"As a realtor, you get a huge, immediate payoff when the house sells.""immediate", except for the fact that you might have been working to find or sell the house for a year, and months to put the deal together.
This is assuming the house ever does sell at all, and you haven't worked for months or years to get absolutely nothing.
And it assumes that if the house sells you don't get cheated by your client and actually do get paid.
"You don't care about the price."
Except that usually real estate agents get a percentage of the sale price as commission.
Real estate agents also want to make their client happy so that they'll get recommendations and referrals from them in the future, and want to work with that agent again when they look to buy or sell another home.
