Most importantly you should look for the proprietary lease expiration date. The lease term must exceed the term of any proposed or anticipated financing, otherwise you're going to have serious difficulty in obtaining a loan from a bank.
However, it's my understanding that most co op boards in NYC will issue a letter saying that they intend to extend the proprietary lease.
You should always also review the rules with respect to assignment or sublease, which may appear in the proprietary lease. Consent by the coop board is usually required unless the transfer is to an immediate family member or due to death.
You should also check whether the building has a flip tax or any fees or assigning a lease and for subletting.
Anything else that I'm missing?
