Why do you need a home inspection?
Who else in the neighborhood is looking out for your interest? Is the real estate agent, (who gets paid only if you buy the house) able to be totally objective?
Often, sellers are unaware of defects needing repair in their own homes. The home inspector should impartially and objectively evaluate the following: roof, condition, structure, plumbing, water pressure and hot water tank, foundation, basement leaks, electrical system, insulation and boiler/furnace (and whether or not it’s leaking carbon monoxide). While the home inspector can’t determine if the heat is evenly distributed or adequate, his report will indicate whether any rooms lack a heat source (yes, it happens).
Just remember that even if the home inspector finds a lot of things in disrepair, almost everything can be fixed.
