Meaning you mathematically adjust for the higher overhead costs; if you have a bigger rent payment due at the beginning of the month, then you need to be making more cash flow to accommodate the additional risk.

It's mathematics.3.

Mathematically it wouldn't make sense to put more money towards a low-interest mortgage.

The mathematics can be simple here - mortgage minus adjoining unit(s) projected income.

You trying to convince me why this is the best choice (you can not POSSIBLY convince me because this choice is MATHEMATICALLY and universally wrong), is not going to magically make it work for you.So whether I am right or wrong is irrelevant right?

It really is a mathematical equation.

Let me tell you all something and I HOPE you take this to heart.As someone that clearly understands lead gen, and motivated sellers, and SEO and marketing, and rockets, and robots, and mathematics, and crablegs, and food in general...I can tell you flat out DO NOT HIRE any of these lead generating companies.

In response to the OP:Maybe in some mathematic scenario in which all the stars aligned perfectly... maybe you'd make a million "wholesaling".  

What are redundant mathematical calculations you carry out for each property you are considering?

Oftentimes one's primary residence is not an asset per the mathematical proof-point above.
