Everything seems to point to the MLS providing a structured market place for buyers and sellers to connect and engage in business.

Looking forward to engaging with the forums and meeting people in my community. 

I'm fortunate enough that my wife and I have been working on our finances and credit ever since we got engaged to the point where we can get almost the very best financing deals out there.

Many of our clients start with Turnkey to get the ball rolling, and then start building a more DIY portfolio alongside, knowing they have a more passive, reliable income source backing them up if a deal falls through.

. – none of which is applicable when the LLC strictly engages in paper transactions without employees and a physical office. 

I’m fairly new and have not taken the time to set up key word searches for the forums so I mostly stay engaged in the “trending” topics.

Well currently I'm CS Executive Student (a professional course from The INSTITUTE OF COMPANY SECRETARIES of India) and also I'm engaged in a Network Marketing business.

@Lee Ripma is correct - as a California resident actively engaging and managing an LLC from California, California will declare nexus and require a registration, a tax filing and a minimum $800 fee each year.Marketing into other states may or may not create nexus (depending on each state's laws, so look them up) and need to register/file in that state, but as @Wayne Brooks indicated, you will most certainly need to be registered in any state where you want to sign contracts and otherwise conduct business in that state.From each state's point of view, anybody who wishes to sue you must be able to do so in the state where the transaction took place so you must be registered in that state with an agent who can accept legal service on your entity, should the need arise. 

It is extremely rare that a buyer or seller in a residential transaction will engage an attorney.. 

This, specifically, is to be applauded in my opinion:To encourage more landlords and property managers to participate in the HCV Program, HUD’s new Landlord Task Force will host a number of forums across the country to engage directly with housing providers, specifically those who do not participate in the voucher program.
