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’s decision tension is an appreciation-positive but rent-softening setup: Zillow’s 2026-06 county median home value gained 1.38% while its median asking rent fell 0.07%, although the supplied gross yield is 4.93% before costs. It merits investigation by buyers who can verify property-level rents and expenses; underwriting that depends on rising rents or appreciation warrants caution. FHFA’s 2025 repeat-transaction HPI increased. That supports positive price direction, but it is an index—not a dollar value—and its method and vintage cannot be merged with Zillow’s.

02Housing economics

Market rent, rather than HUD FMR, underlies the stated yield. HUD FMR is $1,433 per month and the county’s measured asking rent sits 20.2% above it, but FMR is a payment standard, not an asking-rent estimate. The effective property-tax rate is 1.14%, with median annual tax of $3,947, a carrying-cost check against the gross yield. Insurance, repairs, vacancy, financing terms, and property-specific assessments are not published, preventing a net-yield or cash-flow conclusion.

03Demand & competition

Demand evidence is mixed. QCEW’s 2025 covered workplace employment grew; it is not resident employment or unemployment, and Professional and business services is the largest disclosed private supersector, not the whole economy. Tax-return migration recorded net inflow of 589 households, with average AGI of $102,901 for movers in and $87,310 for movers out—a reported $15,591 gap. Investor purchase mortgages were 33 of 1,148, or 2.87%, indicating limited observed non-owner participation. Realtor.com’s 2026-06 MLS evidence shows active listings rose 19.13%; listing prices, marketing time and reductions are asking-market signals, not sale prices or proof of buyer demand.

04Risk & next checks

Inland flood is the dominant hazard, and modeled annual building-value loss equals 0.12%, so flood exposure belongs in site-level insurance, elevation, drainage and loss-history diligence rather than a countywide discount. The record lacks property type, rent distribution, occupancy, closed-sale comps, insurance quotes, flood-zone status, and lease or expense details. Those omissions prevent testing whether gross yield survives operating costs or whether visible MLS supply translates into achievable acquisition pricing.

Bear case

What can break the county thesis

  1. Unpublished insurance, maintenance, vacancy, financing, and assessment costs could materially change net yield.
  2. County asking-rent movement may not represent achievable rents for a specific property type or submarket.
  3. Inland-flood exposure and insurance costs can vary materially by parcel despite the county-level modeled loss ratio.
