Entity Formation and Flow of Rent Payments

[Gary Fare]

Thanks in advance to anyone who reads this.  I have read several book regarding this and somewhat understand the overall jist but was curious what everyone else is doing.  

I currently have 3 properties in one LLC (call it LLC A) and am beginning to think down the road in regards to raising money and bigger deals etc. Few questions:

1-Should I be having my tenants make payments to another entity say (Parent Entity LLC) that is not the entity that holds the properties (LLC A)? For example a management/parent company entity or does this open me up for exposure since the lease would be signed with Parent Entity LLC. Or should my tenants make all payments and contract with the LLC A that holds the property and then I subsequently make draws out of there.

2-If i were to raise money under the traditional GP/LP and the GP would be a newly created LLC that I wholly own and I also wanted an equity interest using one of the LPs, should the LP interest be owned by a parent company (Parent Entity LLC) or is it individually myself?

Maybe I am overthinking this but was trying to think in terms of the principles of consolidations and was curious what everyone's experience has been and the flow of funds to legal entities.  Thanks everyone.
