What a 15 Year Mortgage Refinance in Broomfield, CO Changes
A 15 year mortgage refinance in Broomfield, CO replaces the loan you have with one that is paid off in 180 monthly payments instead of whatever is left on your current schedule. The rate may change too, but the term is the point. You are trading a higher monthly payment for a shorter, cheaper path to owning the home outright.
Here is the number that tends to stop people. At the same interest rate, a 15-year loan charges roughly half the total interest of a 30-year loan, or less. That holds at any rate, and the gap widens as rates rise. In practice, 15-year loans also tend to price lower than 30-year loans, so the real difference is usually larger.
This guide walks through the numbers I lay out for Broomfield homeowners at my office at 8181 Arista Place. It sticks to figures that do not depend on today's rate: payment counts, pricing rules, mortgage insurance tiers, and local data. I will not quote rates here, because yours depend on your credit, equity, and the day you lock.
The Broomfield Numbers Behind a 15-Year Refinance
Broomfield County has about 20,177 owner-occupied homes, according to the Census Bureau's 2024 American Community Survey. Roughly 68 percent of them still carry a mortgage. Those are the households for whom a 15 year mortgage refinance in Broomfield, CO is a live question.
The same survey shows when those owners moved in. Move-in year is not the same as loan date, since many owners refinanced in 2020 and 2021. Still, it is a fair guide to how far into a loan most Broomfield owners are.
| Owner Moved In | Broomfield County Owners | Share of Owners |
|---|---|---|
| 2023 or later | About 1,200 | 6% |
| 2020 to 2022 | About 3,100 | 15% |
| 2010 to 2019 | About 8,950 | 44% |
| Before 2010 | About 6,900 | 34% |

In plain terms, the largest group of Broomfield owners settled in during the 2010s. Many of them are now somewhere between year 7 and year 16 of a 30-year schedule. That is exactly the stretch where a 15 year mortgage refinance in Broomfield, CO either shortens the loan meaningfully or barely moves it, so it pays to know where you sit.
Age matters too. About 24 percent of Broomfield owner households are headed by someone aged 55 to 64, and another 23 percent by someone aged 45 to 54. For many of those households, the appeal is simple: a 15-year loan can be gone before retirement.
How Many Years a 15-Year Refinance Takes Off
This is the most useful table I share, and it needs no rate at all. It compares the payments left on an original 30-year loan with the 180 payments on a new 15-year loan.
| Years Into a 30-Year Loan | Payments Left Now | Payments on a New 15-Year | Time Taken Off |
|---|---|---|---|
| 1 year | 348 | 180 | 14 years |
| 3 years | 324 | 180 | 12 years |
| 5 years | 300 | 180 | 10 years |
| 7 years | 276 | 180 | 8 years |
| 10 years | 240 | 180 | 5 years |
| 13 years | 204 | 180 | 2 years |
| 15 years or more | 180 or fewer | 180 | None, it adds time |
Assumes the original loan was a 30-year loan paid on schedule, with no extra principal payments.
Read it this way. Early in a loan, a 15 year mortgage refinance in Broomfield, CO takes a decade or more off your payoff date. By year 13, it only saves about two years, and the closing costs may outweigh that. Past year 15, a new 15-year loan would actually push your payoff date later. At that point, extra payments on the loan you have usually make more sense.
A 15-Year vs. 30-Year Refinance in Broomfield, CO, Side by Side
Beyond the payoff date, a few published rules treat 15-year loans differently. Each one changes your cost in a way a rate quote alone will not show. The table compares a 15 year mortgage refinance in Broomfield, CO with a new 30-year refinance.
| What Changes | New 30-Year Loan | New 15-Year Loan |
|---|---|---|
| Monthly payments | 360 | 180 |
| Payment at the same rate | The baseline | Higher, but always less than double |
| Total interest at the same rate | The baseline | Roughly half or less |
| Fannie Mae credit score and equity price grid on a rate-and-term refinance | Applies | Does not apply |
| Standard mortgage insurance coverage, 85.01% to 90% of value | 25% | 12% |
| FHA annual mortgage insurance, loan of $726,200 or less, 90% of value or less | 0.50% a year | 0.15% a year |

The Pricing Rule Most People Never Hear About
Fannie Mae charges lenders upfront pricing adjustments based on your credit score and how much equity you have. Lenders pass those costs through in your rate or fees. On a rate-and-term refinance, Fannie Mae's price matrix applies that score and equity grid only to loans with terms longer than 15 years.
So a 15-year rate-and-term refinance skips the biggest pricing table entirely. That matters most if your score is below the top tier or you have less than about 30 percent equity. However, the grid for cash-out refinances applies to every term. Other add-ons, such as those for condos, also apply to every term. If you are unsure which kind of refinance you would be doing, my rate-and-term refinance guide explains where Fannie Mae draws that line.
Mortgage Insurance Gets Lighter on Shorter Terms
If you have less than 20 percent equity, a conventional refinance needs mortgage insurance. Fannie Mae's coverage rules set lower standard coverage for fixed-rate loans of 20 years or less. Lower coverage generally means a lower premium. My guide to removing PMI covers how that insurance comes off later.
FHA works the same way, only more sharply. Under HUD's current premium table, a 15-year FHA loan of $726,200 or less with at least 10 percent equity carries an annual premium of 0.15 percent for 11 years. The same loan on a longer term carries 0.50 percent. The upfront premium is 1.75 percent of the base loan either way.
