Toth factor

The loss of real estate value caused by a bad, sloppy or lazy neighbor, as compared to comparable homes in the neighborhood that don't abut the bad neighbor. The difference in resale value between a home with good neighbors and a similar one with a bad neighbor.

My nasty neighbors next door kept bothering prospective buyers during showings, so I ended up selling for 20% less than the appraised value. The toth factor cost me thousands!
