Steady income:
Get monthly rental income that could cover your expenses and make you extra money. This typically goes up over time as rents increase and your mortgage is paid off.
Long term financial security:
Your real estate holdings can go up in value. While the mortgage is being paid down, the property value also increases over time generating more equity for you as the owner.
Tax Benefits:
Rental income is not subject to self-employment tax and the government also offers tax breaks for insurance, maintenance, legal fees, property taxes, and professional property management as well as property depreciation.
Appreciation:
Real estate is a long-term investment and over time the capital assets (i.e. land) go up in value.
Inflation:
Investing in real estate is a good hedge against inflation. When there's high inflation, your rental income and property value increase.
