Non-refundable damage deposits?

[Blake King]

Hi everyone!

This is my first time starting a new lease that was not an inherited tenant. Luckily i got pretty lucky with the inherited tenants, i know thats usually against the rules ;) 

I am looking for advice on damage deposits and non refundable damage deposits more specifically. My father owns a few properties in Marysville, my property is in Mt. Vernon. My father told me to collect $300 as a non -returnable fee, for cleaning etc, as well as first months rent of course ($1200), a $900 refundable security deposit (with the fee totaling 1200) . They also have a small dog, so we are charging them only $20 / month pet fee, as well as $200 non refundable pet fee and $800 refundable pet deposit.

I am not sure about all of these non refundable fees and deposits. I want to make sure i am covered, but we also are renting to mutual friends, which i was unsure about. Is this pretty standard to have non refundable fees for cleaning etc? 

Thanks for the help!
