Do two methods point the same way?

Zillow estimates a current home value. FHFA tracks repeat mortgage transactions. Their growth rates should be read side by side, not averaged.

Resident income

How local income has compounded

BEA per-capita personal income divides all personal income by the county population. It is broader than wages, but it is not household income or a measure of what renters can afford.

Renter affordability

Who carries the heaviest rent burden

HUD CHAS separates renter households by income relative to local HAMFI. Moderate burden means housing costs above 30% through 50% of income; severe burden means more than 50%.

County brief

What the local evidence says

01Decision frame

Ada County has a cash-flow-versus-entry-price tension. Zillow's 2026-06 median home value is $530,977, up 0.43%, against median asking rent of $1,926 and a 4.35% gross yield before costs. FHFA's 2025 repeat-transaction HPI rose 2.71%; its separate cumulative five-year measure uses a different vintage and method, so it must not be averaged with Zillow. Cash-flow-focused buyers should be cautious, while investors willing to investigate low pre-cost yield have a possible demand case, not a completed underwriting case.

02Housing economics

That yield must be tested against costs. HUD's two-bedroom FMR is $1,655, a payment standard rather than market rent; the supplied rent-to-FMR ratio is 116.40%, not an asking-rent estimate. Effective property tax is 0.52%, with median annual tax of $2,655. The combination indicates gross income with limited room for vacancy, maintenance, insurance, management and financing costs. Net yield and DSCR cannot be computed because operating expenses and debt terms are not published.

03Demand & competition

Demand evidence is mixed but worth checking. QCEW's covered-worker record shows an average weekly wage of $1,417; it describes jobs located in Ada County, not resident employment or unemployment. Tax-return migration produced net inflow of 2,463, while incoming movers' average AGI exceeded that of outgoing movers by $8,793—supportive context, not proof of tenant demand. Realtor.com's 2026-06 MLS evidence shows active supply declined and 16.12% of listings had price reductions; these are visible-supply and seller-concession measures, not closed-sale prices or buyer demand. Investor purchases were 598 of 7,599 total purchases, or 7.87%, showing non-occupant participation without measuring this property's competition.

04Risk & next checks

Risk limits the thesis. The modeled annual building-value loss ratio is 0.11%, and inland flood is the dominant hazard; the ratio is not an insurance quote or parcel-specific exposure. Before underwriting, obtain flood-zone and drainage data, insurance premiums and deductibles, condition and capital needs, vacancy and operating expenses, financing terms, and closed-sale and lease comparables. Without them, the record cannot establish net yield, DSCR, flood-adjusted carrying cost, or durable rents. It also does not make Ada County representative of Boise City.

WHAT THE LOCAL DISTRIBUTION SAYS

In the selected direct-evidence matches, Zillow ZORI—the typical observed asking-rent index—ran from $1,565 to $2,426 in June 2026: an $861 spread with a $1,891.50 median. Ada County’s Zillow index was $1,926, inside that span. This is a meaningful dispersion for a renter or housing provider deciding whether a specific listing fits a budget; it argues for testing the unit’s own ask rather than assuming one county price. Annual ZORI movement ranged from 3.4% to 8.6%, versus 5.2% countywide. Those changes describe trailing index movement, not a forecast or a guaranteed renewal outcome.

The three rent references answer different questions and should not be combined. HUD’s FY2026 two-bedroom FMR is $1,655 for the shown entries, a bedroom-specific administrative standard rather than an observed asking rent. The selected ZORI-to-HUD relationship spans 94.6% to 146.6%, a useful screen for identifying where the two benchmarks differ but not a prediction of what a unit will lease for. Separately, ACS 2024 five-year ZCTA median gross rent ranges from $1,232 to $2,065, while the county estimate is $1,577. That survey measure has a different time frame and geography from both Zillow’s current index and HUD’s standard.

Burden and vacancy do not form a simple trade-off in these ACS five-year ZCTA estimates. The reported renter burden share ranges from 35.5% to 57.8%, and vacancy from 2.2% to 8.2%. ZIP 83713 pairs the upper burden end with the lower vacancy end, an observation that does not establish why the measures coincide. The packet’s annual income screen at a 30% rent share runs from $62,600 to $97,040 for the current index, versus median household income estimates of $64,731 to $128,822. These are area-level survey and index comparisons—not renter-only household budgets or unit-level availability—so use them to bound a search, then verify the applicant’s income and the actual lease payment.

Coverage and geography limit the reading. The selection contains 12 of 14 eligible direct-ZORI ZIP/ZCTA matches and 54,674 renter households; it is not an exhaustive county or property inventory. Census ZCTAs are statistical areas, not USPS delivery ZIPs. Because ZIPs can cross county lines, display assignment uses the county with the largest HUD residential-address share; that share is as low as 84.5% for ZIP 83716. Before acting on a listing, verify its exact address and county location, bedroom count, advertised rent, availability date, utilities and recurring fees, deposits, lease term, and income or occupancy rules. Keep the unit quote separate from Zillow’s index, the ACS survey estimate, and HUD’s two-bedroom standard.

READ BEFORE USING

Census ZCTA estimates are ACS 2024 five-year survey results and ZCTAs are not USPS delivery ZIPs. They describe statistical geographies and survey concepts, so they should not be read as current unit rents, exact delivery-ZIP boundaries, or property-level conditions.

ZIP display assignment follows the largest HUD residential-address county share, yet ZIPs may cross county lines and the selected direct-evidence set is not exhaustive. Zillow ZORI, HUD two-bedroom FMR, and ACS median gross rent differ in timing, geography, and definitions; none substitutes for a live listing quote.

What can break the county thesis

  1. Low gross yield and unreported operating or financing costs could leave inadequate net cash flow
  2. Inland-flood exposure could produce insurance, deductible, drainage or property-specific costs not captured by the modeled loss ratio
  3. MLS and county-level indicators do not establish closed-sale pricing, occupancy, lease durability or property-level competition
Underwriting questions

Before pricing a property

What rent should I use in the initial screen?

Use the published median asking rent as market-rent evidence, while keeping HUD FMR separate as a payment standard rather than a market-rent estimate.

Can I calculate net yield or DSCR from this record?

No. The record provides gross yield before costs but does not publish operating expenses, vacancy, financing terms or debt service.

What should I verify about flood exposure?

Verify the parcel's flood zone and drainage conditions, then obtain property-specific insurance premiums and deductibles; the record identifies inland flood as dominant but provides no insurance quote.
