74 William St. W., Waterloo — A dual-opportunity property in one of Waterloo's most sought-after residential neighbourhoods — collect rental income today while holding a prime redevelopment asset for tomorrow. This legal non-conforming fourplex offers a compelling unit mix: two spacious 3-bedroom suites and two generous 5-bedroom suites, ideal for student, professional, or family tenants alike. Ample on-site parking adds further appeal for renters. The location is exceptional — a short 5-minute walk to the shops, restaurants, and vibrant nightlife of Uptown Waterloo. This property carries significant upside: a developer or investor could explore rebuilding or intensifying the site to maximize density in an already-proven location. Whether you hold, renovate, or redevelop, 74 William St. W. is a strategic addition to any portfolio.
