2027 edition · Research reviewed November 7, 2026
Colliers is our #1 editorial office leasing firm for a Detroit owner seeking a current agency campaign grounded in a named assignment. Newmark, Friedman Real Estate, CBRE and Cooper Commercial Group are the four alternatives. We apply the nine firm criteria to landlord work and distinguish downtown, suburban and Flint evidence. A recognizable building supports a recommendation only when the source establishes who was appointed to market it.
How we rank commercial real estate brokerage firms in Detroit–Warren–Flint, MI
Our 2027 ranking uses the same nine-part methodology as our 2026 guides. We compare local specialists with regional and national firms using current public sources, verified service geography and relevant specialization in office leasing for landlords. We evaluate each candidate using these nine criteria:
- Experience and reputation
- Market knowledge and specialization
- Network and connections
- Technological capabilities
- Data transparency and accuracy
- Online presence and digital marketing
- Local and global reach
- Service range
- Innovation and customer focus
Using these criteria, we identify one #1 editorial recommendation for the assignment described below and compare other qualified options. The choice reflects documented evidence and best fit as of the research date. Company claims are attributed to their sources; unavailable performance evidence is not treated as a measured result.

Colliers — our #1 for a documented Detroit office agency brief
The February 2026 announcement for 600 Renaissance Center names John Fricke, Randall Book and Audrey Correa to lead leasing. Colliers: February 2026 leasing appointment at 600 Renaissance Center Colliers’s current Detroit agency page also describes marketing, research and prospect reporting. Colliers: Detroit office agency team and Gary Grochowski We select this combination of a dated appointment and stated campaign functions. Ask the proposed team what transfers to your property and what depends on the particular downtown tower. An appointment does not prove subsequent leasing results.
Newmark — office lease evaluation and owner advice
Canvasser’s current profile identifies both landlord and tenant representation involving office lease evaluation and negotiation. Newmark: Daniel Canvasser, office lease and build-to-suit advisory We include Newmark where an owner wants the lease structure examined alongside the marketing argument. Request a clear explanation of the property’s likely audience and the decisions that would change its competitive position. Discuss conflicts before sharing sensitive ownership priorities.
Friedman Real Estate — a local landlord platform
Todd Hawley’s current profile establishes a Metro Detroit landlord practice. Friedman: Todd Hawley, current Metro Detroit landlord practice Friedman’s February 2025 Ally Detroit Center announcement supplies a dated office example with the landlord side explicitly identified. Friedman: February 2025 Ally Detroit Center landlord representation We include the firm for a local agency comparison while preserving the date of that transaction. Ask for the current assigned team; a historic deal does not guarantee that identical personnel will lead a new engagement.
CBRE — office and flex agency scope
A.J. Rich’s current Southfield profile identifies office, flex and industrial leasing and lists agency leasing among his specialties. CBRE: A.J. Rich, office and flex agency leasing scope This supports comparing the practice where a property needs a positioning discussion across those uses. Require the campaign to distinguish verified capabilities from possible changes that still need investigation. A broader specialty should not turn a hypothetical use into a marketing fact.
Cooper Commercial Group — a Flint office comparison
The Genesee County property portal identifies Cooper as the contact for an office listing in Flint, updated in August 2026. Genesee County property portal: named Cooper office leasing contact, updated August 2026 Its own site confirms the Flint base. Cooper Commercial Group: Flint base and Genesee County practice We include this local alternative for owners whose property is in that part of the region. The listing is role and location evidence, not a statement that its availability or displayed financial terms remain current.
Require an owner decision process
A campaign should explain who the property can serve, which objections are expected and what ownership can change. Agree on prospect feedback and approval responsibilities. Colliers leads because a recent explicit agency appointment makes the role reviewable. The public sources do not establish a consistent comparison of achieved rents, concessions or lease-up speed. Those questions require property-level references and context, not an invented numerical score.
