What Homes in Biscayne Key Estates Are Selling For

8 homes closed in Biscayne Key Estates in the last 180 days at a median of $4,575,000, or $1,248 per square foot, after 215 days on the market on average, and sellers achieved 94.2% of asking.

With a small number of sales a single large or small home can move a median, which is why a valuation works from the individual closings rather than from this figure.

What Buyers Pay For in Biscayne Key Estates

Biscayne Key Estates is a single-family subdivision on streets such as Curtiswood Drive, Woodcrest Road, Glenridge Road, Ridgewood Road, Warren Lane and Harbor Lane, with corner lots and some larger interior lots. Homes range from original early-1950s houses to elevated Mediterranean and colonial houses from the 1990s and 2000s and new modern builds, many with pools and usually with no association fee. Buyers here compare lot size, elevation, the age of the roof and windows, and whether the house can be renovated or is priced as land. Those are the things a Biscayne Key Estates buyer compares from one home to the next, and they are what separate a sale at the top of the range from one at the bottom.

Biscayne Key Estates Against the Key Biscayne Average

A Key Biscayne-wide figure blends every neighborhood, every property type and every condition. Biscayne Key Estates has its own buyers and its own price range, so a home here is valued against Biscayne Key Estates closings first and against the nearest comparable streets only when there are too few. There are 12 homes for sale in Biscayne Key Estates today at a median asking price of $5,539,000, about 9 months of supply: that is the competition a new listing is priced against.
