With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.

Also the agreement was more beneficial to them than to me. 

The increased risk is generated by the fact that the owners are relying on the validity of the tenancy in common Agreement for their usage rights, and it is possible to imagine legal circumstances under which this validity might be undermined.- If the subdivider or someone with relationship to subdivider sells, a public report must be done.

Basically common contract or agreement law.

My GUESS is these homeowners have been tricked/screwed in to signing a long term power purchase agreement, often with no buy out provision.

@Michael Darten  Most property management agreements have the monthly PM fees based upon a percentage of rents collected.  

You would have to go after the one individual for non-payment and you could only remove the other three by going through the legal process like you would for someone on a verbal agreement, which puts you in a he-said, she-said situation. 

As we work in Chicago, we structure our agreement around these concepts.

They have the correct lease agreement and disclosures and make it much easier.

It also is helpful to have a California LLC in case you ever sell that property and move into another state so that you do not need to form a new LLC altogether with new operating agreement, just re-register in the new state as a new foreign LLC.
