"Analyzing Realty Income: A High-Yield REIT Stock Worth Considering"

Realty Income, an ultra-high-yielding real estate investment trust (REIT), is considered a buy due to its consistent dividend growth, historically attractive yield of around 5.7%, and a well-diversified and low-risk portfolio. On the other hand, AGNC Investment, a mortgage REIT, is advised to be avoided by conservative income investors due to its complex business model, declining dividend history, and the risk associated with the mortgage REIT sector.
