The 22193 label is both a Zillow ZIP market identifier and a Census ZCTA match. In June 2026, Zillow’s typical observed asking-rent index, ZORI, which blends rental types, stood at $2,273 and was 2.58% above a year earlier. The immediate tension is not a falling index but a cooling pace of rent change alongside firmer resale pricing. ZORI is a broad ZIP-level asking-rent benchmark, not a signed-lease quote, a measured bedroom rent, or a prediction for any individual home. Because it blends listings across unit sizes and rental forms, its movement can differ from the movement at a specific address.
That tension is visible in Redfin’s direct rolling-three-month ZIP for-sale/resale observation. Its median sold price was $534,879, 1.88% higher year over year; 266 homes sold with a median 33 days on market. Inventory measured 169 homes, up 25.97%, while months of supply stood at 1.9. The average sale-to-list result was 100.28%, and 45.60% of sales closed above list. Together these are direct resale-liquidity and price signals. They describe for-sale transactions and their marketing conditions, not rental transactions or rent comparables. The combination supplies direct turnover and listing-outcome measures, but offers no evidence about landlord concessions, lease renewals, or advertised rents.
Read together, the resale evidence complicates a simple cooling story: price growth and above-list activity confirm continued price pressure in the for-sale universe, whereas rising inventory tempers that reading. Annual ZORI divided by Redfin’s median sold price equals a 5.10% cross-source screening ratio. It is not a cap rate, net return, expected return, or property yield, because it does not measure operating costs, financing, taxes, repairs, actual unit rent, or unit-specific vacancy. The tension is therefore real but cross-universe: resale pricing has been firmer than the slowing rent-growth path suggests. It compares broad measures from distinct sources and cannot link the ZORI observation to the individual properties that sold.
ZORI’s backward-looking history explains why “cooling” is more accurate than “declining.” Exact same-month annualized asking-rent changes were 2.58% over 1 year, 4.69% over 3 years, and 6.29% over 5 years. The latest direction breaks from the faster long-run path, without erasing it. Annualized monthly-return variability of 2.88% means a single current index point warrants less precision than its dollar figure can imply. Separately, the maximum peak-to-trough drawdown was 3.10%, evidence that the series has experienced reversals. With 99.28% coverage, these metrics describe observed history only; they are not a forecast or investment recommendation. Underlying readings are direct Zillow ZIP observations through the stated endpoint.
The series’ transparent national discovery ranks among history-eligible ZIPs were 788 for momentum, 1,412 for stability, and 772 for the balanced measure; lower ranks are higher. They are discovery aids rather than a national forecast or a quality grade. Near-complete history coverage gives the trend record more evidentiary continuity, while the distinct variability and drawdown measures caution against assuming that the June ZORI snapshot applies evenly across property types, lease terms, or listing conditions. No total number of history-eligible ZIPs is supplied, so a rank cannot be converted to a percentile.
Definitions matter before comparing rent figures. The matched Census ZCTA—a statistical area, not identical to a USPS delivery ZIP—reported 2024 ACS five-year median gross rent of $1,890. ACS is a survey of occupied renter homes and includes selected utilities, whereas ZORI is an asking-rent index; the current asking level is 20.26% above the ACS median. For broader context, Woodbridge city context had a $2,194.54 rent measure, Prince William County context had $2,282, and the Washington–Arlington–Alexandria, DC–VA–MD–WV metro context had $2,448; each has a wider geographic scope than this ZIP and is not a substitute for it.
HUD FY2026 FMR/SAFMR is an administrative, bedroom-specific standard rather than asking rent. Applying its local bedroom ladder proportionally to ZIP ZORI yields modelled monthly estimates—not measured bedroom rents—of $1,978 for a studio, $2,044 for one bedroom, $2,273 for two bedrooms, $2,874 for three bedrooms, and $3,377 for four bedrooms. This ladder is a scaling device built from the local HUD standard. It does not establish what any available unit is asking, which utilities are included, or whether a listed home is comparable to the blended ZORI. Nor does it convert the administrative standard into an observed rent series.
The 30% required-income screen is arithmetic, not advice or an applicant-qualification rule: applying it to $2,273 produces $90,920 in annual income, below the matched ZCTA’s $117,337 median household income. Yet ACS reports that 50.64% of renter households spend 30% or more of income on rent, a population measure that cannot prove affordability for a particular household or unit. The ZCTA had 24,945 housing units, a 2.25% vacancy rate, and 22,334 single-family units; neither the aggregate vacancy nor the burden rate establishes the availability or economics of one listing. At property level, verify the current asking rent, bedroom count, included utilities, recurring mandatory charges, lease term, availability, and actual unit condition before using any ZIP benchmark. An address-specific arithmetic comparison would require the verified monthly obligation and household income, neither of which is supplied by these area aggregates.
