but if they aren't working for you, pay someone else

My realtor was never on time to a single showing. He never knew the answer to any question without taking time to look it up himself. He couldn't remember my specifications and his reading comprehension was non-existent as I had to repeat myself many, many times to get any kind of point across.

If I hadn't gotten my house when I did, I would have dropped him. If I were any other kind of business owner and one of my employees acted like that people would think I was a fucking moron for keeping them on.

Your realtor is your employee. Don't be afraid to fire them for shitty performance.
