Kankakee County offers a respectable gross-rent screen but a mixed underwriting case: the $225,852 median price and 7.19% gross yield meet soft employment and migration evidence. Investigate tenant durability, taxes, and flood exposure before treating that yield as stabilized. Zillow reports 6.61% price growth for 2026-06; FHFA’s repeat-transaction HPI reports 2.97% for 2025. They are different methods and periods, and FHFA is an index, not a home value; reconcile closed sales rather than average growth.
Measured asking rent is $1,353 monthly, up 4.05%; it is not a HUD estimate. It is 2% above HUD’s two-bedroom FMR, which is a payment standard, not market rent. The 7.19% gross yield is before costs, and the 2.22% effective property-tax rate narrows it. Insurance, flood deductibles, vacancy, repairs, utilities, management, and financing remain separate. Missing operating expenses, unit mix, lease data, and parcel assessment detail prevent net-yield and cash-flow underwriting.
Realtor.com MLS evidence shows fewer active listings, longer marketing times, and price reductions: visible supply and seller concessions, not closed-sale prices or proof of demand. The 2025 QCEW record shows covered employment down 0.68% while covered wages rose 4.47%; it measures workplace jobs, not resident employment or unemployment. Education and health services is the largest disclosed private supersector, not the whole economy. Net tax-return migration was -26, with inbound average AGI $4,440 below outbound. Investors made 120 of 1,184 purchase mortgages, or 10.14%: competition exists, but dominance is unproven.
Risk limits are material. Inland flood is the dominant hazard, and modeled annual building loss is 0.20%; that is not an insurance quote or property-level flood determination. Obtain flood-zone, elevation, insurance, claims, and condition evidence, plus closed-sale comparables and lease concessions. The record lacks these items, so insurance-adjusted NOI, cap rate, and cash flow cannot be determined. The next check is whether verified rent survives local competition after tax and flood costs.
