At the 2026-06 reading, Zillow ZIP ZORI for this ZIP is $2,535 per month, up 2.94% from the matching month a year earlier. The Pasadena city context is about $2,535, while the Anne Arundel County context is $2,370 and the Baltimore-Columbia-Towson, MD metro context is $1,936; all three are wider-area context rather than substitutes for the ZIP reading. ZORI is a typical observed asking-rent index blended across rental types. It is not a unit-specific advertised quote, an executed lease rent, or a claim that every property in the ZIP asks the index level. The near-city alignment alongside higher ZIP-than-county and ZIP-than-metro readings frames the current local index without establishing a reason for the differences.
The direct ZORI series through the stated endpoint recorded exact same-month annualized changes of 2.94% over one year, 3.13% over three years, and 5.94% over five years. Thus, the newest direction continues the longer upward path, but it does not confirm the faster rate embedded in the longer windows. Annualized monthly-return variability was 3.08%, and maximum drawdown was -3.01%; those backward-looking measures mean a single current observation merits more caution than a perfectly steady series would. Coverage was 99.12%, supporting continuity rather than certainty. In the supplied national discovery comparison of history-eligible ZIPs, momentum ranked 950, stability ranked 1,750, and balanced ranked 1,229, with lower rank higher. These ranks and historical rates are retrospective measurements, not forecasts or investment recommendations.
The shared label needs careful interpretation. The 21122 label is both a Zillow ZIP market identifier and a matched Census ZCTA label. A ZCTA is a statistical area, not identical to a USPS delivery ZIP. The ACS 2024 five-year survey places median gross rent at $2,108, with a $99 margin of error, among occupied renter homes in that ZCTA; its gross-rent concept includes selected utilities. Current ZORI is 20.3% above that survey median, but this is a source-universe gap, not a contradiction or a measure of appreciation. Zillow’s index represents typical observed asking rents across rental types, whereas ACS summarizes occupied renter households over a survey period. Different populations, definitions, utility treatment, and timing prevent either measure from validating a specific listing.
Bedroom detail is a modelling exercise, not a set of measured ZIP rents. Scaling ZIP ZORI by the local HUD ladder produces modelled monthly estimates of $1,859 for a studio, $2,063 for one bedroom, $2,535 for two bedrooms, $3,219 for three bedrooms, and $3,564 for four bedrooms. For comparison, the FY2026 HUD FMR/SAFMR ladder is $1,362, $1,511, $1,857, $2,358, and $2,611 in the same bedroom order. The resulting two-bedroom model is 36.5% above its HUD reference. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent; scaling it only supplies a transparent local ratio pattern, not evidence about available units or achieved bedroom rents.
Affordability comes with a different internal tension. At the current index, the 30% required-income screen produces $101,400 in annual household income, compared with a ZCTA median household income of $127,587; asking rent therefore represents 23.8% of that median-income benchmark. This is arithmetic based on annualizing the index, not advice and not an applicant qualification rule. Separately, ACS reports 1,430 of 2,999 occupied renter households as spending at least that threshold share on gross rent, or 47.7%. That broad burden share is relevant context for renter-household exposure, but it cannot establish the budget, lease terms, utilities, or burden status of a particular applicant or unit. The income and burden data are survey results, while the current ZORI is an asking-rent index.
The matched ZCTA’s ACS stock profile lists 23,675 housing units, a 5.29% vacancy rate, and a 13.37% renter share. This points to an owner-dominant housing stock with a smaller renter component, but it does not identify how many listings are currently marketed, fit a given household, or carry the ZORI rent. Vacancy categories are counts and status classifications, not proof of concession, condition, availability, or bargaining room for a particular unit. They must also stay separate from the metro apartment-vacancy context, which is a different geography and housing measure. The city, county, and metro rent comparisons above are context only and should not be merged with these ZCTA stock measures.
Decision use rests on reconciling the listing with the correct evidence universe rather than treating any headline as a quote. Confirm the property’s asking rent, bedroom and bathroom classification, address and geography, lease term, utility responsibility, recurring fees, concessions, availability date, and whether advertised rent is conditional. Compare those facts with ZORI as an index, ACS as a survey median, and HUD as an administrative standard. Check the actual listing and lease rather than assuming a modelled bedroom figure, a vacancy category, or an area burden statistic describes the property. The practical closing question is: do the property-level terms match the rental concept being compared, and are all charges visible before relying on the ZIP-level context?
