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 most recent release (July 30, 2026) is what we have to work with as we head into the first full week of 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 July 30, 2026:

Source: Freddie Mac Primary Mortgage Market Survey®, week ending July 30, 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

Rates moved up again this week. The 30-year fixed rose to 6.66% from 6.58% last week — an eight-basis-point increase — while the 15-year fixed climbed to 6.04% from 5.96%. This marks the fourth consecutive week of upward movement, a sustained trend that has brought the 30-year fixed from a recent low of 6.43% back to levels we have not seen since late spring.

Freddie Mac Chief Economist Sam Khater characterized the current market this way: “The housing market continues to benefit from more available inventory, providing prospective homebuyers with additional options and helping support buyer activity as mortgage rates fluctuate.” That is a cautiously optimistic note — rates are up, but inventory is improving, and buyers who are prepared still have room to work.

The eight-basis-point jump on both products is the largest single-week move we have seen in over a month. It is still not the kind of whipsaw volatility we saw in 2023 or mid-2025, but it is a clear signal that the gradual upward drift is accelerating. Over the past four weeks, the 30-year fixed has risen a total of 23 basis points (from 6.43% to 6.66%). That is real movement — and it reinforces why waiting on the sidelines carries a concrete cost.

What does 6.66% 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 last week’s 6.58%, that is an increase of roughly $13 per month on a $320,000 loan — or about $4,680 over the full 30 years. Compared to four weeks ago when rates were at 6.43%, the monthly difference is about $55 per month. That adds up to nearly $20,000 in additional interest over the life of the loan. It is not a crisis, but it is a real cost of waiting. The 15-year fixed at 6.04% costs more each month — about $647 more — but saves approximately $252,000 in total interest over the life of the loan compared to the 30-year. That remains one of the most powerful wealth-building moves available to buyers who can manage the higher payment.

The outlook from Fannie Mae

Fannie Mae’s Economic and Strategic Research (ESR) Group published its July 2026 Housing Outlook, and the news is slightly more encouraging than you might expect given this week’s rate increase. Their updated forecast projects the 30-year fixed mortgage rate will average 6.4% through the remainder of 2026, with a decline to approximately 6.3% by the first quarter of 2027 — slightly earlier than their prior forecast suggested. Over the 2026-2027 period as a whole, Fannie Mae expects the 30-year to average around 6.3%.

That is meaningful context: even with this week’s jump to 6.66%, Fannie Mae’s economists still see rates settling lower over the next six to twelve months. The forecast acknowledges that persistent inflation and strong consumer spending have kept upward pressure on rates recently, but they expect those pressures to ease as we move into 2027.

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, that dynamic is alive and well: steady in-migration from higher-cost West Coast markets meets constrained supply, which continues to support home values even as rates drift higher. Fannie Mae’s economists expect a moderate housing rebound over the next 12 to 18 months as rates eventually ease and more inventory comes to market.

The key takeaway from Fannie Mae: rates are near their peak for this cycle, with gradual easing expected through late 2026 and into 2027. For buyers, that suggests that locking in today and refinancing when rates come down is a smart, proven path forward. For sellers, it means the window of strong buyer purchasing power is still open — but may narrow as rates stay elevated.

What this means for Tri-Cities buyers

This is the fourth straight week of rate increases, and eight basis points is the biggest single-week move we have seen in over a month. Does that mean you should rush into a decision? No. But it does mean that the cost of waiting is becoming more concrete by the week. Since late June, the monthly payment on that $400,000 home has gone up by about $55 — roughly $660 per year in additional housing cost. That is not a make-or-break number for most qualified buyers, but it is a real and accumulating expense.

Here is what I want you to hear, especially if you are a first-time buyer feeling nervous: you do not need to time the market perfectly. You just need to find the right home for your family at a payment you can manage. In the Tri-Cities, a $400,000 home in Kennewick, Richland, Pasco, or West Richland still offers excellent value — four bedrooms, a two-car garage, and a yard. At 6.66%, your monthly payment on a 30-year fixed is roughly $2,057 before taxes and insurance. That is a meaningful payment, but it is building equity in one of the most resilient and affordable housing markets in Washington. And with Fannie Mae projecting rates to ease into 2027, locking in today and refinancing later could give you the best of both worlds: a home now and a lower payment down the road.

What this means for sellers

Four consecutive weeks of rate increases will eventually affect buyer purchasing power — and 6.66% on the 30-year is a psychological threshold that some buyers may find intimidating. That said, inventory remains tight across the Tri-Cities, demand is steady, and well-priced homes in good condition are still drawing attention. Sam Khater’s point about improving inventory is actually good news for sellers too: more options mean more serious traffic through your open house.

The region continues to attract families relocating from Seattle, Portland, and California who are seeking more space and better value. If you have been considering selling, the current rate environment still favors sellers — but if rates continue to climb, buyer budgets will shrink. Listing while rates are in the mid-6% range gives you the widest pool of qualified buyers. If you wait until the market adjusts to 7% or higher, that pool narrows. The strategic move is to act now, not later.

The bottom line

Rates rose eight basis points this week — the biggest single-week increase in over a month and the fourth consecutive week of upward movement. The 30-year fixed sits at 6.66% and the 15-year at 6.04%. Year-over-year, rates are still slightly lower than the 6.72% we saw this time last year, and Fannie Mae’s latest forecast projects gradual easing toward 6.3% by early 2027.

The trend is worth paying attention to, but it should not dictate your life decisions. Homeownership is about building a future for your family, not winning a bet on interest rates. 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.
