How to use it safely

Freddie Mac says PMMS is based on mortgage rates in qualifying purchase applications submitted through Loan Product Advisor from lenders across the country. It is a national weekly average, not a personalized or same-day lender quote.

Weekly benchmark questions

Is this rate a loan offer or APR?

No. It is a national weekly benchmark. APR and a lender offer depend on additional terms, costs, borrower details, and product facts.

Why is there a stale warning?

This build has no live rate feed. After the verified observation exceeds the freshness window, the page retains the last sourced record and warns that it may be outdated.

Does the payment estimate include taxes and insurance?

No. It models principal and interest only. Use the full mortgage calculator to add ownership-cost assumptions.
