As an investor, you have an opportunity to make an investment in real estate costing $100,000 today. This investment would provide you with monthly cash income of $650 at the end of each month for 20 years (240 months). What is the internal rate of return (IRR)? (We take 20 years into account without selling the property, and the IRR is the annual rate of growth that your investment is expected to generate.)

Please provide both the IRR and RATE function results in an Excel file.
