For the standard person, I can't find justification for an LLC.For the person who owns 20 properties, a couple commercial buildings, and a 50 unit apartment complex, sure. 

Those people who call themselves "Wholesalers" are just kidding themselves, if you are an investor you are buying below retail market value to make a profit, why not just, if you really need a title, consider yourself an investor.

Since most PM companies require a cash account to immediately draw upon for expenses, there is really no justification for additional charges except profit.Many folks cite the monthly fee as their first reason not to hire a PM. 

There are always private money lenders that don't care about income, just if the numbers work on the property.  

The justification that the broker / seller used to account for the difference?

If not, I'm not sure there would be enough justification from his perspective. 

Rent would most likely decrease to about $1700, but I would be getting a very good deal on a 3/2, better than anywhere else I would be willing to live by a large margin.I'm keeping vacancy rates very conservative despite the fact that I will be occupying one of the units and not factoring any money going into the house immediately as it is move in ready and some major repairs are being made (new roof and siding) price to the sale.I realize that seems like a lot of justification, and it might be a little, but the sheer prices of rental units down here, decent ones, is unlike anything I have seen.

You say it as if You have all the right or justification to do something.

If they are on a month-to-month, you can give them a 30-day notice and don't even need justification.

They start with that price, then work backwards to see if there is justification in the market for that price.
