The ability to "talk the language" without needing an "interpreter" seems to give me the arsenal for success while minimizing the dependencies.I am looking at Temple University Real Estate Institute's online coursework.

Training can be fairly minimal as long as the call center has agents with good English and phone skills - and your manual is solid.

To minimize transaction fees, custodians can cut checks for recurring costs -- such for trash collection -- to cover three to six months of payments.

However I'm trying to find what the risk here is and how to minimize it.

Not All Fun And Games....Now I don't want to minimize it, or make light of it.  

@Chris Newman:) I wasn't minimizing the possible contamination (okay, I was...) because the truth is that it's fairly irrelevant for people doing day to day things.  

Minimally, I would request all deposits + proration of rents already paid.

I don't mind spending a little time talking to people and trying to assist them with their transaction whether I can be a part of it or not, but I would like to minimize the time I spend visiting properties if I can rule them out by asking the right questions.

Also 35% expense ratio could be legit if the building is in great shape in a high rent area, but for a long term hold including CapEx, you might want to double check those expense numbers.For multifamily, even in good blue chip areas, I personally look for a minimum of 7% combined annualized return since I get that with minimal risk today.

The reason that the house was shown "open-house" style is, ostensibly, to minimize the impact to the existing tenants.
