You aren't forced out until it sells and the new owner wants you out (usually at closing, but if it's an investor he may be willing to make other arrangements for you). It's not the trustee you have to deal with. Of course, you want to clean up the place and keep it in a marketable condition through the process both for your own benefit and that of the bankruptcy estate (keep the trustee happy). There's no need to negotiate with the trustee (and frankly it's probably improper for him to do so). He's really only has too options, allow the bank to foreclose or put it on the market.
