how to show occupied rental to buyers

[Brian Cooke]

When you have a house under contract that is an occupied rental you want to wholesale to landlords, how do you deal with showing them the property? I imagine tenants don't like people walking through all the time, and I don't like telling the owner I'm trying to sell his property before he has even sold it to me so can he please let me in again and again? (I would eventually tell the seller that I have sold my contract for such and such reason, not to worry they still will get the same deal and yada yada)
