AWESOME Advice. Thanks everyone.
John D. - you are ABSOLUTELY right (it wouldn't be the 1st time I've gotten ahead of myself).
David Kang - thanx for the advice, the referral and your offer (I'm sure I will be contacting you as I begin to navigate this whole process).
Mindy Jensen - thanx for the advice on getting referrals & smoke remediation. I actually do KNOW how the fire started (the owner was smoking in an upstairs bedroom) so I BELIEVE the damage is fairly minimal (and contained) but someone I know said to me "oh, there's smoke damage, forget about it, the smoke permeates EVERYTHING and the only way to get rid of the smell is to gut the entire house (which is why I was worried).
CK Hwang - that you for validated what I was thinking. Yes, even if I "screw up" there should be PLENTY of $$$ left-over. I'll have to do a more detailed analysis as I move forward, but the house was bought in the 90's for 2 1/2 times LESS than what the low-end of the market is doing for that area (so it SEEMS pretty-well idiot proof to me).
Thank you EVERYONE!
