McDuffie County presents a split underwriting frame: measured values are rising while its visible MLS market is loosening, so investors able to verify property-level rent and flood exposure should investigate; yield-dependent buyers should remain cautious. Zillow’s county median home value was $201,088 in 2026-06, up 4.79% year over year. Separately, FHFA’s repeat-transaction HPI rose 8.94% in annual 2025. These distinct measures and vintages show consistent direction, but the HPI is not a home value and cannot be blended with Zillow’s change.
Housing economics remain unproven because no county market asking rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $1,261 per month, but it is a payment standard, not measured asking rent, and cannot substitute in a yield calculation. The effective property-tax rate is 0.82%, a recurring carrying-cost input against the home-value reference. Insurance, maintenance, financing, vacancy, utilities, and property-level tax bills are not published; actual leased rent and operating statements are needed to test coverage.
Workplace evidence is context, not a demand forecast: QCEW reports 7,092 annual-average covered jobs, up 0.4%, and manufacturing—the largest disclosed private supersector—accounts for 29.74% of private covered employment. These are jobs at county workplaces, not resident employment or unemployment. The MLS listing market shows 96 active listings, up 55.28%, and an 82-day median marketing time, indicating more visible supply and slower marketing; it is not proof of buyer demand or a closed-sale price change. Tax-return migration was net positive, and average in-mover AGI exceeded out-mover AGI. Investor purchases were 6.25% of 208 total purchases, signaling limited but present competition.
Risk screening remains incomplete. Inland flood is the dominant hazard, and modeled expected annual climate loss equals 0.09% of building value; this is a modeled ratio, not a property loss estimate. County data cannot identify parcel flood history, insurance availability or premium, elevation, drainage, replacement cost, or lease resilience. The thesis could fail if market rent does not cover costs, listing conditions deteriorate before exit, or flood-related insurance and repairs exceed property underwriting. Next checks are parcel hazard records, insurance quotes, signed leases, operating statements, and recent closed comparable sales.
