Executive Summary

Northmarq is pleased to present the offering for Brookside Commons in Issaquah, WA. This is a ±6,647 square foot office property that presents a unique opportunity for investors, owner users, or a full-building tenant to secure a well-located asset in one of East King County’s most desirable suburban office markets. The property is currently occupied by more than 20 private office tenants on month-to-month leases, providing immediate income while allowing a new owner to gradually mark rents to market and secure longer-term tenancy. Alternatively, the flexible lease structure allows for the potential conversion to a full-building occupancy by an owner-user or single tenant over time. The property benefits from 25 designated covered parking stalls. This parking ratio exceeds most comparable office properties in the submarket, providing a valuable amenity for tenants, employees, and visitors.
Ownership is offering the property for sale or for lease to a single tenant, creating multiple pathways for a buyer or occupant to capitalize on the asset’s flexibility. Investors can continue the current multi-tenant office model and capture upside through incremental rent increases and longer lease terms, while owner users or full-building tenants have the rare opportunity to establish a presence in a highly supply-constrained submarket. The Issaquah office market continues to experience limited new development and strong demand from professional service firms and local businesses, supporting rental rates approaching $40/SF for quality office space and positioning the property well for future income growth.
