The Collier Community Foundation Collier Housing Impact Investment Fund made its first loan of nearly $1.3 million to cover impact fees, enabling the opening of Ekos Allegro, a development for fixed-income seniors 62 and older. The fund incentivizes the development of affordable units. The loan made to the complex developer McDowell Housing Partners was facilitated by the CCF-funded Housing Alliance Inc. Residents started moving into their new homes this week at the senior living facility on Rattlesnake Hammock Road, just east of Collier Boulevard. Without this loan, the opening would have been delayed at least another four or five months, CCF officials said.
