Homes for Sale in St. Augustine, FL
True comps, carrying-cost math, and listings before the portals.
As of September 2026, the MLS records 5 closed sales in Castaway Cove in St. Augustine, FL since 2005, the most recent in April 2022. Across St. Augustine as a whole, 2,667 homes closed in the last 12 months at a median of $454,157, 53 median days on market, with 685 homes for sale today. At that median and St. Johns County's FY2025-26 rate of 13.47 mills, annual property tax runs about $6,120 ($5,600 with the full homestead exemption).
Castaway Cove is a small St. Augustine enclave in St. Johns County, and with a snapshot this tight the honest read is that price here is driven by condition and the specifics of each home rather than any published range. When inventory is this thin, one updated home closing high or one dated home closing low can move the picture more than any broad trend, so treat individual comps as the real signal.
For a buyer, that means underwriting the house in front of you, not the neighborhood average — the spread between move-in-ready and needs-work can be wide in a community this size. For a seller, it means presentation and preparation carry outsized weight: with few competing listings, a well-prepped home stands out, but pricing has to track actual recent closings rather than hope.
The 60-Second Overview
Castaway Cove is a compact St. Johns County community in St. Augustine, small enough that its market moves on individual sales rather than volume — which puts a premium on knowing recent comps street by street.

Who Castaway Cove is best for.
Best for
- Buyers targeting a small, established St. Augustine community who are patient enough to wait for the right listing

Probably not for
- Buyers who need a wide range of active listings to compare at any given time

The Castaway Cove buying strategy.
If we were buying in Castaway Cove 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 Castaway Cove.
A small-community market
The defining feature of Castaway Cove is scale. In a St. Augustine community this size, there is no deep pool of active listings to smooth out the data, so pricing is condition-led and comp-led. Two homes with the same footprint can sell far apart depending on updates, so the work is in reading each property honestly rather than leaning on a neighborhood number.
Location does the quieter work here. Sitting in St. Johns County near the St. Augustine area, the community draws on the broader access — coastal proximity, established road connections, and nearby services — that St. Augustine buyers tend to want. In a market with limited supply, that location context is often what keeps demand steady even when the listing count is low.
The location and the amenities are priced into every listing in Castaway Cove. The deal is won or lost on condition, the comps, and the renovation math.
