Ernest Money Deposit

[Tomarcus Dowdell]

Hello Everyone, 

Question: How do you determine how much Ernest Money(If Any), should you leave for a Deposit?  I was close to getting a property under contract but the seller wanted me to deposit $500.00 dollars. He was selling the property for $10,000 dollars, i agreed to put down $100.00 but that was too low for him. So, how do you determine how much is fair? 

Thanks,
