I am a new Realtor (SoCal) and I'm doing my first open house today.

My mentor sent me a pre-filled BRBC at 2.5% and told me this:

As they walk in, introduce yourself, thank them for coming and ask if they are currently being represented by an agent.  If yes, let them know you cannot discuss details of the home to them other than what's on the flyer and that they're required to sign in on the sign in sheet and provide their agent's name. If the answer is no then say, I'm sure you've heard about the changes going on with agents and how commission is handled but if you haven't ... agents are now required to get a document called the BRBC signed before performing any duties considered acting in real estate.  This includes showing around an open house. I joke with them and say, yeah I know it's silly but before I can walk you around, I'll need you to sign this BRBC.  Should you choose to buy this home ... and only this home, I'd be representing you on the purchase.  You're not required to use me on any other home at any other time.  It's literally just for viewing and representing on this home.

I pushed back on this, telling my mentor:

What if I don't push the BRBC on people as soon as they walk in? Or, I present them with both that form and the OHNA-SI [note for those unaware: this is a new form CAR has made available as of August, the "Open House Visitor Non-Agency Disclosure and Sign In"] and explain what both of them are, and let them choose if they want to sign either? It feels like a bridge too far to ask people to agree to pay me commission just because I happened to be the one to let them in the house. Yes, I get it, it's just for this property, but still. If this is the property they bid on, and their bid is accepted, it's the only property that matters. I understand why it benefits me to get them to sign the BRBC right away. But I'm less convinced it benefits them. Except to the extent that I know I am awesome and will represent their interests fiercely...but they don't know that. They just met me

My mentor replied:

You don't have a choice unless you tell them you cannot talk to them about the home.  You cannot say a word outside of what's on the flyer literally.   

To which I said:

Then what's the point of the Open House Visitor Non-Agency Disclosure and Sign In form? But also... I'm fine with not saying a word outside of what's on the flyer literally.  The BRBC is 13 (!) pages long—I am literally LOLing at the notion of asking someone I just met to sign this! Like, it's sincerely funny to me.

To which they said:

This was 12 hours ago, I haven't heard boo from them since, and the open house is today.

Can I get a r/Realtors community vibe check on this? I'm open to hearing why I'm wrong, if I'm wrong.

Thanks!
