Double Agent Testimonial

Double Agent testimonial To Whom it May Concern: This is to give reference for Stephen Sunderland, who provided commercial real estate brokerage services to our firm, Double Agent. His work led to our signing of a five year lease and five year optional extension on 6,200 square feet of SOHO office space at a very competitive rate. I was extremely impressed by Stephen's professionalism and follow-through in helping us not only locate this space but also in bringing it to closing. He showed a good knowledge of our needs and through that avoided wasting our time showing us unsuitable properties. I would be glad to provide further reference for Stephen and you may feel free to call me about him. I can give him an unqualified recommendation. Best regards, Andrew Szabo Chairman and CEO Double Agent, Inc.

1. The Crucial Distinction: Whose Side Are They On?
2. It Almost Always Costs You Nothing
3. Access to “Hidden” Inventory
4. Negotiating Beyond Base Rent
