About Mar-Azul
Mar-Azul is a roughly 11-story condominium at 600 Grapetree Dr. Completed in 1974. MLS records most often show about 11 stories.
Key Biscayne is an island village reached by the Rickenbacker Causeway, with Crandon Park to the north and Bill Baggs Cape Florida State Park to the south. Because the building dates to 1974, review the association’s reserves, assessments and milestone-inspection status before you buy.
Building Fees & Assessments
MLS listings for Mar-Azul have shown a median association fee around $1.21/sqft/month -- shown per square foot, not as a flat dollar figure, since that's comparable across unit sizes rather than skewed by whichever units happen to be listed right now. This is a point-in-time reference, not a live figure, and can change over time. Confirm the current fee for a specific unit before making an offer.
Mar-Azul is 52+ years old, which puts it within Florida's Milestone Inspection requirement (SB 4-D, post-Surfside law covering condo/co-op buildings 3+ stories, coastal buildings inspected at 25 years and every 10 years after). Request the building's most recent milestone inspection report, structural integrity reserve study (SIRS), and reserve fund status before purchasing -- these determine whether a special assessment is likely.
Specific reserve fund balances, pending special assessments, and financial statements aren't public MLS data -- request them directly from the condo association or your agent before making an offer.
Rental Potential
See the live "Monthly rental from" figure above for Mar-Azul's current lowest asking rent, and the market snapshot's closed-lease count and median rent for actual rental demand over the trailing 12 months -- both update automatically, unlike a number written here. Specific rental rules -- minimum lease term, rentals allowed per year, and whether short-term/Airbnb-style rentals are permitted -- are set by the condo association and vary by building. Verify current rental restrictions directly with the association before buying as an investment.
