Creating an LLC, and putting existing investment properties under it

[Paul Lim]

Hi all, 

I was hoping I could ask for some advice here. When I first started real estate investing, my mentor told me that I don't have to worry about creating an LLC to start since it'll eat into my cashflow. However, I've been reading how it's just best to be safe. I have 3 properties under my belt, but I haven't created an LLC. I have a couple questions.

- Does anyone know how to properly structure an LLC?  Should I reach out to someone for all this?
- What can I do to put those properties under an LLC? 

Thank you!
