Cohousing-L Mailing List: community approval of new owners/members

[t . lanphar (t.lanphar]

What are some ways that communities have approved/accepted/welcomed new owners? 
 Have any communities required community 'approval' of potential buyers, or 
established voluntary agreements that do that?  If so, what are some legal 
implications?  Cohousing.org FAQs mentions 'right of first refusal' and 
voluntary agreements not to sell to people that won't participate in the 
community.  What are appropriate 'hurdles' for a perspective buyer to get over?

I live in a small (11 household) cohousing community in Northern California and 
we want to preserve our community culture.

Thanks,
Tom
