Jo Daviess County’s decision tension is price momentum against untested cash flow and flood-sensitive collateral. Investors requiring verified yield, and lenders assessing flood exposure, should investigate rather than treat appreciation as sufficient support. Zillow’s 2026-06 county median home value was $254,886. FHFA’s separate annual repeat-transaction HPI rose 7.86% and 46.11% over five years. These measures point in the same direction, but their methods and vintages differ: FHFA is an index, not a home value, and the growth rates cannot be combined.
Carrying costs are only partly observable. The effective property-tax rate is 1.72%, a recurring input relative to the value measure. HUD FMR is a payment standard, not observed asking rent. Since market rent is not published, gross yield cannot be computed; neither rent-to-price nor rent-to-tax coverage can be tested. The record also supplies no vacancy, leasing, insurance, maintenance or financing costs, preventing a net-income conclusion.
In Realtor.com’s matching MLS period, 151 active listings had a median marketing time of 57 days. Reduced listings indicate seller concessions within visible supply; asking prices, inventory and days on market are not closed-sale prices or proof of buyer demand. Net migration was negative by 63 tax-return households, although incoming movers’ average AGI exceeded outgoing movers’ by $6,619, a calculation from supplied averages. The supplied investor share was 13.85% of 195 purchases, indicating non-owner participation but not its effect on a target neighborhood.
At county workplaces, the QCEW annual record reports 7,552 covered jobs, and leisure and hospitality is the largest disclosed private supersector; this is neither resident employment nor a forecast. Inland flood is dominant, with modeled annual building-value loss of 0.12%. That model is county-level rather than parcel-specific. Missing parcel elevation, insurance quotes, claims history, rental comparables and closed-sale data prevent collateral-specific hazard pricing, income underwriting and a liquidity conclusion.
