New to Wholesale

[Clay Turner]

Hello everyone. I'm new here. I have sold 4 properties through buying, holding until a buyer was found, then selling.  It worked pretty well but I wanted to try wholesaling.  I currently have a property under contract to buy/assign and am trying to find a buyer. It's vacant land. I'm selling for less than half of tax assessment in a pretty nice area. If sold at my asking price I'll make around $5k profit. My question is how do I handle the number one question.....Does it perk? As a wholesaler, am I supposed to perk test it myself (I was trying to pay little to nothing out of pocket on these deals), or do I include a clause in my contract with the seller that allows the buyer to conduct soil test and the deal is contingent upon results. Any help is greatly appreciated. Thanks!!
