How do you handle "good faith deposits" to hold a property

[Gloria Dulan-Wilson]

Have a single family property I'm looking to purchase - it already has a tenant and good cash flow; the realtor is not investor friendly and is demanding a $1000 good faith deposit, which I do not have - I'm working on getting a private lender. How do I handle this if the agent won't present the offer without a "good faith" or "earnest money" deposit?
