This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
$799,699the mess$912,292
Actual list price: $745,900 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 14% spread on the same house — and that gap is exactly what an automated guess can't see:
Condition & updates — a renovated kitchen or new roof vs. dated finishes can swing value six figures; sq ft can't see it.
The lot & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
Outliers skew it — one flip or distressed sale in the comps drags the whole $/sq ft up or down.
Carrying costs & concessions — CDD, HOA, insurance, and seller-paid buydowns change what a buyer actually pays.
And here's what the live market is doing — which the number above ignores entirely:
This home: 121 days on market vs. a 32-day community median
9 active listings competing, 2 under contract
≈3.4 months of supply
31 closed here in the last 12 months
For reference, this home is listed at $745,900 ($258/sq ft) — a number set with analysis a Messtimate can't do.

CR 210 widening westbound lanes set to reopen in St. Johns County
News4Jax reported that all westbound lanes of the County Road 210 widening project in St. Johns County were expected to reopen by the end of Friday, July 31, 2026, ahead of the August 10 school year start. The county said it is managing 44 active road projects totaling $183.1 million this year.
Why it matters: Expands roadway capacity on a major county corridor, improving traffic flow and supporting continued growth along the CR 210 area. The project is about 8 miles east of Julington Lakes, elsewhere in St. Johns County.
Six agricultural enclave projects seek to develop 6,500-plus acres in St. Johns County
Jacksonville Today reported that St. Johns County received six proposals totaling more than 6,558 acres for development under a new Florida agricultural enclave law that took effect July 1, 2026. The largest proposal, about 4,462 acres north of Nocatee, comes from the Davis family and the PARC Group. The County Commission scheduled a public hearing on the proposals for August 19, 2026.
Why it matters: Signals a large potential expansion of developable land and future housing and commercial capacity, using a new state process that can convert farmland to residential and commercial use with reduced local review. The project is about 10 miles east of Julington Lakes, elsewhere in St. Johns County.
Publix opens and more retailers coming to Marketplace at Nocatee
An official Nocatee business update reported that a Publix supermarket with a pharmacy drive-thru and adjacent Publix Liquors has opened at Marketplace at Nocatee. Additional announced tenants include SoFresh in late summer 2026, a Gate gas station, BODYBAR Pilates, a nail spa and a wine and spirits shop. The Hub at Nocatee entertainment concept is slated for 2028.
Why it matters: Expands grocery, dining and everyday retail capacity at a growing town center, adding anchor and service tenants that build out the commercial base of the area. The project is about 10 miles east of Julington Lakes, elsewhere in St. Johns County.
First Coast Expressway advances as an economic-development corridor across Clay and St. Johns
The First Coast Expressway (State Road 23), a tolled beltway looping around the west and south of the Jacksonville metro, continued to open land for development along its corridor, with the final St. Johns County phase from Interstate 95 to east of County Road 2209 in progress. FDOT held a St. Johns County open house on the final phase in January 2026.
Why it matters: New limited-access highway capacity shortens commutes and opens adjacent land, changes that have historically shaped where new communities and demand concentrate. The site is about 10 miles southwest of Julington Lakes.

Answered before you ask
Frequently asked questions
Why might my property taxes differ from the current owner's?
Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment can be re-set after a sale. As a result a new owner's bill may differ from the seller's. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Where does the flood-zone information come from?
The flood designation shown (Zone X) comes from the FEMA flood map and is provided for general information. Confirm the parcel's status with FEMA and your insurer.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
