Sorry to hear about the loss of your home and I assume you have resolved all methods available to keep your home and you have consulted with an attorney. But at the end of the day, if you are the previous owner of record, you have as long as the new owner allows you to stay. There is no 30 or 90 or any amount given to you. It is entirely up to the new owner. New owner may elect to even renting the home to you but that is something you should negotiate if you both parties are interested.
As far as the attached appliances and other attached items, those items are also property of the new owner and removal of those items can be cause for criminal charges against you. The attached items are part of the sale, just like the toilet, flooring, window coverings, etc.
"Cash for keys" seldom happens in a trustee sale acquisition but again, if you are able to negotiate something with the new owner, great.
Our team purchase properties on behalf of investors almost daily in the Phoenix metro area. And against popular perception, many of the homes are left behind by the previous owner in amazingly good condition. I believe it's a matter of pride; one may loose their home due to economic or other factors, but most people don't want to be thought of poorly.
Most likely you will be able to turn your life around to the positive after this experience. Take it as an education and learn from it. Best of luck to you.
