The key to building a rental property empire is to start small and build your way up.

This means investing in a single property and using the rental income to purchase additional properties.

Next, it's crucial to have a solid property management plan in place.

This includes screening tenants, maintaining the property, and dealing with any issues that arise.

Another important factor is financial management. To retire early, it's essential to have a plan to pay off mortgages and eliminate debt.

This may involve using the income generated from your rental properties to pay down debts and make additional investments.

Finally, it's important to have a long-term strategy in place.

This may include diversifying your portfolio, investing in other asset classes, or even selling properties when the market conditions are right.
