JSR has a separate post on recorded resales on Fisher Island, and a wider one on how often a Miami condo actually trades. On the pre-construction side, see JSR’s guide to The Delmore in Surfside.
How these numbers are counted
Every figure here comes from the Miami-Dade County Property Appraiser’s public record, pulled by JSR on 23 September 2026. A “sale” is a deed the county marks as a qualified, arm’s-length sale of a home in the building. Transfers between related parties, foreclosure deeds the county does not qualify, and single deeds that move several units at once are left out, because one package price split across units distorts the picture.
The window is the 12 months before each building’s county pull. We publish the count, the median price, the median price per square foot and the date of the latest recorded sale. We do not publish a low-to-high range: one package deed can make a range meaningless while barely moving a median. Where a building recorded one or two sales, there is no median; two sales are not a market.
These are the same figures that appear at the top of each building’s page on this site. They are recorded closings, not asking prices, and the record lags the closing table by a few weeks.
One limit to know. These are the buildings that have a JSR building page carrying a county-record 12-month figure. They are not every condominium in the three places: Fisher Island, for example, has other condominium buildings that are not in this count, so the Fisher Island figures below describe three buildings, not the island.

On the Miami-Dade County Property Appraiser record pulled 23 September 2026, Ocean Seven recorded one sale, on 30 April 2026, so no median is printed, and there is no sale in the window at Arte Surfside or Azure Condos, whose latest recorded sales are dated 30 June 2025 and 18 December 2024, both before the 12-month window opens.
One building accounts for most of Surfside’s recorded sales: on the Miami-Dade County Property Appraiser record pulled 23 September 2026, The Surf Club Four Seasons has 12 of the 17 and, with The Waves, 16 of the 17.

On the Miami-Dade County Property Appraiser record pulled 23 September 2026, 101 Key Biscayne recorded no sale in the window, with its latest recorded sale dated 14 August 2024, before the window opens, and Grand Bay Residences’ latest recorded sale (6 February 2026) is the earliest of the six buildings that recorded three or more sales.
Reading small numbers
Three of the six buildings with a median had only three or four recorded sales on the Miami-Dade County Property Appraiser record pulled 23 September 2026, and a median of three or four sales is a marker, not a price list: one more or one fewer deed moves it. What is more useful in buildings this size is the date of the latest recorded sale, the unit’s own line and floor, and the sales in your own tower. The county record shows each home’s sale history and assessment history, which is how you check what the tax roll thinks a home is worth.

What is the median condo sale price on Fisher Island?

What do condos sell for on Key Biscayne?

Why do some buildings show no median price?

What counts as a sale in these figures?
On the Miami-Dade County Property Appraiser record pulled 23 September 2026, a sale is a deed the county marks as a qualified, arm’s-length sale of a home in the building; related-party transfers, foreclosure deeds the county does not qualify and single deeds that move several units at once are left out, and the figures are recorded closings, not asking prices.
Does this cover every condo on Fisher Island, Surfside and Key Biscayne?
No, the count covers only the 11 buildings that have a JSR building page with a county-record 12-month figure on the Miami-Dade County Property Appraiser record pulled 23 September 2026, so other condominium buildings, including others on Fisher Island, are not in it.
