It's not really whether you notice it or not its the disclosure you make, you should never make a statement about something you don't know anything about.

In my own experience the Realtor mediator would likely split the fee, but I know we are far from getting all of the info on the issue so there are many other variable but from the info you have given its pretty easy.

However a leak in the water line technically makes the water undrinkable due to contamination which makes the house inhabitable and list goes on.
