WA - Can Managing Broker selling his property independently?

[Alens Fasti]

Hi everyone,

I am qualified to get the managing broker license in WA. However, I am just not sure when I am licensed, will I be able to make transactions myself? Or I still need to hang my license in one of the brokerage houses to do transactions? If that's the case, how much does it cost to maintain the managing broker license in WA? 

I am just trying to save on the commission of my own house transactions so not sure if I should take the exam and get the license yet.

Thanks everyone!
