Counter Offer to Purchase 3 - Residential: A Counter Offer is used when the Purchaser and Seller are attempting to reach an acceptable price to both parties. The Purchaser offers an amount for the property in question; the Seller then gives this counter offer which states that he/she accepts the Purchaser's offer with an exception. If the Purchaser agrees to the exception, or counter offer, then he/she must sign the document in front of a Notary Public to accept. This form is available in both Word and Rich Text formats.
