Property taxes in Florida are reassessed after a sale, so a buyer’s first full-year bill can be higher than the seller’s. Budget from this estimate, not the current bill, 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 does not transfer to a new buyer.

| Property tax | The current owner's bill is about $18,950/yr (certified county roll, taxable value × millage). Buy at the asking price of $2,600,000 and the first-year bill resets to about $39,450/yr (the parcel is matched to the certified roll; asking price less the $50,000 homestead exemption × 15.47 mills (county-average millage, estimate)); Save Our Homes caps later increases at 3%/yr. |

| HOA dues | $230/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 Martin County is $2,580/yr (1,552 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 $9,000–$18,500/yr; neither is a quote. Flood: this address maps to FEMA zone X, outside the high-risk zone; flood insurance is optional but most lenders and insurers recommend it. Statewide, a zone X flood policy runs about $500–$700/yr (FEMA Risk Rating 2.0 averages, not a quote). |
| Roof and age | Built in 2005. An original roof would be about 21 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report and ask for the roof permit date. |
Estimated carrying cost at the asking price, before the mortgage: about $3,732/month (tax $3,288, HOA $230, insurance $215). An estimate from the sources above, not a quote; the monthly-cost calculator on this page adds the loan.

Mattamy is moving 125 acres from the northern part of its Newfield development to Martin County for river restoration, matched by an adjacent 125 acres from the Florida Inland Navigation District. The combined land can hold about 2.4 million cubic yards of dredged muck, and removal starts only after federal funding is authorized.
Why it matters: Preserves open land near Newfield and supports St. Lucie River water quality, with possible recreational use of the parcels later. The project is about 6 miles southwest of Lost River Cove, elsewhere in Martin County.
Commissioners voted 4-0 on Oct. 27 for a one-year pause on data center development. A hyperscale application west of I-95 off Kanner Highway was filed earlier and is not affected.
Why it matters: Sets a pause on a large industrial land use while the county writes rules, which shapes what may be built near western Martin corridors. The site is about 7 miles southwest of Lost River Cove.
Commissioners voted to end the contract with Martin County Transit and negotiate a one-year emergency agreement with MTM Transit after service stopped suddenly the prior week. County staff hoped to restart service within about a week.

Per the listing record, 665 SW Yacht Basin Way was built in 2005 and has 3,944 sq ft of living area, 5 bedrooms and 4.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
665 SW Yacht Basin Way is in Lost River Cove in Stuart, Martin County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
The listing reports HOA dues of $230 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
The estimate on this page (about $39,450 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $20,500 more per year than the current owner’s estimated bill (+108%). 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.
The FEMA flood map places this parcel in Zone X, outside the special flood hazard area, so flood insurance is not usually required by a lender. It is still available and worth quoting; confirm the parcel's status with FEMA and your insurer.
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.
