One of the biggest advantages of owning real estate is that your property can become a source of capital for your next investment. Many investors make the mistake of thinking they have to save another $50,000 or $100,000 before they can purchase another property. But if your existing property has appreciated significantly, you may already have the money you need sitting in the equity. One strategy investors use to access that equity is a Home Equity Line of Credit, or HELOC.
