What to review: No change is mandatory: review the National MI bulletin to see that the construction-to-permanent commitment period, which lenders may now use at 18 months, effective systematically June 6, 2026, applies to loans with National MI mortgage insurance using that commitment period.

QC implications

• Where a loan with National MI mortgage insurance uses a construction-to-permanent commitment period, check that the commitment period applied matches the period in effect for that loan.
• The 18-month period is effective systematically June 6, 2026, so sample affected loans around that date to confirm the correct period was used.
