I wonder if there are gonna be a house system if so then i got some suggestions.
First of all you should be able to buy houses, there will be some houses that you could buy that has a sign like "For Sale" and maybe it will be able to decay so you must take care of it.
The second is that you can buy furnutures (w/e its spelled) so if you try to put the furniture outside your house area it pops up like this "This aint your property so you cant put it here".
And for the last shinigamis will get their little appartments as in Aizen place when hinamori visits him
