Answer:
IRR= 17%
Step-by-step explanation:
The internal rate of return is the profitability (IRR) of the money that remains invested during a project life. To calculated we need to use the net present value formula (NPV). The IRR is the rate at which the NPV is cero. I attached the formula but it is better to calculate the IRR using excel.
First, you have to copy all cash flows including the investment with a negative sign. Then you use the financial formula "IRR" in this way:
"=IRR(C3:C8)" (I attached the excel figure)
In this case, you have to sum the cash flow produced by the property plus the earnings of the its sale on year 5.
