Already there.
my parents live in a 26 home development... there is no HOA... yet no one puts signs up in their lawn, unless its for their kid or for politics... There is ONE house that doesn't do the best on their lawn, and if someone gets pissed, they typically go and talk to the person and offer to do it for them... There is one house that has a few cars in the drive way... you know what people did? the ones who live next to them put up a fence to block their view, the rest just ignore it...
Houses in this development range from probably $250k-$450k depending upon the house...
yet there is no HOA, OMG HOW DO WE SURVIVE
