When the ROE is significantly smaller than my CoC return (based on initial investment) I know it's time to make a move to increase the velocity of the money.

If you plan on being a very active investor, it's possible but you will need to keep the velocity of your money up high.

One of the issues in the “calculations” of the “velocity” believers is that they do no accounting for the time value of money.

The key is velocity—keep your money moving and growing.

Price inflation is more a function of velocity than supply of money, and they've found that more printing does not equal more velocity.

This suggests solid demand, but there’s still room for price adjustments—key for investors looking to acquire properties below market value or add value through renovations.Market Velocity & Turnaround TimeHomes are selling in a median of 46 days, meaning well-positioned deals can move quickly.

Is is the extra principal payments, not velocity banking that matters.Of course the guru just happen to be selling these velocity banking services... 

we have to have pre sales my bank will only give me a certain amount of spec loans but unlimited amount of pre sales. its the only way to keep velocity when you have a larger project like us ( 90 homes) We have been blessed no questions about it.. we made some critical decisions when we started that now look like genius moves :)

Notes are all about velocity of money - faster the money comes in the more valuable the note.
