Dubuque County presents an underwriting tension: two price measures point upward, while workplace employment, migration and flood exposure call for property-level verification. Income-oriented buyers should test whether the published yield survives taxes, insurance and maintenance; buyers underwriting appreciation or an easy exit should be cautious because county evidence does not establish neighborhood liquidity or tenant depth.
The Zillow county observation labeled 2026-06 puts the median home value at $282,563, 5.53% above its prior-year reading. Separately, the FHFA repeat-transaction HPI annual observation for 2025 increased 5.24%, with a 44.28% cumulative five-year index change; this supports direction, but it is not a home value and cannot be blended with Zillow’s differently dated, differently constructed measure. Published median asking rent is $1,132 monthly and the supplied pre-cost gross yield is 4.81%. HUD’s two-bedroom FMR is $1,077, a payment standard rather than asking rent. The effective property-tax rate is 1.23%; expenses beyond that are not published, so net yield is unresolved.
Demand evidence is mixed rather than a verdict on absorption. Annual QCEW records covered jobs at county workplaces, not resident employment, and shows employment falling while covered-worker wages rise; trade, transportation, and utilities is the largest disclosed private supersector, not the entire economy. Tax-return migration netted -21 households, and incoming movers’ average AGI was $2,995 below outgoing movers’, a combination that does not demonstrate renter demand. Investors made 147 of 1,214 purchase mortgages, or 12.11%; that records participation, not bidding pressure by submarket or property type. Realtor.com MLS listing price, active inventory, days on market and reduction data are not published, preventing an assessment of visible supply, marketing time and seller concessions.
Inland flood is the dominant hazard, while modeled expected annual climate loss equals 0.13% of building value; it is a modeled county-level loss ratio, not a property flood determination. Missing insurance quotes, flood-zone status, elevation, replacement cost, operating expenses, lease terms and vacancy prevent a defensible net-cash-flow conclusion. Next checks are parcel-specific flood and insurance review, actual comparable rents and leases, and MLS-level sale and listing histories; these would test whether the county yield and price signals apply to a target asset.
