40 apt building Cap Rate

[Dave Halevi]

Hi all.
I'm putting all the numbers for that deal on the chart, and I have a few question.

That's a full rehab property.
1. Is there any rule of thumb that I can use when estimating the expenses of this kind of renovation?

2. Does the added table make sense to you?

3. After putting

all the info here, how do I calculate the selling price (for a full occupied, steady building)

Thank you guys. I appreciate your support!
