A sprawling mixed-use development in Palm Beach County got an $18 million boost with help from a Miami-based real estate real estate investor and merchant bank.

The 200-acre Tuttle Royale is to rise in Royal Palm Beach, and Aztec Group Inc. secured the refinancing for a 39-acre retail segment.

Aztec senior managing director Howard Taft and executive vice president Charles Penan arranged the loan on behalf of developer Tuttle Land Development based in Hillsboro Beach.
