For ZIP 83646, the immediate decision question is how to frame a current market-wide rent signal without treating it as the price of a specific available home. Zillow’s Observed Rent Index (ZORI) is $2,338 in June 2026, after a 3.4% year-over-year increase. It is a typical observed asking-rent index blended across rental types, so it provides a current ZIP market reference rather than a lease quote, a utility-inclusive payment, or evidence that every bedroom size follows the same price. The useful comparison is therefore between distinct measures: a current asking-rent index, a survey measure of occupied renter homes, and an administrative benchmark—each answering a different decision question.
Measurement choice is central here. In the matched Census ZCTA, the ACS 2024 five-year median gross rent is $1,892. This is a five-year survey estimate for occupied renter homes and includes selected utilities; it is not a current asking-rent series. Zillow’s $2,338 index is $446, or 23.6%, higher, a difference that describes measure and timing rather than a conversion from one universe to the other. Separately, the FY2026 two-bedroom HUD FMR/SAFMR standard is $1,655. HUD FMR/SAFMR is an administrative bedroom-specific standard, not asking rent, and the ZIP index is 41.3% above that standard; the gap does not establish a market overcharge or a likely contract rent.
The income and renter evidence adds a separate household lens. The ACS ZCTA median household income is $102,861; it describes all households in the survey geography, not a renter-income median. A $93,520 annual income at the 30% screen is arithmetic based on the ZIP index, not advice or an applicant qualification rule. That screen equals 27.3% of the reported median household income. Renters occupied 5,335 homes, representing 19.8% of occupied homes. Of the renter-household burden observations, 2,422 met or exceeded that threshold, or 45.4%. This observed ACS burden describes aggregated households and cannot prove the payment stress, eligibility, or budget of a particular renter or unit.
The bedroom view is deliberately constructed, rather than observed. Scaling ZIP ZORI by the local HUD bedroom ladder produces modelled monthly estimates of $1,653 for a studio, $1,951 for one bedroom, $2,338 for two bedrooms, $3,275 for three bedrooms, and $3,916 for four bedrooms. They are modelled estimates, never measured bedroom rents. The two-bedroom figure equals the overall ZIP index because the scaling uses that local ladder as its anchor. The $1,324 step from the one- to three-bedroom model, a 67.9% increase, reflects the ladder’s relative spacing. It compares only the model’s internal size pattern and cannot infer a listing’s condition, utilities, term, or availability.
Housing stock gives composition, not a count of suitable vacancies. The ACS ZCTA has 27,957 housing units, including 1,001 vacant units, for a 3.6% overall vacancy rate. Within the reported vacant inventory, 248 units are classified for rent and 388 for sale; seasonal and other vacancy categories are not interchangeable with a rental listing. The structure tabulation lists 25,381 single-family units and 586 units in its large-multifamily category. Those counts describe the ZCTA’s reported stock mix, but they do not establish the physical attributes, asking price, lease terms, or current availability of any unit. In particular, a vacancy classification cannot demonstrate that a specific home can be rented or will fit a household.
The wider comparisons establish direction but are only context. In the supplied context, Meridian city’s rent is $2,065, Ada County’s rent is $1,926, and the Boise City, ID metro’s rent is $1,874. Each named scope is broader context rather than a substitute for ZIP evidence, and the ZIP index is above all supplied figures. Meridian city’s renter share is 25.4% and Ada County’s renter share is 29.2%, both above the ZIP’s reported share. For vacancy, the ZIP rate lies between the Meridian city rate of 3.1% and Ada County rate of 4.2%. Different geography, housing mix, source timing, and series definitions limit any conclusion beyond these scoped comparisons.
Several limits frame a property-level use. This five-digit label is both the Zillow ZIP market identifier and the Census ZCTA match used here. A ZCTA is a statistical area and is not identical to a USPS delivery ZIP. Zillow’s current asking-rent index, ACS’s multiyear occupied-home survey, and HUD’s administrative bedroom standard use different populations, definitions, and dates; ACS estimates also carry sampling uncertainty. A property-level interpretation requires confirmation of the advertised base rent, rental type and bedroom count, included and separately billed utilities, lease duration, deposits and recurring fees, availability date, and the address’s applicable ZIP. These checks connect the aggregate evidence to listing terms without converting an index, a burden share, or a vacancy count into a fact about that property.
