Kuna is southwest Ada County. Lower basis than Meridian, faster growth than Eagle, and the most active annexation conversation in Ada County. Our investor network has focused here for three years on annexation-and-build plays.
Flips
Flip ARV range
$380K–$480K
Typical
Kuna flip product is thinner than Meridian's but increasing with turnover. Rehab budgets pencil tighter than Meridian.
SFH Rentals
Kuna SFH rentals run at Meridian's basis with slightly softer rent. Tenant quality is stable and vacancy is competitive.
Buildable Infill
Kuna's buildable infill is the play. Mid-block corner lots, alley-accessed parcels, and lots adjacent to utility stubs are where our investor pipeline concentrates. Entitlement clocks are faster than Meridian's.
Lot Splits, ADUs & Duplexes
Kuna adopted Ordinance 2026-05A on April 7, 2026, removing the owner-occupancy requirement and waiving parking within 1,500 feet of a transit stop. Maximum ADU size: 900 square feet or 50% of primary.
The city's updated Future Land Use Map (March 2025) added Medium Density Residential and Mixed-Use designations in northeast and northwest growth corridors, expanding the infill envelope considerably. We track lot geometry against setbacks to pre-qualify viable parcels before underwriting.
Annexation & Development Land
Annexation window basis
12-to-24-month horizons typically clear at 50–65% of post-annexation comparable.
Kuna's annexation pipeline is the most active in Ada County in percentage-of-city-limits terms. We've represented acquisitions in the 12-to-24-month-to-annexation window where basis clears at 50–65% of post-annexation comparable.

Renew take
Kuna's growth is annexation-driven — the 2023 FLUM expansion is what's pulling the curve up. The land thesis here is timing: catch parcels in the 12-24 month pre-annexation window where basis runs 50-65% of post-annexation comparable.
Kuna's annexation pipeline — track the City Council pre-annexation queue; the FLUM gates the 2027-28 land repricing.

Renew take
Kuna sits in the entry-tier Ada County band — the lowest-basis flip and rental product in the county. New-build supply pulls the median up but the resale 1990s-stock cohort is the investor target.
New-build absorption — when D.R. Horton/Lennar inventory days cross 90, resale comps flatten and the flip math compresses.
