As a part-time home inspector, you inspect residential properties, usually on behalf of an existing or potential homeowner. Depending on the status of the property, you may also schedule repairs, highlight safety problems, or make recommendations about the site. Home inspections are non-invasive, visual examinations that use engineering principles and an understanding of proper design to find and explain problems. The volume of property sales varies throughout the year, with most sales—and therefore home inspections—done in the summer. Accordingly, many part-time home inspectors work more during the summer and less during other seasons.
