Are there any investment sales brokerage firms that focus on institutional deals for office properties?

Yes. Several investment sales brokerages specialize in institutional office-property transactions—typically large, core/core-plus, value-add, or distressed assets sold to REITs, private equity, pension funds, insurance companies, and other institutional buyers.

A few well-known firms with strong institutional office platforms include:

• CBRE Capital Markets
• JLL Capital Markets
• Cushman & Wakefield Capital Markets
• Newmark
• Eastdil Secured
  • Often considered especially strong in large, institutional, trophy, and complex deals
• Colliers
• Walker & Dunlop
  • More multifamily-heavy overall, but active in some institutional commercial transactions
• CBRE Investment Properties / HFF legacy teams
• Cushman & Wakefield institutional office teams in major markets
• Savills
  • Particularly in office-heavy gateway markets
• Berkadia
  • More multifamily-centric, but has commercial/institutional capabilities in select markets

There are also boutique firms and market-specific teams that focus heavily on office investment sales in major metros like New York, Washington, D.C., Boston, Chicago, Los Angeles, San Francisco, and Dallas. Many of the most effective institutional office brokers are not the firm name alone, but specific teams or individuals with deep owner/investor relationships.

If you want, I can also give you:
