What is a Contract for Deed? A Contract for Deed (or Land Contract) is a contract for the purchase of real property (real estate) in which the seller retains the deed (title) to the property until the purchaser makes payments in installments equal to the agreed upon purchase price.
Make a Purchase Agreement. Just like any sale of real estate, a land contract should begin with a purchase agreement. This is a legal document signed by a potential buyer making an offer on the real property for sale. The purchase agreement should indicate that the offer is for a land contract, and should state the purchase price, initial cash down payment, length of the payment term, and any other terms of sale.
