Follow up negotiations may be necessary during your offer consideration period. The seller could take a number of steps in response to your offer, such as: Accept it AS IS, reject it AS IS, counter specific changes to the offer, counter multiple offers with the same or different changes to each offer.
Each contract and offer is different. Deal points will take into consideration both parties financial positions, diligence in investigation of the property, timing of the escrow and moving necessities.
Once both parties are able to find common ground on deal points and the offer is fully accepted and executed, it will be time to open escrow.
