Try to purchase real estate in high-demand areas and locality, then rent it out long-term or as a short-term vacation rental (e.g., Airbnb) or depending upon your local styles. Use property management services to handle maintenance, tenant issues, and day-to-day operations. Ensure your rental income covers mortgage, taxes, and maintenance costs, while generating a profit. Over time, the property’s value may also increase, providing additional long-term gains.
