Deer Island Duplex
Multifamily | 6.29% CAP | 2 Units
Marketing description
Two homes, one lot — and one of the best entry-point investments in Columbia County. This St. Helens duplex offers a 2BR/1BA front unit (832 SF) currently leased through September 2026 at $1,750/month, plus a 2BR/1BA rear unit (720 SF) with its own private access from N 10th Street — vacant and ready for an owner-occupant or immediate re-lease at market rate. Combined rents at stabilization top $3,500/month. Both units are all-electric with public water and sewer, and the property has a track record of strong occupancy and consistent rent growth. Whether you're a first-time investor looking to house-hack, or a portfolio buyer adding proven cash flow in a Portland-adjacent market, this one checks the boxes. Conveniently located off Hwy 30, 30 minutes from Portland.
Investment highlights
- Both units at 1070 Deer Island Road have maintained consistent occupancy and steady rent growth since acquisition. Unit A has been continuously tenanted and currently collects $1,750/month. Unit B carried a $1,650 rent through mid-2025 before turning over, reflecting strong market-rate demand for affordable two-bedroom product in Columbia County. Combined gross rents at stabilization exceed $3,500/month, supported by documented lease history and reliable month-to-month tenancy.
- With Unit B currently vacant, an owner-occupant buyer has a rare, no-displacement path to entry. Move into the larger 832 SF front unit or the 720 SF rear unit accessible from N 10th Street, and immediately offset carrying costs with the income from the occupied side. At $1,750/month from Unit A alone, an owner-occupant can significantly reduce their effective mortgage payment from day one — making this a compelling alternative to a traditional single-family purchase with zero rental upside.
