As Buyer, you will want a fair price, the property to be in good condition, a closing date that you can meet, a way to get our of the deal if your financing blows up and other terms that you may come up with. Expect the Sellers to be clear with their objectives. Generally Sellers will want a fair price, a closing date they can live with and assurances that the sale will close as agreed. 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.

Most individuals who purchase homes finance their purchase. There is a very active market of lending institutions, all of whom are looking for more business. Interest rates and terms vary.
