Property Inspection Question

[Paul Altman]

Hello

When having a property inspected is it recommended to use an actual licensed inspector to prevent any inspection clause issues if the seller tried to claim the inspection wasn't reasonably performed or will i be fine with just having a contractor look through? Or can i just do nothing at all and simply say i didn't like something about the house? Do i even have to provide a reason for wanting to back out or can I just say I wasn't satisfied?

Have heard mention of sellers trying to force buyers to buy based off the claim of "unreasonable dissatisfaction of property condition due to insignificant repairs" or that the inspection wasn't performed by a qualified professional.     

Thanks
