[Calc Review] Confused if I did this properly

[Mathios Yonan]

I'm 17 years old, currently practicing, and I ran into this property and decided to analyze it. I think something about this is incorrect because the CoC ROI is insane. I've listed the 2 sources that I used to fill out the info. Brief Description: Duplex, 3 bed 1 bath each. Listed at 180k. More info about expenses etc is listed in the first link below the calculator report.

**Already Sold**
