Typically someone who leaves their property like that for so long may lose a lot of rights to it. Here, regardless of "fix" they likely charged you storage and that can add up to thousands over 6 months. To hold a sale they have to properly notify you and post sale, the same. I do fear you are well behind the 8 ball here as it sounds like you have few if any writings. Maybe a B.A.R. investigation is the place to go?
