Multiple LLCs or have a parent LLC?

[Victor Genel]

Hello. Need some advice on how to manage multiple LLCs. I want to group my properties by state with different LLC entities for each state. But I want my main entity to be a owner or holding (?) company. Is it worth it the have a parent LLC or keep multiple LLCs? I was understood that having a parent company would make filing easier. Would appreciate any personal experiences. Thank you in advance.
