100% VA disability as only income

[Andrew Sparks]

I would like to do some fix and flips and some buy and hold investing. 

Problem is, my credit isn't the best and I don't have a W-2 job. I do a few things here and there for extra income on top of my disability pay (door dash, stock trading)

Being 100% total and permanent I would think is favorable to banks because its guaranteed income for life. 

Was wondering if anyone has experience with fair to good credit, and VA disability as their main source of income (at least "verifiable" income) and could give me some advice...

I have an opportunity to wipe out most (if not all) of my debt, but then I wouldn't have any cash on hand.

Would it be best to pay off MOST of my debt and keep a chunk of 15-20k aside and use that as a down payment on a fix and flip or a buy and hold?
