Executive Summary

Colliers, as exclusive advisor, is pleased to present the opportunity to acquire the fee simple interest in 2101-2121 4th Avenue, also known as Fourth & Blanchard, in downtown Seattle, Washington (the “Property”).
Totaling 410,114 rentable square feet and currently 51% leased to 50 tenants, Fourth & Blanchard is one of downtown Seattle’s iconic office towers. With an average suite size of 4,281 square feet, the Property is extremely well positioned to target the majority of the tenant base in downtown Seattle. Between January 2022 and April 2026, 86% of the
new office leases signed in downtown Seattle have been for 10,000 square feet or less. With a new reset basis, Fourth & Blanchard is well positioned to capitalize on these smaller, budget conscious office tenants looking for a landlord to handle construction management on their behalf.
Fourth & Blanchard represents a rare opportunity to acquire a high-quality office asset in the heart of downtown Seattle, one of the West Coast’s most dynamic and supply-constrained urban markets. Strategically located at the intersection of Fourth Avenue and Blanchard Street, the Property benefits from premier accessibility, immediate proximity to Seattle’s core employment base, and walkable access to the city’s most desirable retail, hospitality, and residential amenities.
The offering presents a compelling basis opportunity, allowing investors to acquire a high-quality asset at a significant discount to historical sales and to replacement cost. Through a combination of targeted capital improvements and leasing execution, an investor can capitalize on the current tenant demand and further elevate the Property’s market position.
