Why Optimal Spaces Tenant Broker

  • Lease negotiation: full terms, renewals, expansion options
  • Cost analysis, inventory identification, negotiating scope
  • Risk mitigation against hidden pitfalls

Cost Savings

  • Negotiate 30+ leasing points to prevent hidden costs
  • Save 10–15% on total leasing costs
  • Save 100–200 hours filtering unviable spaces
  • Property access via broker databases and networks (off-market, subleases, future availability)

Alone or With Other Brokers

  • Inherent conflict of interest as most brokers represent landlords
  • Risk of weaker terms and overlooked hidden costs
  • Heavy workload falls on you while best spaces are missed

Nuverse Advisor LLC Testimonial

Nuverse Advisor LLC testimonial Dear Stephen, We would like to thank you for your assistance in helping us to arrange a sublet in Olympic Tower. My partners and I were determined to sublet a space that was fully furnished and equipped to our specifications at a fair market value. We utilized several different brokers, but we found that only you consistently found new sublet opportunities for us during the entire year of our search. When we began our search, prices for Class A office space in the Plaza District ranged from $80-150/RSF, by the end of our search the prices had fallen to $50-$85/RSF. Your hard work and tenacity at finding new listings allowed us to find the ideal space at the right price in Class A. Thanks for sticking with us. Sincerely, Elias Saal
