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

Union County presents an appreciation-versus-cash-flow tension. Zillow’s median home value is $164,334, up 5.39% in June 2026, while FHFA’s repeat-transaction HPI rose 11% in annual 2025 data and 41.40% cumulatively over five years. These are different measures and vintages, not a blended growth rate or home value. The positive price signal merits property-level investigation by an appreciation-oriented buyer; a cash-flow buyer should be cautious because market rent is not published and gross yield cannot be computed.

02Housing economics

HUD’s two-bedroom FMR is $919 per month, but it is a payment standard rather than asking rent and cannot substitute for market rent. That missing measure blocks a rent-to-price test and any gross-yield calculation. The effective property-tax rate is 1.80%, with median annual tax of $2,197. Against the stated price, taxes belong in carrying-cost underwriting, but insurance, maintenance, vacancy, financing and property-level tax detail are not supplied. Thus, price appreciation is not evidence of acceptable operating cash flow.

03Demand & competition

Realtor.com MLS evidence shows median listing-price growth of 19.80%, with active listings and marketing time providing context rather than closed-sale proof; a price-reduced share and pending ratio likewise do not establish buyer demand. QCEW reports 5,817 annual covered jobs, down 1.57%, while the average covered-worker wage is $1,004 per week, up 4.37%. Manufacturing is the largest disclosed private supersector, so the wage base has a disclosed concentration and is not the whole economy. Tax-return migration was slightly negative, and incoming movers had lower average AGI than outgoing movers. Investor purchases were a small minority of total purchases, so recorded investor competition appears limited, but that does not resolve overall demand.

04Risk & next checks

Underwriting should next obtain a market-rent set, closed-sale comparables, property-level taxes, insurance quotes and flood-zone or elevation information. Inland flood is the dominant hazard, while the modeled building-loss ratio is 0.11% annually; that modeled figure is not a property-specific insurance or repair budget. Also verify the subject’s condition, utilities, financing terms, vacancy assumptions and employment exposure before treating the price signal as investable. The record cannot establish net operating income, debt coverage, resale liquidity or hazard-adjusted returns, so those conclusions remain open.

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; no wider market is mapped for it either.
Bear case

What can break the county thesis

  1. Absent market rent prevents reliable cash-flow, yield and rent-to-price underwriting
  2. Shrinking covered employment and negative migration leave tenant and resale demand insufficiently established
  3. Inland-flood exposure and missing property-level insurance and flood information could make modeled loss evidence unusable for actual costs
Underwriting questions

Before pricing a property

Is market rent published, and can gross yield be calculated?

No. Market rent is not published; the HUD two-bedroom FMR is a payment standard, not market rent, so gross yield cannot be computed.

What does the FHFA figure measure?

It is a repeat-transaction home-price index, not a dollar home value, and its annual observation is a different vintage from Zillow’s county observation.

Which private supersector is largest among those disclosed?

Manufacturing is the largest disclosed private supersector in the record.
