Nampa · Canyon County
Where the cash-flow math still works.
The largest Canyon County submarket. Lower basis, higher cap rates, and a resilient rental base. Flip product still pencils for the 2025 market.

Redfin
Nampa is Canyon County's anchor. More working-class than Ada County, with rent-to-price ratios that routinely beat Boise by 80–120 basis points. Our SFH rental and small-multifamily flow concentrates here.

Typical
Nampa flip entry-levels run $280K–$340K with ARVs $360K–$440K. Rehab budgets pencil tighter than Boise because buyer tolerance for finish is lower, but margins hold when the basis is right. Distressed inventory flows from absentee owners more than pre-foreclosure.

Nampa
Nampa SFH rentals are the highest-cap-rate SFH product in the Treasure Valley at scale. 3BR averages run at roughly $2,000 per month as of Q1 2026, and cap rates clear 6.5–7.5% on stabilized product.

B/C class
Nampa 2–4 unit caps run 6.0–7.0% on stabilized product. 5-to-20-unit runs 5.5–6.5% B/C. There's less institutional competition than Ada County, which means individual investors still win direct acquisitions here.
Infill & Development
Nampa's infill pipeline is underbuilt relative to Canyon County's growth. We track parcels where 2–4 unit construction pencils under current construction costs.
Land & Development
Canyon County has more buildable land inventory than Ada. Water rights and ag-to-residential conversions are a recurring conversation. We partner with local counsel on water-right transfer diligence.
Lot Splits, ADUs & Duplexes
Nampa's current ordinance caps ADUs at 500 square feet with owner-occupancy required. Idaho SB 1354, effective July 1, 2026, supersedes these restrictions, requiring Nampa to permit at least one ADU per lot without owner-occupancy requirements or square footage caps. Verify revised standards with Nampa Planning before applications.
Lot-split application fee: $150. A licensed PLS-stamped surveyor is required.
