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. To compare the costs of owning and renting, we assume buyers get a 3.87% mortgage rate on a 30-year fixed-rate loan with 20% down; itemize their federal tax deductions and are in the 25% tax bracket; and will stay in their home for seven years. Under these assumptions, buying is 35% cheaper than renting nationwide, considering all costs and proceeds from buying or renting over the seven-year period.
