Payment is usually expected at the end of the inspection unless other arrangements have been made. Usual forms of payment are check or cash. Some inspection companies accept major credit cards. To avoid misunderstandings, ask the inspector beforehand which method of payment is preferred. Most inspection companies will not invoice their fees with the closing because it can be construed as a conflict of interest. Inspection companies should not benefit in any way by a real estate closing. While rare, there are always unscrupulous companies in every industry that may be tempted to gloss over their findings for fear of not getting paid at a later date!
