Good points, waffles and Jules. The 'ripple effect' of hoarding individuals is possibly more heartbreaking.
Family members are close to helpless in dealing with the mental illness, the hazardous conditions, and the property damage that is done. When hoarders live in rented property, property owners must go through a long, arduous legal process to get evictions approved and served. Then the property owner is left with the bill for repairing damage done by pets, vermin, and plain old mold and rot.
If you happen to share a wall or your ceiling is a hoarder's floor, it can be catastrophic. Pipes burst, sewage overflows, pests and vermin come out of the walls. Then there's the smell. Hoarding can lower property values once discovered.
It's like you know a volcano is exploding, but it's a slow exploding type, and trying to protect yourself and your property is a very steep, uphill, and expensive battle.
It's a nightmare you almost can't wake up from.
