How To Prepare For a Flip When Seller Being Difficult?

[Aldo Chandra]

Hello BP Community, 

Currently I am under-contract through a wholesaler. The house is currently occupied by the homeowner and I need to get my contractor inside the home to inspect and create floorplans. The Seller is being difficult as I am being told by the wholesaler. I do not think they are trying hard enough to get my guys 30-min to 1-hour. 

What are my other options? Should I go ahead and ask the Seller themselves?
