This isn't for me. Really. But in a larger sense it may be for all of us.
Does anyone have experience buying a house or apartment with a non-relative on a cooperative basis? Since strong households -- in concert with, but also optionally apart from, families -- can be a protection against poverty and deprivation, I've been thinking about how they can be created. And created on a formal, objective basis if need be.
Cooperatives are a powerful tool, but we commonly think of them beyond the domestic scale. Examples of successful coops include apartment buildings, credit unions, wholesale buyers or rural utilities. Big projects to fund and operate that which might not otherwise be created. Smaller coops -- say, a health food store -- fall into that mixed blessing category: well-loved, but eccentric, difficult and marginal.
I'm thinking of something smaller still. Cooperative arrangements made with a handful of people, are for a limited time period or are organized on an ad-hoc basis. Consider also food buying clubs, pooled lending, tool shares and systems of childcare. (Unitarian fellowships?) I'd like to hear of your successful examples of these. (And if I've piqued your interest, I read about some of these in a book I noted recently.)
