Found Fixer Upper

[Nicholas DeGaetani]

I found a home at the right price but needs a total cosmetic makeover. I found out from the realtor that it had been under contract and the inspection revealed in so many words:

-there is an underground storage tank (I'm assuming underground here)

-"water intrusion" around window and exterior wall. It also stated there was "potential for organic growth". Home inspectors are not allowed to use the word "mold" because they are not specialists in that field. However, given water intrusion combined with potential for organic growth, I would assume that's where the inspector was going with that.

Can someone who's been through this scenario comment on things to look out for? I'm trying to frame what I'm up against in terms of cost, risk of mold, and level of effort. Obviously without having a specialist come look at it that's a difficult question, so what do the worst and best case scenarios look like?
