Yankton County presents an underwriting tension: modestly rising values and tighter visible listings sit beside shrinking covered employment and inland-flood exposure. Income-focused buyers should be cautious until property-specific rents and insurance are verified; operators with local leasing evidence should investigate. Zillow’s county median home value was $283,801 in 2026-06, up 1.48% year over year. FHFA’s annual 2025 repeat-transaction HPI rose 1.94%; it confirms direction, but is not a home value and cannot be combined with Zillow into one growth rate.
No median asking market rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $929 per month is a payment standard, not an asking-rent estimate, and cannot supply yield. The effective property-tax rate is 1.06%, but it does not establish a particular parcel’s tax bill. Verify achieved rent, vacancy, utilities, insurance, assessments and assessed value before judging carrying costs or cash flow.
Realtor.com’s MLS listing evidence reported 57 active listings, down 24.67% year over year, with shorter marketing time and some price reductions. These are visible supply, asking-market and seller-concession indicators—not closed sales or proof of buyer demand. Migration was slightly positive and movers-in reported higher average income than movers-out, a limited demand-quality positive. Investor purchase mortgages accounted for 13 of 216 total purchases; participation must be assessed against the full purchase base, not treated as the whole buyer pool.
QCEW’s 2025 annual workplace series showed covered employment down 1.75%, while Manufacturing, the largest disclosed private supersector, represented 28.39% of private covered jobs. This is workplace employment, not resident employment or an outlook; concentration warrants tenant and employer exposure checks. Modeled climate loss is 0.16% of building value annually and the named dominant hazard is inland flood, so obtain address-level flood, insurance and mitigation evidence. Rental vacancy, achieved rents, operating expenses, transaction prices and property-level hazard data are not published; their absence prevents cash-flow, yield, sale-price and insurability conclusions.
