My Friend Wants To Use His Credit To Fund My Deals

[Jonah Wilson]

I don't know where to start as far as securing the funds on the next deal.

 Do we have to use a bank? 

 I'm more interested in using private lenders or is it a difference? 

My hardest step was getting a credit score above 700 and now we have a 750 credit score. 

After finding the right deal which direction do I go?

All advice wanted( good/bad)
