BOSTON (TheStreet) -- Compelling demographics, including "echo boomers" leaving the nest, and a still-struggling single-family housing market are pushing rents higher for real estate investment trusts (REITs) focused on apartment buildings.The appeal of REITs isn't just their share-price appreciation potential, but their high dividends, which make them attractive for yield hounds. For example, apartment REIT Essex Property Trust ( ESS) is up 12% this year and 40% over the past three years, on average, and currently yields 2.82%. The S&P 500 is up 9.6% this year. Standard & Poor's says the "fundamental outlook for the residential REITs sub-industry is positive. We believe a lower homeowner rate, despite government incentives and modest new supply (new construction), are both working in favor of multi-family operators." S&P Capital IQ says that as the home-ownership rate ticks lower, "many Americans may be reluctant to purchase a home until price stability returns. As the economic recovery gains steam, we expect an increase in new household formations." 7 Dividend Stocks You Can't Ignore Right Now >> And it adds that new supply is at multi-year lows.
