BOSTON ( TheStreet) -- Real estate investment trusts don't pay corporate taxes as long as they derive 75% of their income from rents and distribute at least 90% to shareholders. Distributions are taxed as income. The following top-ranked REITs offer high yields.

5. Omega Healthcare Investors ( OHI) owns long-term care facilities.

The stock: Omega has gained 57% in the past year. It sells for a price-to-projected-earnings ratio of 16, a discount to peers.
