True comps, carrying-cost math, and listings before the portals.
Sandy Lake is a community in St. Augustine, St. Johns County, FL. Across St. Augustine as a whole, 2,207 homes closed in the last 12 months at a median of $426,000, 47 median days on market, with 1,244 homes for sale today. At that median and St. Johns County's FY2025-26 rate of 13.47 mills, annual property tax runs about $5,740 ($5,220 with the full homestead exemption).
The defining feature is entitlement uncertainty. Sandy Lake is a rezoning proposal, not a product: 81 lots with a marina and park in one filing, up to 150 homes in another, and nothing approved. The value case cannot be assessed because there is no price, builder or schedule.
There is no purchase contract to review yet. What to verify as the process moves: the status of each filing with St. Johns County, the final approved lot count, who the builder will be, whether the marina is public or private, HOA or CDD structure, and any deposit terms if a pre-sale list opens. Treat any early reservation request with caution until approvals are in hand.
Figures in this note are as of October 30, 2026. The live market numbers elsewhere on this page update nightly and are newer.
The 60-Second Overview
Sandy Lake is a proposed single-family community with a marina near I-95 and CR 210 in St. Augustine, St. Johns County. It is at the land-use stage, not the sales stage. Seda Construction filed a Planned Rural Development request in July 2026 for 81 lots plus a marina and park on about 412 acres, with about 370 acres preserved. A separate agricultural enclave filing, made later in July 2026, covers up to 150 homes on about 379 acres. Neither request has been approved. No builder has been named, no pricing exists and there is no delivery timeline. Because approvals are pending, homes may never be built as described, and the plan could change.
Pre-construction details are compiled from public records, builder announcements and builder listings, and are subject to change without notice; figures are deemed reliable but not guaranteed. Momentum Research figures are our own analysis. This page describes homes, pricing and community attributes, not residents.

The Sandy Lake buying strategy.
If we were buying in Sandy Lake 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 Sandy Lake.
