The immediate tension in 20902 is that the June 2026 Zillow ZORI stood at $2,038 per month while its year-over-year change was only 1.1%, even as the local resale evidence showed much faster price movement. Zillow ZORI is a typical observed asking-rent index blended across rental types, not a lease-level comparable set or a measure of every available unit. Here, the five-digit label is both Zillow’s ZIP market identifier and a Census ZCTA match, which permits useful but carefully bounded comparisons across the supplied sources.
For wider-context comparison, Silver Spring city asking rent was $1,966, Montgomery County asking rent was $2,346, and the Washington-Arlington-Alexandria, DC-VA-MD-WV metro asking rent was $2,448; each is a broader-scope context value rather than a ZIP observation. The ZIP is above the city figure but below the county and metro figures. The matched Census ZCTA’s ACS 2024 five-year median gross rent was $2,116, or 3.7% above the current asking-rent index. ACS median gross rent is a five-year survey measure of occupied renter homes that includes selected utilities. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP.
The rent path has decelerated: exact same-month annualized change was 1.1% over one year, 2.1% over three years, and 4.0% over five years. Thus, the latest pace breaks from the stronger longer-run growth path rather than confirming it. The historical series has complete coverage across its available monthly observations. Annualized monthly-return variability reached 2.5%, so individual monthly readings have moved around the broader trend. Its largest historical peak-to-trough decline was 3.3%, a bounded backward-looking drawdown rather than a forecast. The transparent national discovery ranks among history-eligible ZIPs were 599 for stability, 1,712 for momentum, and 1,125 for the balanced measure, with lower ranks stronger. This record supports more confidence in a current snapshot than a sparse series would, but slowing growth still limits what one reading can imply.
The bedroom figures are modelled monthly ZIP estimates created by scaling ZIP ZORI with the local HUD bedroom ladder, never measured bedroom rents: $1,774 for a studio, $1,825 for one bedroom, $2,038 for two bedrooms, $2,575 for three bedrooms, and $3,027 for four bedrooms. The HUD two-bedroom standard is $2,390, placing the all-type ZIP asking index 14.7% below that benchmark. HUD FMR or SAFMR is an administrative, bedroom-specific standard, not an asking-rent observation; it supplies the ladder’s relative sizing rather than proof of a unit’s attainable rent.
At the current asking-rent index, the 30% required-income screen produces $81,520 in annual household income. This is arithmetic, not advice and not an applicant qualification rule. That screen is below the ZCTA’s $114,486 median household income, while the ZIP asking-rent-to-income screen is 21.4%. Yet ACS reports 6,497 renter households and 2,866 households spending at least 30% of income on gross rent, a 44.1% burden share. That burden statistic describes surveyed occupied renter homes and cannot establish the cost pressure, utility treatment, or eligibility of any particular available unit.
The ACS ZCTA counted 19,031 housing units, with a 4.2% vacancy rate and renters accounting for 35.6% of occupied homes. Housing stock was led by 13,019 single-family units, alongside 3,109 units in larger multifamily structures. Those counts describe the surveyed area’s housing composition, not a current listing pool. Similarly, vacancy is not proof that a specific home can be rented, at what rent, or on what terms; it includes units whose status and timing may not match an active renter search.
Redfin’s direct rolling-three-month ZIP resale observation belongs strictly to the for-sale market, not to rental transactions. Median sold price was $604,863, up 11.0% from a year earlier; 92 homes sold and median marketing time was 29 days. Inventory measured 85 homes, up 30.7%, while months of supply stood at 2.8. Sale-to-list evidence remained firm, with an average ratio of 101.5%, 54.0% of sales above list, and 63.3% off market within two weeks. The annualized ZIP ZORI divided by median sold price is 4.04%, a cross-source screening ratio only, not a cap rate, property yield, net return, or expected return. Resale price appreciation and prompt selling challenge the muted recent rent-growth signal, while rising inventory tempers any simple reading of resale tightness.
The evidence is strongest as a source-separated screen rather than a property conclusion. Confirm the subject address’s actual bedroom count, current asking rent, concessions, lease term, included utilities, condition, and availability date before comparing it with the modelled ladder or ACS gross-rent measure. For a resale comparison, verify the property type, sale date, list-price history, and whether reported inventory aligns with the relevant segment. These checks address the central limitation: ZIP rent indices, ZCTA surveys, HUD standards, and rolling resale statistics each answer different questions and none forecasts rent, sale price, or a particular property outcome.
","findings":[{"body":"The current ZIP asking-rent index increased only 1.1% over the latest same-month year, versus stronger annualized gains over the three- and five-year windows.
