What I meant is this:
$150,000 is "gross" selling price
If seller pays 6% brokerage fee, they net out $141,000 before all of the other deductions that result in their equity plummeting :-/
Let's say Broker A is selling your property and is approached by Broker B to purchase. You will still have to pay 3% of the selling price to Broker A, but since Broker B is effectively the "buyer's broker", they are also due 3% of the commission. But since they are buying it, they choose not to receive a commission, but rather to buy the home for 97% of what the market value or original agreed-upon selling price is ($150,000).
I did this on my first house-my father has a broker's license and he acted as my broker. Instead of obtaining a 3% commission, we just knocked the price down to 97% of what was originally agreed upon. The seller of that home was indifferent to that.
