The only thing I can think of at the moment is get a large, military type canvas tent (think of the MASH tent). While you and the girls live in it, you dismantle the current house, dry out the wood and insulation before it can mold, then use the materials to construct something livable. Do sorry you are going through this :( ....
Thanks @wrestlingdesires, we certainly need an alternative, that is for sure. I just don't have the finances for it at the moment unfortunately. I do like the idea of a Mash tent though xx
If it comes down to it, you can do what some friends did on their property (large family with kids of all ages).
Please note this was a year round HOME complete with wood and cook stove. It's a viable option until you have the finances to upgrade, they lived comfortably there for years.
