At AI's new class in yield capitalization (General Appraiser Income Approach, Part 2), there was an example problem given in which the first three cash flows were negative, and the last two positive. The project yield rate was given at 11.5% (or something like that), and we were to solve for value. The instructor applied the 11.5% yield rate to all five cash flows and the reversion. I was OK with applying it to the reversion, because it sometimes works out that way.
But applying the project yield rate to the negative cash flows gave me a rash. The effect of doing that is to reduce the amount expended by 1/1.115^t, and I don't think that's right. The negative cash flows represent money expended to get the project going. It should (in an ideal world) be budgeted and fully funded. If that is true, IMO it should be drawing interest (and be discounted) at the safe rate, not the project yield rate. The instructor, a veteran of 20+ years' experience, said "No!" Being the perpetual iconoclast, I think he's wrong. What do you guys think?
