That was a good attempt to try to show how much work is involved, but most of that stuff involves a phone call or filling out a form. Perhaps 3 hours of work. The benefit of listing is to get access to all the buyers who use realtors. There is still a majority of people whose mentality is they need a realtor.
LOL. I suppose if you have the only house for sale, and you're selling it "as is", and you have a line of buyers desperately bidding up the price, you can just "fill out a form" and rake in the dough. Makes it real easy. Funny how that doesn't seem to happen very often.
