Frustrating wholesale deal!! need help

[Mikey Cas]

Hi everyone, I am working on a wholesale deal in my area in NY. It is in a great location and has tons of potential, I did the comps and everything. I want to go take a look at the property but the seller will not allow me unless I have proof of funds?? He is being very difficult and says he has dealt with a lot of people coming to see it that end up not closing. I tried explaining to him what I do(wholesaling), and that I have a list of buyers and investors with cash that can close immediately, and he just responded by saying "show me proof of funds". I want this to work and I dont want to annoy this guy where he ends up not answering my calls lol. What should I do? I don't think he has any patience from phone convos and I dont think he grasps the concept of wholesaling so this is a tough one. Thanks guys.
