By region, sales rose in the Midwest, Northeast and South but fell in the West. 

The chief economist for the National Association of REALTORS® also predicts home prices will climb 4% compared to 2025. 

Nationwide, the median price for a single-family home increased 1.7% year over year to $426,800. Prices increased by the same annual rate during the second quarter.

Nationally, home sales in the 52 metro areas surveyed by RE/MAX increased 8.5% year over year for the fourth time in 2025, but declined 4.6% month over month.
