So someone can just stop paying taxes and create a funding gap for our public schools, firefighters, and county road maintenance and now private investors & Counties are going to bankroll the cost and administrative overhead to sell their property at auction and give them back the net auction proceeds?

I would think you would need a pretty large bankroll to start with this as presumably you would take over any mortgage payments and maintenance and have no income coming in from it. 

That would have been 9k of cash that I wouldn't have had to move into my next BRRRR, (that times my 18 loans would've brought my active bankroll down GREATLY).  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------  As implied by this Post I am worried that my current loan structure is subpar to what I should be shooting for.  

Do you have any recommendations on how to continue to work the next deals in this situation, or do I just have to build the fire slowly and let the cash flow and equity increase to bankroll deals next year and the year after?

Why not take a Heloc of like 100k and use that as your bankroll and then use Hard Money to fund 80% - 85% of the deals. 

You have 100k and can afford it but you might get in over 50k for a deal, that's half your bankroll. 

Lending in CA is not great unless you have a massive bankroll. 

Essentially, his partner (you, in that scenario) are providing the bank roll and you get interest and owner ship. 

Who's going to bankroll us and stream it?

I'm not familiar with purchasing partials, but it seems like a good option while in the process of expanding your bankroll.
