How much does a home in Key Biscayne cost?

Key Biscayne sits near the top of the Miami market, but the range is wide. Apartments in the older buildings on Sunrise Drive and Galen Drive are the most attainable way in, oceanfront condos in Key Colony, the Commodore Club and the Ocean Club sit in the middle, and single-family homes, canal estates and the newest oceanfront residences carry the highest prices. The market table on this page shows the current median list and sold prices for single-family homes and condos, updated daily from the MLS.

Is Key Biscayne part of the City of Miami?

No. The Village of Key Biscayne has been its own municipality since 1991, with its own council, police, fire rescue and building permits, in Miami-Dade County and the 33149 ZIP code. Crandon Park at the north end is a county park and Bill Baggs Cape Florida State Park at the south end is a state park, so neither is part of the village. Check the municipality on the property tax record before you compare prices.

Can I buy a waterfront home with a dock in Key Biscayne?

Yes, though single-family waterfront homes are a small share of the island. Homes on the canals of the Cape Florida sections, on Mashta Island and on other bay and canal lots can have docks, and boats reach Biscayne Bay directly and the Atlantic beyond it. The oceanfront buildings face the beach instead. Dock permits, water depth, the seawall and the flood elevation vary lot by lot, so we confirm them for every waterfront home we show.

What should I know before buying a condo in Key Biscayne?

Read the documents as closely as the listing. Many island buildings date from the 1960s to the early 1980s, so the reserve funding, any special assessment and, for buildings three stories or taller, the milestone inspection and structural integrity reserve study matter. Communities such as Key Colony and the Ocean Club are made up of several associations, each with its own budget, and every association sets its own approval process and rules on pets and leasing, so ask for them before you offer.

What is my Key Biscayne home worth?

Request a free valuation and we build it from recent closed sales that match your home: for a house, the lot size, elevation, canal or bay frontage and condition; for a condo, the building, floor, exposure and view, rather than a village-wide median. For a listing decision we prepare a full comparative market analysis, and homeowners who need a fast sale can request a guaranteed cash offer.

Do you already have buyers looking for homes in Key Biscayne?

BreakThru Realty works with hundreds of prequalified buyers searching for properties. We keep each buyer's requirements on file: the neighborhoods, the price range, the property type and the features they are waiting for. Whether one of them fits your home is something a licensed broker checks for your property specifically, before the call. Your home may be the one a buyer is waiting to find; we confirm it before we call it a match, and a potential match is a conversation, not an offer.

Living in Key Biscayne

Key Biscayne is an island village south of Virginia Key, joined to the mainland near Brickell by the Rickenbacker Causeway, the only road on and off the island. The Village of Key Biscayne incorporated in 1991 and runs its own police, fire rescue, building department and parks. Crandon Park, a Miami-Dade County park with a beach, a marina and a golf course, fills the north of the island, and Bill Baggs Cape Florida State Park, home of the historic Cape Florida Lighthouse, fills the south. Between them, Crandon Boulevard carries the shops, restaurants, the Village Green and the community center. Key Biscayne K-8 Center is the public school on the island, and the MAST Academy magnet school is on Virginia Key, across Bear Cut.

Oceanfront Condos and the Beach

Most Key Biscayne homes are condominiums, and the best known line the Atlantic side of the island. At the north end, Key Colony on Crandon Boulevard and the Commodore Club on Ocean Lane Drive date from the 1970s and early 1980s. The Ocean Club on Crandon Boulevard groups towers and villas from the late 1990s and early 2000s, and the older buildings along Crandon Boulevard, Ocean Drive, Ocean Lane Drive and Grapetree Drive include the Towers of Key Biscayne, Casa del Mar, the Sands, Island House and Mar Azul. Oceana Key Biscayne on Ocean Drive and the Grand Bay buildings beside the Ritz-Carlton Key Biscayne are among the newer luxury addresses. For buildings three stories and taller, Florida's milestone inspection and structural integrity reserve study apply, and the reserves, any special assessment, the monthly fee and the leasing and pet rules decide the real cost of owning.

Single-Family Homes, Canals and the Bay

Single-family homes are the smaller share of the island and the hardest to find. They sit on quiet streets west of Crandon Boulevard such as Harbor Drive, Hampton Lane, Warren Lane, Curtiswood Drive and Glenridge Road, where early-1950s houses stand beside new two-story homes built to current flood elevation. Many of the waterfront homes are on Mashta Island in the bay and on the canals of the Cape Florida sections near the state park, where lots on Cape Florida Drive and the Pines Canal carry docks. Boats run straight out into Biscayne Bay, with the Atlantic around Cape Florida and Stiltsville on the flats to the south. For every home we check the flood zone and elevation, the roof and impact windows, and for waterfront lots the seawall, dock permits and water depth at low tide.

Neighborhoods

Key Biscayne buyers think in two halves: the oceanfront condominium communities and the single-family village behind them. On the ocean side, Key Colony and the Commodore Club hold the north end beside Crandon Park, and the Ocean Club groups its towers and villas around a lake on Crandon Boulevard. Behind them, Tropical Isle Homes and Biscayne Key Estates cover most of the single-family streets, and the Cape Florida sections at the south end pair canal estates with the Cape Florida Club condominiums near the state park. Each neighborhood page carries its live listings and recent sales, and the price, waterfront and property-type pages below cut the whole village the way buyers search it.

Selling a Home in Key Biscayne

Your Key Biscayne buyer may already be looking. BreakThru Realty works with hundreds of prequalified buyers searching for properties. Each one tells us the areas, the price range, the property type and the features they want, and we keep that on file. Before you list, a broker checks your home against those requests and prices it from recent MLS sales near it, and if no buyer on file fits, the plan reaches the rest of the market. A Key Biscayne home is priced by its water, its lot and its building as much as its square footage. For a house, lot size, elevation, canal or bay frontage, the dock and seawall, and whether it is original, renovated or new construction can separate two homes on the same street; for a condo, the building, floor, exposure, view and the association's finances do the same. Your buyers often compare Key Biscayne with Brickell, Coconut Grove and Miami Beach, so we price from the closed sales that match your home. Start with a free valuation built on recent MLS sales, ask for a full comparative market analysis, or request a guaranteed cash offer if you need a fast, as-is sale.

Investing in Key Biscayne

Investors on Key Biscayne usually buy one of three things: an original 1950s house to renovate or replace with new construction, a condo in an oceanfront building to lease on an annual or seasonal basis, or a large residence to use for part of the year and lease for the rest. Each has its own checks. A rebuild depends on the village's zoning and permits, the flood zone and the FEMA substantial-improvement rule, which requires an older home below flood elevation to be brought up to current standards once the work passes half its value. A rental depends on the village's rules on lease length and each association's approval process and leasing limits, so confirm both before you buy. The rental pages show live Key Biscayne rents, and the price-reduced page tracks sellers who have cut the price.
