We leased our property to these two ladies, both named on the lease agreement. One of the ladies moved out and so a new roommate was brought in. We, the owners need to move back into the property. We have given them 30 days notice. The lady named on the rental agreement has moved out, the new roommate not on the rental agreement has decided she needs another 30 days. Now she has stated she will get an attorney, so she can fight us and stay on the property. What can we do??
