Any seller of real estate who retains title to the real estate as security for the purchase price and who does not convey title to the purchaser or take back a deed to secure debt shall execute and deliver to the purchaser a bond for title which shall correctly set forth the unpaid portion of the purchase price and the maturity of the indebtedness. If any part of the purchase price falls due more than three years from the date of the instrument, the seller shall have the instrument recorded before delivery of the bond for title in the county where the land is located and shall pay the tax required by this article for the recording of the instrument.
