The 2016 share of home purchases using Federal Housing Administration loans nationwide was 15.5%, up from 15.4% in 2015, according to Attom Data Solutions. But the program's outlook for 2017 is murky. If a planned 25-basis-point cut to the mortgage insurance premium had remained in place, there might have been a 12% increase in FHA purchase volume this year. But one of the first things the Trump administration did after the inauguration was to suspend the planned reduction. On the other hand, FHA should benefit from this year's expected increase in first-time homebuyers. Here are the 10 metropolitan statistical areas with population over 200,000 that had the largest percentage of purchases using FHA-insured loans in 2016, according to Attom Data Solutions.
