Single-family rental investors in the New Haven metro are earning some of the best returns on their investment in the country, according to a new analysis by real estate data firm ATTOM.

The company published an analysis of annual gross rental yield on three-bedroom properties in 212 counties nationwide and found that these properties in New Haven County saw a 23.3 percent annual increase in gross rental  yields in the first quarter, putting it in fourth place among the nation’s top 10 and earning it the designation as a “growth county” for SFR investment. Gross rental yield is defined as annualized gross rent income divided by the asset purchase price.

Other parts of the country that saw similarly fast growth in gross rental  yield included Camden County, NJ (38 percent increase), Gloucester County, NJ (30.9 percent) and Polk County, IA (26.3 percent).

ATTOM projected that the average annual gross rental yield on three-bedroom properties will be 7.5 percent in 2023, up from an average of 6.7 percent in 2022. Some of the biggest increases this year are likely to be in several Florida areas like Indian River County, Sebastian-Vero Beach and Collier County in the Naples Beach area.
