Does anyone have any knowledge on whether I can represent myself in a transaction with a builder on the purchase of a new construction home for myself as an actively licensed broker in WA Seattle area and collect or save on the commission myself?  

Being a native here in Washington DC. 

He's still able to commute to his job in DC (the drive is actually a bit shorter now!)

Actually you can make any market, okay almost any market except CA, NY, WA, IL that type of market is very tough to cash flow, but for AZ, TX, FL, GA, NC, you can make those markets cash flow.

I am a real estate agent that specialized with the Washington Team Realty located in Columbia, MD.

I have equity in my property which is in Washington state, and I'm interested in finding an investor who would be interested in loaning me 20k to 30k in exchange for an agreed percentage rate when the house sells (within 10 years).

They only lend in OR, TX, and WA and you must be experienced.Cheers!

In Washington state they also tie Electricity on the landlord, regardless of name on account.

Inland Washington is much better. 

They have to populate the card with either cash or CC/DC, and then once it's on the card, they use it to start the machine.
