I'd like to see personal housing moved to its own section and instanced. Like in mist for example, if you run to the end of the beach and go around a boulder or something, it could pop up as a map change area and you could get the apartment options of going to x,y,z house. It would be an entire house, yard and all, with the beach view + water and such, and then make the wards themselves FCs only, as some have suggested. For people who already own personal housing, just transfer their house+yard to the new instanced part, or refund them what they spent on the plot (or give them a small/med/large house certificate or some such, good for one free house in the area of their choice) + all items, so they could then move to a different ward if they wanted to (probably the better option as I know people who have houses in wards they didn't really want because it was that or nothing).

I'm sure some of the people who own a private house will complain, but you can't please everyone. This is the fairest way to my mind for the entire community.
