Executive Summary

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 just rented at $1,600/mo. Both units are all-electric with public water and sewer (billed-back), 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.
