As Seller, you will want a fair price, a closing date you can live with, assurances that the sale will close and other terms that you may come up with. Expect the Buyers to be clear with their objectives. Generally Buyers will want a fair price, a property in good condition, a closing date that they can meet and a way to get our of the deal if their financing blows up. The goal of the negotiations should be to maximize the objectives of both parties, not to see who can beat the other side. A starting point for negotiations can be a draft contract, but just because there is a written draft does not mean that the draft cannot be changed.
Word processors are wonderful things and change is mechanically easy to do.
The greatest point of conflict probably will be price. Concentrate on the problem of maximizing objectives and not on personality conflicts. Social skills devoted to avoiding personality conflicts are important skills in negotiations. If there is an important term, put it in writing. As part of the sales process you as the Seller will have to provide the Buyer with certain state and possibly federal disclosures.
