I would put $6,000 in whichever account I end up choosing.On top of these accounts, I will save $1,000 per month in my savings.

Feel free to PM or post, whichever you prefer.

The difference would be that with Solo 401k you have the ability to take a personal loan from you account, which is limited to $50K or 50% of the balance, whichever is less. 

Simply means that a lender isn't going to give you a loan for more than 80% of the price or value of the property (whichever is less)Doesn't mean that you can't be creative with where the 20% comes from.

Keep in mind that when purchasing an REO, whichever purchase and sales agreement you use (state standard or attorney generated) it will be followed up with the bank addendum which will supercede the PSA.You should be familiar enough with PSA's, specifically, your state standard agreement, before jumping into these waters.

Would love to chat on whichever side interested to hearing what both sides mention, also provided an article that lead me to this great insight. 

So, I propose some questions to get the discussion started (whichever ones you're comfortable answering :-)).      1.

We advise $1,000 or 1% of purchase price whichever is higher.

which ever I pick I can still flip houses right?
