Real Estate Investing Fundamentals

Learn how rental properties really make, and lose, money.

Real estate investing can build long-term wealth, but it is a business with real costs and real risks. The investors who last are the ones who run the numbers honestly before they buy.

This area explains how rental properties earn income, what it costs to operate them, how cash flow and vacancies work, how financing and maintenance change the picture, the main risks, and how real estate fits into a long-term plan. All examples are hypothetical, and investing always involves risk.
