Owning your own home

What are the thoughts on shared ownership? I have no idea about this i.e. I haven't read a lot into it yet. Is anyone here who is living in shared owned place? What are the cons?

The principal, as you may have heard on the news, is absurd. It raises house prices and benefits only existing home owners and builders.

But if I was a first time buyer who couldn't afford a house I wouldn't be convinced that by boycotting it I could singlehandedly derail the policy, so I'd probably sign up.
