Listing description

About this home

Superior construction, exceptional craftsmanship, and thoughtful design define this 2020 built custom waterfront residence. Located in the coveted Causeway Isles neighborhood, the home was built to exceed standards with solid concrete block construction, hurricane-rated impact windows and doors, metal roof, and Icynene spray-foam insulation—offering durability, efficiency, and long-term peace of mind. As a fully integrated smart home, Alexa-enabled controls enhance comfort, convenience, and energy performance throughout.

The entry begins with oversized 16-foot doors, opening to a light-filled foyer anchored by a striking floating staircase. The main living level unfolds upstairs into an expansive open-concept layout with 22-foot vaulted ceilings, wide-plank oak flooring, and sweeping water views. The kitchen is a coastal statement with two-tone cabinetry, quartz surfaces, premium stainless appliances, and an oversized island centered around a farmhouse sink.

The primary suite offers a serene escape, complete with water views, 10 foot ceilings, electric blackout blinds, and an enormous walk-in closet. The spa-style bath rivals a five-star resort, featuring dual quartz vanities, a large glass-enclosed shower, and a deep soaking tub. A thoughtfully designed split-bedroom layout ensures privacy and comfort for guests.

The exterior is finished with stunning Tabby Shell stucco, slip-resistant pavers, a resort-style pool, covered outdoor kitchen, and ample space for entertaining. Enjoy unforgettable Treasure Island sunsets from the upper-level balcony. Boaters will appreciate the exceptional dock setup, with a 16,000-lb lift, deep protected water, Trex decking, and quick access to Boca Ciega Bay and the Gulf of Mexico.

The six-car garage has tons of space for storage and work areas.

The Messtimate™

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.

$1,257,707the mess$1,603,377

Actual list price: $2,550,000 — 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 renovated kitchen or new roof vs. dated finishes can swing value six figures; sq ft can't see it.
  • 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.
  • The pool — a private pool carries cost and value that living area doesn't capture.

And here's what the live market is doing — which the number above ignores entirely:

  • 3 active listings competing, 2 under contract
  • 3.2 months of supply
  • 15 closed here in the last 12 months

For reference, this home is listed at $2,550,000 ($959/sq ft) — a number set with analysis a Messtimate can't do.

Before you decide

Buyer research checklist

Items worth confirming for 7966 1St Avenue, chosen from what the record shows. This is general guidance, not advice about this specific property.

  • Built in 2021: confirm the roof and HVAC install dates and whether any builder or manufacturer warranty transfers.
  • The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
  • 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.
  • Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
  • Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
  • Listed living area is 2,659 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 $26,775/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.

Frequently asked questions

How big is 7966 1St Avenue and when was it built?

Per the listing record, 7966 1St Avenue was built in 2021 and has 2,659 sq ft of living area, 4 bedrooms and 2.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.

What community is 7966 1St Avenue in?

7966 1St Avenue is in South Cswy Isle 2Nd Add in St Petersburg, Pinellas County. The community section on this page shows recent closed sales, days on market, and active inventory for South Cswy Isle 2Nd Add from the same MLS data.

Does 7966 1St Avenue have an HOA?

The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.

Why might property taxes on 7966 1St Avenue differ from the current owner's?

The estimate on this page (about $26,775 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 7966 1St Avenue 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.
