pA private mortgage holder asking for additional payment after closing, can they do this?

A private mortgage holder, after I made first mortgage payment, is asking me to pay almost another $1,000.00, 10% interest for the two months. His money was sitting in escrow before closing. It is a 10% mortgage with 10 points and the points are rolled in the mortgage. He said he does not want me to homestead my property. The purchase price was $115,000. His mortgage is about $62,0000 for ten years. Is this right to him request additional funds on top of everything else already recorded etc.? Lender lives in MA, I live in property in Florida. We’re not in foreclosure, just made first payment.
