Awesome! Thanks, everyone, for the replies! I have a friend who's just starting out as a real estate attorney, and I think there's a pretty strong chance she'd be willing to cut me a discount if I'm willing to take some losses as we both learn the ropes. Could be the start of quite a partnership!
I've also read that we apparently have a new law on the books that intends to give "counties additional tools to transfer properties that languish in tax sales to a nonprofit organization, neighbor or other party who agrees to repair and maintain the property." I would LOVE to have a nonprofit organization that renovated these homes to be handicapped accessible and sold them at reasonable prices. I'm still reading about it, but some of the information can be found here:

I'm no attorney, but it sounds like the door may have just been opened to exactly what I want to do?
