You always should use a Licensed Home Inspector and one that is a member of ASHI....the
American Society of Home Inspectors. People think that a license is enough, but I find the ASHI seal is what sets him apart. Also, a home inspector that is a Structural Engineer is a plus because if there are any structural issues, he can find them without the homeowner contracting a structural engineer after the inspection to inspect for structural issues. He's all in one!
