Do you pay the rent on time? If you do i dont see any reason why your landlord would evict you. Most landlords just care about the money, why would they risk losing a source of income because of the mess. I mean as long as it's tidy when/if you move out they shouldn't have any problems with you. I don't know much about how it works in the US but over here I think if you get made homeless the local council will give you emergency housing (if you don't have a job).
