The warchest / opportunity fund I keep using the infinite banking concept which there are plenty of threads on.

This is INFINITELY the best information you can get.

Tax free growth is pretty hard to beat so if you don't need the money it sounds like a great long term wealth plan to me.I am intrigued by the "infinite bank" plan sold by these high cash value insurance policy people but have not done enough research to pull the trigger.

The house was less than a mile from a a big box supplier, which we thought would be convenient, but what I discovered is that the big box stores don't necessarily keep the volume of what you need on the shelf and the lead times for even simple things like lights and sinks can range from a few days to a few weeks.  

Put them in a fancy box and on a shelf at Walmart and see how many get sold.

I would HIGHLY recommend you do these two things this month:1/ Read Rich Dad Poor Dad2/ Starting listening to the BP PodcastThese two things will help you infinitely in trying to understand the possibilities and different ways to invest.  

I have no money down in the deal, so the ROI equation would say i have infinite returns (the bigger pockets calculator confirmed this as well). 

Infinite.

I only see upside--the potential to earn infinite return on a $0 investment. 

@Mark Gallagher you will find to be top shelf.. very investor savvy and very experienced..
