Some of the things that you may have to negotiate are:
· The price
· Financing
· Closing costs
· Repairs that need to be done
· Appliances and fixtures
· Landscaping
· Painting
· Occupancy time frame

The key to successful negotiating is keeping in mind that the end result must make both you, the buyer, and the seller happy. Otherwise, negative feelings will persist throughout the remainder of the process and someone may walk away feeling that they were not treated fairly.
