The Tri-Cities’ top housing market tier continued to show strength and staying power last month. Eleven properties closed at or above $1 million, up from eight a year earlier.

September’s sales combined with the year-to-date data reflect both resilience in the luxury bracket and a widening geography of high-value demand. It’s no longer limited to a handful of marquee ZIP codes.

Last month, Washington Co. continued to set the pace in volume and stability while Sullivan delivered the headline-making deal and top sale of the year so far. Greene, Hawkins, and Carter are quietly emerging in the top-end market, with consistent luxury activity. Sales in the emerging countries are small in number but symbolic of how affluent buyers are spreading beyond the traditional core markets.

Top Sale

Last month’s top sale was Kingsport’s One Ridge Estate. It was a $2,950,000 cash deal for a seven-bedroom, seven-bath home that sits on 21.2 acres. It was on the market for 54 days.

The gated property includes a private rock quarry and a natural spring-fed steam. It has a multi-layered, 24/7 monitored security system, and craftsman architecture with a mix of formal and informal living areas, and a connected office that could also be a nursery. Also included is a fully furnished basement that includes a safe room, bathroom, recreation room, and a walk-out garage.

Outdoor accommodation includes a 16X40 ft heated saltwater pool and hot tub, and a circular driveway. The covered pool area includes a loft, rock-climbing wall, porch swings, and a dog run.

Luxury Market Matures

Last months and the year-to-date expansion of high-value demand across a wider footprint suggests that, even in a moderating housing cycle, the Tri-Cities’ top-end market has matured into a multi-county luxury ecosystem with solid footing heading into the final quarter of 2025

So far this year, Washington Co. continues to account for the largest share of million-plus closings, while Sullivan’s average sale price remains the highest among major counties. Greene and Carter are building consistent pipelines for upper-tier sales, and Hawkins and Johnson counties are beginning to appear on the radar of higher-end buyers.

Compared to last year, September’s results were clustered in fewer counties, but the price points were slightly higher on average. The 2025 shift shows a healthier mix with more participants across more localities. That suggests the luxury tier is broadening.

The record-setting cash sale underscores the ongoing preference for liquidity purchases at the upper end of the market. So far this year, 27 of the 66 sales have been cash deals.
