Homes for Sale in St. Augustine, FL
True comps, carrying-cost math, and listings before the portals.
As of September 2026, the MLS records 77 closed sales in Six Mile Sub in St. Augustine, FL since 2005, the most recent in June 2026. Recorded prices across those 77 sales ran from $90,000 to $1,199,000 (median $290,000), on homes of 875 to 4,397 sq ft. Across St. Augustine as a whole, 2,670 homes closed in the last 12 months at a median of $453,314, 52 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 $3,910 ($3,390 with the full homestead exemption).
The honest read on Six Mile Sub is that this is a thin-data community as of July 2026 — the closings window here is narrow, so there is no deep pool of recent sales to anchor a price. What sets value in a pocket like this is the individual home: condition, lot, updates, and how it stacks against the broader St. Augustine and St. Johns County market rather than a dense set of neighborhood comps.
For a buyer, that means pricing is negotiated on the merits of the specific house, not dictated by a run of look-alike sales. For a seller, it means presentation and a defensible comp story matter more than usual — you cannot lean on a wall of recent neighborhood closings to justify a number, so the case for price has to be built deliberately.
The 60-Second Overview
Six Mile Sub is a small St. Augustine pocket in St. Johns County where sales activity is light enough that each transaction stands largely on its own. Treat it as a place where the home, not the crowd, tells the story.

Best for
- Buyers who want a quiet St. Augustine location and will underwrite a home on its individual condition
- Long-hold buyers who are not trading on short-term flips or quick resale
- Sellers willing to invest in presentation and a built-out comp case rather than relying on neighborhood volume
Probably not for
- Buyers who need a deep bench of recent neighborhood sales before committing
- Investors chasing quick turnover in a high-liquidity submarket
- Anyone who wants a fast, comp-driven pricing decision with minimal legwork

The Six Mile Sub buying strategy.
If we were buying in Six Mile Sub 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 Six Mile Sub.
A thin-comp pocket in St. Johns County
With only a narrow closings window on record as of this snapshot, Six Mile Sub does not give you the statistical comfort of a high-turnover subdivision. That is not a red flag on its own — plenty of established St. Augustine pockets simply trade infrequently — but it changes how you underwrite a purchase or a sale here. Expect to spend more time on the physical asset and on comparables drawn from the wider area.
Practically, that puts a premium on a careful walk-through and an inspection-driven view of condition. Because there is no dense sales history to lean on, a strong offer or a strong list price is one that is documented and defensible rather than assumed from neighborhood momentum.
The location and the amenities are priced into every listing in Six Mile Sub. The deal is won or lost on condition, the comps, and the renovation math.
