Make sure the inspector has E&O insurance....actually Mass has to have it.
And get ready for a whirlwind of information. That is ok, take as much as you can, but do not overwhelm yourself. Take a note pad, and do a radon test. It's easy to get scared, take a day or two to think about things after the inspection....we'll be around.
Most of all, have fun on your inspection...it goes down easier.
