In June 2026, ZIP 19711's Zillow ZORI is $2,283 per month, while the ACS 2024 five-year matched ZCTA reports median gross rent of $1,636, a 39.5% gap. The five-digit label is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. These measures should not be merged: Zillow ZORI is a typical observed asking-rent index blended across rental types, whereas ACS median gross rent is a five-year survey of occupied renter homes and includes selected utilities. The spread therefore identifies different populations and rent concepts, rather than a discrepancy that can be assigned to any given advertised home.
Rent history makes the current snapshot more nuanced. Exact same-month annualized ZORI changes were 4.3% over one year and 4.0% over three years, after 6.2% over five years. Thus recent direction confirms the longer upward path, but it breaks from—not reverses—the faster pace embedded in the five-year record. Annualized monthly-return variability was 3.4%, and maximum drawdown was -2.9%; these backward-looking measurements mean a current index reading is a useful observed level, not a fixed future quote. Coverage is 100% through the endpoint, supporting confidence that the series is continuous rather than sparsely sampled. Transparent national discovery ranks among history-eligible ZIPs were 557 for momentum, 2,157 for stability, and 1,063 for the balanced measure, where lower rank is higher. None are forecasts or investment recommendations.
Bedroom detail is a model, not a bedroom-rent observation. Scaling the ZIP ZORI by the local HUD ladder produces modelled monthly estimates of $1,759 for a studio, $1,921 for one bedroom, $2,283 for two, $2,732 for three, and $3,056 for four. The underlying HUD FMR/SAFMR ladder runs from $1,410 for a studio to $2,450 for four bedrooms. HUD FMR/SAFMR is an administrative, bedroom-specific standard, not asking rent; it supplies proportions for the model and does not measure what a current unit can command. Actual bedroom pricing can differ with property attributes, included costs, availability, and lease terms that these ZIP-level series do not report.
Income and burden offer a different lens, but not a unit-level eligibility test. The matched ZCTA's median household income is $95,403. Applying the arithmetic 30% required-income screen to the $2,283 ZORI yields $91,320 annually, or 28.7% of that area median; this screen is not advice and not an applicant qualification rule. In the ACS occupied-renter sample, 3,311 of 6,688 renter households, or 49.5%, reported gross-rent burdens at or above 30%. That share describes surveyed households and selected-utilities gross rent, not the financial condition of a prospective tenant or affordability of a particular listing. It nonetheless frames why a ZIP-wide asking-rent index and household experience can point to different pressures.
Housing counts point to a stock with multiple tenure and structure types rather than a pure apartment series. Of 20,515 housing units, 14,554 are single-family and 1,509 are in large multifamily structures. The ZCTA counted an 8.3% overall vacancy rate, including 759 units vacant for rent; renters occupy 35.5% of occupied homes. These are area-level counts, not a live inventory: a for-rent vacancy does not establish that a suitable home is available now, what its asking rent is, or whether its condition and lease terms fit a particular search. Likewise, occupancy and structure counts cannot identify quality, bedroom mix, concessions, or utility responsibility at one property.
The current Zillow ZIP index sits above each named wider benchmark, but scope matters: the Newark city-scope context is $2,113, the New Castle County county-scope context is $1,940, and the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD metro-scope context is $1,928. Those city, county, and metro values are context only, not alternate readings of the ZIP. The city figure reflects city scope, the county figure county scope, and the metro figure metro scope; none converts a broader-area average into a ZIP or property value. Their common directional contrast with the ZIP index is useful for orientation, while the source definitions, stock mix, and asking-versus-occupied-rent distinction keep them from being interchangeable.
Use this report as a ZIP-level comparison frame, not a quote, forecast, or recommendation. Before acting on any listing, verify the advertised monthly charge, exact bedroom count, address and ZIP assignment, availability date, lease length, required deposits and fees, utility inclusions, parking or other recurring charges, household-income method, and whether any subsidy or program standard applies. Ask whether the listing's rent is asking, effective after concessions, or a renewal amount, because the index, ACS survey, and HUD standard answer different questions. The practical unresolved question is simple: after those property-level checks, which rent definition most closely matches the home and lease actually under review?
