Possible, but hurricanes will be hard. NOAA counts three hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages. Rain is plentiful, about 60 inches a year. Septic will likely cost more, because the soil stays wet for long stretches.
What the land says
Rain
Rain can supply much of a household's water with a large tank. The sandy soil dries fast, so plan to water the garden.

Deep wells. Get a driller's quote before you offer.
The typical well here is about 330 feet deep; a well typically runs $11,000 to $25,000
Growing season
Long enough for a spring and a fall garden.
About 292 frost-free days, USDA zone 9a; last frost about February 24, first about December 3
Sun
Good sun. Size the array and battery bank for winter.

Storms
Expect about two hurricanes within 50 miles over 30 years. Build to the wind code and keep a week of fuel and water.
NOAA: three hurricane-strength storms within 50 miles since 1975; about 0.3 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Flat, but the ground stays wet. Build on the higher, drier spot.
Slopes average about 0%, about 20 feet above sea level
Soil
Expect a costlier septic system, because the soil stays wet for long stretches. The county's soil test decides.
Sand, poorly drained (USDA soil survey). A mound, sand filter, or treatment unit typically runs $10,000 to $20,000
Road
Paved roads are close by.

Well cost
Get a driller's quote.
Wells here run near 330 feet, so the well is a large cost.
Soil test
Get a soil test before you count on septic.
The soil stays wet, which can rule out a standard system.
