What was my rate of return on this deal?

[Kenneth LaVoie]

Good Morning

I am pretty familiar with CAGR and IRR though no expert. I'm about to sell a 7 unit building I've owned for 13 years and I want to know what my "annual rate of return" was on the money invested. I'm thinking IRR is the best because the "cash flow" will be like the "dividends or interest" ... the "all in" at the beginning will be the initial deposit. And if I put any owner contributions that will go in as "deposits", then of course the final cash out at the end. Does anyone have some feedback on a good spreadsheet for this?

Thank you very much.
