A very common structure is for you (the general partner or GP) to offer your investors (limited partners or LPs) a fixed annualized non compounding preferred return of say 8% of the investors invested capital.

This adds up as it is compounding.

Also remember that appreciation compounds.

We also had to do some carbon fiber strapping as our foundation was bowing inward as well.  

Most of the time, I don't shy away from homes with somewhat we basements or some settling, but I've seen homes with bowing walls that looked like they could one day collapse in to the basement.With that being said...

And the effects compound over time just like a stock portfolio.

Nobody wants to buy high and lose money, but by choosing not to take action I would intentionally forgo the most powerful potential feature of the compound interest formula, the exponent.  4.  

Sounds like a great tax shelter to save but you soon realize The fees they take are a compound growth killer imho

This is a compound interest formula...not a simple interest formula.

But you would only be able to save your income from your jobs to start investing again, whereas if you stay in your current situation, you could have the cashflow and your income to compound and buy more properties faster.
