The Number: 6.66%, and It Is Up From Last Year
Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed at 6.66% for the week ending August 27, 2026 — up a single basis point from 6.65%. The 15-year fixed averaged 5.98%, up from 5.95%. Freddie Mac's own summary described rates as changing little.
The week-over-week move is noise. The year-over-year comparison is the story:
- 30-year fixed: 6.66% today vs. 6.56% in late August 2025 — up 10 basis points
- 15-year fixed: 5.98% today vs. 5.69% in late August 2025 — up 29 basis points
A buyer who stepped back last summer specifically to wait for a better rate has, twelve months later, a slightly worse one.
The Cost of the Year You Waited
Rate is only one line in the math, and usually not the biggest one. A buyer who paused in August 2025 also absorbed:
- Another year of rent — at Denver's typical rent, commonly $1,800 to $2,400 a month for a two-bedroom, that is roughly $22,000 to $29,000 paid to a landlord
- Another year of price movement — the metro median sits near $605,000, and detached homes near $660,000
- A year of principal not paid down — on a $500,000 loan, the first year retires roughly $5,000 to $6,000 of balance
Meanwhile the thing they were waiting on moved ten basis points the wrong way. On that same $500,000 loan, ten basis points is about $33 a month.
Why "Rates Will Fall Soon" Kept Being Wrong
Forecasts were not dishonest — they were built on an assumption that inflation would cool faster than it did. Mortgage rates price off the 10-year Treasury and mortgage-backed securities, and those markets have spent the year repricing how long higher inflation persists rather than how soon the Fed moves.
The practical takeaway is not that rates can never fall. It is that a rate forecast is not a plan. Twelve months of mid-6s pricing is long enough to treat this range as the current market rather than as an anomaly waiting to correct.
What This Changes for Colorado Buyers
Three adjustments worth making:
- Underwrite to today's number. Build your budget at 6.66%, not at the 5.5% you hope to refinance into. If the payment only works in the hoped-for scenario, the house is too expensive.
- Spend your energy where the dollars are. A $25,000 price concession moves a Colorado payment far more than a tenth of a point on the rate. In segments with real inventory — Denver attached homes are running near six months of supply — that concession is negotiable in a way the rate is not.
- Treat a future drop as upside, not as the plan. If rates fall meaningfully, refinancing is available. If they do not, you still own the home at a payment you already tested.
Where a Lower Rate Is Actually Available Right Now
The 15-year fixed is at 5.98% — 68 basis points below the 30-year. That is a real discount available today rather than a forecast. It costs a materially higher monthly payment, so it fits a narrower group: strong cash flow, a long time horizon in the property, and no competing use for the money. It is worth pricing rather than assuming.
The Honest Read
Nobody can tell you where rates go from here, and anyone who says otherwise is guessing. What the last year does say is that waiting is not free and not reliably rewarded. The buyers who did well in the last twelve months are the ones who built a budget around the actual rate, bought when the right property appeared, and kept refinancing as an option rather than a requirement.
