Earnest Money as a Wholesaler

Hi! I’m wondering how you experienced wholesalers structure your inspection period and earnest money deposit in your contracts. 

Do you put a small amount (for example $100) in escrow when you and the seller sign the purchase and sale agreement and then after the inspection (and when you’ve found an end buyer) you have the end buyer put a larger emd in escrow? At the end do you get your initial $100 returned at closing? 

How long of an inspection period do you shoot for?
