Proven Rental Demand in a Supply-Constrained Market
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, up from $1,595 at the start of 2024 — a 9.7% increase over roughly 18 months. 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 $3,400/month, supported by documented lease history and reliable month-to-month tenancy.
Live in One, Rent the Other — A Built-In House Hack
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.
St. Helens: Portland Metro Access Without Portland Metro Prices
Situated along the Columbia River in Columbia County, St. Helens sits approximately 30 miles northwest of Portland via Highway 30 — close enough for a reasonable commute, far enough for significantly lower cost of living. The city has seen consistent population and rental demand growth as buyers and renters priced out of the core metro seek affordable alternatives with genuine small-town character. For investors, that dynamic translates to a stable renter pool, low vacancy risk, and rent growth that has outpaced many larger markets on a percentage basis.
A Walkable, Self-Contained Community with Strong Local Infrastructure
St. Helens offers tenants a fully serviced lifestyle without dependence on Portland. A revitalized historic downtown, Columbia River waterfront, established school system (Lewis & Clark Elementary, St. Helens Middle and High), and proximity to major employers along the Highway 30 corridor all support long-term tenant retention. The subject property's location on Deer Island Road provides direct access to the city's core amenities while offering the privacy and parking of a residential neighborhood setting.
