"Because of the strong dividend income REITs provide, they are an important investment both for retirement savers and for retirees who require a continuing income stream to meet their living expenses. REITs' dividends are substantial because they are required to distribute at least 90% of their taxable income to their shareholders annually. Their dividends are fueled by the stable stream of contractual rents paid by the tenants of their properties," says REIT.com.
