It’s nice to know they need a buyer to be satisfied to help them generate new sales leads, ie. their reputation matters. I still don’t trust these people though. They represent both sides of the transaction, the seller and the buyer. That’s a conflict of interest. Their commission depends on the sale price of the house, which means they want to sell it to you at the highest price possible, so by coincidence they are on the side of the seller and not the buyer.
When you are buying they are like any big ticket sales person. They act like they’re your best friend who is looking out for you, but they’re really trying to get as much money out of you as possible. Don’t trust anything they say. Check everything yourself. Shop around on your own to see what your options are. They will only show you properties they can profit from.
There are a lot of shitty ones put there for sure. I always laugh when I see their bil cards that say something like "I'll sell your house for the most amount of money possible". I just think "why would I ever buy from you then?"
