Buying from Wholesaler- Sellers Disclosure?

Getting ready to buy a very distressed property through a wholesaler. I have family in construction who have looked at it and feel it has fairly solid bones and I like the location and think it's on the way up. This is not my first huge rehab so I am ok with that and the price. But is there no requirement for a seller's disclosure in this case? He has a contract with the seller which will then be assigned to me for a fee. There is no other paperwork. Obviously I will have a title search and get title insurance but I assumed they would still be required to fill out a SD but maybe not. Obviously the place is totally derelict so not much to disclose (basically check yes to everything being wrong lol) but I was just curious for the future. Thanks!
