## Description

### Agent Description
This well-maintained commercial property is positioned on a desirable corner lot with traffic count of 11,400 and ample parking. The 840 sq ft main level is complemented by a full, unfinished basement-offering valuable storage or expansion potential. The site features 10+ parking spaces plus a detached one-car garage for added flexibility. Extensive recent improvements enhance both functionality and long-term durability, including updated insulation, drywall, windows, doors, flooring, plumbing, ductwork, siding, and a metal roof. Additional exterior upgrades include new concrete along the west side of the building and foundation reinforcement on the west wall in the basement. An ideal opportunity for investors, owner-operators, or small business users seeking versatile property with strong structural updates already in place. Prime corner-lot exposure, abundant parking, and major system upgrades make this a standout offering.
