NAR: Housing affordability at record high

A U.S. housing affordability index compiled by the National Association of Realtors reached a record high in the first quarter.

NAR’s affordability index gauges whether a median-income family could qualify for a conventional mortgage loan on a median-priced, existing single-family home. The index takes into account mortgage interest rates and assumes a 20 percent down payment and a monthly principal and interest payment not exceeding 25 percent of the gross median family monthly income.
