Over the recorded series, CASA DEL MAR CONDO’s median sold price moved from $1,425,000 (2019) to $2,220,000 (12 months ending 2026-09-20) — +56% over that span, with every year’s figure from recorded closings, not a model.
The recorded series starts in 2019 at $1,425,000. The 2020–22 run-up did what it did everywhere — CASA DEL MAR CONDO’s median moved +25% from 2019 to 2022. Annual sales volume here has ranged from 2 to 16 closings a year (10-yr average 7.9). With roughly 7.9 closings a year, CASA DEL MAR CONDO’s medians move in steps, not curves — a handful of unusual sales can swing a year, which is why the sales count sits next to every figure above.
Of the 13 recorded CASA DEL MAR CONDO closings since 2024, half landed between $1,570,000 and $1,995,000 (the middle two quartiles); the lowest recorded sale was $690,000 and the highest $3,120,000. If your home sits outside the middle band, the reason usually shows up in the size table below before it shows up in condition.

From the live MLS feed as of 2026-09-23: 4 active listings (plus 0 pending) asking from $2,400,000 to $3,750,000, median $3,597,500; 1 of 4 have been on the market over 60 days (median 25 days so far); the homes listed or recently sold were built between 1971 and 1971 (median 1971); 4 of 4 listed or recently sold homes report an HOA, median $2,251/mo. For a seller this is the competition a buyer will tour alongside your home; for a buyer, the stale share is where negotiating room usually is. See the current CASA DEL MAR CONDO listings →
At CASA DEL MAR CONDO’s $2,220,000 median and Miami-Dade County’s adopted 17.59 mills (FY2025-26), a home assessed at that price carries roughly $39,060 a year in property tax before exemptions, or about $38,340 with the full Florida homestead exemption — a buyer’s first-year figure; a long-time owner’s Save Our Homes cap can be far lower, which is one reason resale taxes jump at closing. Municipal and special-district millage varies inside the county; see the Miami-Dade County tax page.
Current asking prices run a median $3,597,500 against the $2,220,000 recorded sold median (+62%) — the gap between what sellers hope and what the record shows. Demand check: 0% of CASA DEL MAR CONDO’s listings are under contract, against 15% for ZIP 33149 and 18% for Miami-Dade County as a whole — the community is currently absorbing slower than its surroundings, which is negotiating information. Momentum’s market-heat index for CASA DEL MAR CONDO reads 59/100 (computed from DOM, sale-to-list, and absorption; 2020–21 peaked in the 70s here).
With asking prices running +62% over the recorded sold median, a CASA DEL MAR CONDO listing priced against the closed record above stands out against its competition; one priced against the asking crowd joins the statewide list of homes that never sold.
