Should I open a DBA?

[Adrian Vega]

Hello,

I purchased a single family home 4 years ago and just recently moved out and now owner occupying a 3 family. I rent out the SFH and also have 2 tenants on the 2nd and 3rd floor of the 3 family and I'm on the 1st floor. My question is since I have done this with out a LLC and am a sole proprietor is it worth creating a DBA? Are there any tax benefits in doing so? I plan to purchase another property in the future thru a LLC but might not be for awhile. I know liability is a issue being a sole proprietor but curious on if it's worth getting a business certificate from the city or just continue to do what I am doing. I do also have a separate personal account that I only use for the rentals.

Any help would be appreciated.
