What it really costs to own 3718 Harborside Avenue
The parts of the monthly number a mortgage calculator leaves out, from this listing's MLS record, the county tax roll, Citizens and FEMA. Property facts only.
Property tax
The current owner's bill is $2,146/yr per the MLS listing record (TaxAnnualAmount, 2026-10-13). Florida reassesses at sale, so a buyer's first bill is usually higher than the seller's; the county millage here is not verified, so no reset figure is printed.
HOA dues
$278/month per the listing record. Dues cover what the association documents say they cover; ask for the budget and reserve study before you close.
Home and flood insurance
The average Citizens Property Insurance premium in Saint Lucie County is $2,332/yr (2,890 policies, Citizens detail by county, April 2026); private-market quotes differ by roof age, wind mitigation and distance to the coast. The page's modeled range for this home is $500–$1,500/yr; neither is a quote.
Roof and age
Built in 2026. A newer roof and current wind-mitigation features usually mean the lower end of insurance quotes; ask for the wind-mitigation form.
Estimated carrying cost at the asking price, before the mortgage: about $651/month (tax $179, HOA $278, insurance $194). An estimate from the sources above, not a quote; the monthly-cost calculator on this page adds the loan.
Estimated ownership costs
Estimated costs & disclosures
Estimated ownership costs for general information. Confirm each with the county, your lender, and an insurer. See data & estimate notes.
Property tax (first-year est.)
~$3,149/yr
Estimate: a typical St. Lucie effective rate applied to the list price before any exemptions. Florida bills change with reassessment, homestead and other exemptions, and local taxing districts — this is not your expected bill. Confirm with the county property appraiser.
CDD assessment
None on record
No CDD assessment appears in our records for this community. CDD assessments show on the county tax bill — confirm with the tax collector.
Insurance (illustrative range)
$500–$2k/yr
An illustrative modeled range, not based on carrier underwriting and not a quote. Florida premiums vary significantly by roof age, wind-mitigation features, claims history, and carrier — a real quote can land well outside this range. Flood zone not verified for this address — check msc.fema.gov and confirm coverage. Get a quote from a licensed insurer before relying on any figure.

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.
$281,456the mess$307,304
Directional estimate — 6 comparable closed sales within about 10 miles in St. Lucie County, closed within the last 18 months, same property type, living area within 30% of this home.
Actual list price: $299,900 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 9% spread on the same house — and that gap is exactly what an automated guess can't see:
Condition & finishes — as new construction, builder upgrades and finish level aren't in a sq ft number.
The lot — this listing is waterfront; water frontage is priced far off a per-sq-ft average of the neighborhood.
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 $278/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: 46 days on market vs. a 20-day community median
5 active listings competing
≈12.0 months of supply
2 closed here in the last 12 months
For reference, this home is listed at $299,900 ($209/sq ft). The list price is the seller's asking price and is not derived from this range.

Oct 2026 · Development
Port St. Lucie board considers rezoning for up to 1,200 homes at Wilson Grove
The Planning and Zoning Board took up a rezoning of nearly 360 acres of agricultural land north of SW Becker Road, between SW Sundance Vista Boulevard and Rangeline Road, to a master planned unit development. The concept plan allows up to 1,200 homes plus parks, lakes and clubhouses. City Council would vote later in October.
Why it matters: Up to 1,200 new homes in western Port St. Lucie would add housing supply and increase traffic demand on Becker Road. The project is about 24 miles south of Seagrove Pud, elsewhere in St. Lucie County.
Buc-ee's at I-95 and Indrio Road finishes county planning, awaits state approvals
The planned travel center would be about 76,000 square feet with roughly 120 fuel pumps at Interstate 95 and Indrio Road near Fort Pierce. County planning is complete, but FDOT and DEP approvals are still needed. Nearby proposals include Indrio Town Center on about 85 acres and Indrio Groves with more than 3,000 homes.
Why it matters: A large travel center would add retail and fuel access at the I-95 interchange and draw further development interest along Indrio Road. The site is about 8 miles south of Seagrove Pud.
Indian River County weighs proposed third hospital near State Road 60 and 66th Avenue
Commissioners discussed a proposed hospital of about 250,000 square feet and five stories on a 75-acre holding near State Road 60 and 66th Avenue in Vero Beach. Current limits are 35 feet and 60,000 square feet, so a special exemption and comprehensive plan changes would be needed. No approval has been given, and the board planned to revisit it October 6.
Why it matters: A western hospital campus would add healthcare capacity and could shorten emergency response times for western Vero Beach, if approved. The site is about 8 miles west of Seagrove Pud.
St. Lucie County reviews updated Port of Fort Pierce master plan with mega-yacht marina and spaceport recovery facility
The 2026 master plan for the Port of Fort Pierce proposes a mega-yacht marina, a spaceport recovery facility, expanded boat ramps and restaurants, with a marine commercial district at Harbour Pointe. County officials say nearly 15,000 registered boats compete for 147 trailer parking spaces near the inlet. The plan is under county review and Fort Pierce holds final approval.
Why it matters: Added boat ramp parking and marine commercial space would expand waterfront access and dining options near the Fort Pierce Inlet over a multi-year timeline. The project is about 10 miles south of Seagrove Pud, elsewhere in St. Lucie County.

Frequently asked questions
How big is 3718 Harborside Avenue and when was it built?
Per the listing record, 3718 Harborside Avenue was built in 2026 and has 1,436 sq ft of living area, 3 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 3718 Harborside Avenue in?
3718 Harborside Avenue is in Seagrove Pud in Fort Pierce, St. Lucie County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 3718 Harborside Avenue have an HOA, and how much are the dues?
The listing reports HOA dues of $278 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 3718 Harborside Avenue differ from the current owner's?
The estimate on this page (about $3,149 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 3718 Harborside Avenue in a flood zone?
A flood designation has not been verified for this address. Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) and confirm with 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.
