I racked up debt, at times putting expenses like property taxes on a line of credit.

You said "100% of our funds were investors" then "my capital came from bank Lines of credit NO investors", so wondered exactly how much of the 100% was replaced. 

LoL, they were all wiped out of course.

Look up the courses taught by Justin Kivel, specifically the Pro forma modeling course and the real estate financial modeling boot camp.

But just hating on wholesaling in a wholesaling forum is so unbelievably pointless. its not dead per se  but it is starting to be regulated as it should.. oregon just passed their version. where to wholesale you now need a license and over site by the RE commission.. along with criminal back ground and a BOND.. and as we know not everyone can pass either of those with the bond being the tough one if you have bad credit your not getting a bond.

Of course have your costs researched first bc the buyer will want to know how much it will cost them to buy.

Par for the course based on our prior conversations.

You can work with a local credit union that does HELOCs, Home Equity Lines of Credit or Loans, on investment property.

Quote from @Raymond Kalonji: In your opinion, what would be a reasonable minimum credit score?

I own the property free and clear and i use the equity as part of my business line of credit.
