^^Yeah, but he has to split the commission with his "house", probably 60/40, so he'll really pocket around $15,000...before taxes, of course. So he'll have to sell a LOT of very expensive houses to make a comfortable living. I don't really know the RE market in Vermont, but Cali is the most overpriced state, and you can routinely get single homes in the range of half a million. Some of the condos I've been looking at are around $400,000.
Of course, commissions are higher on lower priced homes, but even if you're a fully-licensed broker, you'll be making 6%, tops (unless you're both the buyer and the seller's broker, of course). That means on a $400,000 home you'll work 7 days a week to get it sold, and pocket around $24k. However, it seems our resident garden gnome is a salesman, which means the .75% is about right. That means a sale like the one I described will gross a whopping $3,000...which he'll have to split 60/40 with his "house".
And don't even get me started on the whole "independent contractor" aspect vis-a-vis income taxes.
The bottom line is, you gotta sell a helluva lot more than 6-7 houses a year if you want to make any money.
