Sussex County presents a valuation-versus-cash-flow tension: reported county home-value growth and a stronger transaction index point upward, but income return is unmeasured. Investors able to collect property-level rents and flood terms should investigate; buyers relying on appreciation headlines or a quick yield screen should be cautious. Zillow’s June 2026 county median home value is $188,187, up 4.98%, while the FHFA 2025 annual repeat-transaction HPI increased 11.82%. They use different methods and source periods, so neither is a sale price for a specific asset and they should not be combined into one growth rate.
No county market rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $1,655 per month is a payment standard, not observed asking rent, and cannot substitute for it. The effective property-tax rate is 0.59%; it is a carrying-cost input to test against actual rent and assessed value, rather than evidence that the median value produces a given return.
County demand and buyer competition offer little confirmation. QCEW records annual average covered jobs at county workplaces, down 1.77%; it is not resident employment or an unemployment measure. Tax-return migration shows 308 households moved in and 288 moved out, a net gain, but incoming movers’ average income was $7,386 lower, a calculation from the supplied averages. Investor purchase mortgages numbered 4 of 81 purchases, or 4.94%, indicating a small observed non-owner mortgage share rather than all-cash investor activity. No Realtor.com MLS listing, inventory, marketing-time, or price-reduction figures are published, so visible supply and seller concessions cannot be assessed.
Inland flood is the dominant hazard. The modeled climate loss ratio is 0.09% of building value per year; it frames a hazard-screening input, not a parcel-specific insurance premium or damage forecast. Underwriting needs flood-zone status, elevation, prior losses, coverage availability, deductibles, and renewal terms before carrying costs can be bounded. The missing market-rent series prevents any gross-yield conclusion, while absent closed-sale, assessment, and property-condition evidence prevents a price-to-basis or tax reassessment conclusion. County-level evidence also cannot establish performance for a neighborhood or individual house.
