Tropical Isle Homes Sub 4 trades in a narrow, high-value tier of the Miami-Dade market where pricing is driven almost entirely by the individual property rather than by any shared community feature.

Eleven closings is not a statistically deep sample, and that matters for how you read every figure in this snapshot. The $1,729.91 median price per square foot is a useful benchmark for gauging whether a given listing is priced in line with recent activity, but with volume this low it should be treated as a directional signal, not a fixed ceiling or floor.

The 69-day median days-on-market suggests transactions here go through a fuller vetting process than a fast-turn market would — consistent with the price band, where financing, inspection, and negotiation windows tend to run longer regardless of how much demand exists. A 58.2% year-over-year increase alongside a heat score of 66 tells you buyers are active and competitive, but the extended DOM figure is a reminder that competitive does not mean rushed.

In a market this thin, comparable-sale analysis has to be done property by property rather than by trend line alone. Momentum tracks each closing in this subdivision as it happens, so pricing conversations — on either side of the table — are grounded in what has actually sold, not in a lagging or overly broad median.
