If I assume that everything you say is true, doesn't it mean that farangs need to avoid trouble in LOS.
Had they rented and had a problem with scum neighbours, then they could just move, but oh no, they had to go all too posh to rent and buy an expensive house, which IMO was their first mistake. Then they made more mistakes. Farangs should learn more about the culture they want to live in before making expensive mistakes.
