Good with caveats

Yes, but hurricanes will be the challenge. NOAA counts six 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 65 inches of rain a year and wells near 50 feet. The U.S. Forest Service rates wildfire risk high in parts of the county, so plan cleared ground around the house.
