Hi El!! I'm glad you made it to your brother's!
Sorry your house is stuck there. You don't want to leave it empty too long, maintenance and things will cost too. You can try to rent it out with a rental agency (a whole other set of headaches), or, you'll have to drop the price to sell it. More importantly, I hope you're feeling better. Getting that house settled will reduce a lot of your stress. Take care of yourself.
