There is no requirement in the State of Idaho that a Seller inspect a property prior to selling or a buyer inspect prior to purchasing.
It is, however, highly recommended you hire a professional inspector to conduct a thorough professional inspection.
You can conduct the inspection by yourself, you can hire a contractor OR you can hire a professional home inspection company.
Below are several inspectors we've used in the past with good results. Each inspector offers slightly different services, so it's important to call and find one that suits your needs.
