purely my fault. 

Is this purely a numbers situation where I may just need to increase the purchase price?

My purely hypothetical car wash mortgage client has 3 vending machines full of vastly overpriced car detailing stuff (next to a physical bulletin board showcasing some shiny freshly detailed sexy cars...), and one with snacks at normal vending machine markups (buys either at Costco, or whatever he finds on sale).GL.

At the end of the day, RE investing just isn't purely about numbers.
