DuPage’s tension is measured gross income against carrying costs and inland-flood screening, while listings show marketing time alongside concessions. Investors who can validate taxes, insurance, leases and parcel flood exposure should investigate; buyers relying on appreciation, county averages, or HUD standards should be cautious. Zillow’s 2026-06 county series reports a $449,185 median home value and $2,140 monthly median asking rent. That is market rent, not a guaranteed lease rate; the supplied 5.72% gross yield is before taxes, insurance, vacancy, maintenance, financing, or management.
At a 2.05% effective property-tax rate, the $8,007 median annual tax can materially reduce the gross yield, so acquisition review needs actual assessments and appeals history. HUD’s $1,781 Fair Market Rent is a payment standard, not an estimate of asking rent; reported market asking rent is 20.20% higher by calculation. FHFA’s separate 2025 annual repeat-transaction HPI increased 6.24%. That corroborates an upward index direction, but it is not a dollar home value and does not share Zillow’s method or observation window; the two changes cannot be averaged.
Realtor.com’s MLS listing-market evidence shows visible active supply, 26 median days on market, and 11.53% of listings with price reductions. These figures describe asking supply, marketing time, and seller concessions—not sale prices or buyer demand alone. Tax-return migration was a net outflow of 3,567 households, while incoming and outgoing mover average incomes were nearly identical. Non-occupant purchase mortgages were 768 of 8,950 purchases, or 8.58%; this identifies some buyer competition but does not reveal the target property’s segment, cash buyers, or hold strategy.
QCEW annual covered employment at county workplaces rose 1.17%; it is not resident employment, unemployment, or a forecast. Trade, transportation, and utilities is the largest disclosed private supersector, not the whole county economy. Modeled climate loss is 0.10% of building value annually and inland flood is the dominant hazard, requiring parcel-specific flood, insurance, drainage, and deductible review. Missing sale comps, vacancy, operating expenses, insurance quotes, property condition, and flood-zone data prevent a net-yield, resale, or site-risk conclusion.
