In 20008, the June 2026 Zillow Observed Rent Index (ZORI) is $2,213 per month, 4.5% below its level a year earlier. ZORI is a typical observed asking-rent index blended across rental types, not a signed-lease comp, a property valuation, or a bedroom-specific quotation. The five-digit label 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 definition matters because the current index summarizes a broad ZIP market while subsequent survey, administrative-standard, and resale figures answer different questions.
The Zillow history, ending at the supplied June endpoint, is backward-looking rather than a forecast or investment recommendation. Its exact same-month 1-year change is -4.45%, against a 3-year annualized change of 0.06% and a 5-year annualized change of 2.80%. Thus the current decline breaks from the longer expansion and is more negative than the nearly flat intermediate path. Full 100% history coverage supports continuity. At 2.14%, annualized monthly-return variability has been limited, giving a reader somewhat more confidence that a single ZORI snapshot represents the series than a highly erratic series would; it does not make a point-in-time asking rent guaranteed. A separate 7.38% maximum drawdown shows the historical peak-to-trough retreat available in the record. The transparent national discovery placement was strongest for stability, rank 229, versus momentum rank 2,784 and balanced rank 1,972; lower ranks are higher. These measurements describe past observations only.
Resale evidence gives a sharper but distinct cooling signal. In Redfin’s direct rolling-three-month ZIP resale observation, the median sold price was $748,831, 14.42% below a year earlier. It recorded 120 homes sold and a median 42 days on market. Inventory was 124 homes, down 11.7% year over year, with 3.1 months of supply. The average sale-to-list ratio was 99.66%, while 30.8% sold above list. These are for-sale transactions, not rental transactions or rental comps. The annualized ZORI divided by median sold price is 3.55%, solely a cross-source screening ratio—not a cap rate, net return, expected return, or property yield. The price decline confirms the rent series’ recent cooling direction, but the near-list sale signal and recorded turnover challenge any one-direction reading of resale liquidity.
ACS and HUD should not be treated as alternate readings of the same asking-rent market. The matched Census ZCTA’s ACS 2024 five-year survey places median gross rent at $2,206, with an $87 margin of error, for occupied renter homes and includes selected utilities; it is a survey measure, not asking rent. It is therefore only descriptively close to ZORI. HUD’s FY2026 FMR/SAFMR uses administrative, bedroom-specific standards rather than observed asking rent; its local two-bedroom standard is $3,010. The monthly modelled bedroom estimates scale ZIP ZORI using the local HUD ladder: $1,926 for a studio, $1,985 for one bedroom, $2,213 for two bedrooms, $2,794 for three bedrooms, and $3,286 for four bedrooms. These are modelled estimates, never measured bedroom rents, and they do not establish what any available unit is priced at.
Income and burden data supply another lens but remain ACS ZCTA aggregates. Median household income is $125,212, with a $10,958 margin of error, and the cross-source ZIP asking-rent-to-income comparison is 21.2%. Annualizing the current index produces an $88,520 required-income figure under a 30% screen. That required-income screen is arithmetic, not advice and not an applicant qualification rule. In the ACS survey, $4,534 of $10,691 renter households fall in the burden group at or above that threshold, a 42.4% share. This does not prove that an individual apartment is affordable or unaffordable, nor does an aggregate burden share identify the utility treatment, household size, rent, or income of a particular occupant.
The housing survey profile is renter-led rather than owner-dominated. ACS reports 18,058 housing units and an extensive large-multifamily component; its renter share is 63.6%, and its aggregate vacancy rate is 6.9%. Those are stock and survey-vacancy measures, not evidence that a specific unit is vacant or available for rent. For wider-geography context only, the Washington city context reports a $2,532 rent reading, the District of Columbia county context has $1,954 median gross rent, and the Washington-Arlington-Alexandria, DC-VA-MD-WV metro context has a $2,448 rent reading. These city, county, and metro comparisons are not substitutes for a ZIP ZORI, a matched-ZCTA survey, or an address-level observation.
The decision tension is not simply a rent decline or a sale-price decline. The backward-looking rent path has shifted negative after a positive longer comparison, while the direct resale price change is substantially negative in its own sales universe. At the same time, survey gross rent and the asking-rent index are close in level despite different timing and utility treatment, and the income screen differs from the reported burden share because one is a ZIP-wide arithmetic ratio while the other summarizes surveyed renter households. Lower-than-context rent readings coexist with a renter-heavy housing stock and survey vacancy measure, yet none establishes causation, a rent concession, or the economics of a particular building. The appropriate weight on the current ZORI is therefore tempered by both the relatively stable historical series and the fresh negative direction.
Several limits prevent these aggregates from becoming a property conclusion. Zillow is a monthly asking-rent index; ACS is a multiyear survey with its own sampling uncertainty and selected-utility definition; HUD is a fiscal-year administrative standard; and Redfin is a rolling for-sale observation. Their dates, populations, and transaction types do not align. Concrete address-level checks would include the actual advertised rent, bedroom count, utilities included, lease term, availability status, applicable ZIP and ZCTA boundary, and any contemporaneous listing and closed-sale facts. Those checks are especially important where the modelled bedroom ladder and the resale screen diverge from an actual unit. For the address under review, do its rent terms and sale/list facts resemble the aggregates closely enough for this ZIP-level comparison to be relevant?
