Need help evaluation of "cash on cash ROI" for the property

[Ivan Wudexi]

Hello,

I am a beginner investor trying to purchase my first property. I am planning to do a house hack on a property. I used the calculator and got a 41% CoC ROI for that property. I feel this is too good to be true. I wonder if anyone (neutral) would be willing to help me cross-check my numbers.

I am happy to connect to provide details. 

Thank you. 

Best regards,

Ivan
