This is actually not funny. The house foundation was cracked and an entire colony of garter snakes live in and under the house year round.

If you've been around even one garter snake you know they can really stink. Imagine hundreds. The urine, musk, and feces were penetrating the water pipes causing the faucet water to be comtaminated. You could filter for drinking water but imagine taking showers or baths in that.

The only way to get rid of them would be to tear the house completely down and rebuild for scratch.

So they chose to move because they couldn't afford to rebuild. The same happened to at least one other family after them who weren't told about the snake problem when they bought it.
