LLC to buy real estate ?

[Brian Tran]

I am living in Tennessee. But should I create llc in wyoming vs delaware I heard more private for owner to own real estate ? 
second questions : For multi family in LLC company is easy but I am stuck right now with a rental house and I really like to multiply residential properties and get more experience before update Mutifamily apartment . I don't know how to expend my Portfolio with LLC name to own and refinance housing . Should I stop investing in house rental and jump in multi family to qualify for loan also buy under LLC because my debt / income ratio exceed 50%
