Negotiating the price of a home is a double edged sword... If you pay to much, you're over paying, but that could create a positive trend for the neighborhood. If you pay to little, it can result in a negative trend for the neighborhood. The goal should be to purchase the home for it's market value. To determine it's value, you should employ the services of an experienced realtor or appraiser. These professionals will be able to help you determine the value of the home in comparison to other homes that have sold in the area and identify the current trends for the market.
