The reason I asked about a short sale book, is because out side of "gurus", I haven't found one available on a book shelf.

I am essentially getting back twice the cash I originally put in so in essence I will have a negative or zero "initial investment" amount and will have "infinite" returns.

Every hardware store has the caps, they're cheap, and nearly infinitely reusable... just toss them back in your "plumbing" toolbox when you're done.A couple of tips on replacing shutoff valves: if the existing valve inlet has a compression fitting on copper pipe, 95% of the time you can re-use the old hex nut and compression ring/ferrule/"olive". 

For example, I’ve recently locked up a property that will be a BRRRR that will allow me to pull out all of my money giving me an infinite cash on cash ROI.

Why are some properties in this area flying off the shelf while others are sitting? 

if its bad the investors loans freeze and only those TOP shelf borrowers have access and it wont be just fico driven.in the last recession investors loans for virtually anyone froze NO one could get them.. now I am not predicting this but it did happen. when things get tough investors loans are the first to go.. and not be offered no matter LTV or fico. 

No matter where you live or where you own assets, I personally recommend the Series LLC to be a great tool for the individual investor who is planning to expand their operation, as it allows for you to scale infinitely for FREE- check out this article to learn more.Running without an LLC works perfectly until it doesn't - but when a lawsuit is filed you can't change your ownership structure.

Those assets are really just recycled product that has a very short shelf life for investors.

With this scenario, your return is infinite.

In the end, you will have ZERO out of pocket and a true infinite ROI!
