Macoupin County’s decision tension is differing price-momentum readings against missing rent evidence. Zillow’s county median home value was $139,618 in 2026-06, up 1.20% year over year. FHFA’s 2025 repeat-transaction HPI rose 5.20% annually; it tracks matched-sale price change rather than a home value. The readings point upward but belong to different vintages and methods, so they should not be blended. Buyers requiring a rent-supported return or stable tenant demand should investigate rather than treat appreciation as the thesis.
Housing economics are incomplete. No county market rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $916 per month, but it is a payment standard, not an asking-rent estimate and cannot fill that gap. The effective property-tax rate is 1.50%, with median annual tax of $2,073; these are carrying-cost inputs, not evidence of affordability or net cash flow. Insurance, utilities, maintenance, financing terms and property-specific assessments are not published, preventing a net-income conclusion.
Demand evidence warrants caution, not a population verdict. QCEW reports 9,915 annual average covered jobs at county workplaces, down 2.32% from its prior annual average; this is neither resident employment nor unemployment. Trade, transportation, and utilities is the largest disclosed private supersector, not the entire economy. Net migration was an outflow of 20 tax-return households, although incoming movers’ average AGI exceeded outgoing movers’ by $2,522; this does not establish tenant demand. Investors were 47 of 481 purchases, or 9.77%, showing non-owner-occupant participation but not cash buyers or all competition.
Inland flood is the dominant hazard, and the modeled climate-loss ratio is 0.13% of building value per year; it is a modeled loss measure, not a parcel insurance quote. Realtor.com figures are not published: median asking price, active listings, days on market, reductions and pending ratio cannot test visible supply, marketing time or seller concessions. Closed-sale prices, lease comps, flood-zone data and insurance quotes are also absent. The next diligence should test parcel-level flood exposure, insurability, leases and operating costs; without them, neither return resilience nor an exit-liquidity conclusion is supported.
