You are grossly underestimating the things I will do for a client. I've shown houses on holidays, measured and filmed everything under the sun, crawled through muddy bug-filled cellars; the difference between a good agent and an average agent is even higher than the difference in 10x programmers.
I, like many of the other people in this thread, had a buyer agent that did nothing. If you need someone who can do these things, looks like you've found that person!
So the value prop is that you’ve built a service that does the same job as a lazy buyer’s agent? If I’m paying someone to help me buy a house, they better be Johnny on the spot handling my requests, which include measuring a room or advising if something was installed properly or not. If they can’t do basic things like that they are useless to me.
