Viability of this Whole Lease Option scenario

[Brian Huber]

Hi, I came across an ad for someone willing to lease option their house. They wanted a non-refundable option fee of $2K.

Could I work with them to find a Tenant/Buyer, ask the T/B for a $4K option fee in order to profit $2K from this deal?

Is this possible? What are the pitfalls/issues, etc.?

Thank you for your insight!
