Residential mortgage insurance companies send this transaction set to respond to insurance applications submitted by lenders or brokers. The 263 provides the insurer’s decision on a mortgage insurance application, including approval status, terms, and any applicable conditions or requirements. Key segments include the BGN (Beginning Segment) which establishes the response context, the MIR (Mortgage Insurance Response) segment which conveys the underwriting decision and policy details, and the N1 (Name) segments which identify the parties involved in the transaction such as the borrower, lender, and property parties.

For example, when HomeGuard Insurance receives a mortgage insurance application from Premier Mortgage Group for a residential property, HomeGuard underwriters evaluate the application and generate a 263 response. This response includes the MIR segment confirming approval of the insurance with specific coverage amounts and premium terms. If conditions apply—such as requirements for additional appraisals or documentation—HomeGuard includes TXI (Tax Information) and N9 (Reference Identification) segments to communicate these requirements. Premier Mortgage Group uses the 263 to determine next steps, confirm insurance is in place, and proceed with loan closing or request additional information from the borrower if conditions must be satisfied.
