Sullivan County presents a yield-versus-carrying-cost tension: the published median asking rent of $1,703 against a $328,990 median home value produces a supplied 6.21% gross yield before expenses, while the effective property-tax rate is 2.0%. Investigate properties with verified operating costs and flood protection; be cautious where tax, insurance and repairs consume the gross spread. This is a county-level screen, not a property cash-flow result.
The Zillow county observation is labeled 2026-06, and its median home value rose 3.98%. FHFA’s annual 2025 repeat-transaction HPI rose 2.32%. Both point upward, but the vintages and methods differ: FHFA is an index, not a dollar home value, and the rates must not be averaged. The published asking rent, rather than HUD’s two-bedroom FMR, supports the gross-yield screen; FMR is a payment standard, not an asking-rent estimate.
Realtor.com’s separately labeled 2026-06 MLS listing-market record shows active inventory up 13.04%, median marketing time of 54 days, and price reductions on 16.46% of listings. These are visible supply, marketing time and seller concessions, not closed-sale prices or proof of buyer demand. Tax-return migration was -69 households, although incoming movers had higher average AGI than outgoing movers. QCEW reports annual covered employment at county workplaces and wage growth, not resident employment or unemployment; Education and health services is the largest disclosed private supersector, not the whole economy. Investor-financed mortgages accounted for 24.21% of purchases (208 of 859), indicating participation in the purchase-mortgage channel without identifying properties or bidders.
Inland flood is the dominant hazard, and the published modeled annual building-value loss ratio requires parcel-specific review; it is not a measured loss for any one home. No property-level flood zone, elevation, insurance quote, condition, utilities, vacancy, operating-expense, financing-term or closed-sale price evidence is published. Those omissions prevent net-yield, debt-coverage, replacement-cost-exposure and exit-price underwriting.
