A delinquency results when a home owner has failed to make mortgage payments when mortgage payments are due. For most mortgages, payments are due on the first day of the month. Many lenders may not charge a “late fee” until after the 14th day of each month. Even though this is the case, the payment is still considered to be late and the loan delinquent. When a loan payment is more than 30 days late, most lenders report the late payment to one or more credit bureaus.
