Essex River Ventures has appointed Boston-based NAI Hunneman as the exclusive leasing agent for a three-building, 309,000-square-foot, mixed-use commercial portfolio in Wilmington.

"NAI Hunneman’s leasing team has done a great job in successfully leasing spaces in our other buildings," said John Fenton, president of Boston-based Essex River Ventures, a real estate investment firm serving institutional and high-net-worth investors. "We are excited to have NAI Hunneman on board to lease our Wilmington portfolio."

Senior Vice President David Gilkie, Senior Vice President James Boudrot, and Senior Associate Michael McCarthy, all of NAI Hunneman, will lead the leasing efforts for the three-building portfolio, totaling 309,000 square feet:

The buildings include 299 Ballardvale St., a single-story, 75,000-square-foot flex/office building, which is currently fully leased; 300 Ballardvale St., a two-story, 114,000-square-foot office building, with several smaller suites from 2,000 to 7,000 square feet available for lease; and 301 Ballardvale St., a single-story, 120,000-square-foot flex/office building, which has 57,000 square feet currently available for lease.

"We’re looking forward to working with Essex River Ventures’ management team, as well as the potential tenants who wish to take advantage of the cost-saving, low-rent opportunities Essex River Ventures is offering at these beautifully maintained buildings," said Gilkie.
