I charge $295 for single family and I include a free termite inspection. I am also licensed to perform radon and certified to perform mold screenings, if you're concerned about either of those aspects.
-Inspector Mike Savage
at a minimum i would look for someone who is American Society of Home Inspectors (ASHI) certified. past work experience, longevity, and training also matter for something. me, i'd also run them past your attorney as well before hiring anyone (granted that last part is subject to my certain self-interested and self-aggrandizing interests...).
my clients are paying anywhere from $300 to $600 for an inspection of a residential property, depending on the inspector and the property.
price however, is not always a true indicator of quality
Best of luck,

Then I would suggest you DO get a home inspection. They don't just point out the obvious, they also point out the not so obvious.
Good luck with your new home!
