What he has proposed is setting up the partnership where equity will be split 60/40, with him getting the 60%, but splitting cash flow 50/50.  

Justin, Ok first things first, on the surface it passes  the 1% test,  plus the 50% rule.

Shortly thereafter we purchased another duplex with a garage and shortly after that another duplex.Just when we thought that was it for the year having a goal of 50 units that I was leary of hitting, our broker called and said, hey I know where there are 12 more units that you can pick up for a reasonable price you just need to make an offer on them.

In the case of non-payment, breaking rules, etc., do I have to follow the same eviction proceedings as with any other tenant or can I just kick someone out? 

Either find a bank with shorter or no seasoning requirements, might take you a while, and by the time, 6 months or a year has gone by, and guess what, you met the seasoning requirements.I worked for finance company for a while, and they have simple rules to implement, such as income requirements, 12 months at the same job etc.

There's no perfect answer, because it will vary widely by location and the actual property. 16%-18% pre-tax profit (of sales price) is a pretty good rule of thumb.

We split all profit 50/50.Using super simple numbers to make the math easy.

There are rules about what can be deducted and what can't, and when you have to provide an accounting of the deposit and any remaining deposit to the tenant.

NOI rules valuation wise.I would highly advise all to read Multifamily Millions by David Lindahl.What I did wrong was I thought buying a yield deal would have been safer and I didn't follow David Lindahl's proven step by step path.
