Usually if it's not listed there is a good reason for it. When a bank wants to sell they will want it listed to expose it to all. Be careful buying REO/Foreclosures, they come with no disclosures. It is strictly buyer investigate and buyer beware.
Find a realtor that has practical construction experience and not just layers of disclosures and cya.
