How to approach to start a business company for investment?

[Davey Davanoski]

I have some many questions, but instead of spamming the forums, i decided to go with this universal question as a title.

I am learning so much from this site about real estate investing. But i still don't understand 1% of real estate and how does work anything, but i will get there, hopefully.

Before i start with endless questions, i will write, right of the bat, that my goal and desire, is to invest, buy/hold in rental properties, (residential), long term.

So. Questions.

Q.1:When planning to invest in a rental building and buy it. Do i need to have LLC entity before i buy/invest in rental buildings, instead of having in my name?

Q.2:When is time  to invest in more rental buildings, and i have previous only one. 

- Do i need to register again LLC for different rentals?

- Can i have all rental in one LLC entity?

- Is it possible to create a entity, that holds all LLC in one name but, still be separated from each other? Like something to hold all those rentals under one roof?
