Property Damaged: Wrap Around Mortgage

[Account Closed]

Hello BP, i'm doing Wrap Around Mortgage and a possible bad situation idea occurred to me. Let said the property is heavily damaged from a natural disaster and the buyer default because he can no longer live in the property. The property will be returning back to me because it is a collateral, i'm in a bad position as the property can no longer be livable now and the value is obviously lower. And let said even if i had foreclosure the property, the buyer cannot paid off the deficiency judgment due to the unlivable house. What am i suppose to do, or is there a better legal agreement?
