Overview

The offering consists of two adjoining properties at 522–526 Washington Avenue, Portland, available individually or as a package. The combined portfolio includes a renovated commercial office building and a mixed-use two-family with commercial space. The property configuration supports mixed uses within one acquisition, with separate components that can be operated or leased in a coordinated way.

Located along Portland’s Washington Avenue corridor, the properties benefit from high visibility. The remarks also note convenient access to I-295, Back Cove, and the Roux Institute campus. A combined parking footprint is available across the parcels, supporting day-to-day customer and tenant access.

This package is suited to investors seeking multiple streams through office and mixed-use components, or to owner-users who want to occupy one portion while leasing the other. The ability to acquire both parcels together or separately adds flexibility for underwriting and operations, while the existing improvements provide a ready foundation for continued leasing and use.
