Also known as a seller carry back, it is an agreement in which the owner or seller of the home provides the financing, allowing the buyer to pay all or some of the purchase price over time. This is generally done as a private home mortgage. Seller financing gives home buyers the chance to obtain a mortgage that they might not otherwise qualify for and generally with lower closing costs. For the seller, it means an opportunity to attract a larger number of interested buyers and to overcome any problems with valuation of the property.
