Phillip & Jeffery have given you the best reason, by law you represent the seller if they do not sign. Your job if they choose not to sign is to unlock the door, turn on the lights, lock the door and represent the interest of the SELLER! If they buyer asks questions of you such as what do you think about the condition of the roof, carpet, ectâ€¦ or do you think if we offered x amount to start with then we could take it up to y amount if it was rejected, you are obligated to pass the information along to your client aka the â€œsellerâ€. If I was a buyer and someone took the time to explain the law to me I would have no trouble signing, I think the problem is Realtors try to lock someone in for 90-180 days that they just meet, my solution is a 1 day buyers agency agreement for the properties shown that day. If they want to continue working together after day 1 I usually ask for 90-180 day commitments which I would let them out of at any time as long as it was not for the purchase of a property I had previously shown.
