Building permits
Comparable recent sales
6 closed sales in TREASURE ISLAND TENNIS & YACHT CLUB in the last 18 months — same property type, living area within 30% of this home. Sold prices are MLS closed-sale records, deemed reliable but not guaranteed.
Median of these 6 sales: $312,500 ($290/sq ft). Stronger local evidence. Shown for general reference only — not an appraisal or a statement of this home’s value.
The Messtimate
This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
Stronger local evidence — 6 comparable closed sales in TREASURE ISLAND TENNIS & YACHT CLUB, closed within the last 18 months, same property type, living area within 30% of this home.
Actual list price: $342,500 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 54% spread on the same house — and that gap is exactly what an automated guess can't see:
- Condition & updates — a 1974 home may have had its roof, kitchen, or HVAC replaced since, or not; sq ft can't see either.
- The lot & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
- Outliers skew it — the band above comes from 6 nearby sales; one flip or distressed sale moves the whole $/sq ft.
- Carrying costs & concessions — this home carries HOA dues of $1,152/mo; with insurance and any seller-paid buydown, that changes what a buyer actually pays, and a sq ft estimate ignores all of it.
And here's what the live market is doing — which the number above ignores entirely:
- This home: 134 days on market vs. a 168-day community median
- 9 active listings competing, 1 under contract
- ≈24.0 months of supply
- 5 closed here in the last 12 months
For reference, this home is listed at $342,500 ($262/sq ft). The list price is the seller's asking price and is not derived from this range.

Buyer research checklist
Items worth confirming for 450 Treasure Island Causeway #104, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1974 (52 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
- Condominium: request the association's budget, reserves, the most recent milestone or structural inspection report, and two years of meeting minutes before relying on the dues.
- FEMA flood zone AE: lenders generally require flood insurance here — get an elevation certificate and a flood quote before the inspection period ends.
- Get a homeowners insurance quote for this specific address in Pinellas County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Listed living area is 1,308 sq ft: verify it against the property appraiser's record and measure before relying on it.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $3,596/yr) assumes reassessment at the list price; the seller's current bill is not a guide Exemptions and portability change the actual bill — confirm with the county property appraiser.
- School zoning shown here comes from district data and changes; confirm the assigned schools directly with the district before relying on them.

Frequently asked questions
How big is 450 Treasure Island Causeway #104 and when was it built?
Per the listing record, 450 Treasure Island Causeway #104 was built in 1974 and has 1,308 sq ft of living area, 2 bedrooms and 2.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 450 Treasure Island Causeway #104 in?
450 Treasure Island Causeway #104 is in Treasure Island Tennis & Yacht Club in Treasure Island, Pinellas County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 450 Treasure Island Causeway #104 have an HOA, and how much are the dues?
The listing reports HOA dues of $1,152 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
Why might property taxes on 450 Treasure Island Causeway #104 differ from the current owner's?
The estimate on this page (about $3,596 per year) assumes reassessment at the list price less the homestead exemption. Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 450 Treasure Island Causeway #104 in a flood zone?
The FEMA flood map places this parcel in Zone AE, a special flood hazard area where lenders generally require flood insurance on a mortgaged purchase. Confirm the parcel's status with FEMA and your insurer, and ask for an elevation certificate.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
