What to do about a house in Candler County

Check the parcel against your state survey sinkhole map, and ask for an inspection if cracks, depressions or sticking doors show up.

That works out to roughly 243 of Candler County's 243 square miles on soluble rock. With about 11,130 residents (46 per square mile), there is effectively nowhere in the county off the soluble rock, town or country. The figures come from 252 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.

Worth reading for this county: why the 100% under cover still counts, and the signs to look for and how an inspection works.
