In 21209, Zillow’s ZIP asking-rent index for June 2026 is $1,853 per month, up 5.2% year over year. This is a typical observed asking-rent index blended across rental types, rather than a rent quote for a specific available unit. Backward-looking same-month history shows annualized changes of 5.1% over one year, 3.7% over three years, and 4.7% over five years. Recent growth therefore confirms, and modestly exceeds, the longer growth path rather than breaking from it. The annualized monthly-return variability measure is 2.7%, indicating relatively limited historical month-to-month movement. Separately, the deepest historical drawdown was 4.3%, so a current rent snapshot should be treated as a current index reading, not a fixed floor. History coverage is 98.5%.
The history record is categorized as stable growth, but its discovery measures should remain descriptive rather than predictive. Among history-eligible ZIPs, 21209 ranks 483 on momentum, 1,059 on stability, and 324 on the balanced measure; lower ranks indicate stronger placement in each transparent national discovery screen. The stronger balanced placement reflects a history that combines sustained gains with comparatively contained variability, while the weaker stability rank cautions against treating the recent path as perfectly smooth. These are backward-looking Zillow ZIP ZORI measurements, not forecasts, investment recommendations, or evidence of future rent performance. The limited variability supports somewhat more confidence in the representativeness of one current index reading than a highly volatile series would, but the prior drawdown still establishes meaningful historical movement.
Bedroom figures are modelled estimates created by scaling the ZIP ZORI through the local HUD bedroom ladder; they are not measured bedroom asking rents. The resulting monthly range runs from $1,359 for a studio to $2,605 for a four-bedroom, with a modelled two-bedroom estimate of $1,853. That two-bedroom estimate closely tracks the local HUD two-bedroom standard of $1,857. HUD FMR or SAFMR values are administrative, bedroom-specific standards rather than market asking rents, and their alignment here should not be read as proof that available two-bedroom listings lease at the modelled figure. The ladder is most useful for keeping unit-size comparisons internally consistent when reviewing property-level listings, lease terms, and stated utility treatment.
The five-digit label is both Zillow’s ZIP market identifier and the match for the Census ZCTA, but a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. In the matched ACS 2024 five-year survey, occupied renter homes had a median gross rent of $1,655 with a $62 margin of error; gross rent includes selected utilities and is not an asking-rent series. The current asking-rent index is therefore about 12% above that occupied-renter benchmark. Applying a 30% income screen to the $1,853 index produces required household income of $74,120, versus ZCTA median household income of $91,437. That 24.3% asking-rent-to-income calculation is arithmetic only, not advice or an applicant qualification rule. Even so, 50.3% of surveyed renter households reported spending at least 30% of income on rent, showing that aggregate income and a typical rent screen do not settle household-level affordability.
The matched ZCTA contains 12,071 housing units, and its overall vacancy rate is 3.7%. Renters occupy 42.5% of occupied homes, making the area neither exclusively renter-oriented nor exclusively owner-oriented in the ACS stock mix. Of the vacant stock, 257 units were classified as for rent, a category that is informative about the survey’s stock composition but does not establish that any particular unit is available, competitively priced, or comparable with Zillow’s blended index. Housing counts, renter share, and vacancy are ACS survey measures for the ZCTA universe. They should not be used to infer the condition, lease-up status, concessions, or turnover timing of a specific building or apartment.
Wider geographies provide useful but non-substitutable context: Baltimore city’s asking-rent context is $1,799, Baltimore County’s asking-rent context is $1,728, and the Baltimore-Columbia-Towson metro asking-rent context is $1,936. Thus, the ZIP’s $1,853 Zillow index sits above the named city and county contexts while remaining below the named metro context. Those city, county, and metro figures are wider-market context only; none is a ZIP estimate, a direct substitute for the ZCTA ACS gross-rent measure, or a property comp. The contrast also reinforces the source distinction: a Zillow asking-rent index, ACS gross rent for occupied renter homes, and HUD administrative standards can move differently because they describe different populations and measurement purposes.
The direct rolling-three-month ZIP resale observation describes the for-sale market, not rental transactions. Median sold price was $432,402, up 0.6% year over year, with 68 homes sold and a median 33 days on market. Active listings numbered 127, inventory was 62 homes, and inventory increased 13.4% from a year earlier; months of supply stood at 2.8. Average sale-to-list was 99.4%, while 28.8% of sales closed above list and 54.7% went off market within two weeks. Annualized ZIP ZORI divided by median sold price equals a 5.14% cross-source screening ratio only, not a cap rate, net return, expected return, or property yield. The central tension is that the rent index and its recent history strengthened more quickly than resale prices, while resale inventory increased; limited supply and near-list sale pricing partially challenge any simple interpretation of a weak for-sale market.
Several limits remain material. Zillow ZORI is a blended typical asking-rent index, ACS is a survey of occupied renter homes, HUD is an administrative standard, and Redfin reports ZIP resale activity; none alone establishes the economics of a particular property. A property-level review should verify the exact address and delivery geography, current advertised rent, bedroom count, square footage, lease length, included utilities, concessions, availability date, and property condition. For resale comparisons, the relevant checks are recent sale dates, property type, condition, listing history, final sale terms, and whether the comp is genuinely comparable. The evidence supports a structured comparison of rent, household burden, stock, and resale signals, but it does not establish a future path or a conclusion about any individual unit.
