Market Heat
At a median of $975,000 and a median days-on-market of roughly 136 days, this Key West community is operating at a deliberate pace. The market-heat score of 25 confirms it: buyers are not competing frantically, and sellers are waiting out the process. That combination — near-seven-figure pricing alongside extended marketing times — tells you supply is not scarce here, or buyer pools at this price point are selective, or both.
The year-over-year gain of 16.1 percent is meaningful context for any negotiation, but it does not override the reality that homes here are sitting for months before closing. A seller who prices aggressively will feel that DOM figure acutely. A buyer who does the homework has room to negotiate without walking away from a genuinely appreciating asset class.

The 60-Second Overview
1800 ATLANTIC market snapshot (as of July 27, 2026): the median sale price is about $975K, and a median 137 days on market for closed sales. The trailing-12-month median is up 16% from the prior 12 months and up 175% since 2012, computed from record-level floridakeys closed sales (6 closings in the current window).
Situated in Key West within Monroe County, this community has posted cumulative price growth of 175 percent since 2012, yet the current market posture is decidedly measured — extended selling timelines and a low heat score suggest that patience, not urgency, drives transactions here.
Who 1800 ATLANTIC is best for.
Best for
- Buyers targeting a Key West address near the $975,000 median who can absorb a multi-month escrow timeline without financial strain.
- Sellers who understand that the current heat score of 25 requires precise list-price discipline and a willingness to negotiate on condition-related adjustments.
- Long-horizon buyers who view the 175 percent cumulative gain since 2012 as evidence of durable price strength and are not dependent on a near-term exit.
Probably not for
- Buyers who need to close on a firm short timeline — the median days-on-market suggests the process here routinely runs well beyond four months.
- Buyers whose purchase decision depends heavily on documented on-site amenities, since none have been identified from current MLS listings.
- Anyone whose budget requires pricing meaningfully below the median — this market has no identified entry-level tier, and the data does not support assuming one exists.
Price History: What Homes Here Have Actually Sold For
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 ($975K) IS the median in the snapshot above, and the move from 2025 ($840K) IS the +16.1% one-year change.
Windows contain 3 to 18 sales each (6 in the current window); every figure carries its sample size, and thin markets swing on single closings. Listing data provided by Florida Keys MLS, Inc.

The 1800 ATLANTIC buying strategy.
If we were buying in 1800 ATLANTIC 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 1800 ATLANTIC.
Reading the Slow Burn
A median days-on-market approaching five months is not a distress signal in an ultra-premium Key West address — it is a structural feature of a thin buyer pool at this price tier. Only a limited number of closings occurred in the most recent six-month window, which means each transaction carries outsized weight in any pricing analysis. One outlier sale in either direction shifts the median noticeably, so buyers and sellers alike should treat the $975,000 median as a directional benchmark, not a ceiling or floor.
No community amenities have been identified from current MLS listings. That absence shifts the value conversation entirely to location and the physical attributes of individual units — finishes, views, condition, and flood-zone standing all become the primary price drivers. In a market where carrying costs are real and days on market are long, condition-adjusted pricing matters more than headline comparables.
The location and the amenities are priced into every listing in 1800 ATLANTIC. The deal is won or lost on condition, the comps, and the renovation math.
