Cost of Living & Housing in Signal Mountain
Signal Mountain is a genuinely more expensive small town than most of this dataset's other Tennessee Tier C markets -- a real reflection of its affluent, low-density, top-school-district character -- though its town-level property tax rate has held flat for four straight years and Tennessee levies no state income tax.

Sources disagree meaningfully on the exact current figure, disclosed here rather than resolved: Redfin's most recent monthly reading showed a $588,000 median SALE price, down a real 19.8% year over year -- likely small-sample volatility in a town of under 9,000 residents rather than a genuine market correction. Zillow's separate home-VALUE estimate ran $626,617 (up 1.8% over the past year), with a $712,333 median LIST price as of April 2026, and other sources cited listing prices as high as $864,000. Whichever figure is used, Signal Mountain runs genuinely, substantially more expensive than Greeneville or Elizabethton, this dataset's other East/Southeast Tennessee Tier C markets.
Property Taxes -- A Flat, Modest Town Rate
The Town of Signal Mountain's FY2026 property tax rate is $1.1002 per $100 of assessed value, unchanged for the 4th straight year (down from $1.70 per $100 in an earlier prior year). Signal Mountain residents owe both Town and Hamilton County tax. Ownwell separately cites a median effective property tax rate of 0.56% -- below both the 1.02% national median and the 0.64% Tennessee state median, a real, favorable contrast to the elevated housing PRICES themselves. Tennessee's standard 25% residential assessment ratio applies statewide.
Sales Tax and No State Income Tax
Tennessee levies no state income tax at all. Hamilton County's combined sales tax runs 9.25% (7% state + 2.25% county) -- notably lower than the 9.75% maximum-local-option rate cited for several other Tier C East Tennessee markets in this same build wave, though still consistent with Tennessee's overall high-sales-tax statewide pattern.
Income and Overall Cost of Living -- A Real, Disclosed Mixed Picture
Median household income is cited at $141,008, with a poverty rate of just 3.31% -- real, sourced markers of genuine local affluence. On overall cost of living, sources genuinely contradict each other: one reading describes Signal Mountain as 16% more expensive than the national average overall (with housing specifically 56% above national), while a separate reading from a similar aggregator family describes housing as 21.2% BELOW the national average. This contradiction was not reconciled this session -- the housing-price figures above are the more directly verifiable indicator of Signal Mountain's real cost premium.
Key takeaways
- Housing runs genuinely expensive by every cited figure ($588K-$864K depending on source and measure) -- meaningfully more than most other Tennessee Tier C markets in this dataset, even though sources disagree on the exact number.
- The Town's property tax rate ($1.1002/$100, unchanged for 4 straight years) computes to a cited 0.56% effective rate, below both the national and Tennessee state medians -- a real contrast with the elevated home prices themselves.
- No state income tax statewide; Hamilton County's 9.25% combined sales tax runs somewhat lower than several other East Tennessee Tier C markets in this dataset, though still high by national standards.
- Median household income ($141,008) and a 3.31% poverty rate reflect genuine local affluence -- but cost-of-living aggregators genuinely disagree on whether Signal Mountain runs above or below the national average overall, a real, disclosed contradiction not resolved this session.
