The central measured tension is a $3,463 monthly ZIP asking-rent index beside a $1,574,644 resale median: annualized ZIP ZORI divided by that sale price is only a 2.64% cross-source screening ratio. In June 2026, Zillow’s ZIP ZORI describes typical observed asking rent blended across rental types, while the resale figure belongs to the for-sale market. Those figures can sit in the same ZIP without measuring the same homes, transactions, or costs. The rent index is therefore useful as a current asking-rent snapshot, but its relationship to resale pricing should not be treated as unit-level economics.
The backward-looking rent path remains positive but has moderated relative to its longer record. The exact same-month one-year annualized change was 3.6%, versus 4.9% over three years and 5.9% over five years. Recent direction therefore confirms continued rent growth, yet breaks from the faster pace embedded in the longer path. History has complete coverage across 78 observations. Variability of 3.7% in annualized monthly returns means a single current rent snapshot deserves measured confidence rather than unquestioned precision; monthly movements have not been uniform. Separately, the worst historical peak-to-trough drawdown was 3.7%, showing that the series did experience reversals even during a positive multiyear record. Transparent national discovery ranks among history-eligible ZIPs were 555 for momentum, 2,392 for stability, and 1,279 for the balanced measure, where lower rank is higher. These are historical measurements, not forecasts or investment recommendations.
The five-digit label 22207 is both a Zillow ZIP market identifier and a Census ZCTA match; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. That distinction matters because ACS 2024 five-year data describe occupied renter homes in the matched ZCTA, not current advertised units. Its median gross rent was $2,274 and includes selected utilities, whereas Zillow measures asking rent. The ZIP asking-rent index was 52.3% above that ACS median. HUD’s FY2026 two-bedroom standard was $2,650; HUD FMR or SAFMR is an administrative bedroom-specific standard, not asking rent. These are complementary evidence universes rather than interchangeable rental comparables.
The bedroom figures are modelled estimates created by scaling ZIP ZORI with the local HUD ladder, not measured bedroom rents. The resulting monthly ladder is $3,006 for a studio, $3,110 for one bedroom, $3,463 for two bedrooms, $4,365 for three bedrooms, and $5,136 for four bedrooms. It provides a transparent size-based way to organize the ZIP-level rent index, but it cannot establish the advertised rent of a particular floorplan, building, condition level, or lease. The HUD ladder supplies the relative bedroom scaling; it does not convert these estimates into observed bedroom-specific asking-rent transactions.
At a 30% rent-to-income screen, the current ZIP asking-rent index implies $138,520 in required annual income. The matched ZCTA’s median household income was $245,745, producing a 16.9% asking-rent-to-income comparison, but that arithmetic is not advice and is not an applicant qualification rule. The ACS renter burden measure adds a different household-level lens: 45.8% of renter households, or 1,179 of 2,574, reported spending at least 30% of income on gross rent. In city context, Arlington’s rent index was $2,722; in Arlington County context it was also $2,722; and in Washington-Arlington-Alexandria metro context it was $2,448. Those city, county, and metro figures are wider-geography context, not substitutes for the ZIP reading.
The matched ZCTA’s housing stock was more owner-oriented than the broader Arlington context. ACS counted 12,837 housing units and 606 vacant units, a 4.7% vacancy rate, while renters represented 21.0% of occupied households. The structure count included 10,837 single-family units and 1,174 units in larger multifamily structures. ACS also recorded 23 vacant units for rent. Because these are survey-based stock and vacancy measures rather than live listings, neither the vacancy rate nor the vacant-for-rent count proves availability, pricing, condition, or concessions for a particular unit. Likewise, the burden result does not establish affordability for any individual household or property.
Redfin’s direct rolling-three-month ZIP resale evidence describes for-sale activity only, not rental transactions. Median sold price was $1,574,644, up 5.15% year over year, with 126 homes sold and a median 11 days on market. Redfin reported inventory of 97 homes and 2.3 months of supply. Sale-to-list evidence was firm: the average sale-to-list ratio was 102.26%, 50.45% of sales closed above list, and 63.16% went off market within two weeks. This resale liquidity and price movement confirm that the ZIP’s for-sale observations were active, but they challenge any simple extension from resale strength to rental acceleration because one-year ZORI growth was slower than the three-year and five-year rent-history measures. The screening ratio remains only a cross-source screen, not a measure of property operations or expected results.
Key limits stem from timing, geography, and definition. Zillow is a blended asking-rent index; ACS is a five-year ZCTA survey of occupied homes; HUD is an administrative standard; and Redfin is a direct ZIP resale observation. None supplies a verified rent roll, lease concession record, utility bill, maintenance profile, or property-specific sale comparison. A property-level review can confirm the precise delivery ZIP and market ZIP, current advertised rent and concessions, bedroom count, included utilities, lease term, occupancy status, physical condition, and whether a sale record is comparable in property type and date. Those checks determine whether these distinct datasets meaningfully apply to the specific home being examined.
