If the tenant has any issues, they would be able to call me. The best option will be to call me on my phone line. The tenant will be provided with all of my telephone numbers, and should be able to reach me no matter what. When the cellular phone needs charging, I will have the phone plugged in next to my bed, so the phone ringing should wake me up. If for whatever the reason, I don’t answer the phone, leave a message. I won’t know that you have an issue if the tenant doesn’t tell me.
