New Investor: should I form an LLC or get DBA?

[LaRhonda M]

I am a new real estate investor starting in primarily wholesaling. (Working on the marketing of my business as a wholesaler as of now.)
I'd like to use a professional name/ business name to put on my business cards, websites, etc. I think that would def give a little more credibility rather than operating as an individual... Would you guys suggest to form an LLC which I've noticed many do, or would a DBA be enough??...and what are the pros and cons?

I’d also like to form and use a name no one has or can use, and continue to use this title as I venture into other areas of real estate investing in the future. What are your suggestions?
