A Vendor Take Back mortgage or VTB or Seller Financing. What is it, how does it work, how do you explain it to a seller and what are the benefits to you and to the seller. We did many of these and they work especially well with a motivated seller or in a market that is not moving quickly. They become the bank for you, you pay them interest so they make more money, and that interest is covered by the rent that you charge on the investment property. Win win win.
