It still surprises me when I am asked whether it's okay for a client to attend the home inspection!
As a home buyer, it is in your best interest to attend at least some of the inspection. Nothing beats seeing what the inspector sees with your own eyes.
And since I'm on the subject, who are these home inspectors that don't want the client present at the home inspection? All I can guess is that perhaps these inspectors are afraid that the buyer might not be happy with the service they receive if the buyer sees it for themselves!
The moral of the story- Know your home inspector! Just like any other part of the real estate process, you are your own best advocate!
