VSA Consulting Group Testimonial

VSA Consulting Group testimonial To whom it may concern: I am writing to recommend Stephen Sunderland and Optimal Spaces Inc. for the excellent job they did in finding us a lease at our new space. They were fast and effecient 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, Jack Sichterman Partner/Managing Director

Why Optimal Spaces –
Tenant Broker

  • No fee for clients renting space.
  • We work for YOU, not the landlord.
  • 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.
  • Lack of specialized expertise.
  • 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”)
