In mixed-use development how do you allocate the infra cost / land cost / service charge?

As Mr.Zain requested that is my own experience on the issue of the question.

I always prefer the big picture method, as in I calculate all of the expenses be it infra, land or service costs for the whole project and then divide the whole combined cost on how much GFA I have to sell, if there is a leasing part of the project I divide by how much years I want my ROI be and ofcourse it have to be with the market price.The NSA I include in the land costs so it is already calculated in the expenses. 

My method seems a bit simple but in the terms of practicality it gets the job done and in an effective way.

Hi Rami Abbas,

How about sharing your own experience on this issue?

Infra cost and land cost can be allocated on the basis of gross floor area (GFA), net sellable area (NSA) or in proportion to the projected revenue.

Service Charges can also be allocated on similar basis.
