    Overview

    This for-sale duplex is configured as a spacious 4BR property with more than 3,200 square feet of total space. The current setup includes long-term renters in place, with tenants paying below-market rent. The layout supports straightforward owner-occupant living while retaining the option to rent out a second unit.

    The property is located at 770 NE 91ST AVE in Portland, Oregon (97220). Prospective buyers should plan to coordinate with the listing for property access, as the current occupants are set to “Do Not Disturb”.

    For investors and owner-occupants, the appeal is the combination of established occupancy and the flexibility to live in one side while generating rental income from the other unit. Buyers seeking a duplex they can potentially manage with an owner’s presence may find the current long-term tenancy structure particularly relevant. Please note that any changes in occupancy, rent levels, or unit configuration would need to be confirmed directly with the seller, along with all applicable terms and conditions for the occupied property.
