Hoarding cleanouts are so costly that municipalities can spend $10,000 to $100,000 per incident, and the total U.S. economic burden has climbed past $1 billion each year when you factor in cleanup and lost productivity. When you pair that with neighborhood property value drops of 20% to 30% and the ripple effects on caregivers, landlords, and public health, the impact feels far bigger than a cluttered home.
