Things to Look for When Buying a Brownstone

I am a potential first-time brownstone buyer and am coming from a highrise coop, so I do not know how to assess brownstones. Aside from a schedule of major maintenance performed (rood, boiler etc), monthly utilities costs, and who the neighbors are, can anyone tell me the important questions to ask about the building?
Thank you
