content: this is truly the most compelling book on commercial office space that i have read, and i have read all of them. It is short,concsice and to the point.Tunis captures the essence of what it means to negotiate for a piece of space and delivers it in a way that the layman can understand even the more complex points. A one of a kind book that i would heartily recommend for anybody looking to get in the commercial real estate field or just searching for office space.
