8. Consider the graph below - representing the effect monthly rent and expected treasury rate on the IRR of an investment in an income producing property. IRR: / PV(NOI+REV-DS) Monthly rent/unit 11.724% 20.666% Input High Input Low Ex. treasuries rate 13.816% 18.929% Baseline - 16.4385% 1170 12% 13% 14% 15% 0491 17% OLOT 19% 20% 21% Which input has a greater effect on the IRR of the investment. 1. Monthly rent - because it can yield a higher overall IRR 2. Monthly rent - because it yields a larger range of IRR 3. Expected treasury rate - because it yields a smaller range of IRR 4. Expected treasury rate - because it negatively affects IRR while monthly rent positively affects IRR. 5. No way to determine without knowing what the monthly rent or treasury rate will be
