Buying rental properties - Individual or LLC ??

[Paul Greenberg]

I'm ready to dive in to rental property purchases in Palm Beach County, FL. Will be doing so with a family member and I don't know whose name(s) the property should be under, whose name(s) the bank accounts should be under, etc. 

If one partner is a 50-something and the other is 19 years old, would we refinance individually or under an LLC ?

Lots of questions, looking for an advisor.

Thanks in advance
