Rent-backs allow you to stay in your home even after it sells, until a specific date, on the condition that you pay rent to the new home owners. It’s basically like renting the home you had previously owned.  In order to make this happen, you need to see if the new owners are open to it (they might say no because they might be in the same predicament of needing a place to live). If they agree, a security deposit will be set up and you’ll essentially lease your place from the new owners.
