Any means by which the ownership of a property changes hands. Lenders consider all of the following situations to be a transfer of ownership: the purchase of a property "subject to" the mortgage, the assumption of the mortgage debt by the property purchaser, and any exchange of possession of the property under a land sales contract or any other land trust device. In cases in which an inter vivos revocable trust is the borrower, lenders also consider any transfer of a beneficial interest in the trust to be a transfer of ownership.
