Realtors provide a valuable service. We bought in a particularly desirable region in 2021. We put in eight offers before getting one accepted. Our realtor knew the necessary legal forms and requirements, and wrote each offer for us. They also had a background in flipping houses, and were able to give us advice on renovations, and which houses were just bad choices during tours, pointing out flaws we might not have noticed, and telling us when problems were probably easier to fix than we might expect.
Car dealerships are mostly useless. If you've done even cursory research, you probably know more about the car you're buying than the salesperson. Their only purpose is to extract money from you.
They probably got paid ~$50,000 for the service they provided for you. The service may have been valuable, but do you think it was $50,000 valuable? Do you think it should be very difficult to avoid paying that $50,000 if somebody doesn't want the service they provide?
Realtors provide a valuable service, I’ll agree, but I don’t think one in line with the price you’re paying, which is propped up by their cartel system.
