The honest take
Technology assists. Judgment closes the file.
We use AI the way serious practitioners should: to organize data, surface patterns, and speed routine analysis—not to invent a value from a satellite photo alone.
Boots still required
Square footage around obstacles and terraces, plus interior condition, still need a person on site—until robots catch up.

From the field
AI is getting remarkably good at drafting and comparing. It still cannot crawl under a deck, negotiate a locked gate, or explain why that “finished” attic does not count the way a spreadsheet thinks it should.
