Good with caveats

Yes, with two things to plan around. Water is easy here, with about 61 inches of rain a year and wells near 190 feet. Flood zones are common here, so look up any parcel on FEMA's flood map before you offer. NOAA counts three hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages.

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 61 inches a year (PRISM, 1991 to 2020 average)
Wells
Typical well depth. Budget for a mid-range well.
The typical well here is about 190 feet deep; a well typically runs $8,000 to $17,000
Growing season
Long enough for a spring and a fall garden.
About 274 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 5.3 hours of full sun a day, averaged over the year
Flood
Flood zones are common here. Look up any parcel on FEMA's flood map before you offer.
FEMA maps flood zones across much of the county
Wildfire
Moderate wildfire risk. Keep brush cleared around the house.
U.S. Forest Service wildfire hazard map: Low to Moderate here
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: three hurricane-strength storms within 50 miles since 1975; about 2 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 2%, about 100 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.
Nearest paved road usually within about 1.7 miles (OpenStreetMap)
