Property taxes
✓ Based on certified county tax rollMany first-time Florida buyers are surprised when property taxes jump after closing. This estimate helps you budget before you make an offer.
Most of this comes from Florida’s Save Our Homes assessment cap resetting when the home sells — the current owner’s protected assessment doesn’t transfer to a new buyer.

Data is deemed reliable but is not guaranteed by the MLS to be accurate.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.
Actual list price: $449,500 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 27% spread on the same house — and that gap is exactly what an automated guess can't see:
- Condition & updates — a 1969 home may have had its roof, kitchen, or HVAC replaced since, or not; sq ft can't see either.
- The lot — this listing is waterfront; water frontage is priced far off a per-sq-ft average of the neighborhood.
- Outliers skew it — one flip or distressed sale in the comps drags the whole $/sq ft up or down.
- Carrying costs & concessions — CDD, HOA, insurance, and seller-paid buydowns change what a buyer actually pays.
And here's what the live market is doing — which the number above ignores entirely:
- This home: 4 days on market vs. a 45-day community median
- 4248 active listings competing, 1595 under contract
For reference, this home is listed at $449,500 ($484/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 1300 N Portofino Drive #103, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1969 (57 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 Sarasota County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
- Listed living area is 929 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 $4,720/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
- Confirm school zoning directly with the district.

What community is 1300 N Portofino Drive #103 in?
1300 N Portofino Drive #103 is in Siesta Harbor Ii in Sarasota, Sarasota County. The community section on this page shows recent closed sales, days on market, and active inventory for Siesta Harbor Ii from the same MLS data.
Why might property taxes on 1300 N Portofino Drive #103 differ from the current owner's?
The estimate on this page (about $4,720 per year) assumes reassessment at the list price. Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment resets after a sale, so a new owner's bill may differ from the seller's. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 1300 N Portofino Drive #103 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.
