Four closings is a thin data set, and that matters more than any single number here. With a median price of $4,675,000 and a median price per square foot of $1,145.79, Nautilus Extension 5th is trading at a level where each sale carries outsized weight on the averages — a single unusually large or unusually finished home can swing the median substantially.
The reported 67.0% year-over-year change is the headline, but on a base this small it should be read as a signal to dig into the individual comps rather than a stable market trend. A median 132.5 days on market tells you these homes are not moving quickly, which is typical at this price point — buyers here take their time, and sellers who price against outdated comps often sit.

Who Nautilus Extension is best for.
Best for
- Buyers targeting the upper end of the price spectrum who are comfortable underwriting off a small set of comparable sales.
- Sellers with a distinctive, well-finished property who can wait through a longer-than-average marketing period for the right offer.
- Buyers or sellers who want a detailed, sale-by-sale comp review rather than a quick median-based estimate.
Probably not for
- Buyers who need a large, liquid comp set to feel confident in a valuation.
- Sellers expecting a fast close on a compressed timeline.
- Buyers working from a fixed budget well below the current median price tier here.

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.
Reading a thin data set correctly
With only four closings feeding the current window, the median price and the year-over-year comparison are both sensitive to the specific homes that happened to sell. A $4,675,000 median and a $1,145.79 price per square foot describe this segment's general price tier, but they are not a substitute for looking at the actual comparable sales one by one — condition, finish level, and lot specifics will explain more of the variance than the aggregate figures can.
The median 132.5-day marketing period is the more dependable indicator in a small sample, and it points to a market where pricing discipline matters. Homes that are priced to the moment tend to transact; homes priced against last year's comps, or against a headline appreciation number, tend to add days on market rather than close faster.
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.
Why work with Momentum here
In a market this thin, the comps require interpretation, not just a lookup. We walk buyers and sellers through the individual closed sales behind the median — not just the aggregate number — so pricing decisions are grounded in what actually sold, not in a statistic built on four data points.
