I am from Arizona, He talked about how much more difficult it was to be sued with an LLC from Nevada and that the anonymity of the owner of the LLC was kept secret.      

I'll answer your question in that I am in consumer lending but would prefer anonymity beyond that.

Email and text is too anonymous, plus you can tell a whole lot more about a person by speaking to them.

If there is any type of anonymity of the Seller, expressed by the broker, then RUN.

I use land trust for anonymity purposes in which the beneficiary is a series LLC. 

You appear underwater so people don't have an incentive to sue you.The idea is that you create and control an (anonymously owned) entity that records loans to your properties (often without any payments) that grow over time so you never appear to have any equity.

Your goals, family and financial future are more important than some tough love feedback on a rather anonymous site.  

I called the state, anonymously, to get access to the building codes.

Trust provides anonymity (providing you close on your properties in the name of the trust) and the LLC provides liability protection.

The only reason the seller's daughter even knew of my company was because she got an "anonymous" contact that told her that her house was on a website she's never even heard of called Biggerpockets.
