Brookings County presents a valuation-versus-income tension: Zillow’s county median home value is $329,196, while median asking rent is $1,084 per month and the reported gross yield is 3.95% before costs. Investors needing robust initial cash flow should be cautious; investors investigating price resilience need property-level expense tests. Zillow shows 5.67% year-over-year value growth, while the FHFA annual repeat-transaction HPI changed 1.06% in its 2025 period. These are different methods and vintages, not growth rates to average.
Rent is measured market asking rent; HUD’s two-bedroom FMR of $953 is a payment standard, not an asking-rent estimate or a substitute for yield. The reported yield therefore properly rests on market rent, but remains gross and before taxes, insurance, maintenance, vacancy or financing. The effective property-tax rate is 1.13%; that carrying cost makes the low gross yield more sensitive to the unreported expense stack.
Realtor.com’s MLS listing-market evidence shows 64 active listings, down 36.50% year over year, with shorter marketing time. That signals constrained visible supply, but listing prices are asking prices and neither supply nor marketing time proves closed-sale demand. Tax-return migration was negative by 53 households, and incoming movers’ average AGI trailed outgoing movers’ by $1,403, a demand-depth caution. QCEW reports annual covered jobs at county workplaces, with job and wage growth and Manufacturing as the largest disclosed private supersector; it is not resident employment, unemployment or a forecast. Investor mortgages were 10.39% of 308 purchases, indicating some buyer competition but not the owners’ hold periods or rent strategy.
Inland flood is the named dominant hazard; modeled annual climate loss is 0.13% of building value, not a property-specific loss estimate. Verify flood zone, prior claims, insurance availability and deductibles before relying on county averages. Missing operating expenses, financing terms, vacancy, lease renewals, submarket closed sales and property condition prevent an NOI, debt-coverage, resale-price or property-level hazard conclusion. Next checks should pair actual leases and taxes with insurance quotes, inspection findings and recent comparable sales.
