Mortgage insurers use this transaction set to receive applications for residential mortgage insurance coverage from lenders, mortgage brokers, and loan originators. The receiving insurer uses the application data to evaluate risk and determine eligibility for insurance. Typically sent in response to a lender’s need to insure a mortgage loan, the transaction communicates detailed loan characteristics, borrower information, and property details necessary for underwriting. The BGN (Beginning Segment) establishes the application context and timestamps, the LRQ (Mortgage Characteristics Requested) segment specifies the insurance coverage being sought along with loan structure details, and the IN1/IN2 loops (Individual Identification and Name Structure Components) convey borrower demographic and financial information essential to risk assessment.

For example, Premier Bank originates a mortgage for a borrower and needs mortgage insurance to support the loan approval. Premier Bank submits an X12 872 transaction to United Mortgage Insurance Corporation, including the borrower’s income, credit profile, down payment percentage, and property appraisal value through the structured LN1 (Loan Specific Data), BFS (Borrower Financial Summary), and PAS (Property Appraisal Summary) segments. United Mortgage Insurance processes the application, evaluates the risk based on loan-to-value ratio and borrower creditworthiness data captured in the SCS (Credit Score) loops, and determines whether to approve the insurance and at what premium rate.
