Treasure Coast Land: Buying Acreage in Martin, St. Lucie & Indian River

The Treasure Coast is best known for its beaches, but drive a few miles inland and it turns into citrus groves, cattle pasture, and open acreage. Martin, St. Lucie, and Indian River counties pair coastal living with a deep agricultural interior, and for land buyers that inland country is some of the most appealing in the region.

Here's how the three Treasure Coast counties compare for rural and acreage land.

Key Takeaways

• Port St. Lucie is one of the nation's fastest-growing cities, reaching about 268,000 residents in 2025 (U.S. Census Bureau).
• Martin County caps buildings at four stories and uses a 1982 urban-services boundary to protect rural land (Martin County).
• Indian River County is famous citrus country, ranking second in Florida for grapefruit (Indian River County ED).
• Inland acreage across all three can qualify for Florida's Greenbelt agricultural tax classification (Fla. Stat. 193.461).

St. Lucie County: growth and value

St. Lucie is the Treasure Coast's growth engine. Port St. Lucie added more than 9,000 residents in a single year to reach about 268,000 in 2025, and its metro ranked among the nation's fastest-growing (U.S. Census Bureau). That momentum, anchored by Fort Pierce as the county seat, keeps demand for both homesites and investment land strong. West of the cities, St. Lucie opens into ranch and grove country where acreage trades well below the coast. Browse St. Lucie County land.

Martin County: low density by design

Martin County has worked hard to stay rural. A countywide four-story building height limit and an urban-services boundary dating to 1982 have curbed sprawl and preserved open land and agriculture (Martin County). The county farms more than 150,000 acres across roughly 594 farms, from citrus and cattle to sugarcane (UF/IFAS). Stuart anchors the coast, while Indiantown to the west is the county's agricultural and ranching hub. For buyers who value protected rural character, Martin is hard to match. See Martin County land.

Indian River County: citrus country

Indian River County is synonymous with citrus. The Indian River growing region is internationally known, and the county ranks second in Florida for grapefruit and among the state's top citrus producers (Indian River County Economic Development). Vero Beach anchors the coast, while Fellsmere and the western county hold the agricultural land, much of it reclaimed farmland with a century of growing history. Grove and ranch parcels here are prime farmland candidates. Browse Indian River County land.

Why buy land on the Treasure Coast?

The pitch is balance: genuine rural and agricultural land within reach of the coast, in a region that's growing without losing its open country. Inland parcels cost a fraction of coastal land, and working agricultural tracts can qualify for Florida's Greenbelt classification, which taxes farmland on its use value rather than market value and sharply lowers carrying costs (Fla. Stat. 193.461). For investors, St. Lucie's growth is the appreciation story; for lifestyle buyers, Martin and Indian River offer space and agriculture with the beach close by.

Buying Treasure Coast land

The usual rural due diligence applies: confirm zoning and future land use, check the flood zone, verify a parcel will support a well and septic, and confirm legal access. Pricing varies widely with acreage, water, and agricultural classification, so lean on current comparable sales rather than online averages. Our how to buy land in Florida checklist covers the full process, and the best counties guide puts the Treasure Coast in statewide context.

Frequently asked questions

What counties are on Florida's Treasure Coast?

The Treasure Coast is generally Martin, St. Lucie, and Indian River counties on Florida's central-east coast (some definitions add Palm Beach). All three pair Atlantic coastline with a large agricultural interior of citrus, cattle, and ranch land.

Where is the best rural land on the Treasure Coast?

The western, inland portions of each county hold the rural acreage: western St. Lucie's ranch and grove country, Indiantown in western Martin, and Fellsmere and western Indian River. These areas trade well below coastal land.

Is Treasure Coast land a good investment?

St. Lucie's rapid growth (Port St. Lucie is among the nation's fastest-growing cities per the Census) supports appreciation, while Martin and Indian River offer agricultural land that can earn Greenbelt tax savings. The right pick depends on whether you want growth or rural lifestyle.

Can you farm Treasure Coast land?

Yes. The region has deep agricultural roots, especially Indian River citrus and Martin County ranching and cane. Bona fide commercial agriculture can qualify for Florida's Greenbelt classification (Fla. Stat. 193.461), lowering the tax burden.
