The landlord may be able to boot you out faster since it is owner occupied, but certainly not overnight. Not legally anyway.

If you are booted illegally you will have options to consider, but it sounds like your options would be limited as these owners likely don't have the means to pay any damages owed.

As above- the faster you get out on your own the better.

I'd bet they would not pursue you for unpaid rent if you bail out early. Keep your money and move out now. If they make demands for payment you can negotiate a settlement later.
