In 60641, the strongest tension is between a firmer direct ZIP resale picture and a still-growing but less forceful asking-rent path. Redfin’s rolling-three-month ZIP for-sale observation reports a $543,877 median sold price, up 10.32% year over year, with 151 homes sold and a 41-day median marketing time. Inventory stood at 98 homes and 2.0 months of supply. Average sale-to-list was 103.55%, while 56.52% of sales closed above list. Annualized ZIP ZORI divided by median sold price produces a 3.82% cross-source screening ratio only; it is not a cap rate, net return, expected return, or property yield. These are resale signals, not rental transactions or property-specific economics.
The June 2026 Zillow ZORI reading is $1,731, a typical observed asking-rent index blended across rental types, and it increased 5.04% from the same month a year earlier. That differs from the matched ACS 2024 five-year median gross rent of $1,300, making the asking index 33.15% higher. ACS reflects occupied renter homes and includes selected utilities, whereas Zillow is an asking-rent index rather than a survey of existing tenants. A ZCTA is a Census statistical area and is not identical to a USPS delivery ZIP, even though this five-digit Zillow market identifier is matched to the Census ZCTA for this report. HUD’s $1,720 two-bedroom standard is also a separate administrative benchmark, not asking rent.
The bedroom view is a modelled ladder, not a set of measured bedroom rents. Scaling ZIP ZORI by the local HUD bedroom ladder produces modelled monthly estimates of $1,439 for a studio, $1,540 for one bedroom, $1,731 for two bedrooms, $2,224 for three bedrooms, and $2,576 for four bedrooms. The resulting shape follows HUD’s local bedroom-specific FMR/SAFMR proportions; HUD FMR/SAFMR is an administrative standard and should not be read as a listing comp or a prediction of a lease quote. The two-bedroom model point aligns with the ZIP-wide index because the ladder scaling anchors there, not because observed two-bedroom asking rents were directly measured.
Arithmetic screens are less strained than the ACS burden record might initially suggest, but they answer different questions. The matched ZCTA median household income is $83,758. At a 30% income share, annualizing the current Zillow index implies $69,240 of required income, and the index equals 24.8% of that area median household income. This 30% screen is arithmetic only, not advice and not an applicant qualification rule. Separately, ACS reports 5,700 of 12,332 renter households as spending at least 30% of income on rent, a 46.22% burden share. That occupied-home survey measure cannot prove affordability, rent burden, or payment capacity for any particular available unit.
The matched ZCTA’s housing base provides useful scale but not live unit availability. It contains 27,500 housing units, and the reported overall vacancy rate is 5.68%; 416 vacant homes were classified as for rent. Renter occupancy represents 47.54% of occupied homes, while the housing stock includes both single-family and larger multifamily structures. Overall vacancy includes categories beyond units offered for rent, and even the for-rent vacancy count is a survey-based area measure rather than proof that a selected building has an opening. The stock and vacancy figures therefore frame the local housing mix and broad availability conditions without substituting for a current property search.
Broader rents place the ZIP index below every supplied comparison geography, but those values remain context rather than substitutes for ZIP evidence: the City of Chicago context asking-rent figure is $2,408.80, the Cook County context asking-rent figure is $2,336, and the Chicago-Naperville-Elgin, IL-IN-WI metro context asking-rent figure is $2,275. The City of Chicago, Cook County, and metro each cover substantially wider areas than this ZIP. Their renter shares, gross-rent surveys, and vacancy measures likewise describe their own scopes. The metro apartment vacancy measure is an apartment-market context statistic, while Zillow ZORI, ACS gross rent, HUD standards, and Redfin sales each retain separate measurement universes.
Backward-looking Zillow history supports a stable-growth label, while also showing some cooling in the growth rate. Exact same-month annualized changes were 5.04% over one year, 5.51% over three years, and 6.36% over five years. The recent direction therefore confirms the longer upward path but does so at a slower annualized pace than the longer windows. Monthly rent-return variability annualizes to 2.04%, indicating a relatively contained historical range rather than a guarantee about the next reading. Its maximum drawdown was 1.97%, a shallow historical pullback that supports more confidence in continuity than a highly erratic series would. Coverage is 100%, and the transparent national discovery ranks are 281 for momentum, 159 for stability, and 28 for the balanced measure, with lower ranks stronger. These are historical measurements, not forecasts or investment recommendations.
Current evidence is best used as a bounded screening package. Zillow gives a ZIP-level asking-rent index rather than a unit quote; ACS adds survey-based occupied-home conditions; HUD supplies bedroom-specific administrative standards; and Redfin describes direct ZIP resale activity only. Before relying on the modelled ladder or cross-source screen, verify the actual advertised rent, bedroom count, lease term, included utilities, concessions, availability, building condition, and comparable active listings for the property under review. Also distinguish a sale observation from a rental comp and a survey vacancy estimate from a confirmed opening. Do the actual lease terms and unit-level evidence support the index-based screen?
