Good with caveats
Yes, but hurricanes will be the challenge. NOAA counts five 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 67 inches of rain a year and wells near 120 feet. Flood zones cover parts of the county, so look up any parcel on FEMA's flood map before you offer.
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 67 inches a year (PRISM, 1991 to 2020 average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 120 feet deep; a well typically runs $5,000 to $12,000
Growing season
Long enough for a spring and a fall garden.
About 262 frost-free days, USDA zone 9a; last frost about March 5, first about November 21
Sun
Good sun. Size the array and battery bank for winter.
About 5.3 hours of full sun a day, averaged over the year

Storms

Road
