New Agent with a couple questions for the seasoned professionals

[Christi Nicolet]

Hello Bigger Pockets community! 

I just received my real estate license in Massachusetts and plan on attaining my New Hampshire license soon, since I live right on the boarder of MA and NH. I was wanting to get some advice from those within the Bigger Pockets community since most real estate agent education is focused around helping people purchase primary residents. 
I'm more interested in helping investors as my niche and would love to hear from both agents and investors on a couple questions.

Agents:
1. As I am interviewing brokerages, with the goal of being investor focused, what questions should I be asking?

2. What do you suggest for resources (besides Bigger Pockets) on being an investor friendly agent?

Investors:
1. When looking to add an agent to your team, what do you look for? 

2. What would an "ideal" agent look like to you? 

I look forward to reading your responses and feel free to add any other advice you wish you would have known when you were first getting started (as and agent).
