band of investment investment, correct, capital, understand

svgleeson

Can someone provide me with the correct way to find the x to the below?

I understand that finding the cost of capital through the band of investment is effectively equal to a WACC for real estate investments. However, the cost of debt is typically calculated as yield + % yield for amortization.

How do I calculate the % yield for amortization portion on my hp12c given assumptions about the loan?

Thanks all

Eric
