It's okay for the agents to be pushy or the seller to have high expectations. Your anxiety that the deal might not go your way is nothing compared to that experienced by the seller. Powerful feelings can emerge when you visualize yourself and your family in a particular house. Try to resist your fantasies. They will only make you more vulnerable to paying more.
Sellers can smell an eager buyer.
It is strategically wiser to give the impression that you don't really care if you get this house. In truth, there really are many more houses out there. If you don't get this one, you'll find another - possibly better one. Beware of pressure Even if you resist falling in love with the house, you can still be influenced by pressure to increase your price beyond that which you are willing to pay. Pressure is part of the negotiation game.
