Johnson County presents a split-price case: investors who can verify rent and flood exposure should investigate, while yield-led buyers should be cautious. Zillow’s supplied county median home value is $189,171, up 4.34% year over year, whereas FHFA’s supplied annual repeat-transaction HPI rose 0.30%. These are different vintages and measures—an index is not a home value—so they cannot be combined into a single appreciation reading. The tension is a higher Zillow value signal against nearly flat FHFA index movement.
Carrying-cost underwriting is constrained. No county market asking rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $884 per month is a payment standard, not market rent, and cannot substitute. The effective property-tax rate is 0.52%, with median annual tax of $709; without market rent, rent coverage cannot be tested, and neither figure establishes tax for a specific acquisition. Modeled climate loss equals 0.20% of building value annually, and inland flood is the dominant hazard. That combination requires parcel-level flood, insurance, and deductible review rather than a countywide loss estimate.
Realtor.com’s MLS listing-market evidence reads softer in visible supply, not necessarily closed-sale demand: 119 active listings, up 9.22%, alongside a median listing price down 1.17% year over year. Listings spent a median 74 days on market, and the reported price-reduced share indicates seller concessions; these are asking-market conditions and marketing time, not sale outcomes. Migration was net positive, while mover-in average AGI exceeded mover-out AGI by $6,297. Investor purchase mortgages were 23 of 242 purchases, or 9.50%, indicating participation but not control of all buyer behavior.
Employment adds a separate caution. QCEW’s 2025 annual record reports covered jobs at county workplaces—not resident employment or unemployment—with employment down 2.60% while average covered-worker weekly wage rose 5.09% to $846. Trade, transportation, and utilities was the largest disclosed private supersector by employment, not the whole economy. Before underwriting, obtain current market rent and lease terms, operating and insurance quotes, parcel flood data, tax assessment details, and closed-sale comparables. Without rent and expenses, cash flow and yield remain untested; without property-level hazard and sale evidence, loss exposure and exit pricing remain untested.
