disimproved
Declined in quality
Disimproved is the past tense of disimprove, meaning to make or become worse—the opposite of improve.
The word is rare and somewhat awkward, since worsen or deteriorated usually serve better: The property had disimproved under neglectful ownership.
It appears occasionally in legal or administrative contexts discussing declining conditions.
