There's also an interesting aspect to a realtor that fills a guiding role. They're the person who helps turn seemingly intangible preferences into tangible search criteria (which can be executed by either party on mostly-public databases).

In fact, in the long-term, as jobs are automated, I'd expect people to spend more time, not less, on taste clarification. Then the pattern is to think about how all guiding roles in society will form to tools that automate the simple bits and let humans spend time doing what they do best. Imagine how much better it would be as a realtor to spend time in conversations inside virtual homes rather than sitting in traffic, navigating database searches, or fiddling calendars.
