The five-digit label 98513 is both Zillow’s ZIP market identifier and a matched Census ZCTA. A ZCTA is a Census statistical area and is not identical to a USPS delivery ZIP. Zillow’s reported ZIP ZORI is $2,409, up 3.6% from the same month a year earlier. This is a typical observed asking-rent index blended across rental types, rather than a quoted rent for every available home. By contrast, the matched ACS five-year survey reports median gross rent of $1,967 for occupied renter homes, including selected utilities. The asking-rent index therefore sits 22.5% above that survey median, a meaningful difference in source universe rather than evidence that every renter is paying the current asking level.
The backward-looking rent path is positive but has moderated slightly relative to its longer run. The one-year same-month annualized change was 3.6%, the three-year measure was 3.7%, and the five-year measure was 4.7%. Thus, recent direction confirms the broader growth path, while trailing the stronger five-year pace. Only 1.9% annualized monthly-return variability supports more confidence in the stability of a single current ZORI snapshot than a highly erratic series would. Separately, the worst peak-to-trough drawdown was 1.2%, a shallow historical setback. Coverage is complete across 65 observations. In the national history-eligible ZIP discovery universe, the momentum rank is 721, stability rank is 63, and balanced rank is 108; these are transparent discovery measures, not forecasts or investment recommendations.
Bedroom figures should be read as modelled estimates, not measured bedroom rents. The local HUD FY ladder spans from $1,538 for a studio standard to $3,288 for a four-bedroom standard. Scaling the ZIP ZORI by that local HUD ladder produces modelled monthly estimates of $1,890 for a studio, $2,067 for one bedroom, $2,409 for two bedrooms, $3,212 for three bedrooms, and $4,041 for four bedrooms. HUD fair-market-rent or small-area standards are administrative, bedroom-specific benchmarks; they are not asking-rent observations. The ladder is useful for imposing a locally consistent bedroom relationship on the ZIP-wide index, but it does not replace property-level rental evidence.
At the arithmetic 30% required-income screen, a household would need $96,360 in annual income to place the $2,409 monthly asking-rent index at that threshold. The ZCTA’s ACS median household income is $113,053, and the ZIP asking-rent-to-income calculation equals 25.6%. Neither statistic is advice, an applicant qualification rule, or proof that a particular home is affordable. The ACS burden data point to a separate occupied-renter universe: 1,243 of 2,804 renter households, or 44.3%, reported spending at least 30% of income on gross rent. That burden measure includes existing occupied households and selected utilities, so it cannot be assigned to a specific advertised unit or used as a direct reading of current applicant capacity.
The ZCTA survey describes a housing base of 14,479 units and a 5.7% vacancy rate. Its structure mix includes 12,015 single-family units and 92 units in large multifamily structures, while 144 vacant units were classified as for rent. Those counts characterize survey-period stock and vacancy categories, not a live inventory of available rentals. They also do not show lease terms, turnover, concessions, unit condition, or bedroom mix. The stock data nevertheless frame the earlier rent comparisons: a ZIP-level blended asking-rent index operates across a housing base whose measured structure composition is heavily weighted toward single-family units, while the available-rental count requires direct listing verification.
Wider geography provides context but should not replace the ZIP observations. The City of Olympia context rent is $2,013, while the Thurston County context rent and Olympia-Lacey-Tumwater, WA metro context rent are each $2,084; each is a broader-geography comparison rather than a ZIP measurement. The ZIP’s current asking-rent index is therefore above all three contextual rent figures. At City of Olympia scope, the ACS renter burden share is 59.6%, versus 55.4% at Thurston County scope. Those city and county values describe their own resident and housing universes. They suggest that the ZIP’s lower burden share relative to these contexts should be interpreted alongside its different income, tenure, and survey composition rather than as a direct unit-level affordability conclusion.
Redfin supplies a different, direct rolling-three-month ZIP resale observation, not rental transactions. In that for-sale market, median sold price was $519,883, down 1.2% year over year, with 165 homes sold and a median 22 days on market. Inventory stood at 172 homes, up 35.5%, and months of supply were 3.2. Average sale-to-list was 99.5%, while 23.2% of sales closed above list price. These liquidity and price signals stay within the ZIP resale universe: they do not provide rental comps or operating economics. Annualized ZIP ZORI divided by the Redfin median sold price produces a 5.6% cross-source screening ratio only, not a cap rate, net return, expected return, or property yield. The resale evidence creates a notable tension with rent history: asking rents have continued rising, while the observed sold-price measure declined and inventory expanded.
The evidence has several practical limits. ZORI is an index rather than a unit quote; ACS is a five-year survey with sampling uncertainty; HUD is an administrative standard; and Redfin reflects completed ZIP resale activity over a rolling period. None establishes lease economics, tenant eligibility, property condition, repairs, financing, taxes, insurance, utilities, or the timing of a specific listing or sale. A property-level review would need current same-bedroom asking listings, effective rent after concessions, lease duration, included utilities, unit size and condition, and directly comparable nearby sale records with sale dates and property characteristics. The central unresolved question is whether a particular home’s current lease and physical attributes align with the ZIP-level index and the separate resale signals.
