@Scott Carson  Geometric progressions ARE fun!!!  

So, we're looking at geometric progression, or a doubling every few months (assuming 2 months for closing, rehab, leasing and getting our HELOCs in place.)  

Even then, you're still dealing with statistical probabilities - meaning there's a chance your results will be better or worse than the models.If you're married, building a joint risk profile can be geometrically more difficult. 

AssetBuilder actually has a nice chart showing how reliable their returns are based on their targets here:Growth Of Wealth By ProductThe geometric mean for our overall portfolio for the last 4 years has been: +25.7%+20.7%+20.1%+19.7%It is getting harder and harder to make it grow at this rate with more under management so I expect it to decrease modestly for the next several years unless our spec projects exceed expectations.In general we try to minimize risk on projects held for longer durations.

And they're right just like the 1% who tell you to sell are also right.The 1031 represents a powerful tool to geometrically grow your personal portfolio using deferred tax dollars to accomplish that growth.  99% of the investors on this site are in growth mode.  

As an intermediary for 1031 exchanges Geometric increases in exchange activity for us year over year.  

Is the compounding calculated with an arithmetic or geometric calculation?
