I have heard people pour concrete down the toilet, punch holes in the walls, etc because they are unhappy about leaving.

I got a message from one of them saying that they need to get out of the lease asap - their partner has a temper and has caused damage to the unit, the tenant also sent photos of a hole in the wall, damaged door and trim, and something thrown in the kitchen staining the kitchen cabinets. 

It’s an easy process, but can get pricey based on the depth and what needs to be dug through (and later replaced)There snare companies that do trenchless replacement - basically a hole is dug at the curb and the new pipe is pulled through the old pipe, breaking up the old pipe in the process.

Then I'd unscrew the valves completely so that the tank now has an empty hole where the valve was. 

of course you don't have to divulge your honey holes  LOL 

Punched holes in the vinyl, broke windows, destroyed the crappy plastic gutters.

If you do say yes, it needs to come with monetary conditions.

Just pick a “sold” property so you don’t go down a rabbit hole of “Well if I can just get the $500K property for $400K it works!”

Your savings account wont make holes in your wall.
