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.)  

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.

@Scott Carson  Geometric progressions ARE fun!!!  

The stimulus has been growing geometrically, it has now gotten to truly huge proportions.

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. 

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.  

And that is what accelerates your investing geometrically.

Is the compounding calculated with an arithmetic or geometric calculation?  

@Steve Short Love the theory of exponential and geometric expansion. 

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.
