You've sought out an agent to work off market deals for you (ethical red flag and possibly not legal for an agent to do according to NAR), then they BROUGHT YOU A GREAT DEAL, and now you're concerned that they might have a motive other than your benefit?

The broker is very interested in not getting sued and this agent is setting him up for a big mess of a court case and fines from the state and maybe NAR and/or the local MLS board.Your PA agent can submit an offer in NJ only if he's licensed in NJ.BTW, even if the other party "accepted" your offer, it's still invalid without your signature. 

I take what NAR says with a grain of salt because no one accurately predict what will happen until they know the national economic and social policies that will clearly have an impact real estate. 

However, I'm not sure you can get around paying the NAR and local association dues, and the MLS fees.  

Activly contact and support legislatures, NAR, your local REIA groups, to be vocal, active and apply pressure to do the right thing.

There are TREC, TXR, NAR, TAR, etc.

Must I be a member of NAR, CAR or a local board in order to collect a commission in this scenario?

NAR is comprised of MLS systems nationwide, each with their own rules and regulations.   

You must disclose your an agent when buying or selling you have to conduct your business and personal life according to the people who run NAR and today I read they just came out and said they’ll be watching your social media censoring you Anybody can get access to the mls or the ability to view a house on the market .

They may not be a member of NAR and this doesn't exactly fit this situation exactly but I'm sure the their broker and state would agree that their behavior was unethical and unprofessional.
