Bank changed locks!

[Gail Smith]

I've been working on a short sale. Unfortunately the bank rejected our first 2 offers and "closed our file". Then they winterized and changed the locks on the house but they haven't filed Lis Pendens paperwork yet. I have other interested parties but can't get inside to show the condition of the house.. I would think that the property is still legally the sellers in spite of the fact that he is behind on payments until the paperwork is filed with the county...am I wrong?
