can The administrator sell property belonging to the estate with renters still in it if buyer assumes the responsibility?

People were informed In December verbally that all property was going up for sale. Called and informed me could not make the rent for February and was given verbal 30 day notice at that point offer was made to buy all properties including that one with her still in it. No legal lease was made between renter and deceased landlord. Property is junked up and others living in the unit as well
