Johnson County’s decision tension is a rising value base against a pre-cost income measure that leaves limited room for unmeasured expenses. Zillow puts the county median home value at $287,697, up 5.39% year over year, while measured median asking market rent is $1,027 per month and gross yield is 4.28%. Buyers seeking durable net income should investigate property-level expenses and rent comparables; buyers relying on appreciation or thin cash-flow margins should be cautious.
That gross yield is based on annual market rent before costs, not a net return. HUD’s $965 FMR is a payment standard, not an asking-rent estimate, and must not substitute for the measured market rent. The effective property-tax rate is 0.66%, an identified carrying-cost input but not a parcel-specific tax bill. Financing, insurance, maintenance, vacancy, utilities, turnover and management costs are not published, preventing net operating income, debt-service coverage and property-specific cash-flow conclusions.
At the listing-market level, Realtor.com shows median marketing time up 51.63%, with 17.43% of listings price-reduced. These are MLS evidence on marketing time and seller concessions, not closed-sale prices or proof of buyer demand. QCEW measures annual covered employment at county workplaces rather than resident employment; Trade, transportation, and utilities is the largest disclosed private supersector. Net tax-return migration was 42, but arriving movers’ average AGI was $1,031 below departing movers’. The record reports 130 investor purchases among 856 total purchases, or 15.19%; this identifies non-occupant mortgage participation, not all buyer competition.
FHFA’s 2025 repeat-transaction HPI rose 4.74% annually, confirming Zillow’s positive direction but not supplying a dollar home value. Its method and vintage differ from Zillow’s, so the measures cannot be averaged into one appreciation rate. Inland flood is the dominant hazard, while modeled annual building-value loss is 0.11%; neither identifies parcel exposure, insurance pricing or mitigation needs. Obtain address-level flood maps, insurance quotes, condition reports, lease/rent comps and closed-sale comparables. Without them, an underwriter cannot establish parcel net cash flow, valuation or resale liquidity.
