Engage professionals to inspect major components such as the roof, plumbing (including sewer lines), foundation, drainage, electrical systems, HVAC, chillers, boilers, termites, exterior walls, balconies, stairs, rails, and concrete.

In my case, the plumbing inspector was a problem. 

The inspector checks the plumbing and electrical systems, the roof, the foundation, the HVAC system, and the general structural condition.

I would probably choose to do the electrical plumbing first.
