I agree with Chris.
Here is how it goes for me
Me: Can you tell me about your property and why you need to sell
Seller: blah blah blah my house is great blah blah i need to sell fast for a random reason.
Me: What is your asking price
Seller: 55k
If this sounds like a good priced home that I can wholesale I continue the convo, if not I save their info and call them again when they become more motivated to sell.
Me: Is the home listed with a realtor
Seller : no its not (if yes then bye bye from me, save info and call if listing expires)
Me: ok great, when would be a good time for me to come view the home
After driving to the home & building rapport with the homeowners.
Me: Whats the lowest you would accept as a cash offer that can close in 2 weeks.... then I negotiate a price with the homeowner.
Seller: Well I only owe 50k on the mortgage so I would take 50k cash
Me: Ok that sounds great, i will not be purchasing the home myself but what I can do to help you out is put this property under contract so i have equitable interest in your home. I will then spend MY money to market your home and will also show it to my cash investors. I have a ton of friends who are buying properties right now to buy and hold as rentals, so I will mark up the price and sell it to them if thats ok with you.
Seller: Sounds great
If seller says "but what if i find my own buyer, I don't want to be stuck in a contract with you if I sell it on my own"
Me: Well thats not problem at all, we can just sign a simple one page addendum to the contract that states my contract is only valid if MY COMPANY finds the buyer, so if you sell it buy yourself I will happily rip my contract up.
Seller: Ok thank you so much for your help
Me: start blasting the property on CL, e-mails to my cash buyers, and go crazy with bandit signs.
This is for wholesale leads only, the conversations go much differently if the homeowner is behind on payments or something of that nature.
Hope this helps!
