Help with the numbers for a subject-to deal

[Ashton McCants]

Hey guys. I was hoping that you guys could help me out with the numbers for this first deal I am working on. This home was built in 2006. The seller is motivated to get this deal done due to moving to another state very soon. Currently the ARV is worth $129,329. The home was purchased for $75,000 in 2014. The current monthly expenses are as follows: Principal ($119.01), Interest ($258.47), Tax - city/county ($154.60), Insurance ($115), Mortgage Insurance ($78.56) and Overage/Shortage ($19.68) for a total monthly operating expense of $745.32. The current rental rate for the area is $1150 (Zillow). I am currently using 2 separate calculator to calculate my monthly cashflow. One of the calculators has me cash-flowing at around $225 per month while the other calculator has me cash-flowing at just over $20 per month. Any help with the calculations would be greatly appreciated. Thank you in advance.
