Last year, I talked to the lawyer representing the owner. The woman who used to live in the house is now living in a nursing home. I am not sure if she is able to make decisions regarding the house. The house is somewhat in limbo, as apparently the bank "won" the foreclosure using fake documents (part of the larger LPS/robo signing mess if you read the news about that). Since then, the house is mostly being "maintained" by neighborhood volunteers. There was one of the second-saturday cleanups that focus on it, and neighbors occasionally mowing the grass and cleaning the porch / boarding some windows.
It is pretty obvious that the house is in dire shape, and needs some help soon. Due to its significance right at one of the entry ways of Springfield, there is a lot of community support to preserve the house, and I would think that the community will rally behind everybody taking on this job.
As Bill said, Springfield Chicken has made attempts to put buyers in touch with the owner, but I think right so far, there was no/little success. Check with her to find out more details.
More of the court documents and such regarding the foreclosure can also be found on the Preservation SOS forum.:http://forum.preservationsos.org/viewtopic.php?f=21&t=515
