Local trade and NAR (national association of realtors) magazines are wonderful as well to help keep you up on your city. 

Obviously the Selling Agent does not Represent me - They represent the Seller but there are Ethics Clauses in the NAR that state an agent must be honest with all parties including the other side.

The more you buy/sell, the higher % you keep, depending on your contract with your broker.You're probably best off at a small local firm where you can pay minimal fees, get access to MLS and basic supervision, and aren't required to pay $600/year to local/state/national association of realtors (NAR).

Also, does NAR, or any other state have laws regarding agents and brokers carrying?  

Since 2013 I am no longer doing much in terms of acquisitions so I did not renew my membership with NAR, CAR, and my local association.  

I will admit that I don't like how the NAR has a stranglehold on the MLS.

Did you know that the NAR is the second largest lobbying organization, by dollars spent, in this country? 

I think it has merit and potential.Remember for real estate agents when NAR would send a letter and you electronically sign and then tens of thousands of letters go to Congress etc on a specific issue NAR is fighting?

You guys seem to be putting a lot of faith in NAR and the political process that keeps agents in place.

If you don´t have access to Costar, you can also search "NAR commercial report" > your state> find the MSA.
