Never allow a tenant to tell you how you are going to get paid and when. The deposit is not for rent payments. It is for leaving the place clean and for the painting, carpet replacement and repairs you have to make after they are gone. Serve your tenant a 5 day pay or quit notice now. Mail another notice by receipted certified mail immediately. On the sixth day, file for an eviction. Pick up the forms at the court house and ask for instructions if you need them. State the reason for the eviction as nonpayment of rent. You have to move now so the certified mail and the eviction certified notice can be mailed to your tenant. Otherwise, your tenant will evaporate. In this case, the mail will go to your address. Do not sign for the mail if your tenant is not home. Ask the mail carrier to leave a notice to pick up with you. Be sure to file the eviction if your tenant is not out within 5 days. It is the only way you can be sure the tenant will leave. She may get used to idea of free rent. Change your locks immediately after she is out. Not before.
