Once it's finished, the Mansions at Acqualina will be a 79-unit building in Sunny Isles, Miami Beach with some pretty large price-tags. The units each have indoor pools, Italian glass tiled bathrooms, granite floors, and embossed crocodile leather closets. Even if the project won't be completed until 2015, units are available for pre-order now, with the penthouse being priced at $50 million, making it the most expensive residential listing in Florida. [Zillow]
