Owner-Occupied Help!

[Jennifer Sleider]

I purchased my first investment property two weeks ago. It is a duplex. I will be living in one unit and the other unit has a long term tenant in there that is currently on a month to month lease. I have a couple questions that I could really use some help on from anyone else that does an owner occupied! 

1. I know that living on the premise will allow for the tenant to access me anytime she hears me. I am drafting up an estoppel to summarize some of the original lease agreement. I would also like to add something to it that covers how the tenant should contact me. Any suggestions on a nice way to put don't ask me to fix your garage opener while I am carrying my child to the car in the morning on the way to work? As an example. 

2. How should I ask the tenant to deliver the rent? I want to ensure that it doesn't get left somewhere that it could get lost or for them to claim they gave it to me, when they might not have. Any advice?

I appreciate any and all help!
