Any particulars of the form aside, this is just like a regular appraisal; the appraiser is responsible for the comps, analysis, and value. Therefore the discount for not inspecting should not be that large,, IMO. The only difference is now, instead of you inspecting, they sent a nonappraiser out. Now you have your info secondhand.
On the plus side, you will receive extensive photos and some basic notes on materials and appliances present etc, plus a floorplan ( typically)
The form should include a statement that you are not responsible for the inspection, or you can add your own statement.
