With institutional investors playing a major role in the home-buying market as they snagged tens of thousands of homes in 2012, RealtyTrac set to work to determine which markets still offer the best opportunities for investors intending to purchase single-family homes to rent. Topping the list of top 20 markets were Memphis, Tennessee; Saginaw, Michigan; Toledo, Ohio; Ocala, Florida; and Las Vegas, Nevada. In Memphis, Tennessee, the median sales price for a three-bedroom home is $72,605, and investors can expect a cash purchase capitalization rate of 10.38 percent.
