Tri-Cities mobile home sales are holding their own in 2025. Through September, 401 units closed, 3% fewer than the 414 closings during the same period in 2024.

The median sale price climbed to $210,000, up 5%, and the average pushed to $211,582 – a $8,500 gain from last year.

That modest price rise amid a near-flat sales count is the definition of steady demand.

Buyers continue to chase affordability, but replacement-cost pressures and limited listings keep values from slipping.

So far, the market is on pace to end just below last year’s sales volume but above it in price.

Short-term headwinds (rate lock-in, credit tightening) will probably moderate turnover, but long-term affordability fundamentals remain solid, particularly in Greene and Washington counties where land access, zoning flexibility, and infrastructure favor continued absorption.

September snapshot

48 sales region-wide | Median Price $215,000

Sales were evenly distributed across the region, with Greene (16) and Washington (14) counties anchoring the month’s total.

• Greene County’s median came in at $224,950, a close mirror of its 2025 YTD median.
• Washington posted the month’s highest median at $235,600, signaling continued upward momentum for newer-model units and improved land packages.
• Sullivan (9 sales, median $175,000) and Hawkins (4 sales, median $233,500) rounded out the active counties.

While September sales volume dipped slightly compared with midsummer levels, pricing stability shows that demand is firm even as buyers absorb higher financing costs.
