Either get strong insurance protection or go whole-hog on doing an LLC correctly. 

Assistance animals perform many disability-related functions, including but not limited to, guiding individuals who are blind or have low vision, alerting individuals who are deaf or hard of hearing to sounds, providing protection or rescue assistance, pulling a wheelchair, fetching items, alerting persons to impending seizures, or providing emotional support to persons with disabilities who have a disability-related need for such support.

Grouping the nice homes together in one LLC and the low end units in another, etc. etc. does nothing for liability protection, or accounting/paperwork reductions.

Either do it right and get the protection, or don't do it at all.

We just ended up building the business around syndication as it offers some good legal protection or structure around partnerships for acquiring large multifamily.

I was informed by a few lawyers that this type of LLC has not been seriously tested in the court of law so they are uncertain as if it will add additional protection or not.

Aside from an LLC, a Trust, or a partnership, there aren't many other options for asset protection or operating under a different entity name unless you want to spent some serious time in jail.Should talk to a business attorney.

I am asking because for me it will be almost impossible to get financing in USA, so if I buy, it will almost certain be cash buy.Hope you understand that I am little scared to give someone money "just like that" to invest in real estate.So real question is... are there any real "tools" that can assure money protection or is it all based on trust?

My gut reaction suggests that it may be wisest to hit the foreign market for people who desire asset protection or have some other interest in the area.
