"That shows how much people love the building," says Lincoln Property Co. broker Jeff Moore, who joined Boston office chief John Miller in negotiating the latest leases on behalf of Invesco. "It's a class B building with class A amenities and location," Moore tells GlobeSt.com of the building, an historic treasure revered as one of Boston's first commercial properties. Lincoln has represented 84 State St. since Invesco acquired the asset approximately 10 years ago, and Moore says the fundamentals have remained superior on both occupancy and rent levels.

The home to such well-known firms as Colliers International, 84 State St. completed nearly 15,000 sf of transactions in the recent flurry to reach full occupancy. The largest deal was cemented by Brooke Private Equity Advisors, followed by Gelb & Gelb, Mad River Management and Abbott Real Estate Development. Tenant brokers included Andy McDonald for Mad River, and Chris Rogers and Bryan Sparkes of Grubb & Ellis assisting Gelb & Gelb. Brooke was represented by Andy Hoar and Taidgh McClory of CB Richard Ellis.

Specifics of the individual leases were not provided, but Moore did acknowledge rents have been exceeding $40 per sf at 84 State St. in many latter-day deals. Fit out allowances were said to be limited, and concessions such as free rent that were commonplace in Boston barely a year ago were reportedly non-existent. That should prevent the returns from becoming diluted.
