Geometric progression in action!  

He is horrible at math but does a fantastic job at the few geometric equations he uses over and over again.Also, keep in mind you wont be a room full of investors scrambling to do math equations and the first one to complete gets to make the offer. 

Also if you have a cap rate of 3% for a property that has an NOI of 10 million dollars per year and you are able to add 1 million dollars a year to that NOI your appreciation returns are non linear but rather more geometric. 

But yes for one property the solution that gets you maybe 85% of the way without the geometric progression in costs is probably an LLC owned by a trust.

This goes geometric after 3-4 years of building a portfolio while still working a day job to fund living.  

I'd also remove that geometric rug I see in some pictures.The shades are unlevel in several pictures.

If growth is desired, the investor has energy, doesn't mind debt and needs tax breaks then a 1031 into larger properties allows for geometric growth and new depreciable basis. 

Your ROR on that move depends, of course, on the time interval between these two, but simplistically, it's what's called the geometric mean of those two values.

The fact that you have 25 mortgages makes it geometrically more complicated.

But this type of investing becomes geometrically more risky as you near the end of your career.
