Darlington County presents a cash-flow-versus-validation tension: Zillow’s 2026-06 median home value of $174,287 rose 10.78%, while FHFA’s 2025 annual repeat-transaction HPI rose 3.53%. These are different methods and vintages, so they cannot be averaged. Cash-flow underwriters should investigate the rent spread; appreciation-led buyers should be cautious until local transaction evidence validates the value signal.
Published median asking market rent is $1,182 per month, supporting the supplied 8.14% gross yield before expenses. HUD’s two-bedroom FMR of $1,098 is a payment standard, not an asking-rent estimate, and should not replace market rent in underwriting. The effective property-tax rate is 0.41%, a recurring carrying cost. Insurance, maintenance, vacancy, management, financing, and property-level assessments are not published, preventing a net-yield or cap-rate conclusion.
County workplace evidence is mixed. QCEW covered employment declined 1.08% while average weekly covered-worker wage increased 4.4%; Trade, transportation, and utilities accounts for 28.1% of disclosed private covered employment, indicating sector concentration rather than a description of the whole economy. Net tax-return migration was 28 households, but inbound movers’ average AGI was $882 below outbound movers’, tempering the headline gain. Investor purchases represented 5.67% of 617 purchases. Realtor.com’s MLS market shows fewer active listings alongside longer marketing time and price reductions; these are listing signals, not closed-sale demand.
Inland flood is the dominant stated hazard, and the modeled expected annual building-value loss ratio is 0.14%; this county-level measure is not a parcel loss estimate. A file should next obtain flood-zone and elevation data, insurance quotes, property condition, lease terms, actual sale comparables, and rent-by-unit evidence. Without them, the brief cannot establish insurability, site-specific hazard exposure, stabilized expenses, or whether MLS asking conditions translate into executable acquisition pricing.
