I think you got your answers above but I do recommend the book.  Keep

I’ve purchased my first duplex and I’m trying to figure out how to do the property management aspect as well as the book keeping since they seem to be separate.

So when I was there, one of them was home and asked about the security deposit; I explained to her how what was in the lease was the way it worked with any professionally managed property and that I had no control over when exactly bookkeeping cuts the check, and she was fine with it.  

Accounting/bookkeeping, collections, evictions, maintenance, etc.

The majority of this business is simple book keeping and people managing, but what is going to make you a huge success is the ability to get your message/product out and in front of people in a coherent manner.  

I do the online version so my book keeper can get to it easily.  

This is a big convenience to the tenant and significantly reduces the bookkeeping time involved for the landlord.

You can take draws anytime, there are no  restrictions, more draws just might your bookkeeping more difficult, that's about it.Commingling only plays on a business entity and personal funds transactions. 

I would talk with the PM about how they handle evictions, how fast, repairs, do they do basic book-keeping, etc. and ask them if they can get the current tenant in the other unit a month to month lease-so if that tenant turns out bad you've already got them on a month to month and it's easier to get them out and get a new tenant in. 

I will run it by my book keeper to make sure it works.Thanks again to you both!
