How much money needed to wholesale deal?

[Jeff Fairchild]

Ok, I need to know how much money I will need to shell out before I get paid :P

I've been told to say "I generally put $10 down to make the contract legal" or what have you, which is $10. Is this right by the way, or what is the least that people are getting away with as earnest money without RE agent? Any tricks for them not balking at the low amount?

Then, do I have to pay for the inspection up front?

Do I have to pay anything to get escrow started?

What other costs are involved?
