I am sorry for what has happened to you. I have a guy that i work with that speciffically works with people looking to buy/refinance homes but have credit issues. He is an ex mortgage broker so knows what needs to be done how to do it well and i can assusre that he can assist you. I would be more than happy to give you his information as he would be able to help you remove the collections caused from identity theft.
If your interested please let me know.
Best of luck to you!
