Three closings is not a market, it is a data point, and that is the first thing to understand about NAUTILUS EXTENSION 4TH. At a median price of $2,150,000 and $847.46 per square foot, this is a high-dollar, low-volume corner of Miami-Dade where a single unusual sale can swing the numbers more than actual demand does.
The 179-day median days on market and the -11.5% year-over-year move point the same direction: pricing here has been softening and sellers who list at aspirational numbers are sitting. With this few closings, buyers have real room to negotiate on terms and timeline rather than reacting to a fast-moving comp set.

🔴 Off the recent peak. The trailing-12-month median ($2.15M) is down 11.5% from the prior 12 months ($2.43M). With about 2 sales a year, a single closing can swing this number, so read the level and the decade, not one year's move.Momentum Research, record-level MIAMI MLS closed sales, 12-month windows ending September 20. Confidence: Low (3 and 4 sales in the two windows).

Source: MIAMI REALTORS closed-sale history compiled by Momentum Research; counts reflect homes with a recorded MLS sale, not every home in the community.
NAUTILUS EXTENSION 4TH trades at a median of $2,150,000, but with only three closings in the current window, that figure should be read as a snapshot of a thin, high-end micro-market rather than a stable trend line.
Who Nautilus Extension is best for.
Best for
- Buyers targeting a higher price point who are prepared to evaluate a small handful of comparable sales in detail
- Buyers comfortable with a longer purchase timeline given the extended median days on market
- Sellers who can price patiently rather than testing the market at a premium given the recent year-over-year decline
Probably not for
- Buyers who want a broad, active inventory to compare before deciding
- Sellers expecting a fast sale given the 179-day median days on market
- Anyone relying on amenity offerings, since none are identified from current MLS listings

The Nautilus Extension buying strategy.
If we were buying in Nautilus Extension 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 Nautilus Extension.
A Thin Market at a High Price Point
At $847.46 per square foot, per-square-foot value here sits well above typical Northeast Florida norms, which is consistent with a market defined by scarce, higher-end inventory rather than broad-based demand. With so few transactions to draw from, buyers should treat any single closing as a data point to investigate, not a rule to price against.
The 179-day median days on market is the number that matters most for negotiation strategy. Homes here are not moving quickly, and combined with a year-over-year decline of 11.5%, it suggests sellers who priced ambitiously earlier are now adjusting, or waiting out a buyer who is willing to pay full freight. Either way, the current posture favors patience over urgency.
The location and the amenities are priced into every listing in Nautilus Extension. The deal is won or lost on condition, the comps, and the renovation math.
