Richmond VA Area - Question

[Robert Blazer IV]

Hey there, I'm located in the Richmond VA area, which is where I'm looking to do the majority of my investing for now. I'm very new at this point, so I'm just looking to network with people in, or knowledgeable of the Richmond area. I'm currently inundating myself with the vast wealth of knowledge provided by this site, taking my time to learn prior to jumping into anything.

I have a couple questions about LLCs someone may be able to answer. If the plan is to own 100+ rentals, is it prudent to put them each into their own LLC, or can they be lumped together as maybe 5 homes per LLC? Should the LLC be established in the same state as the rental property (or does it have to be?), and if so/if not, why?

Thanks in advance for any help.
