Any Cons to using a DBA 'with' your LLC?

[Jeff Christman]

I am having an attorney set up my first LLC this week. A recent 'get fundable' seminar cautioned about using several "denial trigger words" in your LLC name...words that would get flagged/denied by commercial lending 'automatic approval' software. They were all words you would naturally want to use in your LLC name to describe your rentals business...'properties, holdings, equities', etc. That has me contemplating using a completely generic name for my LLC and then 'adding' a DBA name for marketing purposes. I don't know if this is a viable workaround? If I use the DBA on business cards, tshirts, and on social media, does this in any way diminish the asset protection of the LLC?

To be clear, I WILL have an LLC either way. I just need to decide on the naming approach in the next 48 hours.
