Sources of Investment Capital and Leverage

Real estate assets are typically very expensive in comparison to other widely-available investment instruments (such as stocks or bonds). Only rarely will real estate investors pay the entire amount of the purchase price of a property in cash. Usually, a large portion of the purchase price will be financed using some sort of financial instrument or debt, such as a mortgage loan collateralized by the property itself. The amount of the purchase price financed by debt is referred to as leverage. The amount financed by the investor's own capital, through cash or other asset transfers, is referred to as equity. The ratio of leverage to equity (often referred to as "LTV", or loan to value for a conventional mortgage) is one mathematical measure of the risk an investor is taking by using leverage to finance the purchase of a property. Investors usually seek to decrease their equity requirements and increase their leverage, so that their return on investment (ROI) is maximized. Lenders and other financial institutions usually have minimum equity requirements for real estate investments they are being asked to finance, typically on the order of 20% of appraised value. Investors seeking low equity requirements may explore alternate financing arrangements as part of the purchase of a property (for instance, seller financing, seller subordination, private equity sources, etc.)

Some real estate investment organizations, such as real estate investment trusts (REITs) and some pension funds, have large enough capital reserves and investment strategies to allow 100% equity in the properties they purchase. This minimizes the risk which comes from leverage, but also limits potential ROI.

By leveraging the purchase of an investment property, the required periodic payments to service the debt create an ongoing (and sometimes large) negative cash flow beginning from the time of purchase. This is sometimes referred to as the carry cost or "carry" of the investment. To be successful, real estate investors must manage their cash flows to create enough positive income from the property to at least offset the carry costs.
