As of September 2026, Grand Bay Residences Cond in FL has 2 homes for sale. As of September 2026, the MLS records 36 closed sales in Grand Bay Residences Cond in FL since 2018, the most recent in February 2026. Recorded prices since 2024 ran from $2,662,500 to $4,500,000 (median $2,750,000), on homes of 2,570 to 3,660 sq ft. At that median and Miami-Dade County's FY2025-26 rate of 17.59 mills, annual property tax runs about $48,380 ($47,670 with the full homestead exemption).
Grand Bay Residences trades at a median price of $2,730,000 with a median of $932.20 per square foot, pricing that puts it firmly in the upper tier of Miami-Dade condo product. At this price point, the per-square-foot figure is doing most of the talking — buyers here are paying for finish level, floor plan, and view corridor as much as raw square footage.
With only three closings in the current window, this is a thin-trading market by definition, and the 47-day median days-on-market should be read as a signal of a deliberate, negotiated process rather than a fast-moving list-and-sell environment. Pricing a unit here takes a comparable-by-comparable approach, not a formula.
The 60-Second Overview
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.

Who Grand Bay Residences Cond is best for.
Best for
- Buyers with a budget aligned to a median near $2.73M who are focused on unit-level detail over neighborhood-wide averages
- Buyers comfortable with a longer, negotiated process reflected in a 47-day median days-on-market
- Buyers who want per-square-foot pricing data — near $932 — as a starting point for their own unit-specific evaluation
Probably not for
- Buyers expecting a large active inventory to compare against, given only three closings in this window
- Buyers who need documented building amenities before making an offer, since current MLS listings do not identify them
- Buyers looking for a fast-turnaround flip market rather than a deliberate, comp-by-comp purchase

The Grand Bay Residences Cond buying strategy.
If we were buying in Grand Bay Residences Cond 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 Grand Bay Residences Cond.
What the numbers actually say
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.
The location and the amenities are priced into every listing in Grand Bay Residences Cond. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
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.
