Our system relies on the buyer's agent to deliver executed contract and addendums to the listing agent, and it requires the listing agent to confirm the delivery of the documents in OfferSubmission.com within 72 hours.
Our system automatically sends an expiration reminder after 48 hours to both agents if documents haven't yet been confirmed received by the listing agent within the OfferSubmission system.
Be sure to follow the instructions as they appear in the email notification you received.
