A home search in Colonial Heights turns up a pattern fast. Listings run around $112 a square foot, well under the roughly $156 a square foot that Kingsport sales have been closing at citywide. On paper, that reads like a discount. Same commute, same grocery stores, same interstate access, just a lower price per square foot.
The tax bill does not agree with that story, and neither does the history of how this particular patch of Kingsport got built.
A City Address With a County Habit
Colonial Heights is a census-designated place inside Sullivan County that the City of Kingsport formally annexed in 1988. That is not ancient history by municipal standards. Plenty of the homes on the market today were already built before the neighborhood carried a Kingsport address at all.
Annexation here was not a single clean line drawn on a map. Kingsport's Regional Planning Commission kept pulling in additional Colonial Heights properties for years afterward, small parcels rather than sweeping ones. City records show pieces like the Eagle Pointe condominiums on Sir Echo Drive, just under three acres and roughly 95 residents, coming into the city on their own separate vote, alongside similar additions like Ashley Oaks condominiums and the Remington House assisted-living facility. The city's logic each time was consistent: annex what's already on water and sewer, and take the rest later.
That rolling process explains a detail that surprises buyers who assume "in the city" means fully caught up. By at least one national classification system that measures population density, Colonial Heights still reads as a rural neighborhood rather than a suburban one, even though it has sat inside Kingsport's city limits for close to four decades.
What the City Actually Built Here
An address change on a map is not the same as a finished utility system underneath it, and Kingsport's own project history shows the gap between the two.
City engineering releases document an 18-month stretch of water, sewer, stormwater, and road work concentrated specifically in the Colonial Heights annexation area, with named work zones including:
- Moreland Drive, near its intersections with Shadyside Drive and Nickleby Court
- Sanitary sewer installation on Moreland Drive
- Utility work behind the apartments off Kendrick Creek Road, near Tiffany Court
Separately, the city's own facts-and-stats accounting for the broader annexation era lists a $10.8 million sewer line installation project tied directly to the Colonial Heights annexation area, plus $847,000 spent paving roads there and another $750,000 to install hydrants and upgrade waterlines. Those are not small maintenance line items. They are the kind of infrastructure bill a neighborhood runs up when it spends decades outside a city's utility footprint and then joins it.
This is not purely a history lesson. In April 2026, Kingsport crews set up emergency water distribution in Colonial Heights following a water main break, the kind of event that shows up when a system built in phases over multiple decades still has seams. The utility build-out that started with 1988 annexation is not a closed chapter.
The Zip Code With the Highest Tax Bill in Town
Here is where the "cheaper" story runs into trouble. Property tax analysis of the Kingsport area shows the 37663 zip code, which covers Colonial Heights, carrying the highest median tax bill of any zip code tracked in the Kingsport market, ahead of every other zip in the comparison set. That is not what you would predict from a neighborhood pricing under the city's per-square-foot average.
The mechanics are straightforward even if the outcome feels backward. Property tax bills follow assessed value and local levy rates, not list-price psychology. A lower price per square foot on a listing sheet does not automatically translate to a lower carrying cost once the county and city both take their share, and Colonial Heights currently sits on the wrong side of that math relative to its neighbors.
The 24% Increase Nobody in Colonial Heights Got to Skip
Layer the city's most recent budget cycle on top of that, and the timing looks worse for anyone banking on Colonial Heights staying the budget-friendly option.
Kingsport's fiscal year 2026 budget, which took effect July 1, 2025, raised city property taxes by roughly 24 percent. The Board of Mayor and Aldermen set the new city rate for the Sullivan County portion of Kingsport, which covers Colonial Heights, at $1.6773 per $100 of assessed value, about 33 cents higher than the certified equalized rate of $1.34 that would have kept revenue flat. For context on scale, city officials cited a home assessed at $300,000 seeing its city tax bill move from $979 to $1,218 under the new rate.
City Manager Chris McCartt framed the broader capital backlog behind that decision in blunt terms:
"Since 2017, we have been in a catch-up mode, trying to get paving back in line."
That is the same phrase that fits Colonial Heights specifically, just applied citywide. The rate increase did not carve out an exception for annexed neighborhoods still finishing their utility build-out. Colonial Heights paid the new rate exactly like the rest of Kingsport, on top of whatever local infrastructure costs already got baked into decades of catch-up spending.
What This Means If You're Comparing Colonial Heights to Somewhere Else
None of this makes Colonial Heights a bad option. It makes the sticker price a partial answer. A buyer comparing a Colonial Heights listing against a comparable one elsewhere in Kingsport needs the total monthly number, not just the per-square-foot line, before deciding which one actually costs less to hold.
A few questions worth asking before writing an offer:
What is the property's current assessed value, not just its list price? Sullivan County assessment notices go out each spring, and the assessed figure, not the asking price, is what a city rate like the $1.6773 per $100 set for fiscal year 2026 actually multiplies against.
Is the home on city water and sewer, or still running on a system installed before full annexation? Given the documented history of phased utility work in this specific area, that is not a rhetorical question here the way it might be in a neighborhood with a longer, uninterrupted service history.
How does the total tax-plus-utility number compare to a similarly priced home in a different Kingsport zip code? The 37663 tax pattern suggests that comparison can flip the "which house is actually cheaper" answer.
None of these are deal breakers. They are the kind of due diligence that turns a portal search into an actual decision, and they matter more in a neighborhood whose city status is newer than its housing stock.
A Couple of Straight Answers
Is Colonial Heights part of the City of Kingsport? Yes. It has been since a 1988 annexation, with additional smaller parcels added incrementally in the years since.
Does a lower price per square foot in Colonial Heights mean a lower total cost of ownership? Not automatically. Tax bill data for the 37663 zip code shows the opposite pattern, and the citywide rate increase that took effect for fiscal year 2026 applied to Colonial Heights the same as anywhere else in Kingsport.
If you're weighing Colonial Heights against another Tri-Cities neighborhood, the honest comparison runs through assessed value and utility history, not just the price tag on a listing sheet.
