Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending September 20 of each year, from record-level MIAMI MLS closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($8.25M) IS the median in the snapshot above, and the move from 2025 ($12.31M) IS the -33.0% one-year change.
Windows contain 0 to 12 sales each (6 in the current window); every figure carries its sample size, and thin markets swing on single closings. Based on information from the Southeast Florida Multiple Listing Service (SEFMLS) or from MIAMI Association of REALTORS(R) for the period 2012 through 2026. Deemed reliable but not guaranteed.

The San Marino Island buying strategy.
If we were buying in San Marino Island today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in San Marino Island.

At a median of $3556 per square foot, San Marino Island prices sit in a fairly defined band, so condition and updates — more than the list price — tend to separate one home from the next.
The trailing-12-month median down 33% year over year. Homes that do trade take a median 162 days on market, useful leverage on any listing that has lingered.
The location and the amenities are priced into every listing in San Marino Island. The deal is won or lost on condition, the comps, and the renovation math.
