Buying fire damaged houses

[Mark Rowan]

After watching a house up the street from me get rehabbed after a fire. I started thinking that I might like to look for properties that have fire damage both for rehabbing, and wholesaling. I'm a firefighter, so It is easy for me to find where the fires are. My question is this, How do you tactfully approach someone who's house just burnt down and say, "hey, do you want to sell your house?" I just don't want to look like I'm taking advantage of their bad situation. So, if you have purchased fire damaged houses, how did you approach the owner? Thanks.
