The first real estate investment trust, or REIT, on this list, Iron Mountain specializes in storage and information management services. The company claims to store and protect $18 billion in assets from more than 225,000 organizations globally. IRM's legal structure as a REIT allows it to avoid double taxation. It must pay out 90% of taxable income to its shareholders, but in exchange, it pays no corporate taxes. Investors willing to prioritize steady income over meaningful growth potential should consider Iron Mountain. Shares tend to trade within a relatively narrow range and currently yield 8.1%.
