Is 5 units in 1 loan same as multy?

[Al Alfaro]

Interested in a new build building with 5 units originally advertised as a multifamily. After talking to the office, they said these are individual units but that their commercial loan officer can do 1 mortgage that includes all 5 units. Will this have the same tax benefits/consequences as if this was one single address with 5 units? 

Thanks in advance.
