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!
