Caldwell has grown faster than Nampa in percentage terms over the last 36 months. The downtown revitalization, Indian Creek daylighting, and College of Idaho anchor have changed the narrative materially. Ownership turnover is accelerating. Our investor flow captures pre-listing opportunities from aging owners.
Flips
Flip entry basis
$220K–$290K
Typical
Flip ARV range
$310K–$390K
Typical
Caldwell flip product is the most value-oriented in the Valley. Rehab scope creep is the main risk: older stock often has foundation, sewer lateral, or service-panel work that under-scope'd estimates miss.
SFH Rentals
3BR SFH average
$1,450–$1,750
Monthly · by neighborhood
Caldwell SFH rentals trade at the highest rent-to-price ratios in the Treasure Valley for entry-level product. Vacancy is competitive with Nampa.
Multifamily
2–4 unit cap
6.5–7.5%
Stabilized
Caldwell 2–4 unit product clears 6.5–7.5% cap on stabilized deals. The 5–20 unit window attracts less institutional attention than Nampa or Meridian. Direct owner contact is typically the path.
Infill & Development
Caldwell's infill pipeline is materially underbuilt relative to growth. We track parcels within the revitalized downtown corridor where small-format retail plus residential is viable.
Land & Development
Caldwell has the most active ag-to-residential conversion discussion in Canyon County. Water rights and irrigation district status are the top two diligence lines.
Lot Splits, ADUs & Duplexes
Caldwell's Article 12 (2025 update) allows ADUs up to 900 square feet or two bedrooms. The owner-occupancy requirement was removed in the 2025 amendment.
Split-zoned parcels under §10-01-08(E) require a separate zone finding, which typically adds 30 to 60 days to permitting timelines. Parcel-by-parcel diligence is the work.
