WACC (Weighted Average Cost of Capital)

Hi,

I'm new to BiggerPockets so I'm not sure where I should be posting this question. 

Does anyone here use WACC? If so, how do you account for points upfront? 

What I'd like to do is use it to run Monte Carlo simulations on capital mixes and see where my optimal profit will occur. For example. does it make more sense to borrow 90% of my deal at a 12% rate but pay points upfront vs. pay an equity investor 14% to partner with me on a deal. When I turn all the percentages into variables I will run thousands of simulations to find my efficient frontier. Thanks!
