So I've been busy the past week or so due to college and when I read the Shirogane info I was confused.

When purchasing a plot for relocation, 30% of the minimum value of your old plot will be applied towards the price of the new one.

(Cost of Relocation) = (Destination Plot Price) – (30% of Old Plot Price)

* In the event reimbursement for the old plot exceeds the price of the destination plot, the cost of relocation will be waived. Please note, however, you will not receive gil for the amount that exceeds the cost of the destination plot.

Does this mean I have to pay more than 20 million for a relocation of a medium house to a medium house? Clearing this up would be of great help. I'm tired so I may just be reading it wrong.
