Two ranch homes sit across the street from each other in a west Oak Ridge subdivision. Same square footage, same builder, same year of construction. One parcel falls inside Anderson County. The other, because of a boundary that has nothing to do with the subdivision plat or the school zone, falls inside Roane County. Ask most buyers touring those two houses which county they're standing in and they'll shrug. They probably shouldn't, because it changes the tax bill they'll open every October.
That's the small version of a bigger problem. Buyers comparing Oak Ridge to Knoxville tend to stop at the list price. The real comparison lives one layer down, in the property tax rate each city and county actually charges, and that layer tells a story the price tag doesn't.
The sticker price isn't the surprise you think it is
Here's the part that catches people off guard first. Over the three months ending May 2026, Oak Ridge homes sold for a median price of $395,000, up 14.4% from the same period a year earlier. Over the three months ending June 2026, Knoxville homes sold for a median of $325,000, up a more modest 1.7% year over year. On a pure median sale price basis, Oak Ridge is currently trading higher than Knoxville, not lower.
Other data providers tell a slightly different version of this story depending on whether they're tracking a rolling home value index or actual closed sales, and the two markets have overlapped in price before. But no matter which snapshot you use, the gap between Oak Ridge and Knoxville home prices right now is nowhere near wide enough to assume Oak Ridge is automatically the budget option. That assumption is doing more work in most buyers' heads than the actual numbers support.
Then the tax rate does the opposite of what you'd expect
If the prices are close, the tax rates should be the tiebreaker in Oak Ridge's favor. They're not.
Tennessee assesses residential property at 25% of appraised value, then applies a combined rate per $100 of that assessed value. Run the two markets side by side and the gap widens in Knoxville's favor.
| Location | Combined city + county rate (per $100 assessed) | Assessed value on a $350K home | Estimated annual property tax |
|---|---|---|---|
| Oak Ridge, Anderson County side | $4.78 | $87,500 | approximately $4,183 |
| Oak Ridge, Roane County side | $4.7726 | $87,500 | approximately $4,176 |
| Knoxville, Knox County | $3.7096 | $87,500 | approximately $3,246 |
Those rates come from the City of Oak Ridge and Anderson County's own published figures, the Roane County rate published alongside them, and Knox County's official fiscal year 2025-2026 rate combined with the City of Knoxville's current municipal rate. Run the same math against the actual recent median sale prices instead of a flat $350,000, and the gap only gets more pronounced. On a $395,000 Oak Ridge home, the annual bill lands around $4,720. On a $325,000 Knoxville home, it lands around $3,014. That's roughly a $1,700 difference per year, or about $142 a month, before you've compared a single square foot of living space.
Put plainly, the Oak Ridge combined rate is not a rounding error above Knoxville's. It runs close to 29% higher.
Why one city has two different bills
The reason Oak Ridge has two slightly different combined rates instead of one comes down to geography most buyers never think to ask about. The City of Oak Ridge sits inside two Tennessee counties. Roughly 84% of the city's taxable parcels are in Anderson County, and the remaining 16% are in Roane County. Each county sets its own rate, and the City of Oak Ridge's municipal rate gets layered on top of whichever county rate applies to a given parcel.
The two combined rates land close to each other, so this isn't a case where one side of town is a bargain and the other isn't. But it does mean the specific parcel matters, not just the city name on the listing. A buyer under contract on an Oak Ridge home should confirm which county the parcel sits in before closing, both because the tax bill will come from that county's trustee office and because closing logistics, like where deed recording and title work happen, follow the county line too.
The rate that's about to move
Here's the part that makes the timing of this comparison matter right now, in August 2026. Knox County mailed countywide reappraisal notices in April and May 2026, and Property Assessor Phil Ballard reported that residential values had climbed by roughly 60% since the county's last reappraisal in 2022. Tennessee's certified tax rate law, sometimes called truth-in-taxation, requires the county to recalculate its rate downward after a reappraisal so that a jump in property values doesn't automatically hand local government a windfall in revenue. Ballard has publicly floated a new county rate near $1.00 per $100 of assessed value, down from the current $1.5540, and the Knox County Commission is expected to vote on the final certified rate this August.
This isn't a hypothetical mechanism. The City of Knoxville lived through a version of it in 2022, when the mayor proposed a 50-cent increase to the city's rate the same year a reappraisal was underway. Once the certified rate recalculation landed, the city's new rate actually dropped to $2.1556, the lowest it had been since 1974, even with the proposed increase folded in. Anderson County went through its own recalibration after a 2025 reappraisal too, which is part of why Oak Ridge's Anderson County side is sitting at $2.46 today rather than a higher pre-reappraisal figure.
If the Knox County Commission adopts something close to Ballard's $1.00 estimate this month, Knoxville's combined city and county rate would fall to roughly $3.16 per $100 assessed value, widening the gap with Oak Ridge even further. Nothing similar is on the table for Anderson or Roane County right now, so Oak Ridge's combined rate holds steady at $4.78, or $4.7726 on the Roane County side, no matter what Knox County decides this month.
What this actually means if you're weighing both markets
None of this means Oak Ridge is a bad move. It has genuine advantages, from The Preserve's marina and golf access to the walkable, mature streets around West Hills and Woodland. It means the price tag alone is the wrong number to compare.
If you're cross-shopping Oak Ridge and Knoxville, ask for the actual estimated annual property tax on each specific home, not just the county's average rate. A parcel's exact tax history is public record and your agent or the title company handling the transaction can pull it before you write an offer. Build that number into your monthly payment comparison the same way you'd build in insurance or HOA dues, because a $70,000 difference in list price can get erased by a few thousand dollars a year in property tax once you annualize it against a 30-year mortgage.
It's also worth watching for the Knox County Commission's certified rate vote this August. A meaningful drop in the county rate would change this comparison again, and buyers who lock in a purchase decision based on today's numbers without watching that outcome could be surprised either way.
A few questions worth asking before you write an offer
Does every Oak Ridge home pay the same property tax rate? No. Roughly 84% of parcels sit in Anderson County and pay a combined city and county rate of $4.78 per $100 assessed value. The remaining parcels sit in Roane County, where the combined rate is $4.7726. The difference between the two is small, but the county line itself affects where the deed gets recorded and which trustee's office sends the annual bill.
Is Knox County's property tax rate actually going to drop? Some drop is required by law once the reappraisal is final, since Tennessee's certified tax rate system prevents a county from collecting a windfall just because values went up. Knox County's assessor has publicly estimated the new rate will land near $1.00 per $100 of assessed value, down from today's $1.5540, with the county commission expected to vote on the exact figure this August.
If Oak Ridge and Knoxville home prices are this close, why does Oak Ridge get talked about as the cheaper option? That reputation is largely a legacy of past price gaps rather than the current market. Recent sale price data shows the two markets trading much closer together than the conventional wisdom suggests, and the tax rate difference actually tips the total monthly cost picture toward Knoxville, not Oak Ridge.
Numbers like these are exactly why a side-by-side price comparison only tells part of the story.
