A new Marriott Autograph Collection hotel, which will be part of a larger mixed-use development on the site of the former West Palm Beach City Hall, got a $42 million boost from Aztec Group Inc.

Aztec managing director Boaz Ashbel in Miami secured the loan, which covers 70 percent of the $60 million construction cost, on behalf of hotel developer, owner and manager Concord Hospitality Enterprises Co. Florida Community Bank was the lender in the deal that closed May 15.
