The most popular and frequent type is a pre-purchase inspection. This inspection is typically conducted after a purchase contract is signed and is a part of conditional acceptance of the deal.
The next popular type is seller inspection or pre-listing inspection, conducted when you want to sell your home without unpleasant surprises.
Almost all new home buyers are ordering PDI (Pre-Delivery Inspection), and, consequently, one- and two-year warranty inspections of their new homes.
Maintenance inspection is also highly recommended for all home owners to help them maintain their home in a good working condition.
