SEXTON COVE
Homes for Sale in Key Largo, FL
True comps, carrying-cost math, and listings before the portals.
Sexton Cove is a waterfront community in Key Largo where the price is driven almost entirely by water access and lot position, not square footage. At a median of $1,260,000 on roughly 1,178 square feet of living space, buyers are paying a significant premium per square foot relative to most mainland markets — and that is entirely expected in the Florida Keys. The spread across build years from 1960 through 2024 means condition varies widely; an older concrete home on a canal and a newer elevated structure can carry very different real costs even when listed near the same figure.
With only five closings in the current measurement window and a median days-on-market of 70, this is a slow, thin market. Pricing discipline matters on both sides: sellers who overshoot sit, and buyers who lowball serially miss the genuine opportunities. The homestead share of roughly 30 percent signals that the majority of ownership here is investment, vacation, or second-home oriented — which affects negotiating dynamics and the likelihood of off-season price adjustments.
The 60-Second Overview
SEXTON COVE market snapshot (as of July 27, 2026): the median sale price is about $1.26M, and a median 70 days on market for closed sales.
SEXTON COVE is a community of 331 homes in Key Largo, Monroe County, built between 1960 and 2024 (median 1985), with a median living area of about 1,178 square feet. 30% of parcels are homesteaded, the owner-occupancy proxy in the Florida DOR assessment roll (2025 roll, public records).
Sexton Cove sits within Monroe County's Florida Keys corridor, where land is finite and water-access lots define value far more than interior finishes or living area — context that explains a seven-figure median against a modest typical footprint.
Who SEXTON COVE is best for.
Best for
- Buyers with a clear waterfront-access priority, a seven-figure budget, and tolerance for a slower, thinner market where patience is part of the strategy.
- Second-home or vacation-property buyers who plan to hold long-term and have underwritten the full carrying cost picture including Keys insurance and flood zone expenses.
- Investors or end-users who are prepared to do thorough physical and regulatory due diligence on older stock and see value in a supply-constrained island corridor.
Probably not for
- Buyers who need a fast close or are working with a budget that leaves no room for insurance sticker shock and potential post-inspection renegotiation.
- Anyone expecting a broad selection of active listings — the thin transaction volume means choice is limited and waiting for the right property can take time.
- Buyers prioritizing square footage or interior scale over location; the median footprint here is modest, and value is almost entirely in the land and water access, not the living area.

The SEXTON COVE buying strategy.
If we were buying in SEXTON COVE 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 SEXTON COVE.
What the numbers actually mean in Sexton Cove
The median living area of roughly 1,178 square feet tells you this is not a community of large houses — it is a community of valuable locations. Homes built as far back as 1960 coexist with construction completed through 2024, and the median build year of 1985 places the typical home in an era before current Florida wind and flood standards were fully codified. That matters for insurance underwriting, required upgrades, and long-term carrying costs. Buyers should budget for due diligence on elevation certificates, FEMA flood zone designation, and the current condition of seawalls or dockage before fixating on the list price.
The since-2012 appreciation figure of 509 percent is a historical observation, not a forward projection. It reflects a combination of Keys scarcity, post-pandemic demand for waterfront lifestyle properties, and the fundamental supply constraint of island geography. What it does not tell you is where any individual property sits relative to the median, whether deferred maintenance has eroded value, or how a given home's flood-zone exposure affects insurability today. Those are the questions that actually determine whether a specific acquisition at or near the median makes sense.
