Separate business account or separate personal account?

[Moises Rafael]

I am in the process of closing on a duplex here soon, also inheriting a tenant so I'm ready for that too, very excited/nervous, I am ready for the ups and downs of managing rentals.

But I was wondering if anyone knew if it would be ok to open up a separate personal checking and savings for the property, since the mortgage is under my name and not an LLC, or should I go ahead and create an LLC to open separate business checking and savings? I hope my question makes sense.

Thank You!
