Please help me with wholesaling question!!!!!!

[Hung Nguyen]

Hi, please help me with my question about wholesaling.

Let say I have a house under contract. I find my cash buyer and he/she interested in it.

1.) Do the cash buyer want to came and check out the property? and how do I have access to the house?

2.) Do the owner give me the key or no? if not, do I call the owner/seller to meet me and the cash buyer at the house?

3.) When we all three there what if the cash buy try to back out the deal and work with the seller instead?

4.) Somehow What if the owner/seller knew i make $5k-10k off the contract by asking the cash buyer how much he/she offer me the contract for?

5.) What happen next if the cash buyer accept my deal? do I give them my original contract with the buy and they do the rest? or how is it going?

Please any one walk me through the whole step.

I am new to this please help with my question and concern I would be really appreciate. Thank You!!
