The five-digit label 21216 is both a Zillow ZIP market identifier and the matched Census ZCTA. A ZCTA is a statistical area; it is not identical to a USPS delivery ZIP. In June 2026, Zillow ZORI for this ZIP was $1,687 per month, down 1.25% from the same month a year earlier. ZORI is a typical observed asking-rent index blended across rental types, rather than a bedroom-specific measurement or an ACS survey result. The immediate signal is therefore a current decline in the asking-rent indicator, while the longer history and the direct resale record introduce a different tension.
Redfin’s direct rolling-three-month ZIP resale observation—not rental transactions—recorded a median sold price of $184,958, 23.31% above its year-earlier value, with 86 homes sold. Median marketing time was 64 days. Inventory was 202 homes, equal to 7.1 months of supply; average sale-to-list was 102.03%, and 29.79% of sales were above list. These are for-sale indicators, not rental comparables. The price increase and above-list share sit alongside the supply and marketing-time measures, challenging a simple reading of the softer current asking-rent movement and not resolving the separate income screen. Annualized ZIP ZORI divided by median sold price is 10.95%, a cross-source screening ratio only, with no property-specific expenses or financing.
The direct Zillow history is backward-looking. Exact same-month annualized rent changes were 3.04% over three years and 5.58% over five years, yet the one-year retreat means recent direction breaks rather than confirms the longer path. The 4.14% annualized variability of monthly returns places less confidence in one current ZORI snapshot as a representative historical signal. Separately, the maximum drawdown reached 4.87%, documenting a past peak-to-trough decline rather than estimating a future one. Coverage is 98.32% across 117 observations. Transparent national discovery ranks among history-eligible ZIPs are 2,030 for momentum, 2,659 for stability, and 2,650 balanced, where lower ranks are higher. These measurements organize past behavior only, not forecasts or investment recommendations.
Source differences become material in the affordability screen. The matched ZCTA’s ACS 2024 five-year survey reports median gross rent of $1,176 for occupied renter homes, including selected utilities; that is 43.45% below the current Zillow asking-rent index. ACS median household income is $42,031. At the current index, the annual income required by a 30% screen is $67,480, and the index equals 48.16% of reported median household income. That 30% required-income screen is arithmetic, not advice and not an applicant qualification rule. Within the survey, 3,531 of 6,126 renter households were in the reported 30%-or-more burden group, or 57.64%. Neither burden nor the income screen establishes affordability for a particular home.
For a standardized bedroom sizing view, the local HUD ladder produces modelled monthly ZIP estimates of $1,237 for a studio, $1,373 for one bedroom, $1,687 for two bedrooms, $2,142 for three bedrooms, and $2,372 for four bedrooms. These are modelled estimates that scale ZIP ZORI using the local HUD ladder; they are never measured bedroom rents. HUD FMR/SAFMR is an administrative, bedroom-specific standard rather than an asking-rent observation. The local two-bedroom HUD standard is $1,857, placing the modelled two-bedroom estimate 9.15% below it. Numerical proximity between either series does not make either one a substitute for unit-level asking-rent evidence.
Housing stock data add a separate ZCTA-wide constraint. ACS records 15,580 housing units and 3,273 vacant units, an overall vacancy rate of 21.01%. The stock is recorded across single-family and large-multifamily structure classes, but those categories do not establish bedroom count, condition, utility treatment, or current asking rent for any dwelling. The total vacancy figure also spans more than units currently offered for rent. It should therefore be treated as an area-level occupancy measure, not proof that a specific home is available or that its terms will resemble the ZIP index.
For wider context, the Baltimore city scope’s current asking-rent index is $1,798.89, the Baltimore City county scope’s is $1,801, and the Baltimore-Columbia-Towson, MD metro scope’s is $1,936. Each broader figure exceeds the ZIP’s current index, but city, county, and metro values are context only rather than ZIP rental comparables. They cannot replace the ZIP-specific ZORI, matched-ZCTA ACS survey, or local HUD ladder. The comparison frames the ZIP as lower on this asking-rent measure than those wider scopes without showing why the difference exists or whether it applies to a particular property type.
The evidence should remain separated by universe: ZORI is a blended asking-rent index, ACS is a five-year survey of occupied renter homes, HUD is an administrative standard, and Redfin is direct ZIP resale evidence. Survey uncertainty, blended rental types, modelled bedroom scaling, and the resale-versus-rental distinction limit property-level conclusions. Concrete checks should verify an individual home’s advertised rent, bedroom count, utility treatment, physical condition, availability, lease terms, and comparable asks in the same property type. Resale records should likewise be checked for the individual property rather than projected onto rental terms. Does a specific home’s current ask, bedroom count, and utility treatment actually align with the mixed ZORI index and modelled ladder?
