The biggest problem we have with housing is that there's no good gil sinks in FFXIV and it's entirely possible to make millions of gil very quickly because the economy has too much gil in it... which basically means (like others have pointed out) that raffles and houses are going to boil down to whoever has the most gil, or whoever is using RMT to get the most gil. While I would love to see a gil sink, SE needs to figure out a better way to do that with gil or this will be a perpetual problem.
