Mansions By The Sea Condo
Homes for Sale in Treasure Island, FL
True comps, carrying-cost math, and listings before the portals.

Mansions By The Sea is a 173-unit condo community in Treasure Island, built out over a tight window from 1980 to 1987. With a median living area around 1,140 square feet and a median build year of 1984, this is a mature coastal building where price is driven far more by unit condition, floor, exposure, and view than by square footage — the footprints don't vary much, so what separates one closing from the next is the interior and the outlook.
The transaction pace has been thin recently, with only a couple of closings in the current window. That means individual sales carry outsized weight, and both sides should treat any single comp with caution. For a seller, condition and presentation are the levers you control; for a buyer, it's a market where patience and a willingness to underwrite the specific unit — not the building average — pays off.
Who Mansions By The Sea Condo is best for.
Best for
- Buyers seeking a coastal condo as a seasonal or investment holding who will scrutinize HOA finances
- Buyers who value an updated interior and a good view over raw square footage
- Buyers comfortable with a thin comp set and willing to underwrite a specific unit
Probably not for
- Buyers who need a large floor plan or newer construction
- Buyers who want a deep pool of recent comparable sales to anchor an offer
- Buyers seeking low, highly predictable carrying costs in an older coastal building

The Mansions By The Sea Condo buying strategy.
If we were buying in Mansions By The Sea 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 Mansions By The Sea Condo.
A condition-driven condo market
With units built between 1980 and 1987 and a median living area near 1,140 square feet, Mansions By The Sea offers a consistent product type rather than a wide range of floor plans. That consistency cuts both ways: it's easy to compare like against like, but it also means updates, views, and floor placement do the heavy lifting on value. Buyers should expect a wide spread between renovated and original units even within a narrow size band.
The homestead share here sits under 20%, which tells you a large majority of units are not owner-occupied primary residences — consistent with a coastal condo used seasonally or as an investment. Anyone buying should read the association's documents closely: reserves, insurance, and any assessment history matter enormously in a building of this vintage, and they belong at the center of your due diligence.
The location and the amenities are priced into every listing in Mansions By The Sea Condo. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a building where recent closings are few and value hinges on the specific unit, generic pricing guidance falls apart. We underwrite each unit on its own merits — condition, floor, exposure — and we push on the association financials and insurance posture that make or break a 1980s coastal condo, so you go in with eyes open on both price and carrying costs.
