Freddie Mac’s August 20, 2026 release put average mortgage rates at 6.65% for 30-year fixed loans and 5.95% for 15-year fixed loans. The 30-year benchmark fell two basis points from the previous week, but that decline cannot establish whether a client’s offer improved. That requires comparing the client’s rate, upfront costs and lock terms.

What changed in the August 20 release

Freddie Mac published its Primary Mortgage Market Survey (PMMS) results at noon Eastern time. Both fixed-rate averages declined from August 13:

The figures match Freddie Mac’s historical PMMS archive. Two basis points equal 0.02 percentage point. The change shows that the published 30-year average fell; it does not show that every lender lowered its rates by that amount or that Thursday’s pricing was better than Wednesday’s.

Which applications and dates does PMMS cover?

The August 20 release covers application activity from 12:00 a.m. Eastern on Thursday, August 13, through 11:59 p.m. Eastern on Wednesday, August 19, following Freddie Mac’s Thursday-through-Wednesday observation window. It does not include applications submitted on publication day.

PMMS draws on applications submitted through Loan Product Advisor, Freddie Mac’s automated underwriting system. Its methodology, published November 3, 2022, selects conventional, conforming, fully amortizing purchase loans on owner-occupied, one-unit homes. Filters include FICO scores of at least 740 and loan-to-value ratios of 75%–80%, corresponding to roughly 20%–25% down.

Those published filters cover the contiguous states and Washington, D.C., and exclude loan amounts above the national baseline conforming limit. The application submission date is not necessarily the rate-lock date, and some applications never become completed loans.

Why a lender quote can differ from the weekly average

Borrower and loan characteristics

A low-down-payment offer, refinance or investment-property mortgage represents a different comparison from the PMMS population. Even a borrower who fits the profile should treat the average as market context rather than a personalized price.

Credit score, down payment, loan amount, location and loan program can affect an individual rate. The CFPB’s explanation of mortgage rate factors identifies these differences. Document the assumptions behind a quote before comparing it with the benchmark.

Points and lender credits

PMMS no longer publishes average points or origination fees, so 6.65% should not be described as a zero-point offer. Freddie Mac’s PMMS FAQs explain that application data do not consistently supply the information needed to report those costs.

Discount points exchange more money at closing for a lower rate. Rate-related lender credits generally make the opposite trade: less cash upfront and a higher rate. One point equals 1% of the loan amount, not a one-percentage-point reduction in interest. The CFPB explains these trade-offs in its guidance on points and credits.

This distinction is central to comparing mortgage pricing and rates. A lower quoted rate with more points does not, by itself, demonstrate better pricing.

Quote timing and lock terms

Mortgage rates can change daily and sometimes hourly, so a Thursday afternoon quote can differ from an average whose observation window ended Wednesday. The CFPB’s rate-lock guidance also explains that a lock has a deadline and conditions. Receiving a Loan Estimate does not automatically mean the rate is locked; check page 1 and obtain the lender’s lock terms.

What would show that an individual offer improved?

To assess a lender’s change over time, request dated pricing for the same borrower and loan assumptions. To assess competitiveness, compare lenders’ offers at closely matched times. The CFPB cautions that Loan Estimates issued on different days can differ because the market moved.

For either comparison, keep the loan amount, down payment, property, credit assumptions, program and term consistent. Match the lock duration and record whether each rate is locked or floating.

Compare the interest rate alongside points, other origination charges and lender credits. The Loan Estimate explainer helps locate and interpret these charges. Lower estimated taxes or insurance alone do not demonstrate a better lender offer.

Hypothetical example: A lender quotes the same borrower 6.75% on two dates but reduces points from 0.50 to 0.25. Assume the loan, lock duration, other charges and credits are unchanged. The upfront price improved even though the interest rate did not. Conversely, a lower rate accompanied by higher charges requires a cost comparison over the borrower’s expected time in the loan.

Before telling a buyer that financing became cheaper, identify exactly what changed in the written offer.
