Is there anyway to know home many single family homes are currently being offered as rentals?Looking to figure out how many homes are being listed under rentals by metro.

I'm guessing that the Market Report rental numbers have to be based a certain number of observations, so this data should exist somewhere, right?February 04 2013 - Francis00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
