The Spread Is the Story
The headline number most people track is the 30-year fixed, at 6.66% this week per Freddie Mac's survey. The number almost nobody tracks is the 15-year, which came in at 5.98% — back under six percent.
That 68 basis point gap is the one genuinely lower rate on offer in this market. It is not a forecast or a teaser. It is available today, to borrowers who can carry the payment.
The Payment Math on a Real Colorado Loan
Take a $500,000 loan, which is roughly what a buyer finances on a Denver-area detached home near the $660,000 median with 20% down. Principal and interest only:
- 30-year at 6.66%: about $3,210 per month
- 15-year at 5.98%: about $4,215 per month
That is roughly $1,000 a month more, before taxes, insurance, and any HOA. Colorado insurance premiums have climbed hard through the last two wildfire seasons, so the all-in difference in a mountain county can be wider still.
The lifetime interest difference runs into the hundreds of thousands of dollars. That number is real, and it is the reason the 15-year deserves a look. But it is earned by committing an extra $1,000 every month for fifteen years, with no option to stop.
Where the Savings Actually Come From
A common misread is that the 15-year saves money because the rate is lower. The rate is a minor contributor. The savings come almost entirely from time — you are borrowing the money for half as long. If you took the 30-year at 6.66% and simply paid it on a 15-year schedule, you would capture the large majority of the interest savings without ever signing up for a mandatory higher payment.
That distinction matters, because it reframes the decision. You are not choosing between saving money and not saving money. You are choosing between a required fast payoff at a discounted rate and a voluntary fast payoff at a slightly higher one.
Who the 15-Year Actually Fits
In our Colorado files, the borrowers who do well with it share most of these traits:
- Stable, comfortably sufficient income — the higher payment is a small share of take-home, not a stretch
- A long horizon in the property — selling in five years wastes most of the benefit
- Retirement accounts already funded — the extra $1,000 is not competing with a match you are leaving unclaimed
- A real emergency reserve — six months or more of expenses in liquid savings, not in home equity
- A payoff target — retirement, tuition, or a second-home purchase with a date attached
Who Should Skip It
- Self-employed and commission-based borrowers with lumpy income. The flexibility of the lower required payment is worth more than the rate discount.
- Anyone stretching to qualify. If the 15-year payment only works on paper, it does not work.
- Buyers who would drain reserves to do it. Home equity is the hardest asset to reach in an emergency, and reaching it usually requires qualifying for another loan at the exact moment you are least able to.
- Investors. On a DSCR or rental file, cash flow is the whole product. Cutting it by $1,000 a month to save future interest is usually backwards.
The Refinance Angle
If you bought in 2023 or 2024 at a rate in the 7s, a 15-year at 5.98% is worth pricing — you may be able to shorten the term and cut the rate at the same time, with a payment increase far smaller than the $1,000 in the example above. That is the one scenario where the 15-year is close to a free lunch, and it is worth ten minutes to check.
Run the break-even on closing costs before you commit. If you are not staying past it, the math does not work no matter how good the rate looks.
The Honest Read
The 15-year at 5.98% is a genuinely good rate and the wrong product for most people. The version of this strategy that fits nearly everyone is simpler: take the 30-year, keep the flexibility, and pay extra principal in the months you can. You will finish years early, and no bad month can turn your discipline into a delinquency.
