Can you live off-grid in Oklahoma County, Oklahoma?
89
of 100
Good with caveats
Yes, with two things to plan around. Wells are shallow here, near 110 feet, which keeps drilling costs down. NOAA counts about eight strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan. Flood zones cover parts of the county, so look up any parcel on FEMA's flood map before you offer.
