Costain Villas Harbor Vil is pricing around a median of $475,000, with per-square-foot value near $350.81. That per-foot figure does a lot of the talking here — it suggests value is tied closely to condition and layout rather than a uniform build style, so two listings a few doors apart can price very differently depending on updates.
The year-over-year read of -10.8% and a median of 61 days on market point to a market that has softened and is taking longer to clear. That combination favors buyers willing to negotiate on price or terms, and it means sellers need to price close to recent comparables rather than anchor to last year's numbers. With only 3 closings in the current window, any single sale can move the median, so treat these figures as a directional read, not a precise valuation.

Who Costain Villas Harbor Vil is best for.
Best for
- A buyer who wants to evaluate each available unit on its own condition and pricing rather than relying on a broad market trend.
- A buyer with flexible timing who can wait through a longer-than-average days-on-market cycle to find the right unit.
- A buyer prepared to negotiate given the recent year-over-year softening in pricing.
Probably not for
- A buyer who wants a large set of active listings to compare before making a decision.
- A buyer expecting a fast-moving market with quick offer-to-close timelines.
- A buyer who wants pricing certainty from a high-volume sales history rather than a handful of recent closings.
Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending September 20 of each year, from record-level MIAMI MLS closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($475K) IS the median in the snapshot above, and the move from 2025 ($510K) IS the -6.9% one-year change.
Windows contain 1 to 5 sales each (4 in the current window); every figure carries its sample size, and thin markets swing on single closings.

The Costain Villas Harbor Vil buying strategy.
If we were buying in Costain Villas Harbor Vil 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 Costain Villas Harbor Vil.
Reading a Thin Market
With just 3 closings feeding the current snapshot, Costain Villas Harbor Vil doesn't behave like a high-volume tract where pricing patterns smooth out over dozens of sales. Each transaction here is a meaningful data point, and that means the median price and per-square-foot figure should be read as a snapshot of what closed recently, not a fixed benchmark for every unit in the community.
The median days on market at 61 signals homes are sitting longer than a fast-moving segment would tolerate, and the year-over-year decline of -10.8% reinforces that this is a market in a cooling phase rather than an accelerating one. Buyers have more room to negotiate on price and timeline; sellers who want to move on a normal schedule should expect to price tightly to what has actually closed, not to what similar units fetched a year ago.
The location and the amenities are priced into every listing in Costain Villas Harbor Vil. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a low-volume segment like this, the difference between a good outcome and a mediocre one often comes down to reading the last few closings correctly — not guessing at a trend line. We pull the actual comparable sales, price per square foot, and days-on-market data before advising on offer strategy or list price, so you're negotiating from what has really happened here recently, not from a stale average.
