Lease Option

A lease-option or rent-to-own contract for a home is both a standard lease and an option to purchase the home. Under a lease option on a home, you first execute a lease with the seller/landlord. Like any property lease, a lease option creates a landlord/tenant (or lessor/lessee) relationship. Generally, sellers in lease-option contracts have to put part or all of the rent you pay them toward the home's final purchase price.
Land Contract

In a typical land contract, you and the seller would execute a purchase contract, with the seller financing your purchase. Although you won't gain actual title to your home under a land contract, you'll gain an equitable title and interest in the property. Once you've paid the seller in a land contract off, he'll convey the actual title to you. Under a land contract, you have the right to improve and even rent your home.
