A large former Comerica Inc. office building in Auburn Hills is heading to auction next month.

Bidding for the Dallas-based bank’s owned Oaktec Office Centre building at 3551 Hamlin Road — which it vacated as part of a multi-building consolidation — starts Sept. 23 with opening offers starting at $800,000, according to the auction’s website on Ten-X.com.

Built in 1987, it sits on close to 13 acres across two separate parcels and has nearly 210,000 square feet.

On Tuesday, a Comerica spokesperson said the bank didn’t have “anything to add other than the details posted on the (auction) website.”

Comerica, which was headquartered in Detroit until 2007, has been unloading some of its office buildings as part of its consolidation into a new 340,000-square-foot property dubbed the Comerica Great Lakes Campus, which officially opened on Tuesday.

Some 2,100 employees work out of the new campus, which spans two buildings that are connected by a 21,000-square-foot addition in the middle.

Since Comerica announced its consolidation in September 2022, it has sold off two of the three buildings it was vacating during the process.

A 382,000-square-foot building at 39200 Six Mile Road sold to Birmingham-based Markus Management Group for $21.1 million in September 2023, and in July 2023, Michigan United Credit Union paid $3.9 million for the old 31,000-square-foot Comerica building at 3501 Hamlin Road. 

Markus Management Group is planning a mixed-use redevelopment of its new Livonia property, while MUCU bought the old Comerica building for a new branch and headquarters.

Comerica still has what it calls its Auburn Hills Operations Center, located at 3701 Hamlin Road, which is about 371,000 square feet, and is being retained. The bank has employees in technology, cybersecurity, corporate real estate, procurement and marketing in that building.

According to CoStar Group Inc., a Washington, D.C.-based real estate information service, other Auburn Hills office buildings that have sold in recent years include: 

• The 120,000-square-foot Auburn Hills Corporate Center at 900 N. Squirrel Road, which sold in December 2022 for about $7.16 million, or $59.65 per square foot
• The 192,300-square-foot building at 2020 Taylor Rd., which also sold in December 2022 for $24.625 million, or $128.05 per square foot
• The 137,600-square-foot building at 3250-3256 University, selling in June 2023 for about $7.9 million, or $57.39 per square foot

Not that long ago, online auctions were pretty much reserved for distressed properties, although that has changed over the years and platforms like Ten-X, RealINSIGHT Marketplace and Crexi are all competing with each other to host auctions.
