-priced single family homes and condos were less affordable than historical averages in nearly every county with sufficient data available for analysis.
The report also indicated that in 99 percent (586 of 594) of the counties analyzed by ATTOM, median-priced single-family homes and condos were less affordable than historical averages in the final quarter of the year. This pattern also held in the prior two quarters, as the national median home price remained near a record high of $365,000.
ATTOM’s latest home affordability analysis revealed that the latest data offered a modest silver lining amid the nation’s affordability challenges. Although homes remained less affordable than historical norms in the vast majority of markets, affordability improved from the third quarter to the fourth quarter of 2025 in 86 percent (511 of 594) of the counties analyzed.
The report stated that over the past five years, the median home sales price has increased 54 percent, reaching $365,185 in the fourth quarter, while typical wages rose 29 percent, according to the most recent U.S. Bureau of Labor Statistics wage data, which covers the second quarter of 2025.
The latest home affordability report found that year-over-year price increases occurred in 69.5 percent (413 of 594) of the counties analyzed. Counties were included in the report if they had populations of at least 100,000 and a minimum of 50 single-family home and condo sales during the quarter.
