Kevin is right, you need to check with your state and what they require. Most banks will require an NPMA-33 form for VA/FHA/HUD/USAA loans. Check with your state regs to see who can fill out that form. In NY you need to be Commercial Pesticide Technician or Applicator to fill it out. Any home inspector can do a WDI inspection, but only a Technician or Applicator can sign the form.
