Texas · Off-grid & homestead potential
King County scores 35/100 on the Bolthole Index, a marginal county profile. Its strengths are low administrative friction for a quiet rural property and deep seclusion — about 11 people within a 30-minute drive. The trade-offs: thin water margin (23.5″/yr rainfall) and elevated mid-century heat, water, rain, or wildfire exposure.
