Investing in Clay County, FL Real Estate: The Actual Numbers
Considering rental property in Clay County, FL? The typical home ($337,847, Zillow) against typical rent ($1,863/mo, Zillow Observed Rent Index) works out to a 6.6% gross cap rate. Gross is where analysis starts, not ends — below is the investor cost stack that turns it into a real number, and the demand-and-supply data that decides whether the rent holds.
Clay County yield at a glance
The investor cost stack, worked
Start with $22,358 of gross annual rent. Property tax: investors get NO homestead exemption and no 3% cap — at Clay County’s typical 15.05 mills on a $337,847 assessment, roughly $5,086 a year (non-homestead assessments can still rise up to 10% annually). Insurance: Citizens averages about $1,189/yr here, and landlord (DP-3) policies typically price above owner-occupied. That already takes the yield to about 4.76% 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 +1.5% (Zillow index). On demand, IRS migration data shows a net 3,611 people per year into the county; on supply, builders pulled 1,522 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 undervalued by 20.2% versus income-and-rent fundamentals.

The Clay County market, in context
Clay County is the value play of Northeast Florida — more home for the money than St. Johns or the Duval beaches, with Clay County District Schools and an easy commute to Jacksonville's Southside and NAS Jacksonville. Growth is concentrated in Oakleaf, Fleming Island, and fast-rising Green Cove Springs along the new First Coast Expressway, which is reshaping where the county builds.
The economy behind the market: {'drivers': 'healthcare, retail and logistics, public sector, and a large Jacksonville commuter base', 'summary': "Clay County's economy leans on healthcare (Ascension St. Vincent's Clay County and nearby Orange Park Medical Center), retail and distribution along the US 17 and First Coast Expressway corridors, and a public sector led by the county school district and government. Just as important is what is across the river: a large share of Clay residents commute to Jacksonville's Southside and to Naval Air Station Jacksonville, so Duval's deep military, healthcare, and finance economy underwrites Clay housing demand.", 'employers': ['Clay County District Schools', 'Clay County government', "Ascension St. Vincent's Clay County", 'Orange Park Medical Center (HCA)', 'Walmart', 'Publix', 'First Coast Expressway corridor retail (Oakleaf)'], 'jobNote': "Many Clay residents commute to Jacksonville's Southside and NAS Jacksonville, so Duval's economy is a major demand driver."}
What could change it: Clay's risks are riverine flooding (Black Creek and the Doctors Lake/St. Johns shoreline can flood in major storms), rising insurance, and the growing pains of fast expressway-corridor development, including county budget pressure as commercial construction cools. Inland and away from the water, risk is comparatively low for Florida.
Near-term outlook: Expect Clay to stay the region's steady value market over the next 12 months. Demand from buyers priced out of St. Johns and Duval keeps a firm floor under prices, while heavy new construction along the First Coast Expressway keeps a lid on resale appreciation — a healthy, buyer-friendly balance.
