I'm with Ilima! Do what you can to get off the lease. If she's not going to recommit for a year, that mean she's going to have to move. Some places will make you move if you don't sign a lease after a few months (depending on whether they have people waiting to move in, I guess). They'd rather have someone on a 12 monther than a month-to-month.

Your sister is not treating you right, especially since you've been lending her money. So what if she feels the pressure of signing another lease? She can move and get you out of the bind, or she can stay where she is for another 12 months. She already sees you as a soft-touch; don't be so easy on her anymore.
