The appraisal probably won't be used by the mortgage company who will want to have their own appraisal, but I'm not an expert at that.
You need to find an objective inspector to do the inspection before moving forward on this. It is such a conflict of interests for the agent, who wants to close the deal without hitches, to choose the inspection company without your consent. I believe it is called "steering".
There are inspectors who do cursory inspections to help make the home look good for selling. Get more information about this, and choosing a home inspector at my website : http://www.BuyersProtectionService.com/ChoosingInspector
