Realty Income (O 0.49%) is a wealth-creating machine. The real estate investment trust (REIT) dishes out a growing stream of dividend income. On top of that, its stock has steadily grown in value. These two value drivers have added up to a very attractive total return over the past decade.

Realty Income pays a steadily rising monthly dividend. The REIT has raised its dividend payment 127 times since its initial public market listing in 1994, including the past 108 quarters in a row. Because of that, investors have collected a growing stream of dividend income over the past decade.

An investor who purchased 100 shares 10 years ago would have initially received about $219 in dividend income during the first year based on its payment at the time. That's a nearly 5.9% dividend yield on an initial investment. That income stream would have steadily grown, reaching its current annualized level of $308. That's a 40% increase from the initial annual level. They would have collected a cumulative $3,077 in dividends during that decade. Meanwhile, the initial investment now yields 8.2%.

That income is only part of the return. Shares of Realty Income have steadily appreciated as the REIT invested in expanding its portfolio of income-producing properties, which has increased its funds from operations (FFO) per share by around 5% per year. That has helped grow the REIT's share price by over 50%. As a result, the initial investment is now worth about $5,742. That's in addition to getting more than 80% of the initial investment back in dividend income. Add it up, and the 100-share purchase would have grown from $3,733 to $8,819 in total value. That investment is also throwing off about $310 (and growing) of annual dividend income.

Realty Income is a slow and steady wealth creator that generates a growing stream of dividend income from an increasingly more valuable investment.
