Buying a home is still cheaper than renting one in every one of the top 100 metro markets, but rising home prices and mortgage rates are making the equation more complicated.

Nationally, it’s 38 percent cheaper to buy than to rent a home right now, according to a new report from Trulia, the real estate online marketplace. The report assumes that owners receive a 4.5 percent mortgage, stay in their home for at least seven years, and are in the 25-percent income tax bracket. Last year, it was 44 percent cheaper.
