First rental- self managed

[James York]

I am moving from selling my spec homes to keeping them. I am ready to lease the first one, but am struggling with the first month's rent. Let's say rent is $1000/month due on first and security deposit is $1000. Lease is going to start 9/15 so I need to collect that prorated rent. Do I collect $1000 rent and $1000 deposit on 15th and then pro-rated rent on 10/1 or to I collect prorated rent ($500) and deposit on 15th with $1000 due 10/1? I realize perdiem may not make it exactly these numbers, just using simple numbers to understand. THANKS!!!
