Two homes go under contract in Centennial the same week, ten minutes apart, both priced right around $650,000. The buyers compare notes at a barbecue eventually, the way people do, and discover their property tax bills aren't close. Same city seal on the welcome sign. Same zip code range. Different number showing up every January.
That's not a fluke of assessment timing. It's a boundary line that runs through the middle of Centennial and shows up nowhere on a listing photo, a portal's price card, or the city's own welcome page. It's the line between Cherry Creek School District and Littleton Public Schools, and right now, for reasons tied to a school board vote three weeks ago, that line is about to matter more than it has in years.
Centennial is young as Colorado cities go. It incorporated in February 2001, stitched together from unincorporated pieces of Arapahoe County that already had names of their own, the old Castlewood and Southglenn areas among them. That history matters because Centennial never got the chance to draw its own school district. It inherited whatever lines already existed on the county map, and those lines split the new city in two.
Most of Centennial sits inside Cherry Creek School District's territory. The western and southwestern slice, roughly along the Santa Fe Drive and Broadway corridor, falls inside Littleton Public Schools instead. Both districts are well regarded and both have run competitive, well-attended bond and override campaigns in recent years. That's not the story here. The story is that each district is its own taxing authority, and each one certifies its own mill levy to Arapahoe County independent of the other. A home inside the Cherry Creek boundary and a home inside the Littleton Public Schools boundary can sit a few blocks apart, list for the same price, and still carry two different tax stacks for the life of the mortgage.
The gap between those two tax stacks isn't static. It moves every time one district passes a bond or an override and the other doesn't, and this year the two districts are moving in opposite directions at very different speeds.
| Cherry Creek School District | Littleton Public Schools | |
|---|---|---|
| Most recent major measure | November 2024: $9 million mill levy increase plus a $950 million bond issue | August 13, 2026: board voted to refer a mill levy override to the November 2026 ballot |
| Stated reason | Safety upgrades, building replacement at three of the district's oldest campuses, deferred maintenance exceeding $300 million | A $10.6 million budget deficit tied to state funding formula changes and declining enrollment |
| Estimated homeowner cost | Under $15 a month for a $500,000 Arapahoe County home, per district officials | Not yet set. Voters decide November 3. Running the election through the county is projected to cost the district about $82,000 |
| Where it stands | Passed and already being collected | Pending, on the ballot this November |
Littleton Public Schools Superintendent Todd Lambert has been candid about what happens if voters say no. Without new revenue, the alternative on the table has been a wage freeze and a districtwide furlough day rather than a cost-of-living increase for staff. The board's Chief Financial Officer, Jonathan Levesque, told the board plainly that the district needs to "grow revenue to match expenditures, even reduced expenditures." That's not abstract budget language. It's a district telling its own residents, in a public meeting on August 13, that its funding model is strained enough to change how it operates unless the November ballot measure passes.
Cherry Creek isn't standing still either, even without a fresh measure on this year's ballot. The district has been explicit that rising local property values don't automatically translate into more district revenue, because Colorado's school finance formula reduces the state's contribution whenever local assessments climb. A homeowner on the Cherry Creek side of Centennial is paying into a levy structure that's already locked in from 2024. A homeowner on the Littleton Public Schools side is watching a new one get decided at the ballot box this fall.
If the LPS measure passes, the effective tax gap between the two sides of Centennial narrows. If it fails, the gap that already exists holds, and the pressure Lambert described publicly doesn't go away. Either way, the two halves of this one city are no longer moving on the same timeline, and a buyer who treats "Centennial" as a single tax environment is pricing against an assumption that stopped being true the moment the board voted.
Here's where the boundary problem compounds into a pricing problem. Pull up five different market reports for Centennial right now and you will get five different medians, and the spread isn't a rounding error.
As of late July 2026, one widely used home value index put Centennial's average home value at $641,069, down 1.8% over the prior year. A separate market tracker listed the August 2026 median list price at $650,000, down 6% from both the prior month and the same month a year earlier. A third source's citywide page showed a February 2026 median sale price of $666,000, up 9% year over year, while that same platform's narrower neighborhood-level page for the Littleton side of Centennial showed a May 2026 median of just $539,000, up nearly 20% year over year. A fourth tracker had the 30-day trailing median at $650,000, up 9.2%.
Line those numbers up and the spread runs well past $125,000, all supposedly describing the same city in the same rough window of 2026. None of that is fraud or bad math. It's a symptom of the same boundary problem driving the tax question. "Centennial" as a search term on a national portal and "Centennial" as a taxing and school-assignment geography are not the same shape. Some of these figures are pulling from a wider citywide dataset that blends both district territories together. At least one is isolating a narrower slice on the Littleton Public Schools side of the boundary, where price points and inventory run differently than they do on the Cherry Creek side. A citywide median that blends two administratively different halves of a city is a statistic you can quote at a dinner party. It's not one you should underwrite an offer against.
If you're cross-shopping Centennial against Highlands Ranch, Parker, or another South Metro suburb, the citywide median is the least useful number in the comparison. Before you put weight on it, confirm three things for the specific address you're considering:
None of this is a judgment about which side of Centennial is the better buy. It's a reminder that a city assembled from someone else's boundaries in 2001 never fully smoothed those seams out, and this particular November is the moment they're showing again.
Is Centennial split between two counties as well as two school districts? No. The entire city sits within Arapahoe County. The school district split, between Cherry Creek and Littleton Public Schools, is a separate boundary layered on top of a single county government.
If the Littleton Public Schools override passes in November, does my tax bill change right away? Mill levy overrides approved at a November election typically begin affecting the property tax bill collected the following year, not immediately. The specific dollar impact for the LPS measure had not been finalized as of the board's August 13 vote, since that detail is part of what will appear on the ballot.
Does being on the Cherry Creek side versus the Littleton Public Schools side affect how a home is valued by appraisers or portals? Public data sources track these areas differently, which is part of why citywide medians and neighborhood-level medians for Centennial diverge so widely right now. Neither boundary side is being described here as a better or worse investment. The point is that they are different administrative environments with different tax certifications, and that's a due diligence item, not a quality ranking.
