Can you trust AI with a land appraisal?

Here is the honest answer most AI companies will not give you: not blindly, no. And if a vendor tells you their AI just does your appraisals and you can stop checking, walk away. That is not how you should use it, and it is not how we built Harold.

The worry behind the question is sound. General AI does make things up. Ask ChatGPT for a land appraisal and it will hand you a confident-looking number built on assumptions you cannot see. For a figure that decides whether you chase a site or let it go, a confident guess is worse than no answer at all.

So the question is not really "is AI clever enough to do an appraisal." It is "can I check what it did." That is the line between a tool you can trust and one you cannot.

Trust the working, not the output

A trustworthy appraisal is built from inputs you can see and change. Your assumptions, your comps, your method, every line visible. You adjust what you disagree with, and you keep the final call. The tool does the assembly. You do the judgement.

A number that appears with no working behind it is the opposite. You cannot check it, so you either trust it on faith, which you should not, or you rebuild it yourself, which means it saved you nothing.

Why "trained on your deals" matters here

An appraisal built from how your firm actually prices is checkable against your own instinct. You look at it and you know whether it feels right, because it was built on your logic. An appraisal built from generic web data is not checkable in the same way, because you have no idea where the numbers came from or whether they apply to your market.

That is the real difference. You are not being asked to trust the AI. You are trusting your own inputs, assembled in minutes instead of a morning.

What that gets you

The appraisal that used to eat a morning takes minutes, and you spend the time you saved on the read that actually matters: is this a site worth fighting for. You move on it faster, with a number you can stand behind because you can see exactly how it was built.

That is the test for any AI you let near a real decision. It should show you both the answer and the working. One that does has earned a place in your week. One that asks you to take its word has not.
