Investing in real estate for passive income involves acquiring properties with the intention of generating a steady cash flow without actively participating in day-to-day operations. To begin, you can explore options like rental properties, real estate investment trusts (REITs), or crowdfunding platforms. Conduct thorough market research to identify areas with high rental demand and favorable appreciation potential. It's crucial to evaluate property expenses, potential rental income, and calculate your return on investment. Consider factors such as location, property condition, and tenant screening.
