Next time they flip out, tell them it's not like you're charging $15,000 to put a sign in the yard and show people the house when they call until it sells.
We flipped a house several years ago, they put the sign in the yard on Saturday, did an open house on Sunday, had the signed contract on Sunday night. They made $12,000 on that house and spent 5 hours on the job.
I think $25 for a rider is a little less profitable then their chosen career.
