re: Any real estate investors?

Regardless of what entity you choose, there is no substitution for paying for the proper amount of insurance. No entity can shield an individual from liability if such things as disregard of safety factors, an individual's actions causing bodily harm to another, etc..

Whatever entity you set up, remember to strictly follow proper procedures for such entity and purchase a sufficient amount of insurance! Insurance is the key for protection from liability regardless of the entity chosen for tax purposes.
