As Nate also pointed out, going forward it's import to specifically outline in detail what is Tenant vs.

I would definitely set up separate accounts for your business banking (income and outgoing payments), and another for security deposits only.

I've also heard of folks having the outgoing tenant record a video of the unit condition and have the incoming tenant record a video of the unit condition.

@Susan Reehill you put a negative number in the gas and other category, which means you are getting income from those categories rather than outgo.

I have been underwriting many deals in my market and have encountered a deal requiring loan assumption on a 20-unit apartment.I have many questions to ask, but I want to understand from here before meeting the owner's bank and outgoing owner.Q1. what are some of the fees besides assumption and processing fees to anticipate?

I would say unless you have a compelling reason to get out, stay the course or if you do get out go guard or reserves.

Having said that, here is what I would look out for: Is the property zoned and permitted as a 6-plex, or did they just DIY 6 units out of a SFR or 4-plex etc. w/out going through the system? 

(The fact that in reality, there would be no income coming in from the unit that you'd be occupying, only affects the outcome as to whether your monthly outgoings would end up being less than if you were renting in that same unit, or more, or about the same.

@Dawn Brenengen I have to agree with those here that have said to verify the story/charge, and assuming it checks out, go ahead and rent.

To make it as a r/e agent you have to have a big network of people, like by being active in civic groups / clubs, church, etc, You have to be very outgoing, charming & trustworthy.
