Five years ago, Hensley purchased a house. At that time, being unable to pay the full purchase price, she borrowed funds from Thrift Savings and Loan, which in turn took a mortgage at 6.5 interest on the house. The mortgage contract did not prohibit the assignment of the mortgage. Then Hensley secured a new job in another city and sold the house to Sylvia. The purchase price included payment to Hensley of the value of her equity and the assumption of the mortgage debt still owed to Thrift. At the time the contract between Hensley and Sylvia was made, Thrift did not know about or consent to the sale. On the basis of these facts, if Sylvia defaults in making the house payments to Thrift, what are Thrift’s rights? Discuss.
