Underwriting Guide, summaries and more
MGIC Underwriting Guide
Our Underwriting Guide (UWG) provides the policy, procedures and guidelines we use to evaluate loans for mortgage insurance. On a case-by-case basis, we will consider insuring loans that don’t meet requirements stated in our Guide. We’ve organized our Guide as follows:- Section 1 – Doing Business with MGIC provides information about working with us
- Section 2 – MGIC Go! Loans focuses on loans with a valid DU Approve or Loan Product Advisor Accept response
- Section 3 – Standard Loans covers loans that are not processed through an Agency AUS or that do not qualify for MGIC Go!
