You arrive at the same result mathematically, however you arrive at it using an incorrect method.

It makes no mathematical sense to pay down anything except to get rid of PMI.

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?"

The mathematical formula is 5:1.

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?

Mathematically, it makes sense.

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

To bring it back to mathematics, you have this dilemma whether the market is up or down.  

Obviously, single family homes are not commercial property, but if you can find a way to mathematically quantify your question, you will be happier in the long run. 

The billing should be logical with a mathematical formula.
