Remember that in this type of situation you will be dealing with the actual owner of the property. Do not insult the owner with negative comments when looking at the home. Even if the cat box is stinky or the garbage needs to go out, do not comment. Keeping the seller on your side is important in a for sale by owner deal.
Mind your manners. Negotiations can be frustrating, but they are no place to lose your temper or cool. If things get too heated, ask for a ten-minute break to cool the tension.
For buyers who want to negotiate in a for sale by owner sale, it is best to remind the seller that he or she is already saving at least 6% in real estate commissions so there should be room to negotiate. As in every real estate deal, do not take it personally if the seller refuses to drop the price.
Before going into the negotiation, do your homework. Gather evidence of similar homes in the area that have sold recently, the comparables. Decide exactly how high you will go. If the seller will not come down to a dollar amount that you can handle, stop the negotiations, thank the seller for his or her time, and go on looking for a home that is in your price range. Do not let the excitement of negotiating push you into a purchase that you cannot afford.
