All expenses must be paid from retirement funds. ( You can't use any personal funds or credit cards to pay bills on the rental). 

Are they different for rental property vs personal?

And with you using one of the units as an office would not eliminate the fact that you are 'disqualified person'.

Does having an LLC simplify any of that vs doing it as part of my personal return?

I've already done quite a bit of research in my area and can already pretty much tell you what a property is worth or at least generally what it will sell for as I spend about 3 hours a day looking at properties and have been doing that for about a year to make sure I'm prepared on the accuracy side of things.I do have a family member that is a real estate agent in the area, but I'm not sure if a standard single family residential agent is the correct connection for multifamily.

If they have potential I would like them to be sent over to a friend of mine (who's in sales and recently got his real estate license, he's got the perfect personality for this) to try and close the seller.
