Do two methods point the same way?

Zillow estimates a current home value. FHFA tracks repeat mortgage transactions. Their growth rates should be read side by side, not averaged.

County brief

What the local evidence says

01Decision frame

Unicoi County presents a carry-versus-liquidity tension: Zillow’s county 2026-06 median home value is $251,230, up 4.84% year over year, against measured median asking rent of $1,148 per month and a published 5.48% gross yield before costs. Buyers able to validate unit expenses and rents should investigate; those dependent on quick resale or narrow margins should be cautious. FHFA’s 2025 repeat-transaction HPI rose 5.44% year over year. Both point to positive price movement, but FHFA is an index, not a home value, and has a different method and period from Zillow.

02Housing economics

Housing economics remain incomplete. HUD’s two-bedroom Fair Market Rent is $1,132 per month, a payment standard rather than a market asking-rent estimate, so it should not replace measured rent in yield work. The effective property-tax rate is 0.52%; underwriters should apply it to the specific assessment and test insurance, maintenance, vacancy, financing and utilities. Those operating inputs and property-level tax assessments are not published, preventing a net-cash-flow conclusion. Neither Zillow’s value observation nor FHFA’s HPI establishes a closing price.

03Demand & competition

In Realtor.com’s 2026-06 MLS listing market, active listings increased 38.89% and 23.11% of listings had price reductions. Together, supply growth and concessions warrant pricing review, although active listings are supply, reductions are seller concessions, and neither proves buyer demand or a closed-sale price. Tax-return migration was positive by 160 households, with inbound movers’ average income $15,829 above outbound movers’; these are moving-tax-return measures, not renter demand. Fourteen investor purchases among 175 purchases represent an 8% observed non-owner share rather than total investor activity.

04Risk & next checks

Risk limits need parcel-level testing. Inland flood is the dominant hazard, and modeled annual building-value loss is 0.13%; this county-level expectation does not identify parcel exposure, insurance terms or deductibles. QCEW’s 2025 annual average covers jobs at county workplaces, not resident employment or unemployment. Covered employment declined year over year, and Manufacturing was the largest disclosed private supersector, requiring concentration diligence. Next checks: flood zone and loss history, insurance quotes, rent comparables, assessed tax and closed-sale comparables. Vacancy, expenses, financing and parcel-condition evidence are not published, preventing a property-level return or resale conclusion.

Bear case

What can break the county thesis

  1. Parcel-level flood exposure, insurance cost or deductibles may exceed the county-level hazard framing.
  2. Unreported vacancy, maintenance, financing and assessment outcomes may erase gross-yield support.
  3. MLS supply growth and seller concessions may make resale pricing or lease-up weaker than county measures suggest.
Underwriting questions

Before pricing a property

Can a net cash-flow return be calculated from this record?

No. Market rent and gross yield are published, but operating expenses, vacancy, financing and property-level tax assessment data are not published.

Does HUD Fair Market Rent establish the county’s asking rent?

No. It is a two-bedroom payment standard; measured median asking rent is separately published.

What does the QCEW labor series measure?

Annual average covered jobs at workplaces in the county, not resident employment or unemployment.
