Our board disciplined someone (in addition to other things) for not verifying the data with the county records.
I appraised a home where realist had the lot at 2 acres. Of course, the listing agent used 2 acres. Most appraisers use realist....
This county does not list the lot size for some homes, but does have a measuring tool. So I measured it. It came out to 1.5 acres, so I made the report subject to a survey. Survey said 1.5 acres.
My point is, it has to be 100% all or nothing in this new tech world. Same with regression and other tools.
If we use third party data, measurements, AI to wrangle the data, regression, etc. We should be free of liability from all sources....should not have to verify anything...eventhough the site size was incorrect. If I assume pdc cubicasa measurement is accurate, I can assume all other data sources are accurate.
