Debt Fraction with Partnership Flip Financing

For a utility PV project with leveraged partnership flip financing, how do you determine input of 35% bank loan and 40% tax investment?

For the leveraged partnership flip option, SAM calculates the debt fraction (I assume you mean a 35% debt fraction) as a result, so you can't specify it as an input. If you want to achieve a specific debt fraction, you'll have to experiment with different input assumptions until you get the desired debt fraction.

On the Financing page, the Tax Investor Share of Equity Contribution variable is where you would enter the 40% tax investment.
