Occasionally, the new owner will agree to rent to you for a limited period of time. Typically, you will be required to sign a signed rental agreement and pay rent. A “lease back with buy” deal should be avoided at all costs. The person that is leasing the property to you may simply be interested in receiving a large down payment and then terminating the lease agreement due to a minor default. You’re still out of the house, and they keep your money.
To avoid eviction, make a written agreement to vacate by a specific date. The new owner may agree to give you a little more time to arrange to move in order to avoid the new owner going to court to evict you. There is no legal requirement that the owner do this.
