Technically you can purchase a property for $10 if the person is willing to sign their DEED over to you. Most people, however, have LIENS against their property in the form of mortgages. But imagine if you took their property from them with their current mortgage in place. Imagine if they were motivated to do this because of a pending FORECLOSURE. Imagine that you were able to reach out to them and get their property under contract. You would then be able to see that they purchased their property 5 years ago and have TONS of equity, but CAN'T TOUCH IT because they are in arrears. So how is it that YOU can get to their equity? Well....you may not have the cash to catch them up on their payments and take over CONTROL of their property, but there are thousands of investors that DO have the money and will gladly pay you a finders fee of $1500-$5000 to bring the deal to them.
The process I just briefly glossed over is called PRE-FORECLOSURE investing and the method of taking control is SUBJECT TO.....subject to the existing lien in place. It's a beautiful thing because you could keep their mortgage in place ...but then FIND another renter that will pay YOU more than the mortgage note....who gets to pocket the rest....
YOU DO!
