Rehabber → The word is formed from 'rehab' (short for rehabilitation, which comes from Latin 'rehabilitare', meaning to restore to a good state) and '-er' (meaning a person who). A rehabber is a person who restores something, often referring to properties or items, to a good condition.
Think of someone who is 'restoring' ('rehab') something to a good state, and the '-er' indicates that this person is actively doing that.
