Company Structure for Rental Business

[Sean Yang]

Hi All, I am a real estate investor located in SoCal. I am just curious to know what company structure do people usually use for buy&hold business? I acquired my first rental unit last year and I am looking to expand my portfolio within the next few years, however, I dont feel it's a good idea to keep everything under my name.. I've read some posts here and looks like most investors use Trust or LLC, and some even use both. What would you recommend? Either way it's going to cost time/money to setup/maintain, and do you think it's worth this effort?
