More renters live in 1-to-4 unit homes than apartment buildings

Developments - WSJ: Here’s a fun fact about the housing market: There are more rentals in houses than apartment buildings.
That number comes from CoreLogic economist Sam Khater, who crunched Census numbers to determine that about 20.7 million rentals are in 1-to-4 unit homes, including both detached and attached homes, compared with about 17.1 million rentals in buildings with 5-or-more units. About 1.87 million American households are in mobile homes, RVs, boats, or vans.
