Negotiating with a contractor

[Dante Foreman]

I have my first deal funded. Im 45 all in 35k will be used for rehab. Lender has me set up on Draw and inspection then payment for contractor after certain task is done. Although this isn't uncommon Im wondering how I can explain this situation with my contractor without offending them,or should I just raise funds for rehab or find partner and split profits for bringing cash to the deal.
