The recent rise in mortgage rates has made buying a house a little more expensive: the increase in the 30-year fixed rate over the past month from 3.4% to 3.9% (Freddie Mac) raised the monthly payment on a $200,000 mortgage by $56, or 6%. However, because mortgage rates are still near long-term lows, and because prices fell so much after the housing bubble burst and remain low relative to rents even after recent price increases, buying is still much cheaper than renting. That means that the recent jump in rates doesn’t change the rent-versus-buy math much.
Rates are likely to keep rising, but how far must rates rise before buying a home starts to look expensive relative to renting? To answer this, Trulia updated our Rent vs. Buy analysis with the latest asking prices and rents from March, April, and May 2013. Following our standard approach, we calculated the cost of buying and renting for identical sets of properties, including maintenance, insurance, taxes, closing costs, down payment, sales proceeds, and, of course, the monthly mortgage payment on a 30-year fixed-rate loan with 20% down and monthly rent. We assume people will stay in their homes for 7 years, deduct their mortgage interest and property tax payments at the 25% tax bracket, and get modest home price appreciation (see the detailed methodology and example here). Here’s what we found:
Buying remains cheaper than renting so long as mortgage rates are below 10.5%. At 3.9%, the current 30-year fixed rate according to Freddie Mac, buying is 41% cheaper than renting nationally. With a 5% mortgage rate, buying is still 34% cheaper than renting nationally. Mortgage rates would have to rise a huge amount – to 10.5% – to tip the math in favor of renting, which isn’t impossible. Rates were that high throughout the 1980s, but have been consistently below 10.5% since May 1990.
Each local market, of course, has its own mortgage rate “tipping point” when renting becomes cheaper than buying a home. In Denver, buying is a whopping 53% cheaper than renting at the current mortgage rates. Even at 3.9%, buying is cheaper than renting in all of the 100 largest metros, which means the tipping point is above 3.9% everywhere. The tipping point is lowest in San Jose, which would tip in favor of renting if rates reach 5.2%. It’s between 5% and 6% in San Francisco and Honolulu, and between 6% and 7% in New York and Orange County, CA.
