Executive Summary
Harbour Island is where Northeast Florida boating money ends its search: an island enclave inside Marsh Landing Country Club, wrapped around the only deep-water marina in Ponte Vedra Beach, a yacht basin reported at 94 slips and managed as a community resource.
The estates sit on lots of two or more acres along the Intracoastal, most with private docks in the backyard or slips in the basin, behind the Marsh Landing guard gate with the club golf and tennis minutes away.
For pricing context, estates have traded from about $2M past $8M, third-party and dated. Price a specific estate off the closest comparable sales, the lot, and the dockage.

Community Overview & History
The only deep-water basin in Ponte Vedra Beach
Plenty of Ponte Vedra homes touch water; almost none can hold a real yacht. Harbour Island is the exception, a protected deep-water basin inside the gates of Marsh Landing, which makes it the singular address for buyers whose boat is not negotiable.
How it feels on the ground today
Harbour Island reads as old-money quiet: the bridge onto the island, oaks over estate drives, yachts riding in the basin, and the Intracoastal opening west of every backyard. Turnover is rare and discreet.
The Community and What You Are Buying
Harbour Island is about the lot, the dockage, and the vintage of the estate.
Basin estates
Homes on the yacht basin pair protected slips with estate acreage.
Intracoastal-front estates
Big-water lots with private docks and western sunsets.
Vintage and renovation
Custom construction spans decades; renovation depth and architecture drive price.
Real Estate Market
Harbour Island appeals to UHNW boaters who need deep-water dockage with estate privacy and club access.
Estates have traded roughly $2M to $8M+, dated. Price off the closest comparable sales, weighting dockage heavily.
With one basin and a few dozen estates, supply is fixed forever.
Who Lives Here
Harbour Island draws serious boaters, executives, and athletes who want yacht-scale dockage behind two gates with Marsh Landing golf as the bonus.
Schools
Harbour Island is served by the top-rated St. Johns County School District, with attendance zones by home address. Confirm the exact zoning for a Harbour Island address before you buy.
Amenities & Lifestyle
The marina is the amenity; Marsh Landing provides the rest.
94-slip yacht basin
The only deep-water marina in Ponte Vedra Beach, managed as a community resource.
Private docks
Most estates carry backyard docks or basin slips.
Marsh Landing Country Club
Optional membership: golf, tennis, fitness, and dining inside the gates.
Double gates
The Marsh Landing guard gate plus the enclave entry.
HOA, CDD & Costs
Harbour Island carries the Marsh Landing master association plus its own sub-association; confirm both, plus basin and slip rules, transfer terms, and any waitlists.
For waterfront estates, verify dock permits, bulkheads, dredge depth at low tide, and insurance early.
Marsh Landing club membership is optional and separate; confirm categories and availability.
Commute Analysis
| Destination | Typical drive |
|---|---|
| The yacht basin | In the neighborhood |
| Marsh Landing clubhouse | Minutes inside the gates |
| The beach | About 10 minutes |
| Sawgrass Village | About 5 to 10 minutes |
| Mayo Clinic | About 15 minutes |
Harbour Island sits inside Marsh Landing minutes from JTB, so the beach, Mayo, and the Town Center run on the standard Ponte Vedra clock, while the Intracoastal runs from the backyard to anywhere.
Shopping & Dining
Sawgrass Village and the A1A corridor cover daily life minutes away, with the club dining inside the gates.

Hidden Things Buyers Should Know
Deep water is destiny
Sailboats and large motor yachts need depth the region rarely offers behind gates; the basin is why this enclave has no substitute.
Weight the dockage
Two similar estates diverge seven figures on slip rights and dock scale; appraise the water infrastructure like a second house.
Quiet market
Many Harbour Island trades never hit the open market; representation with club and corridor relationships matters here.
Momentum Expert Insight
Harbour Island is the one-of-one of Ponte Vedra boating: the basin, the acreage, and the gates exist together nowhere else in the zip code. Buyers who need it know immediately.
My advice is to underwrite the dockage and associations first, move discreetly and fast when an estate surfaces, and treat the basin slip as the asset it is.
Selling a Home in Harbour Island
Selling on Harbour Island is about presenting the dockage, the lot, and the estate to a national boating pool, often quietly, and pricing off the closest comparable sales.
We price from the most recent comparable estates, weight the water infrastructure correctly, and market discreetly to qualified boaters.

Flood Zones & Insurance
St. Johns County flooding concentrates near the Intracoastal, the coast, and the creeks and marshes, while many inland master-planned communities sit in lower-risk zones.
The reliable move is to pull the FEMA flood designation for the exact Harbour Island address before you write an offer, since two homes in the same area can fall in different zones. A home in Zone X can cost far less to insure than one near water in Zone AE. Get a bindable flood and homeowners quote during your inspection period, so the cost is in your monthly math before you commit, not after.
Internet & Connectivity
St. Johns County is well served by AT&T (fiber in most newer communities) and Xfinity (Comcast), though fiber availability still varies by street. If working from home matters, confirm the options, and fiber in particular, at the specific Harbour Island address rather than assuming.
The Tax Reality
St. Johns County total millage varies by district, and CDD assessments are common in the master-planned communities, which adds to the all-in cost on top of the millage. The Florida homestead exemption for 2026 is 51,411 dollars for those who qualify, and the deadline to file a new homestead exemption is March 1.
The trap to plan for is the post-sale reset: when you buy, the Save Our Homes cap from the previous owner ends and the assessed value resets to the new just value, so your second-year tax bill is often higher than the seller current one. Budget the true number, and confirm whether the specific home carries a CDD or other assessment that is billed separately from the millage and is not reduced by the homestead exemption.
What Your Budget Buys Here
The same budget buys very different homes across Harbour Island and the surrounding area, depending on age, size, lot, and condition. Rather than anchor on the asking price or the neighborhood average, price any specific home off the most recent comparable sales, and weigh what your money would buy in the nearby alternatives before you commit.The Future of the Area
St. Johns County continues to grow, with new rooftops, retail, and road work reshaping parts of the area. That growth supports long-run demand, but it can also add competing inventory and construction traffic in the near term, so factor both the upside and the disruption into your timing and your pricing.Resale Liquidity
How quickly a Harbour Island home resells comes down to presentation, condition, and pricing against the latest comparable sales rather than the neighborhood average. Homes that are priced correctly and shown well tend to move, while overpriced or dated homes sit. We track the active and sold comparable set so a Harbour Island home is priced to the real market.The Harbour Island Playbook
If you are buying in Harbour Island, here is how we would approach it: pull the flood zone and a real insurance quote for the specific address, confirm the HOA dues and whether a CDD applies, compare what your budget would buy nearby, and price the home off the closest comparable sales rather than the asking price. If you are buying any new-construction home, bring your own agent before you register, since the on-site representative works for the builder, not for you.
Questions We Would Ask Before Buying Here
Ask the seller
- What flood zone is this exact address in?
- What are the HOA dues, and is there a CDD or special assessment?
- What did the last few comparable homes actually sell for?
- How old are the roof, HVAC, and water heater?
- What is the true second-year tax estimate after reassessment?
Ask yourself
- Does the commute to work, schools, and daily life actually work?
- Do I need fiber internet, and is it at this address?
- Am I pricing against the right comparable sales, not the average?
- Does the lot and the condition fit my budget and my resale plan?
Mistakes to Avoid
The common ones around Harbour Island: trusting the seller current tax bill instead of the post-sale reset; skipping the address-specific flood check; assuming fiber is at every home; and pricing off the neighborhood average rather than the closest comparable sales. Each is avoidable with the right diligence, which is exactly where having your own agent pays off.
