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

Marshall County presents a price-direction-versus-income-certainty tension: the Zillow county median home value was $143,081 in 2026-06, up 4.85% year over year, while FHFA’s repeat-transaction HPI for 2025 rose 12.27%. Both measures point upward, but they use different methods and labeled periods; neither is a closed-sale price for a specific asset, and their rates should not be averaged. This warrants investigation by operators able to verify property-level rent and carrying costs, while income-dependent buyers should be cautious.

02Housing economics

No county market asking rent is published, so gross yield cannot be computed. The $1,039 two-bedroom HUD FMR is a payment standard, not an estimate of market rent, and cannot fill that gap. Carrying costs are material to price underwriting: the effective property-tax rate is 1.94%, with a $2,766 median annual tax. Those county figures do not establish a subject property’s assessment, insurance, repairs, utilities, vacancy, or operating expenses; without those inputs, the relationship between acquisition price and net cash flow remains untested.

03Demand & competition

County workplace evidence is constructive but concentrated. QCEW reports 2,862 annual average covered jobs, rising 3.51%. Manufacturing, the largest disclosed private supersector, accounts for 33.61% of private covered employment; this is not a measure of all county employment or resident labor conditions. Migration shows a net loss of 49 tax-return households, although inbound movers’ average income exceeded outbound movers’ by $7,068. That mix calls for tenant and buyer segmentation rather than assuming the income gap offsets household loss. Investor participation was 8.61% of purchase mortgages to non-occupants, a limited county-level marker of buyer competition rather than evidence of rental demand.

04Risk & next checks

Inland flood is the dominant hazard, and modeled annual climate loss equals 0.13% of building value. This is a modeled ratio, not a dollar loss or a property-specific flood determination; underwriters need parcel flood status, insurance quotes, deductible terms and loss history. Realtor.com MLS listing price, active-listing, days-on-market, reductions and pending metrics are not published in this record, preventing a read on visible supply, seller concessions and marketing time. Also absent are market rent, vacancy, lease-up, closed-sale comparables and financing terms, so neither yield nor exit liquidity can be underwritten from county evidence alone.

No rent index is published for this county.Zillow’s county rent series does not cover every county, and estimating one from a neighbouring county would be a guess wearing a number’s clothes. Everything above is measured here; for a rent figure, the Peoria, IL page covers the wider market.

Bear case

What can break the county thesis

  1. Unpublished market rent, vacancy and operating costs could overturn any cash-flow conclusion.
  2. Inland-flood exposure and insurance costs may vary materially by parcel despite the county modeled-loss ratio.
  3. Household out-migration and manufacturing concentration could weaken depth in a specific tenant or resale segment.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. County market asking rent is not published, and HUD FMR cannot be substituted for market rent.

Do the Zillow and FHFA measures describe the same price change?

No. Zillow provides a county home-value observation, while FHFA is a repeat-transaction index; their supplied periods and methods differ.

What is the largest disclosed private employment sector?

Manufacturing is the largest disclosed private supersector by covered employment.
