Martin County presents a valuation-timing tension for investors who need corroborated appreciation rather than a single headline. Zillow’s county median home value was $224,849 in 2026-06, up 5.99% year over year, while FHFA’s repeat-transaction HPI rose 0.60% in 2025 and 39.61% cumulatively over five years. These are different methods and observation periods: FHFA is an index, not a home value, and neither series should be averaged into one growth rate. Buyers relying on near-term value support should investigate the divergence with local closed-sale evidence.
No median asking market rent is published, so gross yield cannot be computed. The $973 two-bedroom HUD Fair Market Rent is a payment standard, not an estimate of local asking rent, and cannot substitute for it. The reported effective property-tax rate is 1.02%, with median annual property tax of $1,671. Those figures provide a carrying-cost screen, but they do not establish taxes for a particular home or compensate for the missing rent evidence needed to test income coverage.
County workplace conditions are mixed rather than a direct tenant-demand measure. In 2025, QCEW annual average covered employment grew 1.65%; Trade, transportation, and utilities was the largest disclosed private supersector, representing 30.17% of private covered jobs. Tax-return migration showed a net outflow of 84 households, while incoming movers’ average income was $16,184 below that of outgoing movers. Non-occupants accounted for 11 of 198 purchase mortgages, or 5.56%, indicating limited recorded investor participation rather than a definitive measure of all-cash competition.
Inland flood is the dominant hazard, and modeled expected annual building-value loss is 0.11%. That county-level ratio does not identify parcel exposure, flood-zone status, insurance availability, prior losses, or mitigation needs. The supplied 2026-06 Realtor.com record has no MLS listing figures, preventing a screen of visible supply, asking-price concessions, and marketing time. Before underwriting, obtain property-level flood and insurance records, current market rents, lease and vacancy data, and local closed-sale comparables; without them, neither cash flow nor resale liquidity can be tested.
