$500 rents just don't work mathematically.

BS in computer science and MS in financial mathematics - the study of math equations behind exotic instruments such as options, futures, CDO's, CDO^2 (yeah that thing that blew up the housing market back in 2008). 

The BRRRR method made the most sense mathematically to us, and I consumed as much informational content as I could.THE JOURNEY:Step 1: We bought our first home (primary residence).

I did so because I am here to build wealth and single family didn’t do that for me mathematically.  

I am confident of my cost estimates because 1) I have taken the time to mathematically calculate expected cap ex 2) I have been doing this for quite a few years. 

This happening was a mathematical certainty to come, no genius on my forecasting it, it's just math's.CRE has a LOT of "pull" to get assorted bail-out's.

No one knows the magnitude of the demand shift and the supply shift, so we cannot "mathematically" say we know what is going to happen.

You're not buying a mathematical share of a corporation or a virtual slice or a business.

Your advice is so narrow minded to full time or homebased investors I can't believe that I am the only one that ever sees this when they read your posts.I will never personally throw away a 15% COC return because it doesn't meet some ridiculous forced appreciation projection, or whatever other mathematically self-stroking overly analytical criticism can be thrown at it.  

Machine learning is basically, a mathematical/computer algorithm that can automatically improve itself using experience in the form of previously collected data.
