GRAND BAY RESIDENCES COND
Homes for Sale in Key Biscayne, FL

GRAND BAY RESIDENCES COND market snapshot (as of July 20, 2026): the median sale price is about $2.73M ($932 per sq ft over the trailing 12 months of closed sales), and a median 47 days on market for closed sales.

Grand Bay Residences sits at the high end of the Miami-Dade condo market, with pricing and per-square-foot values that reflect a small, closely watched pool of listings rather than high-volume turnover.

A median price of $2,730,000 against a median per-square-foot figure near $932 tells you this is a market where unit size, layout, and orientation drive value more than any single blanket price tag. Two units at the same square footage can land in very different places depending on renovation state and view.

The 47-day median days-on-market, paired with a closings count of just three in this window, means every transaction here is effectively its own data point. That is normal for a building at this price level, but it also means sellers should not expect the kind of rapid, comp-driven pricing pressure you would see in a high-volume segment — and buyers should not assume urgency where none exists. Current MLS listings do not identify specific community amenities, so any building-specific features should be confirmed directly rather than assumed from market data.

In a market this thin — three closings in the window — the comps you use to set or negotiate a price matter more than usual. We work from the actual transaction data for this building, not broad neighborhood averages, and we tell clients directly when the sample size means a number needs to be treated as a range, not a guarantee.

Confirm the current HOA dues, exactly what they cover, and any CDD bond or special assessment for a specific address before you offer.
