In Arizona rates will vary from home to home depending upon the square footage and any optional systems the home buyer may want inspected. Beware! Choosing a home inspector based on price alone is a HUGE MISTAKE! Always ask for qualifications, certifications & experience! Home inspectors who charge lower rates do so because they spend much less time inspecting your home either because they have scheduled three or four inspections a day or because they are limited in their inspection knowledge. Why people put their biggest investment at risk over a $25 to $50 price difference hardly make sense to me.
