Martin County new construction communities at a glance

The communities, by recent sales activity

Communities are listed by recent closing volume in Momentum’s MLS data. Figures are aggregates, change over time, and are deemed reliable but not guaranteed.

Buying new construction without leaving money on the table

Builders in these communities are competing on incentives — rate buydowns, closing-cost credits, and price adjustments. The right comparison is never sticker price: a $20,000 rate buydown and a $20,000 price cut produce different monthly payments. Run the actual trade with our builder incentive calculator before you sign.

The two costs new-construction buyers miss

First, property taxes: year one is often billed on the unimproved lot, then the assessment resets to your purchase price — model the real year-two bill with the property tax after purchase calculator. Second, CDD bonds: many new communities carry a community development district assessment on the tax bill for decades. Ask for the CDD annual amount and remaining term in writing, and always use your own inspector at the pre-drywall and final stages — builder warranties are not a substitute.

What it costs to own here

At Martin County’s typical combined millage of 15.47 mills, a purchase at $533,000 (the median across these new construction communities) generates roughly $8,245 a year in property tax before exemptions — about $687 a month. Florida resets the assessed value to roughly your purchase price, so the seller’s current bill is not a preview of yours; a homesteaded owner then gets the $25,000–$50,000 exemption and the 3% Save Our Homes cap going forward. Citizens Property Insurance policies in Martin County average about $2,580 a year ($215 a month) — private-market quotes vary with roof age and wind mitigation, so price coverage before your inspection window closes. All-in, our county model puts the typical monthly cost of ownership in Martin County near $2,754 (principal and interest on the typical home, tax, and insurance).

Run your exact numbers: the property tax after purchase calculator uses Martin County’s verified millage, and the buyer closing costs calculator builds the full cash-to-close.

The Martin County market, in context

Martin County is Stuart and the Sailfish-Capital coast — a deliberately low-density, affluent Treasure Coast county that has fought to preserve its small-town, waterfront character.

The economy behind the market: {'drivers': 'healthcare, marine industry, professional services, and agriculture', 'summary': "Martin's economy is anchored by Cleveland Clinic Martin Health (the county's largest employer), a robust marine industry — boat building, repair, and yacht services around Stuart's waterways — plus professional services tied to an affluent population and an agricultural base (citrus, cattle) in the west. The county's strict growth management deliberately limits the scale of development.", 'employers': ['Cleveland Clinic Martin Health', 'Martin County School District', 'Martin County government', 'marine-industry firms (boatbuilding, repair, yacht services)', 'Publix', 'agriculture (west county)'], 'jobNote': "Cleveland Clinic Martin Health is the county's largest employer; Stuart's marine industry — boatbuilding, repair, and yacht services — is a defining sector."}

What could change it: Martin carries Treasure Coast hurricane and storm-surge exposure on the barrier island and along the rivers, with high coastal insurance, and the Indian River Lagoon's health is an environmental concern. The county's strict growth management keeps supply tight (supporting values but limiting options), and prices run above the neighboring Treasure Coast counties.
