Weekly mortgage rate update

Every Thursday, Freddie Mac publishes its Primary Mortgage Market Survey® (PMMS) — the most widely cited snapshot of average mortgage rates in the country. The latest release (August 20, 2026) brings us a second consecutive week of declines, offering a meaningful reprieve after the five-week upward trend we tracked through July and early August. Here is the data and what it means if you are buying, selling, or refinancing in the Tri-Cities.

This week’s rates

Data sourced from Freddie Mac’s PMMS release for the week ending August 20, 2026:

Source: Freddie Mac Primary Mortgage Market Survey®, week ending August 20, 2026. Rates assume a credit score of 740, 20% down payment, and 0.7 discount points. Actual rates vary by borrower profile. Note: Freddie Mac discontinued reporting the 5/1 hybrid ARM rate in late 2022 as part of a survey modernization.

What happened this week

This week marks a second consecutive decline for both the 30-year and 15-year fixed-rate products. The 30-year fixed edged down two basis points to 6.65%, following last week’s two-basis-point drop from 6.69% to 6.67%. The 15-year fixed dipped one basis point to 5.95%, after last week’s five-basis-point decline from 6.01% to 5.96%. Combined, the two-week rollback has shaved four basis points off the 30-year fixed and six basis points off the 15-year fixed.

Freddie Mac Chief Economist Sam Khater titled the August 20 release “Mortgage Rates Decline for Second Consecutive Week,” and described the market as follows: “Mortgage rates declined for the second straight week as the Federal Reserve signaled that interest rate cuts could begin later this year. Today’s rate drop translates into a slightly more favorable environment for prospective homebuyers, who remain sensitive to changes in affordability.” That is the most optimistic language we have heard from the PMMS in months — a clear signal that the tone around rates is shifting.

After five consecutive weeks of increases that pushed the 30-year fixed from 6.43% to 6.69%, this two-week reversal is a meaningful change in direction. Two weeks does not make a trend, but it does break the momentum of what had been a sustained and worrying upward pattern. The 30-year fixed at 6.65% is now back to nearly the same level we saw in early August — before the peak at 6.69% — and the 15-year at 5.95% is at its lowest level since late July.

Compared to this time last year (when the 30-year fixed averaged 6.58%), today’s 6.65% is seven basis points higher. The year-over-year comparison has shifted slightly less favorable than it was a few weeks ago, but the gap is still narrow — and the trend is now pointed in the right direction.

What does 6.65% actually mean for your payment?

Let me put real numbers to this. If you are purchasing a $400,000 home in the Tri-Cities with 20% down ($80,000), your loan amount would be $320,000. Here is what that looks like at today’s rates:

Compared to the recent peak of 6.69% two weeks ago, that is a decrease of roughly $11 per month on a $320,000 loan — or about $3,960 saved over 30 years. Compared to five weeks ago when rates were at their recent low of 6.43%, today’s 6.65% is still 22 basis points higher — which adds about $52 per month in cost. The takeaway: we have come off the peak, but we are not back to the early-summer lows.

The 15-year fixed at 5.95% costs more each month (about $638 more than the 30-year) but saves approximately $255,000 in total interest over the life of the loan. For buyers with room in their monthly budget, that remains one of the most powerful wealth-building tools available in today’s market.

The outlook from Fannie Mae

Fannie Mae’s Economic and Strategic Research (ESR) Group published its August 2026 Economic and Housing Outlook on August 17, and the update sent ripples through the housing world. The August outlook sharply raised the rate forecast compared to the July edition, driven by persistent inflation risks linked to global supply chain disruptions and geopolitical tensions.

Key projections from the August 2026 outlook:

Fannie Mae now expects the 30-year fixed mortgage rate to average 6.7% in Q3 2026 and 6.8% in Q4 2026, holding near that elevated level through the first half of 2027 before easing only slightly to 6.7% in the second half of 2027. That is a significant revision from the July outlook, which had called for rates to average 6.4% through the rest of 2026 and decline to 6.3% in early 2027. The revision reflects a cautious reassessment of the economic landscape — particularly inflation risks that have not dissipated as quickly as expected.

On home sales, Fannie Mae projects steady but constrained activity. They see total housing starts at approximately 1.36 million units annually through 2026, with a slight dip to 1.34 million in 2027. Home price growth is forecast at approximately 3.2% in 2026 and 1.9% in 2027 — still positive but moderating.

The overall tone of the August outlook is notably more cautious than prior months. Fannie Mae is signaling that homebuyers may need to wait until mid-2027 for meaningful mortgage rate relief. However, today’s actual rate of 6.65% is actually slightly below Fannie Mae’s Q3 forecast of 6.7% — meaning the market is already performing a touch better than the forecast anticipated. That is a small but meaningful gap worth noting.

Fannie Mae continues to highlight the “lock-in effect” — homeowners with sub-4% pandemic-era mortgages who are reluctant to sell — as a key headwind for inventory. In the Tri-Cities, steady in-migration from higher-cost West Coast markets continues to meet constrained supply, which supports home values even as rates stay elevated.

What this means for Tri-Cities buyers

Two consecutive weeks of declines — however modest — is the most positive rate news we have seen in over a month. After five weeks of steady increases that pushed the 30-year from 6.43% to 6.69%, the reversal is a welcome psychological shift. Two basis points this week and two last week does not signal a dramatic market turn, but it does break the pattern and opens the door to further easing.

Here is what I want you to hear, especially if you are a first-time buyer who has been feeling the pressure of watching rates climb: the trend has changed direction. For the first time in six weeks, the direction is down. And with the Federal Reserve signaling that interest rate cuts could begin later this year, there is a genuine path to lower rates ahead — even if Fannie Mae’s revised forecast suggests the path will be gradual.

In the Tri-Cities, a $400,000 home in Kennewick, Richland, Pasco, or West Richland still delivers outstanding value. At 6.65%, your monthly payment on a 30-year fixed is roughly $2,054 before taxes and insurance. That payment is building equity in one of the most resilient and affordable housing markets in Washington. And with the potential for rate cuts later this year, locking in today and refinancing when rates ease further is a proven, smart strategy.

If you have been waiting, the honest truth is this: the best time to buy has never been about hitting the absolute rate bottom. It is about being ready, finding the right home, and building equity over time. Today’s rates — even at 6.65% — are workable, and with the trend now pointed down, the outlook is more encouraging than it has been all summer.

What this means for sellers

Two consecutive weeks of rate declines is good news for sellers too. Lower rates expand the pool of qualified buyers, and the psychological boost of seeing rates move down — rather than up — creates a more confident buyer mindset. If you have been considering listing your home, this week’s data provides a small but real tailwind.

The Tri-Cities continues to attract relocating families from Seattle, Portland, and California who are seeking more space and better value. Inventory is still constrained, demand remains consistent, and well-priced, well-presented homes are drawing strong interest. With rates showing signs of stabilizing and now declining slightly, the window for sellers remains wide open.

The bottom line

For the second straight week, mortgage rates declined. The 30-year fixed sits at 6.65% (down two basis points), and the 15-year fixed at 5.95% (down one basis point). Combined, the two-week rollback has shaved four basis points off the 30-year and six off the 15-year. Freddie Mac’s Chief Economist noted that the Federal Reserve’s signals about potential rate cuts later this year are contributing to a “slightly more favorable environment for prospective homebuyers.”

Fannie Mae’s August outlook revised its forecast upward — now expecting rates to average 6.7% to 6.8% through late 2026 and into early 2027 — but today’s actual rate of 6.65% is already slightly below that projection. The revised forecast reflects real-world inflation concerns, but the immediate data is telling a slightly more optimistic story.

Two weeks of declines do not make a new trend, but they do break the old one. The direction has shifted, and for buyers and sellers who have been waiting on the sidelines, that shift matters. Homeownership is about building a future for your family — not timing a market bottom. If you are ready to buy, sell, or simply explore your options, I would love to sit down with you and map out what is possible in this market, at these rates, for your specific situation.
