Time Value of Money

[Dan McClain]

It's been a while since I have last posted. I have been mostly absorbing everything I can from the various threads on this forum. Thanks to everyone for the invaluable insights on various topics.

Simultaneously, I have been reading through "Real Estate by the Numbers." The premise of the time value of money struck me: "Money in hand today has earning potential, and we can turn money today into more money tomorrow by investing it."

I have been saving for a down payment on a rental property. With the idea of "we can turn money today into more money tomorrow by investing it," I place most of this within a taxable brokerage account where it grows based on the market broadly speaking. Does anyone do anything similar or have a better idea? 

Thanks in advance for your input.
