Reverse mortgage violations

Someone in my condo complex has a reverse mortgage on his unit which shares a wall with my unit, but has not lived there for over a year and does little to keep it cleaned outside and probably has the heat turned off or down, etc. Which increases my electric bill.

It's my understanding that those mortgages require the owner to live in the home at least six months per year.

Is there any entity with whom to speak with about this apparent violation of the reverse mortgage? We are obviously not privy to her bank or whoever granted this reverse mortgage.
