Comparable sales information helps you to determine a base price range for a particular home. Adding in the various factors like property condition, improvements, market conditions, and seller motivation help determine whether a "fair" price would be at the upper limit of that range or the lower limit. Perhaps you will feel a fair price is outside of that price range.

The "fair" price should be approximately what you are willing to agree on at the end of negotiations with the seller. The price you put in your offer to begin negotiations is totally up to you and depends on your negotiating style. Most buyers start off somewhat lower than the price they eventually want to pay.
