Beginner, looking for feedback on rental calculator analysis

[Dan Palumbo]

Long time lurker here. I recently became a pro member and have been using the rental property calculator to examine listed properties to familiarize myself with the calculator itself. I am hoping I can get some feedback on my analysis of a property to make sure 1. am using the calculator correctly and 2. If I am assessing the results correctly. The linked property below seems like it might be worth following up on but am hoping more experienced members can chime in. 

Thank you in advance.
