So cash on cash is almost infinite.

In your scenario the CoC returns are infinite BUT I would be concerned about how little it is cashflowing and unknown expenses.

The only call out I possible have is that your partner is getting a 15% return on their cash and you are getting significant higher return for that, essentially an infinite return on money invested.

@Brian Simmons offers a good suggestion as well - a reverse exchange which while more costly than a straight exchange is infinitely cheaper than stroking that tax check.

When he went to refi to a conventional mortgage he actually got a few $$ back.That is true infinite return!

At the same time it said this power was not infinite could be limited by judicial review.So its settled constitutional law that the contract clause does NOT disallow actions by the state that violate private contracts.

Now, just because you can get to infinite return doesn't mean you should either. 

Its a bunch of elaborate marketing and a great web page for buying mutual whole life and using your policy value (cash value) to buy more real estate then using your real estate and paying back your whole life plan loan higher than the rate youre borrowing at so you can keep rinising and repeating.In theory you grow your wealth up more and more and build up your RE portfolio and you in essence "become your own banker," AKA nelson nash's book.Cash flow banking is a new marketing spin off for infinite banking (nelson nash), cash flow banking (website above),  private reserves strategy (anderson advisors in NV/WA),  bank of yourself (kim butler), and etc.The problem is funding your WHL (whole life policy) and every dollar you start out with hits huge drag because every dollar contributed only nets around 65-80 cents.
