Mariner Apts Marco Island
Homes for Sale in Marco Island, FL

Mariner Apts Marco Island market snapshot (as of July 29, 2026): the median sale price is about $390K ($479 per sq ft over the trailing 12 months of closed sales), and a median 36 days on market for closed sales. The trailing-12-month median is down 10% from the prior 12 months, computed from record-level fgc closed sales (5 closings in the current window).

Mariner Apts is a Marco Island condominium community where pricing runs on unit condition and square footage rather than shared amenities, with a small, low-volume resale market that moves at a measured pace.

With only five closings feeding the current snapshot, Mariner Apts is a thin market by definition — enough to establish a median price and a pace, not enough to draw firm conclusions about direction. The 10.5% year-over-year decline is worth watching over the next several closings rather than treated as an established trend; a small sample can move a lot on one or two atypical sales.

The 36-day median days-on-market and heat score of 46 both describe a market that isn't under pressure in either direction — not a rush of competing offers, not a standoff either. That gives both sides room to negotiate on price and terms rather than react to a clock. With no amenities identified from current listings, buyers should expect the value proposition here to rest on the unit's condition, layout, and per-square-foot economics rather than on building perks.

In a low-volume market like Mariner Apts, every closing carries outsized weight in the data, which means pricing a listing or evaluating an offer requires looking past the headline median to the specific comparable units and their condition. We track that detail closely so sellers price accurately and buyers don't overpay based on a thin sample.
