Johnson County’s tension is a still-rising valuation and constrained visible listing supply alongside slower MLS marketing signals; it merits investigation for buyers who can validate property-level rent and flood exposure, while those relying on rapid resale should be cautious. Zillow’s June 2026 county median home value was $313,517, up 3.71% year over year. FHFA’s 2025 repeat-transaction HPI increased 4.55%; it corroborates positive direction but is not a home value and comes from a different observation period and method. Realtor.com’s June 2026 MLS median listing price rose 9.37%; it is an asking-price signal, not a closed sale. Longer marketing time, price reductions, and fewer active listings complicate any simple demand reading.
The supplied median asking rent is $1,383 per month, and the supplied gross yield is 5.29% before operating costs. That yield relates to measured market rent and price, not HUD’s $1,141 two-bedroom FMR; FMR is a payment standard, not an asking-rent estimate. Carrying-cost scrutiny is material: the effective property-tax rate is 1.52% and median annual tax is $4,681. The county medians do not provide insurance, maintenance, financing, vacancy, or neighborhood-level taxes, so net yield and property-specific debt coverage cannot be underwritten from this record.
Demand evidence is mixed rather than self-confirming. The county recorded net outmigration of 466 tax-return households, and households moving in had average income $7,500 below those moving out. Annual QCEW data nevertheless show covered workplace employment and covered-worker wages increased; these are job locations, not resident employment or a demand forecast. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. The 11.06% investor share is measured against purchase mortgages, signaling meaningful competition but not proving that investor buying drives pricing or rents.
Inland flood is the dominant hazard, and modeled annual building-value loss is 0.19%; this is modeled county-level exposure rather than a parcel flood determination. The record does not publish closed-sale prices, rent by unit type, vacancy, insurance, flood-zone status, financing terms, or operating expenses. Next checks are parcel flood and insurance quotes, lease and concession history, tax bills, and closed comparable sales; without them, resale liquidity, net cash flow, and hazard-adjusted value remain unresolved.
