The four states international buyers ask about most: New York up 5.2% on the year, California at a 4.22% yield, and what Texas and Florida really cost.
Indiana, Missouri and Ohio in 2026: state gains of 3-3.5% on the year with yields of 5.75-6.61%, and the secondary cities quietly outperforming the metros.

Ohio in 2026: a $251,502 state median up 3.5% on the year, with Cleveland at a 14.13% gross yield and Columbus at 6.96% — and what separates the two.
