In exchange you would partner up on all the wholesales and provide access to your cash buyers list as well as get first look at any deals! 

Starting with a commercial property (5+ units) will be pretty tough.Factor in you'll need 35% down payment in addition to a ton of other closing costs.

Is it generally understood that in-order to get a pocket listing from a *commercial* multi-family broker, you will have that same broker represent both sides of the transaction (i.e. there is no additional "buying agent" involved?)

If the realtor is just representing the buyer, then she should not have had access to the actual dollar amount of previous offers.   

That amount of money will also buy you a nice commercial multi-family 10-14 units maybe more or less.

Similar results can be anticipated if you "squat" in a parking space that is not yours.Renting a parking space is a commercial lease and would fall outside residential tenancy law.  

I am looking for a commercial real estate broker to help me with multi-family (more than 5 units) in Pierce County.

I am former AD Marine getting into commercial real estate.

They are just a broker and use First American Commercial Organization. 

With many commercial deals requiring even more to hit the magic 1.2 DSCR in this heavy sellers market.
