First House Hack - 90% Cash on Cash ROI

Hey BP! After grinding for a year, my wife and I FINALLY were able to purchase our first house hack. I think it's a pretty sweet deal for the first property we've ever purchased as an investment. My charts below basically just show the total savings per month we get from not paying our previous rent ($1710) - our new housing payment. The reason I have 2 charts is because there's a current lease on the other unit that is WAY below market rent ($1100-$1200). Once that's finished in April we'll begin renting out the other unit for what it's actually worth. I estimated 5% Repairs, 5% Capex, and 7% Vacancy. Let me know if you have any questions!
