Private mortgage insurance

Private mortgage insurance is mortgage insurance that may be required when borrower equity is low.

Plain-language meaning

Private mortgage insurance, often shortened to PMI, is typically connected to mortgage loans where the borrower has a smaller down payment or higher loan-to-value ratio. It protects the lender, not the borrower.

Example

A borrower financing 95% of a home purchase may be asked to pay mortgage insurance depending on loan type, lender rules and country-specific regulation.

Limitations

PMI rules are country- and product-specific. A generic calculator can estimate the payment effect of a user-entered PMI rate, but it cannot determine eligibility, cancellation rights or exact lender pricing.
