Delaware County presents a valuation-versus-underwriting tension: its measured home-value direction is positive, but income underwriting is incomplete and listing concessions deserve review. Buyers relying on documented operating yield should be cautious; buyers able to validate leases, assessments and flood costs should investigate. Zillow's county median home value was $247,520 in its 2026-06 observation. FHFA's separate 2025 repeat-transaction HPI rose 2.10% annually and 48.12% over five years; it corroborates appreciation direction, not a dollar value or a rate to combine with Zillow.
Market rent is not published, so gross yield cannot be computed. HUD's two-bedroom FMR of $919 monthly is a payment standard, not evidence of market asking rent. The 1.34% effective property-tax rate is a carrying-cost input alongside the home's value, but assessed value, insurance, utilities, repairs, financing and lease terms are not published. That prevents a net-cash-flow or tax-and-rent coverage conclusion.
Realtor.com's 2026-06 MLS snapshot shows visible supply increased year over year, while median asking price fell and marketing time shortened. A 20.46% price-reduced share and 25% pending-to-active ratio indicate seller concessions; neither is a closed-sale measure or proof of buyer demand. QCEW annual covered jobs at county workplaces grew 3.39%; Manufacturing, the largest disclosed private supersector, represented 32.18% of total private covered jobs, a concentration to diligence rather than the whole economy. Tax-return migration was a net loss of 31 households: inbound movers' average AGI was $54,969 versus $56,505 for outbound movers. Investors accounted for 17 of 228 purchases, or 7.46%, so non-owner competition appears present but not dominant in this mortgage-purchase measure.
Flood is the dominant hazard, and modeled annual climate loss equals 0.23% of building value; this is modeled exposure rather than a property-specific loss estimate. It changes the underwriting focus to location-level flood history, elevation, coverage availability and deductible terms before treating tax or rent assumptions as durable. County evidence cannot establish neighborhood liquidity, achieved rents, property condition, assessment appeals or insurance premiums. Next checks are address-level flood and insurance quotes, current rent rolls and lease comps, closed-sale comparables, and tax bills.
