Anyone worked on a fire damaged property?

[Silvia Ochoa]

Hi, I have my eye on a fire damaged house going for 75k in an area that comps for 200k. The numbers look good but I have never dealt with a fire house. Walls and structure look good but the entire roof will need to be replaced including the rafters. And to make matters worse, it has been raining like crazy so I'm sure there will be water damage because of it. 

Please share your stories dealing with this type of situation. Like they say, "You don't know what you don't know". Any insight into what I can expect will help me make a better decision. Thanks.
