As a hobbyist investor, is it worth getting my RE license?

[Chase Petrey]

I am a tech exec who likes to invest in real estate as my primary long term investment strategy. I own 7 units. I find using an agent limiting because:

1. You cannot negotiate yourself but have to have the agent do it
2. It's hard to get a deal when purchasing because of the commission fees
3. Typically pay 1-3% to my agent to sell a property for me (will still need to pay 3% to the buyers agent)

For these reasons I'm considering becoming a licensed agent myself. Any reason why this is a good/bad idea? I have no plans to actually work professionally as an agent. The idea is to just be able to manage my own deals without using an agent.
