I don't like the idea of having to pay $400 each month just to prevent your house from being sold with no refund. There was a lot of cases in which players simply had to go inactive for a certain period of time. Would be kinda unfair towards them, and admit it, maintaining such a topic would be a hell of a work.
For the passport details, I wouldn't really mind that, but it might get annoying once you decide to roleplay a different character, for example. Nothing ruins roleplay more than roleplaying the character of Hercule Poirot and getting arrested for having a passport belonging to Sherlolck Holmes. Also hookers with
Sex: male and
Age: 15 wouldn't be so attractive.

In addition to that, COL staff and administration team members already have a load of work and renewing multiple passports and being asked to change this or that would certainly not make them happy. Maybe if those 400 bucks went into their pockets...
