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.
If you want to do it yourself, state-specific contracts for deed are available for purchase online, or you can hire a lawyer to make sure everything is legally valid. In addition to the contract terms, the contract for deed must include your name and address, the seller's name and a legal description of the property. Sign the document, along with the seller, and have it notarized. Then file the document at the recorder's office for the county in which the property lies.
