ZIP 83634 begins with a rent-versus-resale tension, but the rent record itself remains positive. Zillow’s June ZORI is $2,239, 3.63% above the same month a year earlier. Exact same-month annualized changes are that same rate over one year, 3.24% over three years, and 4.01% over five years. The current direction therefore confirms the longer positive path rather than breaking from it, although it is slower than the longest-horizon pace. Annualized monthly-return variability is 2.71% and the maximum drawdown is -3.20%. The historical series has complete coverage. Its transparent national discovery ranks among history-eligible ZIPs are 803 for momentum, 1,071 for stability, and 576 for the balanced measure. These are backward-looking measurements, not forecasts or investment recommendations; variability and prior drawdown mean a single current index reading deserves measured, rather than absolute, confidence.
Source boundaries explain why no single rent number can stand for every use. Zillow ZORI is a typical observed ZIP asking-rent index blended across rental types, not a lease-level quote. The matched Census ZCTA’s ACS 2024 five-year survey instead reports $1,690 median gross rent among occupied renter homes and includes selected utilities. 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. The ACS figure is 32.5% below the asking index, a period, sample, and concept difference rather than an appraisal. HUD’s FY2026 local two-bedroom FMR is $1,655, 35.3% below ZORI. HUD FMR is an administrative bedroom-specific standard, not asking rent.
The bedroom display is a sizing model, not a set of observed rental comps. Scaling the current ZIP ZORI through the local HUD ladder produces modelled monthly estimates of $1,583 for a studio, $1,868 for one bedroom, $2,239 for two bedrooms, $3,136 for three bedrooms, and $3,750 for four bedrooms. These are modelled estimates, never measured bedroom rents: the calculation preserves local HUD bedroom relationships while anchoring their level to the blended Zillow index. A reader comparing a listed unit should treat the relevant model output only as a consistency screen and separately verify the actual layout, included utilities, and asking terms. The estimates do not imply that any particular bedroom type is available at that figure.
Affordability signals point in two directions and need their own ACS framing. The matched ZCTA’s ACS median household-income estimate is $97,171, with a reported sampling margin of error, while a 30% required-income screen for the current ZORI is $89,560. Annualizing the asking index against that income produces a 27.65% asking-rent-to-income ratio. This 30% screen is arithmetic, not advice and not an applicant qualification rule; it also compares area-wide median household income with a ZIP asking-rent index. In the ACS occupied-renter universe, 23.9% of renter households reported gross-rent burden at or above the screen. The burden measure is survey evidence about households, not proof that a particular current unit will be affordable.
The ACS ZCTA stock counts add a supply context but not a unit-availability finding. Of 10,849 housing units, 10,034 are single-family units. It records 314 vacant units, a 2.89% vacancy rate, alongside a 16.7% renter share and 137 units classified vacant for rent. These classifications describe the survey’s area-wide housing inventory, not live listings or the condition, price, lease date, or location of a specific home. Vacancy also includes categories beyond units for rent, so neither the total vacancy rate nor the vacant-for-rent count establishes that a renter can secure a particular unit. The concentration of single-family stock is a census structure classification, not a statement about rental suitability.
Wider comparisons place the ZIP reading in perspective without replacing it. In the City of Kuna context, rent is about $2,236; in Ada County context, rent is $1,926; and in the Boise City, ID metro context, rent is $1,874. Each is a named wider-geography context value, not a ZIP observation, and each is distinct from the matched ZCTA’s ACS median gross rent and from HUD’s administrative standard. The ZIP asking index is nearly aligned with the city-context reading and sits above the county and metro context readings. That comparison describes level differences across supplied geographies and source scopes; it cannot identify a cause, a neighborhood pattern, or a likely next move.
Redfin gives the direct ZIP for-sale side of the tension. In its direct rolling-three-month ZIP resale observation, the median sold price is $464,890, down 2.13% year over year, with 383 homes sold and a median 56 days on market. Redfin reports 239 homes of inventory and 1.9 months of supply; the average sale-to-list ratio is 99.74%, a for-sale transaction signal. This is resale evidence, not rental transactions, rental comps, or property operating economics. The decline in the resale median challenges any simple reading that the rising asking-rent index alone represents uniformly strengthening conditions. At the same time, sales volume, marketing time, inventory, supply, and sale-to-list evidence describe resale liquidity only; they neither confirm a unit’s rent nor alter the ACS burden screen.
Finally, annualized ZIP ZORI divided by the Redfin median sold price is a 5.78% cross-source screening ratio only. It is not a cap rate, net return, expected return, or property yield, and it cannot supply a unit-level rent, expense profile, or resale valuation. The record also has survey error in ACS estimates, a blended rental-type index in ZORI, an administrative HUD benchmark, and a rolling resale window; none is a substitute for an address-specific record. Before drawing a property-level conclusion, check the live asking rent and concessions, actual bedroom count and unit condition, included utilities, lease terms and availability date, and, for a sale, list history, transaction condition, taxes, insurance, and association charges. Which of those address-level facts materially changes the screen?
