So yes they are mathematically the same, one’s just simpler to understand in a instance

What I enjoy about RE is that it is mathematically simple.

Everyone agrees (because it is mathematically correct) that to retire young the most important first step is a high savings rate. 

Right Amit, this problem is actually a simple mathematic equition:one wants to swap a lesser performing rental with the more performing investment.The problem is since the performance is set by market, thus the problem is becoming:one wants to swap a less performing single/MF rental property in specific regional to a regional syndication economy that's more performing.In reality, these are difficult as the home price is rising and rent growth for SFR is higher than the growth of apartment/multifamily complexes esp. if it's class A property.Solution ?

Not saying it’s not possible but it’s easy to rationalize stuff and do mathematics gymnastics to trick yourself into a lousy deal .

What are mathematical indicators people look at and where can one find ACTUAL and CORRECT data to support this?  

@Chase GochnauerYes when it comes to mathematics, your right, the more leveraged you are, the greater chance you have of achieving more wealth.  

Furthermore, Bill Gates spent 2 years in Harvard taking advanced-level computer science and mathematics courses.

I love to have my thinking challenged.I mathematically proved that it would be best for me financially to sell my home and rent, but I have not done that.

It depends on the person and what return they can get on there money you can mathematically determine which route is best by doing a discounted cash flow analysis to compare the three strategies.
