Whether you're thinking about buying, selling, or simply tracking your home's value, staying current on market conditions is one of the smartest things you can do. This update covers national mortgage rates and housing supply—and what it means for buyers and sellers here on the Treasure Coast.
What's Happening with Mortgage Rates
The 30-year fixed-rate mortgage averaged 6.76% for the week ending September 10, 2026, up from 6.71% the prior week and well above 6.35% a year ago. The 15-year fixed averaged 6.09%, up from 6.04%. Freddie Mac's chief economist Sam Khater continues to advise buyers to shop around and compare quotes from multiple lenders, noting it can save thousands over the life of a loan.
The Fed held rates steady at its July 29 meeting. The next decision lands September 15–16, 2026 — worth watching, since any move (or signal of one) will likely ripple into mortgage pricing within days.
For Treasure Coast buyers, rate relief still isn't guaranteed in the near term. Buyers financing a purchase should be working closely with a lender now to explore rate locks, two-one buydown programs, and whether an adjustable-rate mortgage makes sense for their timeline. Waiting for rates to drop may mean competing in a more active market when they do.
National Housing Supply
Nationally, existing home sales slipped to a seasonally adjusted annual rate of 3.98 million in August 2026 — down 2% from July and 1.2% below a year ago, the first sub-4-million reading since June 2025. Total inventory rose to 1.62 million units (up 3.2% month-over-month, 5.9% year-over-year), pushing months of supply to 4.9 — the highest level in more than a decade. The national median existing-home price was $429,100, up 1.6% year-over-year and the 38th straight month of annual price gains, even as 42.1% of listings carried at least one price reduction — above the normal 30–35% range.
The broader picture remains a market finding its footing in a persistently high-rate environment — with enough activity to keep values supported, but enough hesitation, and now enough inventory, to give prepared buyers real negotiating room.
What This Means for Treasure Coast Buyers
National inventory just hit its highest level in over a decade, and longer days on market in some pockets have handed buyers more leverage than they've had since before 2021. You have time to look carefully, negotiate on price and terms, and avoid the panic-offer dynamics of the last few years.
That said, the Treasure Coast is not a distressed market. Martin County inventory is down sharply year over year — active listings fell 20% to 1,210 — keeping values well supported even as national conditions loosen. The opportunity is real, but so is the competition for the best properties.
If you're pre-approved and ready to move, this may be one of the better entry windows the Treasure Coast has offered in several years.
What This Means for Treasure Coast Sellers
Pricing discipline is everything right now. Nationally, over 42% of listings have taken a price cut — a reminder that buyers everywhere, including here, are pushing back on ambitious pricing. The sellers doing best price accurately based on recent comparable sales, prepare the home carefully, and work with an agent who has genuine marketing reach beyond the MLS.
The good news: Martin County's inventory compression still works in sellers' favor, and momentum is improving—single-family homes are going under contract in a median of 43 days, down from 50 days a year ago. Fewer competing listings mean your well-prepared, well-priced home has a real audience.
