If it is a preforeclosure, the larger banks wait until it is an REO property. Has it been foreclosed on for sure?
If not, you would need to find the owner.
Are there winterization stickers yet on the property? If so, the company that did that might be able to tell you who the bank is that they winterized the property for. If it is a small bank, then you might be able to get or have an agent get more info for you.
