Which particular property are you referring to? Policy regarding sublet differs from co-op to co-op. Some allow it and some do not. The ones that do allow it usually want the tenant to be approved by the board. In addition, here in Brooklyn, although some do allow sublet, restrict the owner from subletting in the first 2-3 years of ownership. You have to check with the co-ops management company to be sure especially if subletting is a concern for you.
If I can be of further assistance, please let me know. Good luck!
