Joshua, Are you working with any sort of a mentor? They could probably help you with the details of this. Even when my buyers are buying a home that is "as is"- if there is a major problem that wasn't obvious upon walking through initially, I ask for it to be repaired or credited (when possible). In most cases, whether it has been an REO, a short sale or distressed sellers they have gone through with it. If they don't, it must be in the disclosures for the next potential buyer, and they may end up not selling it anyway.
Hope this all helps!
