I have not seen anyone post about this yet, so I figured I would share some of the highlights after reading the 41 Page Document this weekend  with the new CO Warranty of Habitability Law Updates.I'd like to credit my property manager, @Colin Smith, for updating me and the other owners very promptly and providing a few highlights before diving into the document. 

And at the end of the lease, any bills tied to the house (ie if they don't pay, you have to), get a copy of the final statement to show it was paid in full before you return the deposit.My water company won't let the tenant put the bill in their name, so I send them the bill every 3 months (it is quarterly) and they add it to their rent.When the next tenant goes to move in, get proof that all utilities are in their name before you hand over the keys.
