getting access to property from out of town sellers or out of state etc.

Bird Dogs, Wholesaling
1 
   Hi I`m made serveral post before still trying to put the pieces together on wholesaling I`m still a newb, I had some questions.

  1. How do I gain access inside of the house from a seller who`s out of town or out of state? how do deal with this situation

  2. Do I have to negotiate that I need unlimited access to the property?

  3. How do I grant access to those i`m selling/wholesaling to investors or rehabbers? do I need to take care of this first between me and the seller?

Thanks
