Using hard money. Seller wants POF. What do I do???

[Dallin Wood]

I have never had this happen before.  We are using hard money to purchase a home and the seller asked me to send them Proof of funds from the Hard Money Lender.  

Has anyone else ever had this happen before?  What do we do it looks like our offer is going to be accepted and we don't just want to walk away.

The contract is NOT conditional on appraisal nor financing and we want to close in 14 days.
