An inspector checks the safety and condition of your potential new home. Home Inspectors focus especially on the structure, construction, and mechanical systems of the house and will make you aware of possible repairs that are needed.
The Inspector does not evaluate whether or not you’re getting good value for your money. Generally, an inspector checks for: the electrical system, plumbing and waste disposal, the water heater, insulation and Ventilation, the HVAC system, water source and quality, the potential presence of pests, the foundation, doors, windows, ceilings, walls, floors, and roof. Be sure to hire a home inspector that is qualified and experienced. Get references from other people who have used a home inspector.

It’s a good idea to have the home inspection contingent on your written offer.  An inspection clause gives you an “out” on buying the house if serious problems are found or gives you the ability to renegotiate the purchase price if repairs are needed. Part of the home inspection clause can also specify that the seller must fix the problem(s) before you purchase the house.
