St. Lucie County yield at a glance
The investor cost stack, worked
Start with $28,594 of gross annual rent. Property tax: investors get NO homestead exemption and no 3% cap — at St. Lucie County’s typical 22.85 mills on a $373,333 assessment, roughly $8,532 a year (non-homestead assessments can still rise up to 10% annually). Insurance: Citizens averages about $2,332/yr here, and landlord (DP-3) policies typically price above owner-occupied. That already takes the yield to about 4.75% before vacancy, maintenance, management and any HOA — the line items that separate real operators from spreadsheet optimists.
Will the rent hold? Demand and supply
Rent growth here is running +1.4% (Zillow index). On demand, IRS migration data shows a net 10,167 people per year into the county; on supply, builders pulled 4,008 residential permits in 2025. Rising rents plus positive migration plus a restrained pipeline is the configuration that protects yields; the reverse erodes them. Our valuation model currently reads the county as overvalued by 9.9% versus income-and-rent fundamentals.

The St. Lucie County market, in context
St. Lucie County is Port St. Lucie and Fort Pierce — one of Florida's fastest-growing and most attainable coastal markets, anchored by the giant Tradition master-planned 'new town' and a Cleveland Clinic medical hub. It offers Treasure Coast beaches and new construction at prices below the southeast metros.
The economy behind the market: {'drivers': 'healthcare, distribution and logistics, education, retail, and construction', 'summary': "St. Lucie's economy is built around growth itself: Cleveland Clinic Tradition Hospital anchors a fast-expanding medical sector, the 1,200-acre Southern Grove jobs corridor along I-95 has attracted distributors like Cheney Brothers and Amazon, and education (Indian River State College) and a deep construction-and-services base support the boom. Many residents also commute toward Palm Beach County.", 'employers': ['St. Lucie Public Schools', 'Cleveland Clinic Martin Health / Tradition Hospital', 'Indian River State College', 'Cheney Brothers (Southern Grove)', 'Amazon', 'St. Lucie County government', 'City of Port St. Lucie'], 'jobNote': 'The 1,200-acre Southern Grove / Tradition jobs corridor along I-95 is drawing distribution and healthcare employers, led by Cleveland Clinic.'}
What could change it: St. Lucie carries Treasure Coast hurricane and storm-surge exposure on the barrier island and along the St. Lucie River, with rising insurance and FEMA flood considerations on the coast. Inland Port St. Lucie and Tradition carry lower surge risk but face the strain of explosive growth on roads and schools.
Near-term outlook: Expect St. Lucie to remain one of Florida's fastest-growing counties over the next 12 months, with affordability and the Tradition/Cleveland Clinic story pulling strong in-migration and a heavy construction pipeline keeping buyers in a strong negotiating position.
