You don't have to pay anyone to sell your house, you can sell it yourself and lot of people do so, sucessfully.
If you want free access to the system that, between license fees, insurance, ongoing (required) education, and CMLS subcription fees cost me about $1500 a year, think again.......
$1500 would be a great bargin compared to 6% on most home sales.
Who said anything about free?
I am pointing out that's it's a closed system. Paying for access would be worth it to me. But not thousands of dollars. And, since you are spending money to make money why the gripe?
