Codington County presents a valuation-versus-income tension: the 2026-06 Zillow county median home value of $350,332 is paired with measured median asking rent of $1,212 per month and a supplied 4.15% gross yield before costs. This warrants investigation by buyers who can verify operating expenses and caution for those relying on price appreciation. The effective property-tax rate is 0.97%, a material carrying-cost input. HUD’s two-bedroom FMR is a payment standard, not market asking rent, and cannot substitute for the measured rent or yield.
Price evidence points upward at different speeds, not one comparable rate. Zillow’s 2026-06 median value rose 1.93% year over year; FHFA’s 2025 repeat-transaction HPI rose 3.47% annually and 46.64% cumulatively over five years. FHFA is an index rather than a dollar home value. Its direction supports, but does not quantify beyond, Zillow’s direction because their vintages and methods differ. Neither measure establishes a closing price.
MLS listing-market evidence provides a more conditional demand signal. Realtor.com shows a 58-day median marketing time and 19.53% of listings price-reduced; these are seller-concession and exposure measures, not closed-sales evidence or standalone proof of buyer demand. Net tax-return migration was 75 households, while incoming movers’ average AGI exceeded outgoing movers’ by $9,315, a potentially supportive composition signal with limited household-level relevance. Investors accounted for 5.5% of 309 purchase mortgages, indicating limited observed non-owner competition rather than all-cash or total buyer participation.
The principal risk overlay is inland flood: modeled expected annual building-value loss is 0.16%, which must be tested against parcel flood exposure, insurance availability and deductibles rather than converted into a dollar estimate. QCEW covers jobs at county workplaces, not resident employment; its largest disclosed private supersector, Trade, transportation, and utilities, is not the whole economy. Missing operating expenses, insurance quotes, vacancy, lease terms, property condition, parcel hazard maps, sale comparables and financing terms prevent a net-yield, cash-flow, resale-liquidity or asset-level flood conclusion.
