an assignment contract is a strategy wholesalers use to make money without using their own money. first, you want to be transparent with the seller. the seller should know that you are an investor who will be wholesaling their house. you need to help them understand how the process works. second, make sure to raise the purchase price (to the buyer) and build your fee into that price. this markup is your wholesale fee, also known as an “assignment fee.” assignment fees range from $5,000 to $20,000 depending on the deal. that means you can build in a $15,000 assignment fee for yourself.
