I've secured financing, decided that pursuing a BRRRR deal sits well with our risk tolerance and financial situation, and now we have to find it.While "driving for dollars", Zillow, and networking have landed me a couple leads, I feel as though working with wholesalers will be a huge asset. 

Try Triad Financial, Vanderbilt or 21st Mortgage.

My biggest question is should I roll my old 401(k) into an individual IRA or should I wrap the two together and then borrow from them the way you're suggesting above.The idea of borrowing from my 401(k), and then paying it back over five years is really appealing.

When you say US compliance costs are you referring to the individual's income taxes?

I look forward to making some mutually beneficial contacts and building long term relationships with like minded people seeking financial freedom, abundance and release from the "rat race".

To ensure if I am gone that my family is well taken care of financially.

As suggested, focus on what the rest of the credit report tells you regarding history of collections, accounts 60 and 90 days overdue and just how much of this applicants funds are tied up in financial obligations (car loans, student loans, etc.)

In that case I would not mention offer price without seeing their financials first. 

My ultimate goal is to develop a passive income and become financially independent so I have more time doing important things like...saving the world and searching for long lost treasures and civilizations.  

As much as I love coding, I truly believe the road to financial freedom is investing.
