Real estate investment trusts (REITs) are investments that allow you to own a piece of commercial real estate like shopping centers, office buildings, or apartment buildings. REITs give you a share of the money made from renting out the property, and the money is divided up between all the investors who own the REIT. The more people who own the REIT, the more money is divided up between them. This means that if you invest in a REIT, you’re likely to get a small but regular return on your investment.
