first investment, wholesaling

[Marissa Perez]

I recently went to an investor group in Dallas tx. From what I learned there was to find a motivated seller get the house under contract for 70% find a buyer and sell it to them for 80%. It was pretty vague so I’m still having trouble figuring out everything because if the house needs repairs do I have to deduct that from the 70% and after how much does the seller get and how much do I sell the property for?
