Homeownership remains cheaper than renting in all 100 largest U.S. metro areas. In fact, buying is 35% cheaper than renting now, compared with 33% cheaper one year ago. Paradoxically, home price growth nationally has outpaced rents over the past year. So what gives? Two things. First, the 30-year fixed-rate mortgage rate has fallen from 4.5% in 2014 to 3.87% today (as of April 15). Second, the 3.9% home price gain wasn’t much larger than the 3.7% gain in rents. In the past year, these two trends have made homeownership even more affordable compared with renting.
