Creative use of CMX-2 duplex & is a balcony a liability?

[Lana Lee]

Closing on a CMX-2 zoned duplex in Philadelphia soon. It has 2 residential apartments and 2 very large rooms with locks in a basement. Would like to know what can we do with this space in the basement? How do we advertise the appartments? What those rooms can be used for?

Also, there is a large balcony for the second floor apartment which is accessible only from the common area. My husband wants to just close it down, he is afraid of the liability. Do you think balcony is a plus or a liability and how to protect ourselves from the liability point of view aside from keeping it in good safe condition?
