So far, you haven't really proved (here) your ability to find REAL "deals"! 

Probably you will need to study the prices on that area.

However, there is not a reserve study.

Without an eviction proceeding and the Sheriff on site to forcibly remove tenants and their property, you are stuck writing letters,asking them nicely, waiting, praying, hiring someone to help.Used to work for a company that had issues with squatters and in particular, a certain tenant who intentionally screwed the company by forcing us to file an eviction, and then proving we (or rather the attorneys) processed it wrong, and then causing us to start over...

Not sure how you will prove to court one weekend of work took you a month to finish?

Then study up for a while.

How would I be able to buy a property initially and cash out refinance using the BRRRR strategy if I cannot prove income at the moment?

Specifically, what resources (such as a calculator) and or numbers do I need to study so I can filter through Notes and find ones that I know are good deals based on the numbers.  

Usually, the most important thing is to prove to them you're a trustworthy and strong borrower so they don't have to worry about default.

@ jay hinrichs - you don't know that the collapse in Vegas and Phx was caused solely because construction worker leaving... that is simply not true...Having a tons of OOS investors was another contributors.... there are many many studies/articles supporting that...When resession hits next, those OOS that can't find a tenant will bail... that was what caused the collapse of Phex and Vegas, at least partially....
