Union County presents a valuation-confirmation problem, so buyers relying on near-term appreciation and lenders using automated value assumptions should investigate rather than treat it as a clean momentum case. Zillow’s June 2026 county median home value was $136,006, up 3.78% year over year; FHFA’s 2025 annual repeat-transaction HPI declined 1.75%. The measures differ in vintage and method: Zillow tracks a home-value estimate, while FHFA is an index rather than a dollar value. They cannot be averaged into a single growth rate.
Housing economics remain unproven for rental underwriting. Market asking rent is not published, so gross yield cannot be computed against the Zillow value or any acquisition basis. HUD’s $1,038 two-bedroom FMR is a payment standard, not evidence of asking rent, and cannot substitute for it. The effective property-tax rate is 0.56%; without market rent, its burden cannot be tested against income. Unit-level taxes, insurance, repairs, vacancy and utilities are also not published.
MLS listing-market evidence shows a visible but not self-explanatory seller environment. In Realtor.com’s June 2026 observation, active inventory was 17% above a year earlier and 18.04% of listings had price reductions; these are supply and concession signals, not closed-sale prices or proof of demand. Tax-return migration was positive by 53 households, and movers in reported average AGI $6,284 above movers out, but county aggregates do not identify renter demand or neighborhood destination. The 1.77% investor share across 226 purchases limits evidence of broad investor buyer competition.
Risk controls should center on inland-flood exposure and data gaps. The modeled annual climate-loss ratio is 0.10% of building value, but it is not a site-specific insurance quote or a dollar loss; flood-zone, elevation, prior-loss, deductible, replacement-cost and coverage-availability checks remain necessary. The 2025 QCEW workplace series shows covered employment declined while average weekly wage rose; Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Missing lease comps, market rent, operating expenses, insurance and closed-sales data prevent a stabilized cash-flow, yield, resale-price or tenant-demand conclusion.
