It's never too early to start planning, and the sooner you begin, the more you can benefit from the power of compounding and tax-advantaged retirement accounts.

Does interest compound?

Just time in the market, compounding numbers, and cash on refi’s.

Don't underestimate the value of compounding $550k real today dollars, and don't overlook the discount factor for receiving future dollars. 

That is 155% return on investment (37% compounded annualized return). 

@Steve Guzek As I just read this I basically melted down and bowed to your feet.

Now compound the value of time by the value of mistakes and accidents, and the expenses of those, NOT made due to having gained knowledge from others?

I know how to use the compound interest calculator to see what happens at 7 percent for the stock market but I'm confused how the rental income works because he could just invest that additional 1k a month into the stock market too? 

When you take the funds out during retirement, not only is the original contribution tax-free (because you’ve already paid the tax when you first contributed), but the compounded earnings are also tax-free!

The inspection report noted some bowing in the foundation.
