Thanks for the reply.
Since I posted this question a few weeks ago I have since put an offer in on the house. We're in the middle of the offer/counter offer deal right now.
I talked to an engineer who is going to inspect the house (assuming Freddie Mac and I work out the offer). I'll see what he says after inspecting the house. I hope that it is something I can deal with myself. I've never had to try anything like this myself,but logic,common sense and asking a lot of questions usually gets me through things. If it looks like it will be too big of a job for me to tackle,I'll hire it out.
