Buying and selling homes is a fun chess game played by the rich. Regular people don't play by the same rules in life, so usually we get pushed out of the market, but sometimes, a regular Schmoe gets the upper hand on the feudal land owners trying to make a quick buck on a short sale.

Neighbors legally have no say on what the folks next door do with their land. So if you're in the midst of a neighborly feud and a grouchy ol' porch surfer is giving you a hard time about your garden decor, you could easily (and legally) say that that's gnome of their business.
