Give them proper notice and get them out2. 

But to mandate or regulate how a auto manufacturer sells there goods is insanity, at best, and I'd argue quazi-communist at worst. 

Proper structuring with professional guidance is key to achieving both parties' goals.This post does not create a CPA-Client relationship.

Thanks James for the proper terminology.

You want to properly classify transactions such as Contributions/distributions if they are between the entity and the owner itself.If the entities are not direct owners, you have have a Due to / Due From to properly keep track of money owed between the entities.Best of luck!

I had a good-paying job at a Silicon Valley equipment manufacturer. 

There are three items required to make a successful partnership - Time, Experience, Capital.If you are a syndicator, you are likely expected to have time and experience.There is a lot that goes into being a competent syndicator - Proper communications, finding a good deal, communicating quarterly updates, networking with lenders, contractors, PM companies.You can gain experience by doing your own deals or working for someone who does(Ideally both).I personally think you should cement your experience before worrying about OPM.Best of luck

Several things to consider: 1) One of the main purposes of segmenting your assets into separate LLC's is so that your personal net worth or equity in other business ventures or properties isn't exposed, so unless you have a high net worth or a lot of equity in a property, it might not be worth bothering going the separate LLC route, especially when it restricts your financing of the property.  2) Most any commercial financing you get from a local bank for a small property is going to have recourse anyhow and require that you sign a personal guarantee, so you're still personally on the hook to the bank even in the case of a commercial loan.  3) If you're a newer investor and buying a deal that's tight on cash flow, or if you don't have a ton of cash sitting in the bank already, your greatest risk factor as an investor is your investment failing economically due to poor financing terms or not operating the investment properly, not because you get sued. 

Failing to follow proper procedures will cause even more delays.  

There's no right or wrong way to do this, just varying levels of risk and the only proper route is the one you understand.
