The best U.S. cities for house flipping in 2026, ranked by return

House flipping trends are shifting across the U.S.—with national profits feeling the squeeze from rising purchase prices, higher borrowing costs, and extended renovation timelines. The current average gross profit margin sits at 25.4%, and the typical flip now takes around 165 days. However, cities with a larger share of older, reasonably priced homes are still seeing impressive returns, with margins ranging from 62% to 86%. As someone deeply familiar with the dynamics of markets like Baltimore, Baltimore County, Harford County, Anne Arundel, and Howard, I know how local property age and affordability can directly impact your investment potential.
