Oceanfront condominiums line the Atlantic side of Key Biscayne from Crandon Park south along Crandon Boulevard, Ocean Lane Drive and Ocean Drive. The older generation includes the Commodore Club, from the early seventies, and Key Colony's Tidemark building, along with Casa del Mar, Mar Azul and the Towers of Key Biscayne. Oceana Key Biscayne on Ocean Drive is among the newer luxury addresses on this stretch. Salt air and sand take a toll on concrete, so the documents deserve as much attention as the view: ask for the milestone inspection, the structural integrity reserve study, the funded reserves, any special assessment and the pet and leasing rules. Two units on the same floor can cost very different amounts to own once the association's finances are read.
