If she is not on the note then the rental agreement is between both of you and whether she owes for July or not depends on what was agreed. Hopefully you can resolve this before it leads to conflict..
I hope her moving out doesnâ€™t cause you a hardship. If youâ€™re considering selling, please feel free to contact me directly email@example.com or by phone 407-832-4650.
Iâ€™ll be glad to help you.
