Information asymmetry sometimes defines an entire market (like salaries!). When you take away that asymmetry you change the market.

I don't know if that's a good or a bad thing, but I assume that is what the GP is getting at.

How do you know your house shouldn't be worth even more? I'm not actually saying that it is or should. I don't have a clue where you live or what percentage of the total value 50K is, but that doesn't mean much.
