Luxurious housing is something that will likely not be seen on a space station, not from outward appearances anyway. There simply wil not be enough space for huge luxury houses. In fact, it is more likely that the housing situation would more closely resemble the quarters on the starship enterprise.
I disagree with you when you say housing is a privilege and not a right, everyone has a right to have a roof over their heads. Sure, keeping that roof comes with responsibilities but, the responsibilities do not come first. They can't come first, especially if they require one to already be living there before they have any validity! Also, the idea of proper neighborly behavior is subjective and can not clearly be defined. So, who's opinion of what is proper neighborly behavior could we possibly form that rule around? I mean, daily interaction with the neighbors could by some be seen as proper, while others may think that not having any interactions with the neighbors is fine as long as no trouble is being caused.
I myself am not what you would call a social butterfly and as a result would interact with my neighbors very rarely as I do now. To some that is seen as anti social behavior and could be considered as not very neighborly, however, I am not anti social, I have just never been much for socializing especially with folks I do not know. Then you have to consider the social climate, some times you run into trouble just by trying to be social. In all reality there is no thing as proper neighborly behavior. If people are not causing any trouble isn't that all that matters?
