Well, on the one hand I would suggest that you trust your realtor. On the other hand, there is convincing evidence, even from realtors, that houses which have a pre-listing home inspection performed have a market advantage:

A pre-listing inspection can help your home sell faster! A pre-listing inspection can maximize the amount that you can get for the home! A pre-listing inspection can give you the peace of mind you need by helping eliminate the element of surprise when the buyer has a home inspection. And a pre-listing inspection gives you the opportunity to resolve issues that you were not aware of before.
