The builders, ranked by recorded closings

Methodology: closings and actives are counted from listings recorded by builder-affiliated sales offices in contributing MLS feeds, build year 2024 or newer, as of 2026-06-16. Builders who sell primarily outside the MLS may be undercounted, and volume is not an endorsement of build quality. Deemed reliable but not guaranteed.

Volume tells you who is active. It does not tell you who to hire.

A builder’s closing count tells you they can deliver homes in this county at scale — supply chains, trades and permitting all working. It does not tell you how they handle warranty claims, change orders, or a framing defect found at the pre-drywall walk. Before you sign: read the builder’s contract (it is not the standard Florida resale contract, and it is written by the builder’s attorneys), hire your own inspector for pre-drywall and final walks, and ask for addresses of homes delivered 12+ months ago so you can ask owners how service after closing actually went.

Negotiating with builders in Martin County

Builders protect base prices and negotiate with incentives instead: rate buydowns, closing-cost credits, design-center credits, or lot premium waivers. A $20,000 buydown and a $20,000 price cut are not the same deal — compare them properly with our builder incentive calculator. Then model the year-two tax bill (new construction is often taxed on the lot in year one, then reset to your purchase price) with the property tax after purchase calculator, and ask for the CDD assessment and remaining bond term in writing. An agent costs you nothing on a new build — the builder pays the commission — and an agent who has closed with these builders knows which incentives each will actually move on.

What it costs to own here

At Martin County’s typical combined millage of 15.47 mills, a purchase at $534,490 (the median recorded builder price) generates roughly $8,268 a year in property tax before exemptions — about $689 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.
