Rent and resale evidence point to a meaningful split in this ZIP, making a single-market reading inadequate. In June 2026, Zillow's ZIP ZORI is $2,261 per month. ZORI is a typical observed asking-rent index blended across rental types, rather than a lease quote for a defined unit. The five-digit label 60618 is both Zillow's ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. That distinction matters when connecting the asking-rent index to the matched survey geography. The current ZORI is the ZIP's asking-rent anchor, while the separate direct resale observations below describe for-sale activity only.
The historical ZORI record through the supplied endpoint is backward-looking, not a forecast or investment recommendation. Exact same-month annualized ZORI change is 6.78% for the latest one-year comparison, 6.15% over three years, and 6.82% over five years. The latest reading is above the three-year pace and essentially in line with the five-year pace, so recent direction confirms rather than breaks from the longer growth path. The history has complete coverage. Its annualized monthly-return variability is 1.42%, which supports more confidence in one current index snapshot than a highly variable history would. The maximum observed drawdown is a separate 2.57% peak-to-trough decline. Transparent national discovery ranks among history-eligible ZIPs were 115 for momentum, 3 for stability, and 4 for the balanced score, where lower rank is higher.
Source definitions explain why rent figures do not align. In the matched ACS 2024 five-year ZCTA, median gross rent was $1,611; this is a survey estimate for occupied renter homes and includes selected utilities. The June Zillow asking-rent index is 40.35% higher, a cross-universe contrast rather than proof that any household or unit pays that gap. HUD FY2026 FMR/SAFMR is an administrative bedroom-specific standard, not asking rent. Scaling ZIP ZORI using the local HUD ladder produces modelled monthly estimates of $1,875 for a studio, $2,011 for one bedroom, $2,261 for two bedrooms, $2,909 for three bedrooms, and $3,363 for four bedrooms. These are modelled estimates, never measured bedroom rents.
The affordability screen is a calculation, not advice and not an applicant qualification rule. At a 30% rent-to-income threshold, the current monthly ZORI converts to required annual household income of $90,440. The matched ZCTA's ACS median household income is $106,384, yielding an asking-rent-to-income screen of 25.50%. Separately, ACS estimates that 6,607 of 18,876 renter households, or 35.00%, devote that threshold or more of income to gross rent; the 90% margin of error on that burdened-household count is ±753. This burden estimate describes surveyed renter households over the five-year ACS period and cannot establish affordability, payment history, or burden for a particular available unit.
Housing composition and vacancy are likewise ZCTA survey measures, not a live inventory feed. The ACS estimate contains 41,186 housing units and a 7.64% vacancy rate. Renters represent 49.62% of occupied homes. The stock includes 10,659 single-family units and 2,958 units in the supplied large-multifamily category, demonstrating that neither label captures every structure type by itself. Of the vacant stock, 933 units are classified vacant for rent. That category is not proof that a specific home is available, habitable, competitively priced, or suitable for a particular household. It instead frames the survey-based housing backdrop alongside the current Zillow index.
Wider comparisons place the ZIP index in context without replacing ZIP evidence: Chicago city context rent is $2,408.80, Cook County context rent is $2,336, and the Chicago-Naperville-Elgin, IL-IN-WI metro context rent is $2,275, each above the $2,261 ZIP ZORI. Chicago city, Cook County, and metro values are wider-geography context only, so they are not substitutes for a ZIP asking-rent observation or the matched ZCTA's household survey measures. The comparison establishes a broader rent backdrop, not a claim that a particular property shares city, county, or metro conditions.
The direct rolling-three-month ZIP resale observation ending June 30, 2026 reports a $699,842 median sold price, up 16.93% year over year. It records 310 homes sold with median marketing time of 36 days, 163 homes of inventory, and 1.6 months of supply. Sale-to-list signals were 105.20% on average and 68.50% of sales closed above list. These are for-sale/resale measurements, never rental transactions, rental comparables, or property economics. The resale price movement is much stronger than the recent ZORI gain, a tension that challenges any assumption that the rent history maps proportionally to sale pricing. Yet it confirms that the direct ZIP for-sale series, not Zillow or ACS, is where liquidity and sale negotiation signals belong.
Annualized ZIP ZORI divided by the Redfin median sold price equals a 3.88% cross-source screening ratio. It does not incorporate unit-specific operating costs, financing, taxes, condition, concessions, or the distinction between an asking-rent index and closed sales. Accordingly, it cannot resolve the tension between stable historical rent growth and faster reported resale-price growth. Relevant property-level checks include verifying that an address is in the relevant market and ZCTA match, obtaining the live asking rent and bedroom count, identifying included utilities and lease terms, inspecting current availability and condition, and reviewing applicable closed sales and listing records. Those checks remain necessary because ZORI, ACS vacancy and burden, HUD standards, and Redfin resale evidence all describe different measurement universes. The unresolved question is whether a specific unit's terms actually match any of these broad indicators.
