Do I need to change my business name for funding purposes?

[Zuri Nelson]

Peace, I set up my LLC and it has the words "Real Estate" and "Investments" in it. I was told I shouldn't have put those words in the name for funding purposes. I already got a EIN, logo, business card design, a virtual office etc. all in that name. Do I need to re-register everything , or can I do a DBA? If so, what's some good words to use in the name?
