We Buy Houses In Affton, Missouri. Selling your home via the rent to own strategy is a great option for both the buyer and seller. The seller can collect rent and additional monies, and the buyer can try the house for a while. There are 2 different types of rent to own contracts, the option to purchase, and the agreement to buy. The option to purchase lets the renter decide if they would like to purchase the property at the end of the rental period, while the agreement to buy is a more solid contract where the renter must purchase the home at the end of the rental period. This gives the Missouri home buyers time to build up a deposit and find a financing strategy that works for them. If they end up not being able to qualify for the loan, and they have the option contract, this lets them off the hook and saves you from the headache of legal fees.
