At $1,662 in the stated June 2026 period, the Zillow Observed Rent Index is a typical observed asking-rent index, blended across rental types rather than a record of executed leases. It increased 10.9% from the same month a year earlier. Translating that monthly asking-rent index into a 30% income screen produces $66,480 of annual income; the matched area’s median household income is $54,644. This is arithmetic only—not affordability advice, a tenant-screening standard, or an applicant qualification rule—but it frames the central tension: annual income under the screen exceeds the reported median-income benchmark.
The prior rent path supports that tension, but it does not make a projection. Direct Zillow ZIP history recorded exact same-month annualized changes of 10.9% over one year, 9.9% over three years, and 9.1% over five years. The latest direction therefore confirms the longer upward path and is modestly faster rather than reversing it. Classified as high variability, annualized monthly-return variability of 3.7% means a single current index reading deserves bounded confidence even with 98.3% historical coverage. Its maximum drawdown was 2.3%, demonstrating a past decline within the rise. The transparent national discovery ranks among history-eligible ZIPs were 28 for momentum, 2,431 for stability, and 629 for the balanced score, with lower rank higher; these are backward-looking measurements, not forecasts or investment recommendations.
The 60628 label serves as both a Zillow ZIP market identifier and a matched Census ZCTA. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. The ACS 2024 five-year median gross rent is $1,193, and the current asking-rent index is 39.3% above that figure. ACS is a five-year survey of occupied renter homes, and its gross-rent measure includes selected utilities, so it should not be read as an older version of Zillow’s advertised-rent signal. The survey reports 5,435 renter households paying 30% or more of income toward rent, a 59.1% burden share. That burden statistic describes surveyed households, not any specific unit or future tenant, and it does not determine whether a listed rent will be paid.
Bedroom detail is modelled rather than observed. HUD’s FY2026 FMR/SAFMR ladder is an administrative, bedroom-specific standard—not asking rent—and the provided two-bedroom benchmark is $1,490. Scaling the ZIP ZORI by that local HUD ladder produces monthly modelled estimates of $1,383 for a studio, $1,472 for one bedroom, $1,662 for two bedrooms, $2,142 for three bedrooms, and $2,476 for four bedrooms. These are not measured bedroom rents, lease comparables, or promises of availability. The modelled two-bedroom estimate is 11.5% above the HUD standard. The ladder provides a standardized bedroom lens on the ZIP index, but it cannot resolve a particular building’s layout, utilities, condition, lease terms, or concessions.
Survey housing-stock evidence points to a sizeable stock but not to unit-level supply. The ZCTA has 28,615 housing units and a 19.5% vacancy rate. ACS categories include vacant units classified as for rent, but they are not a current availability feed and do not establish vacancy for a particular address. They also cannot identify the condition, asking rent, bedroom count, lease status, or timing of a given listing. The stock and vacancy measures nevertheless add context to the asking-rent and household-burden tension: area-level housing counts can coexist with a current rent-income screen that is more demanding than the reported median-income benchmark.
Broader benchmarks underline that the ZIP’s lower index does not automatically make its income screen easy. For wider context only, Chicago city’s rent context is $2,409, Cook County’s county-level rent context is $2,336, and the Chicago-Naperville-Elgin, IL-IN-WI metro rent context is $2,275; each lies above the ZIP index. These city, county, and metro figures have their stated wider scope and are context rather than ZIP rental comparables, property economics, or substitutes for the ACS survey and HUD administrative measures.
Resale data pull in another direction. Redfin’s direct rolling-three-month ZIP for-sale observation—not rental transactions—puts median sold price at $164,963, down 8.4% year over year. It recorded 179 homes sold and 69 median days on market, with inventory of 289 homes and 4.9 months of supply. Sales averaged 97.4% of list price, and 29.3% sold above list. Annualized ZIP ZORI divided by that median price equals a 12.1% cross-source screening ratio only; it is not a cap rate, net return, expected return, or property yield. The price decline and below-list average challenge a simple reading that rent-history momentum and the income screen alone describe current conditions, while the sales, marketing-time, inventory, and supply figures document resale liquidity rather than tenant demand.
Several limits matter before applying these area measures to a property. Zillow is an asking-rent index across rental types; ACS is a surveyed occupied-household measure with margins of error; HUD is an administrative standard; and Redfin is an observed resale series. None verifies effective rent, tenant turnover, sale proceeds, operating costs, or the outcome for an individual address. Concrete checks should match the unit’s bedroom count and condition to current advertised rents, document utilities, concessions, and lease length, distinguish asking rents from signed rents, and review nearby closed sales alongside active listings and list-price changes. The useful question is whether property-specific evidence matches these distinct ZIP, ZCTA, HUD, and resale measures rather than whether any one benchmark can answer it alone.
