We bought our TV home as a resale in late '07 and were able to get sinkhole coverage added after an inspection in early '08. The "rules" that insurance companies put in place re: sinkhole coverage/availability are constantly changing. We've been lucky so far and the policy including sinkhole coverage has been extended to us each year since.
