The marketing makes lots of promises with cohousing but there is only one guarantee- you get a house. You buy it or rent it, but that’s the only thing for sure.

Other things you will probably get:

HOA membership/fees. They expect participation in governance and helping to maintain the property but how to “enforce” that is questionable. Yet, most go in wanting to participate.

You MAY get a common house but not all places have built it yet, or it is falling apart, or is still in budget talks, etc.

You will probably have some sort of common gardening area and then each place negotaites on the water bill and taking care of the plots.

You may also get a pool, trampoline, and/or playground.  

You may also get a workshop, gym, yoga space.

It all depends on how the communities negotiated common space and budgeted.  

It’s all about group decisions.

So, you may get friends, you may just have friendly neighbors.  You may love it, you might not. But the only thing for sure is that you will be able to live in a house/unit.  (that’s another thing, they really prefer you odn’t buy in as an investment property to rent out or only stay half the year).

I wish I had more realistic expectations. Good luck!
