Moody's Mark Zandi rolls up a 55-city list of buy-to-rent ratios, and guess what? Renting makes more sense in most places, just like it did six months ago, in spite of what you might have thought about home prices' decline during that period. Factors that kept prices sticky were a home buyer tax credit that steadied non-distressed sales well past mid-year, and the wrench in the work for foreclosure sales in the past couple of months. Likely, the next six months should show improvement to the buy side, as rents are on the up and up, and distressed sales are going to resurface with a vengeance, weighing selling prices down.
