Wholesaler Being asked for POF

[Mason Jobst]

Hey so I am new to the wholesale business from Indiana. I have had a couple contracts set up and ready to go with sellers but they keep asking me for POF last sec what should I say/do to let the know I'm a wholesaler and I will be flipping the house to make a profit without scaring them off? I'm 20 years old and don't have the money to purchase a home obviously! Please help !
