Jon's Current Read

"The Sanctuary is one of Boca Raton's most exclusive addresses, a guard-gated Intracoastal enclave of 97 custom estates with a private marina, deep-water canals, and round-the-clock land and water security, named among the country's most exclusive gated communities. The read is trophy waterfront with fortress-level security: estates from roughly 5,000 to over 20,000 square feet, deep-water dockage and a 20-slip marina, and a 27-acre preserve, near Mizner Park and the beach. The buy turns on the frontage and dockage, the seawall, an honest read of a bespoke estate, and the HOA and security structure."

Jon Brooks, founder, Momentum Realty · Updated June 2026

The 60-Second Overview

The Sanctuary market snapshot (as of June 15, 2026): the median sale price is about $4.0M ($472 per sq ft), with homes averaging 590 days on market and 12.0 months of supply, a buyer-leaning market (limited data). Based on 3 recent closings in live BeachesMLS data.

The Sanctuary is a small, private, guard-gated enclave of 97 custom luxury estates on the Intracoastal Waterway in Boca Raton (ZIP 33431), Palm Beach County, listed among Forbes' most exclusive and expensive gated communities in the United States (The Sanctuary profiles).

Estates range from roughly 5,000 to over 20,000 square feet, with values reported well into the eight figures, on deep-water canals with private dockage.

Amenities include a 20-slip private marina, Har-Tru tennis courts, and a roughly 27-acre bird and wildlife preserve, with uniformed land and water patrols and armed security at the main and service entrances and throughout the deep-water canals.

Because these are trophy waterfront estates with a dedicated security operation, value turns on the frontage and dockage, the seawall and condition, and the HOA and security structure. Confirm the dock and route for your vessel, read the seawall and the estate, and confirm the HOA before you offer.

Best for

  • Buyers seeking an ultra-exclusive, fortress-secure waterfront estate in Boca Raton
  • Yacht owners who want deep-water dockage and a private marina
  • Buyers who will read the frontage, seawall, and a bespoke estate honestly

Probably not for

  • Buyers seeking an attainable price or a low carrying cost
  • Buyers who want an inland or non-waterfront home
  • Buyers unwilling to underwrite trophy-waterfront insurance, seawall, and security costs

Tight supply and strong demand favor sellers here. Homes still take about two months to sell, though, and with asking prices running above recent sales per square foot, a prepared buyer has room on anything overpriced. Reading each home against the real comps, not the headline trend, is where the edge is.

    Ultra-exclusive guard-gated Intracoastal enclave of 97 estates

    The Sanctuary is a guard-gated Boca Raton enclave of 97 custom estates (roughly 5,000 to over 20,000 square feet) on deep-water Intracoastal canals, with a 20-slip marina, Har-Tru tennis, a 27-acre preserve, and armed land and water patrols (community profiles; Forbes). Treat figures as reported and confirm. Why it matters: Exclusivity, security, and deep-water dockage are the value; read the frontage, the seawall, and the estate. Source

If we were buying in The Sanctuary, this is the order of operations we would run, and the one we run for our clients.

1

Confirm the frontage and dockage, the canal depth, the dock, any marina slip availability, and the route to the inlet for your vessel.

2

Inspect the seawall and dock, not just the house, since they are major waterfront line items on a trophy estate.

3

Confirm the HOA and security structure, the dues, the armed patrols, and the marina arrangement.

4

Read a bespoke estate honestly, the roof, systems, and finish, and get a trophy-waterfront insurance quote.

5

Comp within The Sanctuary, since this is a thin, unique market that does not compare to other communities.

Best Buy
An estate with strong deep-water frontage and dockage for your vessel, a sound seawall, and a defensible condition read.
Biggest Risk
A failing seawall, limited dockage, or uninsurable systems on a bespoke estate you did not price.
Best Lot
Maximum deep-water frontage and dockage with the best preserve or water views command the highest premiums.
Smart Timing
Confirm the dockage, the seawall, the HOA and security, and insurance before you write.

Community Details at a Glance

The Sanctuary is a guard-gated, ultra-exclusive enclave of 97 custom estates (roughly 5,000 to over 20,000 square feet) on the Intracoastal Waterway in Boca Raton (33431), with a 20-slip private marina, deep-water canals, Har-Tru tennis, a roughly 27-acre preserve, and uniformed land and water patrols with armed security. It is listed among the most exclusive gated communities in the country. Carrying costs are trophy-waterfront insurance, the seawall and dock, condition, and a security-heavy HOA; confirm all. It is near Mizner Park and the beach and zoned to Palm Beach County public schools by address; verify with the district.

The takeaway

Three honest price bands. Condition and lot, not the square footage alone, decide where a home lands.

Entry: estates needing updates
$1.10M to $3.99M

Even the lower end here is trophy-tier; estates needing updates still command Sanctuary pricing. Confirm the seawall, dockage, and insurance before assuming value.

Lowest entry
Mid: updated estates with strong dockage
$3.99M to $7.68M

The core is updated estates with strong deep-water dockage. Frontage, dock capacity, and condition separate these in a thin market.

Most inventory
High: new and reimagined mega-estates
$7.68M to $7.68M

The top end is new and reimagined mega-estates with maximum frontage, well into the eight figures. These trade on the frontage, the dockage, and the finish.

15-Second Take
  • Renovation math decides the deal
  • Better lots and views resell strongest
  • Roof and HVAC age drive the insurance quote
  • Interior lots are where buyers overpay
Jon Brooks, Momentum Realty
Operator Note

Most buyers overpay on interior lots in the back half of the community. A sharp renovation can distract you, but the weaker resale position follows the lot, not the finishes. We read the homesite before the kitchen.

Momentum analysis based on the community's structure, location, lot scarcity, and housing stock. Not a guarantee of future value.

Jon Brooks, Momentum Realty
Operator Note

The strongest value pocket is usually a renovated home on a good lot priced just under the next tier up. Buyers chasing the single biggest house often pay top prices for what is really a renovation project.

5 Mistakes Buyers Make in The Sanctuary

15-Second Take
  • Calling the listing agent (who works for the seller)
  • Misjudging the renovation budget
  • Overpaying for an interior lot
  • Underbudgeting the carrying costs
  • Skipping the roof, HVAC, and systems check

The same five mistakes cost buyers the most in any market. Every one is avoidable with the right preparation before you tour.

The exclusivity, the armed security, and the deep-water dockage are priced into every Sanctuary listing. The deal is won on the frontage, the dockage, the seawall, and the estate, not the sticker.

Which Lots & Views Hold Value Best

Where the value actually sits. Each home is shaded by its price per square foot (a value read, not just a price) and ringed by lot type, so you can see at a glance which pockets carry a real, durable premium and where a renovation play makes sense.

Value ($/sqft)
$261 value$401 premium
Lake / waterPreserveInterior

Fill = price per square foot; ring = lot type, inferred from listing descriptions. Sold homes are shown by realized $/sqft (lot type not always recorded). Asking and recent-sold figures from BeachesMLS; for orientation, not an appraisal.

15-Second Take
  • Maximum deep-water frontage and dockage command the top premium.
  • The seawall and dock drive value alongside the frontage.
  • A thin, trophy market means each estate is unique.

In a trophy enclave like The Sanctuary, the deep-water frontage and dockage set value alongside the seawall, the security, and the estate. Maximum frontage with strong dockage and the best views commands the highest premium. Compare an estate only within The Sanctuary, and read the dockage and seawall before the finishes.

HOA, CDD & Fees

15-Second Take
  • The HOA funds armed land and water patrols and the marina.
  • Deep-water dockage and a 20-slip private marina.
  • Trophy-waterfront carrying costs: insurance, seawall, dock.
  • Confirm the dock and marina slip for your vessel.
  • Comp within The Sanctuary, a thin, unique market.

The Sanctuary carries an HOA that funds an unusually heavy security operation (uniformed land and water patrols, armed entrances) plus the private marina and common areas; treat any figure as reported and confirm the current dues, the security and marina arrangements, the reserves (including seawall and docks), and any assessment before you offer.

The HOA generally covers the guarded entrances, the land and water patrols, the marina, the preserve, and common areas; confirm exactly what is included and the marina-slip arrangement.

There is no golf club; amenities are the 20-slip private marina, Har-Tru tennis courts, and a roughly 27-acre bird and wildlife preserve. Confirm the marina availability and any rules.

The takeaway

Selling here is won on condition and view, not the Zestimate. The right number comes from closed comps matched to your renovation level and lot.

In The Sanctuary, condition and view decide your number

Because buyers here are weighing your home against renovated comps and cross-shopping The Sanctuary, a home priced to the community average instead of its true condition and view either leaves money on the table or sits. A renovated kitchen, newer roof and HVAC, and a golf or lake view all deserve to show up in your price, and a buyer pool reading renovation math needs to be shown why your home is worth it. We build that case with real comps and a pricing strategy for the current market.
