Does that same logic apply to "buyer agent commission"?

Sometimes a broker will offer a higher commission to tenant rep to get more traffic.

Both things are happening.Buyer agent commission is still negotiated up front with sellers although there is the option not to compensate a buyer's agent - aka have the buyer pay their agent.We also tell buyer's agents to include their commission in the offer.

So the guest is paying a 14.23% commission to Vrbo.

Yes, me too, sellers pay both sides of the commission, but the key is WHO is setting the buyer agent commission amount?

Had our agent break the commission split down.  

Many investors get their license for access to MLS and/or to save money on real estate commissions when they buy & sell.It's a good strategy, but only if you are doing VOLUME!

I had a W2 while working as an agent before transitioning to full time - most folks are in this position.2) You will likely pay your broker a typical commission split even if you are representing yourself.

Real estate commissions have always been negotiable. 

But what is really cool is you can get between 1000-10000 dollars in commissions for signing people up who want to learn about real estate.
