Honest bit

What these nine tools won’t do

They won’t replace a quantity surveyor on the deal you actually pursue, they won’t draft your JV waterfall, and they won’t tell you whether the vendor is bluffing. What they will do is screen ten deals in the time it used to take to model one — so the QS fee and the legal time get spent on the deal that’s worth them.
