EcoFlats (3947–3951 N Williams Ave) is a premier mixed-use asset built for long-term value and stable cash flow. Located in Portland’s established North Williams corridor, the property features 18 apartment units over 3,657 square feet of commercial retail on an 11,800-square-foot EXD-zoned lot.
Unlike standard properties vulnerable to market spikes, EcoFlats was designed to protect the owner from the biggest threat to rental income: rising utility costs. Operating at 65% higher energy efficiency than traditional buildings, it features a 21-kW solar array and open-air common areas that eliminate shared HVAC overhead entirely.
The ground floor is 100% leased to stable local brands on NNN/CAM leases through mid-2028, securing a predictable revenue base. Additionally, a pre-stubbed rear footprint allows for 12 more units without expensive city hookup fees.
INVESTMENT HIGHLIGHTS
Lower Operating Costs & Higher Profit:
A 21-kW solar array, thermal trellis, and advanced water-heating system keep utility bills low. Open-air hallways eliminate heating and cooling costs for common areas, slashing monthly overhead and protecting your bottom line.
Reliable Commercial Income:
The ground floor is 100% leased through mid-2028 to stable local favorites, Migration Brewing and Bigtime Tattoo. Triple-net (NNN/CAM) leases ensure tenants cover expenses, providing steady cash flow independent of apartment market cycles.

Easy Room to Grow:
Zoning allows for 12 additional units on the rear 50x50 lot. Utility lines are already run to the site, allowing a buyer to skip expensive city hookup fees (SDCs) and plug straight into the existing solar and boiler systems.
