General question on utilizing a strategy

[Grayson Grzybowski]

If I find a property that I want a hard lender to help me with and they fund 90% of the cost plus 100% of the rehab, does that mean when I flip it I have to pay back the rehab costs as well? Sorry that this is a stupid question. I am trying to learn a different path in generating to making money in this market. 

If anyone could point out a good book from here that would be help too
