A real estate investment trust (REIT) is a company that owns, operates, or finances income-producing real estate. Investors can purchase shares of a REIT, which allows them to benefit from the income generated by the properties without having to directly own or manage them. REITs offer a convenient way for individuals to invest in real estate without the hassle of property management. Additionally, they provide diversification and liquidity as shares can be bought and sold on the stock exchange. With potential for steady income and long-term growth, REITs are a popular choice for those looking to add real estate to their investment portfolio.
