Lyon County’s underwriting tension is a positive current rent-to-price indication against costs and flood exposure that are not resolved by county averages. The supplied county median home value is $420,180 and median asking rent is $1,920 per month, yielding 5.48% gross before financing, vacancy, insurance, repairs or tax. This is a diligence case for buyers who can underwrite a specific property’s expenses; it warrants caution for those relying on headline yield or countywide hazard data. The asking-rent metric, not HUD FMR, supports that calculation.
Price evidence is directionally positive but not interchangeable. FHFA’s annual 2025 repeat-transaction HPI increased 2.36%; it is an appreciation index, not a dollar value, and it must not be averaged with the separately dated June 2026 Zillow home-value observation. HUD’s two-bedroom FMR is a payment standard, not an asking-rent estimate. The effective property-tax rate is 0.46%, a carrying-cost input that should be checked against the parcel assessment and available exemptions.
Realtor.com’s MLS evidence shows active listings down 34.95%, median marketing time of 42 days, and 11.24% of listings reduced. These are visible-supply, marketing-time and seller-concession measures—not closed sales or standalone proof of buyer demand. Net migration was 554 tax-return households, while moving-in households had average AGI $11,119 above moving-out households. Investors made 50 of 1,162 purchases, or 4.3%; participation exists but is not the dominant purchase channel.
Climate modeling assigns a 0.24% annual building-value loss ratio and identifies inland flood as the dominant hazard; this is modeled loss, not a property condition. Flood-zone review, elevation, prior-loss history and an insurance quote remain decisive. The county QCEW series measures annual covered employment at workplaces, not resident employment or unemployment; its wage is a covered-worker average, and Trade, transportation, and utilities is only the largest disclosed private supersector, not the whole economy. Missing parcel insurance, operating expenses, financing terms, transaction-sale evidence, vacancy and lease quality prevent a net-cash-flow, acquisition-price and property-specific risk conclusion.
