The issue is especially acute in some Sun Belt states amid evidence that investors often can outbid other buyers, keeping starter homes out of the hands of would-be owners, especially suburban Black and Hispanic families. Some local officials in those states are pushing for increased regulation of investor purchases, but many Republican lawmakers oppose such controls.

Investors bought 24% of all single-family houses sold nationwide last year, up from 15% to 16% annually going back to 2012, according to a Stateline analysis of data provided by CoreLogic, a California-based data analytics firm. That share dipped only slightly in the first five months of 2022 to 22%.
