Grand Bay Tower Condo has produced very little in the way of recent closed activity, with only a single closing in the current window. That kind of thin transaction volume means there is not enough data to establish a reliable price trend, and any pricing conversation here has to lean on comparable buildings and unit-specific condition rather than a statistically meaningful average.
For a buyer or seller, the practical takeaway is that this is a market where you negotiate off the individual unit, not off a headline number. A single closing does not tell you whether the building is tightening or loosening, so due diligence on recent comparable sales in the immediate area matters more than usual.
The 60-Second Overview
Grand Bay Tower Condo sits in Miami-Dade County, and current MLS data does not identify specific building amenities, so anything beyond the unit itself should be confirmed directly with the condo association.
MIAMI REALTORS sales records identify 14 homes in GRAND BAY TOWER Condo that have changed hands since 2016, built between 1998 and 1999 (median 1999), with a median living area of about 2,930 sq ft and a typical 3-bedroom, 4-bath layout; 100% are condominiums.

Who Grand Bay Tower Condo is best for.
Best for
- A buyer comfortable making a decision based on unit-specific inspection and building due diligence rather than a market track record
- A buyer or seller open to a longer, more hands-on negotiation given limited comparable sales
- Someone prioritizing a Miami-Dade condo location over amenity-driven decision making
Probably not for
- A buyer who wants a clear, data-backed price trend before committing
- Someone relying on specific building amenities as a primary decision factor without confirming them first
- A buyer uncomfortable proceeding without several recent comparable closings to reference

The Grand Bay Tower Condo buying strategy.
If we were buying in Grand Bay Tower Condo 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 Tower Condo.
Reading a Thin Data Market
With only one closing in the current window, Grand Bay Tower Condo does not offer the kind of sample size that supports confident pricing benchmarks. This is common in smaller or slower-turning condo buildings, and it means both buyers and sellers should treat any single comparable sale as a data point rather than a market signal.
Because current MLS listings do not identify community amenities, prospective buyers should request building-specific details directly from the association or a current listing agent, covering things like building services, parking arrangements, and any assessments, none of which can be assumed from market data alone.
The location and the amenities are priced into every listing in Grand Bay Tower Condo. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a building with this little recent transaction history, the value of an agent who will actually verify unit-level condition, building financials, and true comparables outweighs any reliance on a headline market statistic. We do that legwork before you make an offer, not after.

What it really costs to own in Grand Bay TowerCondos for Sale
The parts of the monthly number a mortgage calculator leaves out, from the tax roll, the MLS, Citizens and FEMA. Property facts only.
| Property tax | Current owners' bills run a median of $34,752/yr across 5 listings here (MLS tax records, 2026-10-16). |
|---|---|
| HOA dues | Median $3,370/month across 76 MLS listings (most billed monthly; 2026-10-15). Dues cover what the documents say they cover; ask for the budget and reserve study. |
| Home and flood insurance | The average Citizens Property Insurance premium in Miami-Dade County is $1,891/yr (56,357 policies, Citizens detail by county, April 2026); private-market quotes depend on roof age, wind mitigation and construction. |
| Roof and age | Median build year 1999 across 5 listings. An original roof here would be about 27 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report, and for replacement where it fails. |
Estimated carrying cost at the median asking price, before the mortgage: about $6,424/month (tax $2,896, HOA $3,370, insurance $158). An estimate from the sources above, not a quote.
