DBA or LLC

[Greta Clav]

Hi everyone. With my past rental properties I never created a DBA nor an LLC and thankfully everything worked out fine. Fast forward to today, I currently have 3 properties and I will be inheriting 10 additional ones (4 SFR and 6 multi-family). I know my way around with the purchasing and financing options/process for properties held as an individual, but I am ignorant as to how it all works if commercial. Given my experience , or lack of, and the number of properties, what is your recommendation on me establishing or not a DBA or LLC?
