A cooling rent signal conflicts with firmer resale signals in ZIP 22311. Zillow’s typical observed asking-rent index, ZORI, was $1,806 in the stated June period, down 3.9% from the same month a year earlier, while the direct ZIP for-sale record points to materially stronger pricing. That split is the central decision tension: a current asking-rent snapshot has softened, but the available sale-market evidence does not mirror it. Neither reading converts into a forecast, a property valuation, or a transaction recommendation. The useful interpretation is narrower: leasing conditions summarized by ZORI should be evaluated separately from resale conditions summarized by Redfin.
The backward-looking ZORI path makes the recent decline more notable. The exact same-month one-year rent-history measure is -3.9%, whereas the three-year measure is +1.6% annualized and the five-year measure is +3.3% annualized. Thus, recent direction breaks from, rather than confirms, the longer positive path. History coverage is complete across 64 observations and 63 consecutive monthly returns. Annualized monthly-return variability is 2.6%, quantifying movement around the path and limiting the precision warranted for one current rent snapshot. Separately, maximum drawdown reached 4.5%, showing the largest cumulative retreat in the observed series. Transparent national discovery ranks among history-eligible ZIPs are 2,540 for momentum, 881 for stability, and 2,141 for the balanced measure; lower ranks are higher. These are retrospective sorting tools, not forecasts or investment recommendations.
The evidence sources answer different questions. Zillow ZORI is a ZIP-level, typical observed asking-rent index blended across rental types. By contrast, the matched Census ZCTA five-year survey reports median gross rent of $1,963, with a $71 margin of error, for occupied renter homes and includes selected utilities. That ACS figure is 8.0% above ZORI, a difference that should not be treated as a direct rent-comp gap. The five-digit 22311 label is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area, not the same thing as a USPS delivery ZIP. HUD’s two-bedroom standard is $2,160, placing ZORI 16.4% below it, but HUD FMR/SAFMR is an administrative bedroom-specific standard rather than asking rent.
The bedroom ladder is useful only as a modelled translation of the ZIP-wide index. Scaling ZORI with the local HUD ladder produces modelled monthly ZIP estimates of $1,580 for a studio, $1,605 for one bedroom, $1,806 for two bedrooms, $2,258 for three bedrooms, and $2,667 for four bedrooms. These are modelled estimates, never measured bedroom rents, and they do not establish what any particular available unit should command. Their value is internal consistency across bedroom sizes, while their limitation is that they inherit the ZIP index and HUD ladder rather than observed unit-level listings, lease terms, concessions, or utility treatment.
The affordability screen is comparatively tight even though the ZIP-wide asking index is below ACS gross rent. At a 30% required-income screen, $1,806 monthly asking rent implies $72,240 in annual income; this is arithmetic, not advice and not an applicant qualification rule. The matched ZCTA median household income is $87,626, making the ZIP asking-rent-to-income measure 24.7%. ACS also counts 6,868 renter-occupied homes, or 81.5% of occupied housing, and 3,454 renter households reporting rent burdens at or above 30%, equal to 50.3% of renters. The 8.6% vacancy rate, along with 4,092 large-multifamily units versus 1,730 single-family units, describes aggregate stock rather than availability or affordability at a particular unit. Neither burden nor vacancy proves conditions for an individual property.
Wider comparisons reinforce that this ZIP is a lower-rent pocket within the supplied contextual series, but those geographies are not substitutes for ZIP evidence: the Alexandria city context Zillow rent is $2,318, the Alexandria City county context Zillow rent is $2,284, and the Washington-Arlington-Alexandria, DC-VA-MD-WV metro context Zillow rent is $2,448. The city-context ACS median gross rent is $2,089, while metro-context apartment vacancy is 6.8%. These city, county, and metro values provide scale only; they cover broader populations and, in the ACS and apartment-vacancy cases, different measurement universes. They should not overwrite the ZIP’s cooling ZORI history, renter concentration, or local housing-stock composition.
Redfin supplies direct rolling-three-month ZIP resale evidence, not rental transactions. Its median sold price was $714,838, up 9.6% year over year, with 30 homes sold and median marketing time of 20 days. Active listings numbered 47, inventory was 18 homes and stood 52.3% higher than a year earlier, and months of supply were 1.9. Sale-to-list signals were also firm: the average sale-to-list ratio was 100.7%, 48.3% of sales closed above list, and 69.1% went off market within two weeks. This liquidity and price evidence challenges any simplistic reading that a falling asking-rent index alone means a uniformly weaker housing market. Annualized ZIP ZORI divided by median sold price is a 3.03% cross-source screening ratio only; it is not property-specific economics.
Several limits remain material. ZORI is an index rather than a quote for a specific home, ACS is a survey with sampling uncertainty and a different utility treatment, HUD is an administrative standard, and Redfin measures resale outcomes rather than rental performance. The periods also differ across the sources, so alignment should not be assumed. Before applying this report to a property, verify the actual asking rent, bedroom count, lease length, included utilities, concessions, availability date, and property condition; separately match resale observations to property type, sale timing, list history, and relevant transaction records. Those checks can test whether the ZIP-level tension is actually present in the property under review. Which documented lease terms and sale comparables truly match the specific home?
