Leverage is very important for investors because the less cash you put down on each property the more properties you can buy.
If the properties go up in value your rate of return goes up.
However if the properties go down in value and you have a lot of debt on the property this can result in negative cash flow.
Since real estate is generally cyclical negative cash flow is only a short-term problem and can be handled if you have other income or a cash reserves.
This makes “Nothing down” investing very helpful to protect against negative cash flow for high leverage investor.
If you are a long term real estate investor leverage will work in your favor if the markets in which you invest appreciate in the long run and your income from the properties can pay for most of your monthly debt.
