Would you like me to certify that the home? I would discount this as it is probably a sales tool. The question would be what repairs etc did the home maker have to make to get the home certified. My guess is none and they just paid an insurance type company for the certification.
If they had a building inspection company such as you would hire this could be a plus but I would think you would still hire your own inspector.
Try the web site of the realtor to see if they describe the program. Try for a possible example
