As everyone else says - no Realtor, no Commission! If you and your partner were to go ahead and list the home for sale, then you would be signing a listing agreement with whatever Realtor was involved, or if you are selling FSBO and your ulitmate buyer has a Realtor, you may have to pay a commission to the Realtor working with the buyer (depending upon the contract). If you listed the home with a Realtor, the commission would be agreed to at the time of listing with the Realtor and the commission would be deducted from your proceeds at closing, then whatever is left over after paying the costs of sale would be paid to you and your partner. But if your partner is simply buying you out and you have no Realtor involved, then you do not have a commission to pay. You should, however, consult an attorney to make sure you are protected in this transaction. Good luck!
