Onsite Networks Testimonial

Onsite Networks testimonial I am writing in recognition of the quality service provided by Optimal Spaces Inc. and Stephen Sunderland in finding us a sublease at 41 Madison Avenue. We strongly recommend them for the excellent job they did. They were efficient and responsive in locating spaces that met our needs and corporate image, aggressive in negotiating on our behalf, and effective in communicating our needs to the landlord and getting our offer accepted. I look forward to working with the team at Optimal Spaces Inc. again. Very truly yours, Dennis Jules Kessler Chief Financial Officer On Site Networks, Inc

Why Optimal Spaces –

  • Save 15–20% on your business costs.
  • Save 100–200 hours of research.
  • Access to all available spaces.
  • Specialized real estate expertise.

Alone or with other broker

✕
  • Miss deals and hard-to-find spaces.
  • Potential conflict of interest (often represent landlords).
  • Only 10% of available spaces are online.

  • May not get the best terms or uncover hidden costs.
Why Use a Tenant Broker: Your Advocate in Commercial Real Estate
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
5. Time Savings & Process Management
6. Mitigating Risk (the “Gotchas”)
Summary: Don’t rely on the landlord’s agent. A tenant broker is your advocate, provides better data, negotiates a complete package, and typically costs you nothing.
