Market Heat

Porpoise Point Sec 4 sits on Big Coppitt Key in Monroe County, putting it squarely in the Florida Keys — a market where land scarcity and water access drive pricing more than finished square footage. The median of $870,000 reflects that geography premium; what separates one transaction from another here is typically lot position, water frontage, dock rights, and storm-hardening construction quality, not just bedroom count.
The current market posture is worth reading carefully. A 19.1% year-over-year price decline against a median DOM of 41 days and a market heat score of 50 signals a market in rebalancing mode — sellers are moving product, but at a meaningful concession from last year's peak. Only seven closings anchor this window, so a single outlier can shift the median materially. Buyers have more negotiating room than they did twelve months ago; sellers who need to move quickly should price ahead of that trend rather than chase it.

The 60-Second Overview
PORPOISE POINT SEC 4 market snapshot (as of July 27, 2026): the median sale price is about $870K, and a median 41 days on market for closed sales. The trailing-12-month median is down 19% from the prior 12 months and up 164% since 2012, computed from record-level floridakeys closed sales (7 closings in the current window).
Porpoise Point Sec 4 is a small, water-oriented enclave on Big Coppitt Key where Monroe County's tight land supply keeps the floor elevated even as the broader Keys market digests a post-peak correction — the long-run picture, up roughly 164% since 2012, anchors the context for today's pullback.
Who PORPOISE POINT SEC 4 is best for.
Best for
- Cash or low-leverage buyers with a 7-plus-year horizon who want a deeded Keys address and can absorb Monroe County insurance and maintenance costs without stress
- Buyers actively seeking water-oriented lots or dock-capable properties and willing to do granular due diligence on frontage type and permitting status
- Investors or second-home buyers who have already owned in the Keys, understand the carrying cost structure, and see the current correction as a re-entry window
Probably not for
- Buyers expecting to resell within two to three years and require predictable short-term appreciation to pencil the deal
- Budget-constrained buyers who need to negotiate a price well below the current median to qualify — at this price point, even a modest concession still requires substantial capital reserves for insurance, flood mitigation, and maintenance
- Buyers who have not yet underwritten Monroe County's wind and flood insurance market — the cost structure here can materially change the economics of a purchase that looks attractive on sale price alone

Median sale price over the trailing 12 months ending July 27 of each year, from record-level floridakeys closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($870K) IS the median in the snapshot above, and the move from 2025 ($1.08M) IS the -19.1% one-year change.

The PORPOISE POINT SEC 4 buying strategy.
If we were buying in PORPOISE POINT SEC 4 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 PORPOISE POINT SEC 4.
Reading a thin, high-value market
Seven closings is a narrow data set, and in a community like this that is by design — there simply are not many addresses. That thinness cuts both ways: a single distressed sale or an exceptional waterfront closing can move the reported median by a six-figure margin in either direction. Buyers should resist anchoring too hard to the median as a per-property benchmark and instead focus on comparable lot characteristics — frontage type, canal versus open-water exposure, seawall condition, and permitted dock infrastructure — because those variables explain the spread more reliably than bedroom count.
The year-over-year decline of roughly 19% is notable but not unprecedented for the Keys after an outsized run-up. The long-cycle appreciation since 2012 underscores that corrections here have historically been interruptions rather than reversals, though past performance is not a forward guarantee. For a buyer, the 41-day median DOM suggests the market is not panicked; properties are clearing, just at adjusted prices. For a seller, the message is that overpricing relative to current comparable data will cost more time than the initial ask is worth.
