At the stated Zillow endpoint, 60611’s typical observed asking-rent index was $2,790 per month. Zillow ZORI is a ZIP-level asking-rent index blended across rental types, so it is a market signal rather than a quote for a defined unit. For wider Zillow asking-rent context, the Chicago city figure was $2,408.80, the Cook County figure was $2,336, and the Chicago-Naperville-Elgin, IL-IN-WI metro figure was $2,275. The ZIP index therefore sits above each named broader-area context, but those city, county, and metro readings are comparison scopes rather than substitutes for ZIP evidence. That premium is the starting tension: it must be read alongside household affordability, available stock, and a resale market that supplies a separate, non-rental lens.
The five-digit label is 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. In the ACS 2024 five-year survey of occupied renter homes in that ZCTA, median gross rent was $2,479; gross rent includes selected utilities and is not an asking-rent measure. The Zillow asking index was 12.55% higher than that survey median, a difference consistent with the two series describing different populations and rent concepts rather than a direct conflict. HUD is another distinct universe: its bedroom-specific FMR or SAFMR is an administrative standard, not asking rent. The current index was 4.49% above the local two-bedroom HUD standard, which is useful for scaling but does not convert HUD into a lease-market observation.
Using the local HUD bedroom ladder to scale the ZIP ZORI produces modelled monthly estimates of $2,320 for a studio, $2,477 for a one-bedroom, $2,790 for a two-bedroom, $3,595 for a three-bedroom, and $4,159 for a four-bedroom. These are modelled estimates, never measured bedroom rents. Their purpose is to preserve the relative local HUD bedroom structure while anchoring the ladder to the blended ZIP asking-rent index. The matching two-bedroom model result should not be mistaken for evidence that an observed two-bedroom lease asks that amount. A particular property can differ because the index and ladder do not identify its exact unit mix, lease terms, included utilities, condition, or current availability.
The required-income screen puts the current asking index into arithmetic terms. Annualizing $2,790 produces a required household income of $111,600 at a 30% rent-to-income threshold. This is an arithmetic screen, not advice and not an applicant qualification rule. The ZCTA’s ACS median household income was $125,675, so the broad income benchmark is above that screen; it does not establish affordability for any individual household. Separately, 42.46% of the estimated renter households, or 6,294 of 14,823, reported paying at least 30% of income toward gross rent in the ACS burden measure. That burden result concerns surveyed occupied renter homes and cannot prove that a current listing, a given household, or a proposed lease carries the same burden.
Housing composition adds a counterweight to the premium asking-rent reading. The ZCTA contained 28,478 housing units, including 3,764 vacant units, yielding a 13.22% overall vacancy rate from those totals. Large multifamily structures accounted for 27,033 units, and renters represented 59.98% of occupied homes, which describes a renter-heavy, multifamily-dominant aggregate stock rather than the characteristics of any one building. There were 833 units recorded as vacant for rent, a category that is more relevant to rental availability than total vacancy but still not a count of live comparable listings. Seasonal, for-sale, held-off-market, and property-specific conditions can separate reported vacancy categories from the immediate choices facing a renter.
The rent history supports a stable-growth classification, although it remains backward-looking measurement rather than a forecast or investment recommendation. Exact same-month annualized ZORI changes were 5.82% over one year, 4.03% over three years, and 5.50% over five years. The latest direction therefore confirms the longer positive path and is stronger than both longer annualized comparisons rather than breaking from them. Data coverage was 100%, which reduces concern about gaps in this historical series. Annualized monthly-return variability of 2.45% shows that monthly movements occurred around the path, so one current rent snapshot deserves measured confidence rather than being treated as fixed. The historical maximum drawdown was 9.78%, a separate indication that the series has experienced meaningful declines. Transparent national discovery ranks were 370 for momentum, 608 for stability, and 110 for the balanced score, where lower ranks are higher; these are discovery tools, not forecasts or recommendations.
Redfin supplies a direct rolling-three-month ZIP resale observation, not rental transactions or rental comparables. Its median sold price was $514,884, up 11.93% year over year, with 385 homes sold and median marketing time of 59 days. Inventory stood at 483 homes, down 15.75% from a year earlier, while months of supply measured 3.8. Sale-to-list evidence was mixed rather than uniformly aggressive: the average sale-to-list ratio was 97.78%, 21.41% of sales closed above list, and 35.07% went off market within two weeks. Annualized ZIP ZORI divided by median sold price was 6.50%, but that is only a cross-source screening ratio, not a cap rate, net return, expected return, or property yield. The resale price increase exceeds the recent rent-history increase, while below-list average outcomes and longer marketing time complicate any simple tight-market reading; that tension challenges treating either sales or rents alone as decisive.
Several limits remain material. ZORI is a blended asking-rent index, ACS is a five-year survey of occupied renter homes, HUD is an administrative bedroom standard, and Redfin is a rolling resale observation; none measures the same transaction universe. The city, county, and metro figures remain context only, while ZCTA boundaries do not recreate USPS delivery geography. Before applying these aggregates to a property, verify the exact current asking rent, effective rent after concessions, lease length, utility responsibility, bedroom configuration, building-level comparable availability, and whether a listing is still active. For a resale-related check, confirm the specific property’s sale condition, list-price history, unit type, and relevant transaction details rather than applying the ZIP median mechanically. The practical unresolved question is whether those property-level facts agree with the broad ZIP signals or reveal that the aggregate snapshot is not a close match.
