Prime development opportunity in Seattle’s rapidly growing Mount Baker neighborhood. Positioned on a desirable corner lot, this LR2-zoned property offers exceptional flexibility for builders and investors—ideal for townhomes, small multifamily (2–4 units), or a larger-scale apartment or condo project (buyer to verify). The existing home is livable, with a long-term tenant recently vacated, but the true value lies in the land and its development potential. All utilities are available on-site, helping streamline the entitlement and building process. The flat, usable lot configuration further enhances efficiency for site planning and construction. Located just minutes from the Mount Baker light rail station, this property offers strong transit-oriented appeal, making it highly attractive for future residents and renters alike. Convenient access to I-90 provides quick connectivity to I-5, I-405, downtown Seattle, Bellevue, and beyond. This central location continues to see strong growth, driven by infrastructure, accessibility, and increasing housing demand. The seller has not pursued full development, creating an opportunity for the next owner to step in and unlock the site’s full potential. Seller is open to working with buyers exploring a mid-sized project. Opportunities like this—combining zoning flexibility, location, and upside—are increasingly rare in this high-demand corridor. Bring your vision and capitalize on the growth of Mount Baker.
