How do I mark up a deal for profit

[AL Wimberly]

Hello my is AL Wimberly, I am somewhat new to this flipping houses concept, but I had educate myself to the point I do understand most of the concept. So my question to you is I am working on possibly getting my very deal under contract on flipping home for a deal. EX - There is seller that is selling his home a 2BD home  $375,000 and most of the home in that area from all my research are going for $390,000.
