What qualities to look for in a good agent? Trying to learn as a new agent

[Casi Rice]

I am in no way asking for business but rather for your opinions, thank you! 

My question: When you are looking for an agent to work with, what are qualities you look for and want? I ask because I would like to work with investors but I would like to understand how to be an asset when that time does come. 

Background: I am a real estate agent with property management experience. I would like to invest in the future but no deals under my belt. I have been a homeowner before and flipped my house, but that was because I love projects. 

Thanks in advance for your opinions!
