How's that going to find rotting wood underneath the porch or a broken AC?

You know, what inspectors actually do...

Inspectors and appraisers do different jobs - appraisers don't look for rotting wood, sometimes they don't even enter the home (i.e. if they know the trim level used for a particular development)..

Now you are hitting a very interesting idea which would be to standardize home inspection reports in a machine readable format.
