Co-ownership Vs Co-ops

[BillAlcamo]

Do you know the difference between Co-ownership Vs Co-ops building.

I have been looking into some of these properties and on paper it looks good. I just don`t know why the prices are so low.
Has anyone purchase these types of apartment buildings. What should I be looking for. Should I stay away.

I understand with Condos, you purchase a unit in a building and gain a percentage interest in the common areas. You receive a deed to the unit you have purchased.

With Co-ops, you purchase shares of a private corporation. You do not receive a deed.

With Co-ownership, you can mortgage your interest. Also I read its a hybrid between co-op and condo.

Please advise.

Thanks,
