Best Of Business for Commercial Property Management

Diamond Properties has earned a reputation for finding viable commercial properties and incisively pinpointing areas where they can be improved, which it then executes through a combination of capital improvement, market repositioning, and hands-on property management. The results of this vision and quality-driven customer service are consistently high tenant satisfaction and lease renewal rates. Throw in behind-the-scenes attributes like computer-controlled climate systems, modern elevators, advanced telecommunications, life-safety and card-access security systems, along with a robust commitment to solar energy production, and it’s easy to see why Diamond is a back-to-back winner in this category. - Westchester Magazine
