In most states the info is available to the public at the county courthouse in the deed room or assessors office. Go to the courthouse for the county where the property is located, and look up that property address on the computer. (hopefully they are on computer). The last recorded note or deed to secure debt, etc, will have the name of the bank or lender who made the loan. It would show the borrower and the lender, and there should be a signature on it that may give you a name to contact for the lender. Most lenders will not sell direct, but if it is a smaller bank, they might. Most lenders will sell through a specific listing agent. If the builder has walked away recently, there may be a lawsuit pending, or the foreclosure process may not be complete yet. In some states this is a fast process, in others it takes longer. Plus the bank may sue the builder, further complicating the issue.
