A inspection gives the buyer an unbiased review of the overall condition of the home.  While assumable properties do not require an inspection prior to purchase, doing this beforehand does provide protection. The primary objective is to take an in-depth visual examination of the physical condition, structure, equipment, finishes, and mechanical systems. Depending on your location as well as the size of the house a inspection cost on average $300-$400.  But if you really want to save, there are ways to do it yourself.
