Personally, I would like there to be things to do in your house, because if it is only going to be a showcase to look at, it would be boring for me.
I would do something like being able to grow plants from which to obtain resources for crafting, raising mounts or something that was very cool about an MMO called Wildstar, that every so often your house had a small "plague" of enemies (zombies, beasts, thieves, etc. ) and that it is your turn to clean. Of course you would get some loot from them
