Sanchez bought a house for $100,000, paying $10,000 down and financing the balance through a local bank. As part of the closing costs, Sanchez was required to take out private mortgage insurance to protect the bank in case she defaulted on the mortgage. She had an excellent credit rating and always paid her mortgage payments when they were due. Two years after buying the property, she received an inheritance and used the money to pay an additional amount of $10,000 to the bank toward the principal of the loan. Hoping to cut down on her monthly pa y ments, she asked the bank to cancel the mortgage insurance, but the bank refused. Does Sanchez have any rights in this situation? Explain.
