On a full price contract what happens if a seller refuses to sign

Kathryn, I'll assume from your question that you have submitted a full price offer to purchase a property that is listed for sale. Your "full price contract" is signed by the offeror and presented to the seller as an offer to purchase.  The seller then may accept the offer, reject the offer outright, or return a counter-offer to the offeror.  There is no requirement for the owner to agree to any offer to purchase even if the offer is presented above the asking price. I hope that help, let me know if I can help you in the future.   Donald Eby
