Even the most experienced homeowner lacks the knowledge and expertise of a professional home inspector. An inspector is familiar with the elements of home construction, proper installation, maintenance and home safety. He or she knows how the home’s systems and components are intended to function together, as well as why they fail. Above all, most buyers find it difficult to remain completely objective and unemotional about the house they really want, and this may have an effect on their judgment. For accurate information, it is best to obtain an impartial, third-party opinion by a professional in the field of home inspection.
