Master LLC or just separate LLCs

[Chris Hill]

Here is my status

I have 10 properties, two of them recently paid off.  Ultimately I’ll do 10 LLCs for each one, but for now I have started two new ones for the paid off units, and the rest are still in one.

I was told by an attorney to do a master llc with sub LLCs under it. Now, I know what a series LLC is, but have not really heard of a master. Whats the difference? why use it?

If I have them all in separate LLCs and truly run them separate, is there any reason to have series or master LLC? What is the benefit?

Lastly, with separate bank accounts, if I needed to transfer funds around, what is the proper way of doing that? LLC to me, and the man me to different LLC? Never LLC to LLC?
