Chances are this home won't be sold to anyone anytime soon. Bankruptcy all be ends any transfer of ownership as the court must approve this. If you want to pursue it further, contact the owners directly and ask if they want to sell. If you get a "yes" get an agent or attorney involved to prepare your paperwork, market analysis and then be prepared to wait for court approval. Chances are that the home may be "underwater" meaning the owner owes more than it's worth. Now you've added to your complexity multi-fold. Not only must you get the courts permission, you need to get the banks permission. This process can be 6 months to a year or more.
You may be better off finding another home.
