Johnson County presents a diligence case rather than a clean rental thesis: Zillow’s 2026-06 county reading puts the median home value at $218,201, up 1.74%, while the record shows outmigration and inland-flood exposure. Buyers who can verify rent, flood history, insurance, and taxes should investigate; buyers relying on county appreciation or a payment standard should be cautious. This is a Zillow home-value measure, not a closed-sale price, and no FHFA annual HPI observation is supplied to test its direction.
Market asking rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $982 per month, but it is a payment standard rather than evidence of county asking rent and cannot fill that gap. The property-tax rate is 1.32%, with median property tax of $2,052; these provide a carrying-cost check but not a specific property bill. Modeled climate loss is 0.21% of building value per year, aligned with inland flood as the dominant hazard; it is modeled loss, not an insurance quote.
Labor evidence is constructive but concentrated: 2025 QCEW shows 1,461 annual average covered jobs, up 4.81%, and a $1,099 average weekly covered-worker wage. Trade, transportation, and utilities accounts for 259 covered jobs and 37.43% of private covered employment; it is the largest disclosed private supersector, not the whole economy. Tax-return migration is negative by 24 households, although arriving movers’ average AGI exceeds departing movers’ by $19,649. Three investor purchase mortgages, or 9.68% of 31 purchase mortgages, are a limited county-level measure of buyer competition rather than total transaction activity.
Listing-market evidence is missing: the Realtor.com inventory observation does not publish median MLS listing price, active listings, days on market, price-reduced share, or pending ratio. That prevents a read on asking-price discipline, supply, marketing time, and concessions; even if present, these would be listing rather than closed-sale evidence. Before underwriting, obtain market asking rents and lease terms, property-level tax and insurance quotes, flood-zone and claims history, and sale comparables. County aggregation and absent FHFA data limit conclusions about submarket liquidity or appreciation.
