What past problems has the seller had with the house?
This coincides with the Transfer Disclosure Statement mentioned above. But often times the seller will repair the problems and not disclose them if they have been repaired. Seller disclosure forms often do not require disclosing past problems that have been corrected. There may be some things that have been fixed that you want to know about. For example, major structural problems, plumbing and electrical defects, roof leaks, fire damage and drainage problems that might reoccur. It is better to know about them ahead of time.
