Answer 1

*most* structure fires the houses are total losses where it burns down to the ground. Most areas, especially with those with professional paid departments, usually get the fire under control before it causes a total loss. These houses will general have lots of “clues” on what started the fire. Most house fires the houses are able to be rehabbed and used again.
