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.
$1,149,240the mess$1,299,960
Actual list price: $1,170,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 13% 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 & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
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:
4 active listings competing
≈3.7 months of supply
12 closed here in the last 12 months
For reference, this home is listed at $1,170,000 ($373/sq ft) — a number set with analysis a Messtimate can't do.

The Berkeley Palm Beach Breaks Ground at 550 South Australian Avenue in West Palm Beach
The Berkeley Palm Beach broke ground on a 25-story tower with 193 condominium residences at 550 South Australian Avenue overlooking Clear Lake, developed by Al Adelson with Arquitectonica as designer. Sales have exceeded $120 million and completion is anticipated in 2029.
Why it matters: A new 25-story condominium tower adds high-end for-sale housing supply to the downtown West Palm Beach market and continues vertical development along the Clear Lake waterfront. The project is about 10 miles northeast of Castellina, elsewhere in Palm Beach County.

Terra and BH Group filed plans for 281 residential condominiums across two 31-story towers on a 1.55-acre site at 2085 N Flagler Drive in West Palm Beach. The nearly 440,000-square-foot project includes about 4,385 square feet of retail and 362 parking spaces.
Why it matters: Two proposed 31-story towers would add for-sale condominium supply and ground-floor retail along the North Flagler Drive waterfront in West Palm Beach. The project is about 12 miles northeast of Castellina, elsewhere in Palm Beach County.

Congress Avenue, backed by a $92 million construction loan from Madison Realty Capital. The plan includes 154 workforce housing units under Florida's Live Local Act and 232 market-rate units, with delivery expected in late 2027.
Why it matters: A 386-unit rental community converts a former industrial parcel into new multifamily supply on the Congress Avenue corridor and adds workforce and market-rate housing to the Delray Beach market. The project is about 15 miles southeast of Castellina, elsewhere in Palm Beach County.

Answered before you ask
Frequently asked questions
Why might my property taxes differ from the current owner's?
Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment can be re-set after a sale. As a result 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.
Where does the flood-zone information come from?
The flood designation shown (Zone X) comes from the FEMA flood map and is provided for general information. Confirm the parcel's status with FEMA and your insurer.
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.
