Each new tenant I sign a lease with, always give me a new challenge to face. I recently signed a tenant on a month to month lease whom informed me that he will be changing his cell phone number hours after signing the lease with me. He also informed me that he maintains a seperate mailing address for his mail which he did not provide me a copy of.

   I have had other tenants change their number but provide me a new number, a month or two after moving; so should I be concerned? He had an out of state number which he maintained through his previous lease I believe, with another local landlord; so I just wondered if this would raise a flag to any other landlords here? He did offer a reason to validate the number change: stating he had lots of enemies he wanted to avoid, "Personally talking to this tenant, he did not strike me as a trouble maker but rather very bookish and easy going." My tenant  screening service which I have trusted for 9 years now qualified him through their checks, despite my investigating discovered a previous landlord reference to be inacurrate by phone number which he seemed very apologetic about. What is a good time frame for me to wait for him to give me his new number? I plan going to his employer to confirm his number had been changed if they will cooperate with me or should I give him the 7 day notice to provide this information? Sorry for any mispellings I am notorious for my grammer. One other hair raiser about this guy to me was the fact that he was moving from a $450.00 rental too my $300.00 rental and said he could not afford the $40.00 transfer fee nor to have the financial ability for at least two weeks. He does drive and commute to work and I know he has to pay for gasoline. I took the power out of my name after the walk through inspection, so he is currently in the dark.
