In June 2026, ZIP 19131 begins with a split signal: the current asking-rent index is rising while the direct ZIP resale series has a year-over-year decline. Zillow ZORI stands at $1,683 per month, 4.47% above its year-earlier reading. It is a typical observed asking-rent index blended across rental types, rather than the quoted rent for a standardized available home. This label is both a Zillow ZIP market identifier and a match to a Census ZCTA. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Those geography and measurement boundaries matter before using the current index as a unit-level comparable or blending it with a for-sale observation.
History supports an upward but nonuniform rental path. The exact same-month annualized ZORI changes are 4.47% over one year, 4.01% over three years, and 4.69% over five years. The latest direction therefore confirms, rather than breaks from, the longer positive path, although it trails the five-year pace. The history has 100% coverage. Annualized monthly-return variability is 3.29%, and the maximum drawdown was a 3.16% decline. Transparent national discovery ranks are 531 for momentum, 2,024 for stability, and 927 for the balanced measure, where lower ranks are higher. These are backward-looking measurements, not forecasts or investment recommendations; the variability and lower stability placement mean a single current rent snapshot deserves measured confidence.
The current ZORI and the survey rent deliberately answer different questions. In the matched Census ZCTA, the ACS 2024 five-year median gross rent is $1,375; it is a survey measure of occupied renter homes and includes selected utilities. The asking index is 22.4% above that median. This does not establish an error or a premium for any unit: one figure is a typical observed asking-rent index across rental types, while the other reflects surveyed occupied homes, different timing, a median calculation, and utility treatment. They are complementary benchmarks, not interchangeable rent comparables.
Bedroom comparisons require yet another evidence universe. The FY2026 HUD FMR/SAFMR ladder is an administrative bedroom-specific standard, not asking rent. Scaling ZIP ZORI with the local HUD bedroom ladder produces modelled monthly estimates of $1,300 for a studio, $1,412 for one bedroom, $1,683 for two bedrooms, $2,020 for three bedrooms, and $2,253 for four bedrooms. These are modelled estimates, never measured bedroom rents, and they do not show a unit’s availability, lease terms, utilities, condition, or concessions. Their value is a transparent size adjustment around the ZIP index rather than evidence that every home at a given bedroom count asks that amount.
Income and burden readings make the rent path harder to translate into household capacity. Annualizing the current index gives a $67,320 income screen at 30%, versus the ACS median household income of $48,393; the index-to-income arithmetic is 41.7%. The required-income screen is arithmetic, not advice or an applicant qualification rule. Separately, the ACS ZCTA estimates that 6,033 of 10,978 renter households, or 55.0%, paid at or above that threshold toward rent. That survey burden describes an area-level distribution, with survey uncertainty, and is not proof of affordability, payment history, or terms for a particular household or unit.
Stock adds context without converting vacancy into a leasing conclusion. The ZCTA reports 3,272 vacant housing units, a 14.21% vacancy rate, and a housing mix in which single-family units outnumber large multifamily units. These are area-level survey counts, not evidence that a particular unit is available, suitable, or negotiable. For wider context only, City of Philadelphia scope has a $1,813.93 context rent, Philadelphia County scope has a $1,814 context rent, and Philadelphia-Camden-Wilmington, PA-NJ-DE-MD metro scope has a $1,928 context rent; all three exceed the ZIP index. City, county, and metro figures remain wider-scope context rather than ZIP substitutes.
At the June 30, 2026 endpoint, Redfin’s direct rolling-three-month ZIP resale observation records a $212,452 median sold price, down 1.19% from a year earlier, with 86 homes sold and 59 median days on market. Its inventory measure is 155 homes and months of supply is 5.4. The average sale-to-list result is 97.68%, while 23.83% of sales closed above list. These are for-sale market and resale-liquidity signals, not rental transactions or rental comparables. The lower resale price and below-list average challenge a one-direction reading of the rising asking-rent history and income screen; the data do not identify a cause or resolve the difference.
One cross-source calculation is available but narrow: annualized ZIP ZORI divided by the Redfin median sold price equals 9.51%. This is a screening ratio only, not an estimate of property cash flow or transaction performance. It inherits the mismatch between an asking-rent index, a survey gross-rent benchmark, administrative HUD standards, and aggregate resale data. A property-level file would need current asking date, exact bedroom count, utility inclusions, concessions, lease length, physical condition, and directly comparable sale timing and characteristics. The unresolved question is whether a specific home’s documented terms can reconcile these separate benchmarks without assuming that any area-level measure applies to that home.
