Critical Program Nuance to Note
Conventional mortgage loans utilize standard **PMI (Private Mortgage Insurance)** rather than government guarantee pools. PMI exists solely to protect the lender and cancels automatically under the Homeowners Protection Act of 1998 when your loan-to-value (LTV) ratio drops to 80% through principal payments or home value appreciation. If you pay less than 20% down, the PMI rate is heavily adjusted based on your FICO credit score, creating a massive premium savings for high-score borrowers.
