Technically anything "attached" to the home is supposed to stay, like ceiling fans, fixtures, dishwashers, etc. But if you are going to take the ceiling fans, I would replace them with a light fixture or a cheaper ceiling fan. The appliances are not "attached" so if that is your property, then take them with you.
Also, if you can find out who the agent or company is that will be handling the property management or eventual sale of the home is, you can explain to them that you are a tenant. Tenant's have rights as well and that way the management company the bank hires, won't lock you out of the home thinking the home was abandoned.
Do what you can to find out who the home has been assigned to, the company or agent, and open a line of communication with them, it is the best thing that you can do. That way there won't be any unexpected surprises. Your sitiation is not unique and has happened to many renters the past few years.
Good Luck !
