Yes you do. A home inspection is basically getting a professional home inspector to determine if you would be getting the worth of your money from the house you chose to buy. The inspector would general check the amenities of the house such as the plumbing system, electrical systems etc. and look for structural problems.
You can call a home inspector after you have made an offer on the house, however, before signing any written offer you should ensure that it includes an inspection clause which says that your purchase obligation is contingent on the findings of a professional home inspector.
A professional inspection will help you make a clear-headed decision.
