If you have a 1 500-square-foot house worth $300 000, every square foot in the house is worth $200. If you have a 10 X 10-foot room you can’t get into because of clutter, that’s a $20 000 storage room. In terms of monthly cost, you’re spending about 7% of your mortgage on storage. Are the things in that room worth that much?
Here is the formula:
Total house value /Total square footage = Value of 1 square foot
Square feet of cluttered space (length X width) X Value of 1 square foot = Cost of dysfunctional space
