Good with caveats
Yes, but hurricanes will be the challenge. NOAA counts four hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages. Water is easy here, with about 62 inches of rain a year and wells near 200 feet. The growing season runs about 271 frost-free days, long enough for a spring and a fall garden.
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.
About 62 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 200 feet deep; a well typically runs $8,000 to $18,000
Growing season
Long enough for a spring and a fall garden.
About 271 frost-free days, USDA zone 9a; last frost about March 2, first about November 30
Sun
Good sun. Size the array and battery bank for winter.
About 5.4 hours of full sun a day, averaged over the year
Flood
Flood zones run along creeks and rivers here. Look up the parcel on FEMA's flood map.

Storms
Expect about two hurricanes within 50 miles over 30 years. Build to the wind code and keep a week of fuel and water. Strong tornadoes pass through now and then. A safe room is worth pricing.
NOAA: four hurricane-strength storms within 50 miles since 1975; about 2 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Flat to gentle, easy to build on.
Slopes average about 3%, about 90 feet above sea level
Soil
Sandy and fast-draining. Septic may need an extra treatment step, and garden beds need compost to hold water. The county's soil test decides.
Sand, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000
Road
Paved roads are close by.
