Crowd control is important in any given aspect because of simple reasons: security and safety of all in a given community. There are lots of ways you can control faceless crowd in order to make them very civil and not to create a “mob” with an intention to strike fear and violence. Since you are dealing with mostly rational two-legged creatures, crowd control can be relatively easier if you know the basic ins, outs, tips and tricks of the trade, and the main thing about it is setting a psychological boundary.
Having crowd control within your area will help you when you sell your house privately. Some vendors and traders of their real estate properties are not really into doing serious business in its very sense. As much as possible they look for sure buyers but not really advertise, these individuals can be considered as passive advertisers and if somebody approach them, that will be the time they will entertain these buyers. Another thing how you can sell your house privately is to do it online by posting your property in your social network accounts, pages and the like.
