Cook County presents a decision tension: current income and price indices are firm, while household movement and flood exposure require caution. Zillow’s county median price is $343,350, up 4.97% in the 2026-06 observation. FHFA’s repeat-transaction HPI, not a home value, rose 5.52% in its annual 2025 observation. These are different vintages and methods, so they support the same direction without being averaged into one growth rate. The case suits an investor testing property-level cash flow; anyone relying on resident-demand growth or an index as a sale price should investigate more carefully.
Measured market rent is $2,336 per month, a median asking rent, and the published gross yield is 8.16% before costs. HUD’s two-bedroom FMR is $1,781, a payment standard rather than an asking-rent estimate; market rent is 31.20% above it by calculation. FMR therefore cannot substitute for market rent. The 1.91% effective property-tax rate adds a material carrying cost. The record does not publish vacancy, operating expenses, insurance, utilities, financing, or unit-level rent and tax detail, preventing a net-cash-flow or stressed-yield conclusion.
Demand evidence is mixed. Realtor.com MLS evidence shows active listings down 14.77% year over year; that is visible supply, not a closed-sale price or proof of buyer demand. Tax-return movers show net migration of -13,448, and the incoming-minus-outgoing average AGI gap is -$32,490, a weaker income profile for inflows. Investor mortgages represent 9.12% of 46,795 purchases, indicating participation but not control of the supplied purchase set. QCEW’s annual 2025 data show covered workplace employment up 1.10% and average weekly wage up 4.07%; these are workplace measures, not resident employment. Education and health services is the largest disclosed private supersector, not the whole economy.
Dominant inland flood is paired with a modeled annual building-value loss ratio of 0.14%, not a parcel flood determination or insurance quote. Obtain parcel flood-zone, elevation, drainage, claims, and insurance terms, then test deductibles, coverage, taxes, and repairs. Also verify lease-up, vacancy, utilities, assessment history, and financing. Those missing records prevent a hazard-adjusted return, liquidity, or final pricing conclusion; this county record supports screening, not final underwriting.
