Cm-I am a licensed Realtor in GA and I am not familiar with CA real estate practices; however, for what it's worth to you, most offers will have a time limit. Therefore, time is of the essence and it is incumbent upon me to timely present all offers (written or verbal) to my client.
I typically alert my seller clients by phone just as soon as I learn that an offer may be presented or once one is received by my office. Then, I schedule an appointment to meet with them to go over the offer in-person or, in some cases, I fax the offer over to their office or home and we discuss it over the phone. In some cases, there may be multiple offers coming in. In such instances, with my seller's consent, I notify all bidders of such fact and specify a time that we will present all of the offers. This allows my seller client time to review & consider each offer as well as solicit highest & best offers from all bidders.
Did you present an offer and have not heard anything back from the seller's Realtor? Do you have a buyer's agent representing you and you alone in the transaction? Did your offer contain a time limit? Regardless, I wish you the best of luck obtaining a prompt answer on your offer.
