The upper tier of the Key Biscayne condo market belongs to a short list of addresses. Oceana Key Biscayne on Ocean Drive and the Grand Bay buildings beside the Ritz-Carlton Key Biscayne are the newer luxury buildings, and the Ocean Club's towers, Ocean Tower One and Club Tower Two among them, supply large residences, two-level lanai homes and penthouses with ocean and bay views. Buyers at this level compare floor, exposure and layout across buildings, and many weigh a large island residence against a house on the canals. Before you offer, compare what the monthly fee pays for and the reserves behind it, and ask about the pet and leasing rules, since some Key Biscayne owners plan to lease the residence while they are away.
