From a cash on cash return basis, it is pretty much mathematically equivalent to traditional financing.

Why do we make students take advanced mathematics past basic arithmetic?  

The 30k was just "invested" at a fixed rate return of whatever the mortgage rate it paid off was at.Now how everything ties in with the move and getting situated at the new job and all that, that takes it away from a pure mathematical/leverage situation, and is also very personal.

Once an investor can push past the unfounded fear that there is an overarching market force equation that counteracts all the mathematics of profit, he or she can begin to focus on the individual opportunities that present themselves every day.So, the next time someone asks you, "How's the market?"

Mathematically, it makes sense.

The billing should be logical with a mathematical formula. 

@Andrew Davis @Jay Hinrichs You guys are a lot smarter than I am when it comes to the mathematics of these investments for sure.

I have a bachelor's in Applied Mathematics and am employed as a junior software engineer.

This would equate to $1,550 per month over the course of 50 months which fits into the 2% rule...I ask this because, in my opinion, this is a pretty good deal for me and I would like to use a simple mathematical metric for evaluating purchases like this in the future.Does anyone have an idea on how I could evaluate this correctly?
