Please refer to this Spreadsheet:To do a basic IRR calculation, you will need to project out a bunch of things including:1) Your Investment: Cells A1 to B72) The Mortgage Balance Reduction: Cells A9 to B143) The Future Value you will sell the Investment: Cells D1 to E124) The Proceeds after the Sale: Cells D14 to E215) Your Rents and Expenses and how they will increase throughout the 10 Years: Cells H1 to L26) A Chart which will take into account all the above for the next 10 years: Cells G6 to M18.After totalling up everything, you will get a single number.
