How many people have multiple houses?

What exactly constitutes an 'unusually high price' to the point it's not allowed and reportable? More than the cost of the plot itself? I'm not being cynical, I'm genuinely curious.

I believe it was left ambiguous on purpose so that the GMs could decide for themselves on a case-by-case basis. I personally report anyone I see charging double or more. There should be a bit of a cushion above the plot price for the permit, irretrievable items, etc. But again, that is my personal feelings, after that it's up to the GMs if they want to take action.
