lost families and reverting lots

I can not find my family that was living here. this lot reverted to a vacation rental and it says I cant change it back because it's own.  Correct me if I'm wrong but you can't own vacation rentals.  I cant find how to sell it to change it back nor do I know where my family is off too.  This happens a lot It would be cool if you could own lots but that the family is missing is traumatizing. this happens with other lots too.  Game is in infinite ways broken. I spend all my times trying to fix in in very long loading screens and barely playing. For how no complex the game is,  it really ought to work.
