Gil sinks

[ItMe]

25 million gil/month rent for a large house
10 million gil/month rent for a medium house
1.5 million gil/month rent for a small house

I pay my sub to play the game, not to spend my time on upkeep.
How am I supposed to make this kind of money if I'm mainly a raider? Or if I'm mainly here for the story?
All this'll do is encourage more RMTing.
