CoC and 5 year annualized return

[Ezekiel Tolentino]

Hello, I'm using the bigger pocket calculator. I'm getting 2-3% CoC for a rental property (which I think is low) but in the 5 year annualized return it's around 14% (which sounds acceptable). What's the difference between this two numbers? How do I interpret this difference? Which number is more reliable in terms of return on my money?
