I completely agree with @Ashish Acharya's points about the cost-effectiveness of a HELOC and the potential credit implications if it’s secured by your primary residence.

Owner financing and HELOC on personal residence How did you add value to the deal?

no reports of incidents with our residents but there were some people injured and some homes damaged. 

You could do something like what you want if it was your personal primary residence and even then the interest rate would be ugly. 

Investment Info:Single-family residence fix & flip investment.

It's important you understand this, be prepared, and expect that going in.

Is that amount worth risking at this time potentially having to pay from your primary residence?

What was killing me was that I thought I was being told that preparing for vacancy/management/maintenance/repairs/etc. was so much less important than appreciation, that I shouldn't concern myself with cashflow at all and just pay whatever price with total disregard for carrying a mortgage for 30 years and concern myself with only the mortgage PITI.

However if you liquidate the Bitcoin, and can show evidence that you were the one who made the initial investment(s) via bank statements, then those funds should be able to be used, as long as you are prepared to show all that. 

Property owners' and managers' sole recourse for encouraging residents to pay is unavailable.
