WHY HAVE AN INSPECTION BEFORE BUYING
Inspecting the physical condition of a house is an important part of the home-buying process and should be included in your purchase contract as a condition of closing the sale. It is important to conduct a home inspection to avoid a costly mistake by purchasing a property in need of major repairs.
A certified home inspector is a professional who will conduct an inspection of the general condition of the home. The inspector you hire should look for:
Defects or malfunctions in the building's structure
Systems and physical components:
Roof
Plumbing
Electrical and heating/cooling systems
Floor surfaces and paint
Windows and doors
Foundation
Detect pest infestations or dry rot and similar damage.
Examine the land around the house for issues concerning grading, drainage, retaining walls, and plants affecting the house.
If the inspection reports show that the house is in good shape, you can proceed with the purchase, knowing that you're getting what you paid for.
If the inspections bring problems you can negotiate to have the seller pay for necessary repairs or to lower the purchase price or you can back out of the deal, assuming your contract is written to allow you to do so.
The inspection process should be one of the contingencies you include in your purchase contract to proctect yourself as a buyer
