Do realtors have to disclose they are licensed when purchasing a rental for their personal portfolio?

[Kyle Grimm]

(Located in Missouri) My question is, do realtors always have to disclose they are licensed even when they are buying for their own personal portfolio? I am planning on getting my license but am wondering if it could be a downfall to some awesome deals once they find out I am a realtor.  For instance, yesterday I got a lead on a vacant duplex and found out the owner was retired and didn't want anything to do with it.  He mentioned a price I know was well below it's value.  But then with suspicion in his voice he said "you aren't a broker are you?" as if he wouldn't have sold to me if I was.  Any input would be appreciated!

In probably every state, you have to disclose.  Here, it's prior to any negotiations.
