BEST ANSWER. Peter J Roge, Agent, , home inspectors are licensed by the state of New Jersey which should provide you with a measure of assurance. Cost between $400 and $500 They will include a termite inspection that your lender will require and a radon gas test..f you want a high-quality inspection, depending upon square footage of home, you can pay $750 for a thorough inspection. If you figure $750 as a percentage of the purchase price, you know it's next to nothing. Do it right.
