As of November 2026, the MLS records 11 closed sales in Island South in St. Augustine, FL since 2011, the most recent in May 2026. Across St. Augustine as a whole, 3,770 homes closed in the last 12 months at a median of $439,900, 50 median days on market, with 1,251 homes for sale today. At that median and St. Johns County's FY2025-26 rate of 13.47 mills, annual property tax runs about $5,920 ($5,410 with the full homestead exemption).
Island South sits within the St. Augustine market in St. Johns County, and pricing here tends to be driven more by the condition and specifics of the individual home than by any single neighborhood benchmark. Because the spread can be wide, two homes on the same street can trade very differently depending on updates, layout, and how they show.
For a buyer, that means the work is in the comparison — reading each listing on its own merits rather than assuming a going rate. For a seller, it means condition and presentation carry real weight; a well-prepared home tends to separate itself, while deferred maintenance shows up quickly in buyer feedback and time on market.
Figures in this note are as of July 12, 2026. The live market numbers elsewhere on this page update nightly and are newer.

The Island South buying strategy.
If we were buying in Island South 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 Island South.
How to read Island South
This is a community best understood home by home. Rather than a tight, predictable price band, you are looking at a range that reflects differences in size, condition, and finish. That rewards buyers who take the time to tour and compare, and it rewards sellers who invest in getting a home genuinely ready before it lists.
Location does the heavy lifting on lifestyle here: this is St. Augustine, in St. Johns County, with the coastal city's amenities within reach. Beyond that, we would rather point you to the specific home and its particulars than make sweeping claims we cannot back with the snapshot in front of us.
The location and the amenities are priced into every listing in Island South. The deal is won or lost on condition, the comps, and the renovation math.
