LLC: Form now or in 2017?

[Mark S.]

Looking to start investing in January, 2017 in buy-and-hold rentals with an investor group. I want to create my own LLC which will buy into the LLC that owns each property. I'm looking for form LLC in Kentucky. A few questions: 1.) Does it matter if I do it now or should I wait two months (to avoid any annual fees, etc.)? 2.) This would be a single member LLC. Should I still use an attorney, or would an online service like LegalZoom likely suffice? 3.) Is it worth the expense of renting a UPS mailbox for privacy? Does it matter that your name/address have to be disclosed on original paperwork? Thanks in advance.
