Home / Colorado / Arapahoe County
Arapahoe County's sending new property values around May 1, 2027, and they'll be based on what homes sold for between July 2024 and June 2026, so most of that evidence is already in. We've looked at 15,035 of those sales, and the typical home sold for 0.7 percent below the value it carries now. 53 percent sold for less.
Honestly, it looks a lot more like Denver than like Jefferson County. Houses are about level, with the typical one selling for 0.6 percent above its value, but townhomes and other attached homes are down, at 4.0 percent below their value, and 68 percent of them sold for less. And 2026 sales alone ran 1.7 percent below the current values.
So for a lot of Arapahoe homes, the 2027 value may come in flat or even a bit lower. But when about half of homes sell below their current value, the county's model can easily leave some of them too high, and that's where a protest can really work.
That's what our free check's for. Once the notices are out in May 2027, it'll compare your new value with what genuinely similar homes near you actually sold for, matching the county's own neighborhood and quality grade, and tell you straight whether you'd have a case. Most people who use it get told not to bother, and we'd rather you heard that first.

So here's how it works. Your notice of value should arrive around May 1, 2027, and you'll protest to the Arapahoe County Assessor by June 8. It's free, and it's pretty quick to do. The assessor's got to answer by the last working day of June, and if you still don't agree, you can appeal to the County Board of Equalization by July 15, which doesn't cost anything either.
Now the question in a Colorado protest is what your home was worth on June 30, 2026. So the evidence that really counts is sales of genuinely similar homes nearby from the two years before that date, and what homes sell for later doesn't help much. You don't need a lawyer for any of it, honestly.
Here's how sales compare with current values in each town. It runs from about 30 percent of homes selling below their value in Cherry Hills Village to 60 percent in Aurora, so the towns really aren't moving together.
| Town | Sales | Typical sale vs. current value | Sold below |
|---|---|---|---|
| Aurora | 9,000 | -1.8% | 60% |
| Centennial | 2,635 | +3.3% | 36% |
| Englewood | 1,275 | -0.1% | 50% |
| Littleton | 1,173 | -0.4% | 52% |
| Greenwood Village | 321 | +2.0% | 40% |
| Cherry Hills Village | 132 | +4.5% | 30% |
Basically, Colorado taxes a home in two parts. From 2026, the city and other local districts tax 6.8 percent of your value after they've taken 10 percent off it, up to $70,000, and the schools tax 7.05 percent of the full value. Arapahoe's rates vary a lot from one tax area to the next, and we haven't been able to check the county's own table yet, so we're not going to guess at a dollar figure here. Your tax bill shows your area's rate.
Also, if you're 65 or older and have owned and lived in your home for at least 10 years, Colorado's senior homestead exemption takes 50 percent off the first $200,000 of its value. You'll apply with the Arapahoe County Assessor by July 15. The state only funds it when its budget allows, so it's really worth checking whether it's being paid this year.
Just so you know, the sales comparison's our own, read from Arapahoe County's public parcel records on 2026-10-08. We've counted every sale from July 1, 2024 to June 30, 2026 that the county marks as a qualified sale, for houses and attached homes built before 2024, for $50,000 or more, and compared each price with the home's current value, which is basically the market as of June 30, 2024. Sales the county codes another way, like family transfers and foreclosures, aren't counted, because they don't really tell you what a home's worth. We've also left out the odd sale that's under half or over two and a half times the value. The town's the city in the home's address, so it probably includes some unincorporated homes too, and we only show a town that's got at least 100 sales.
And the protest steps are Colorado law, so they're the same in every county. The tax arithmetic's from House Bill 24B-1001.
