I handled the sale of a vacant lot by putting my name on a sign and calling builders. I live in Georgia and flew to Tampa to pkace sign, locate buyer etc. i was able to negotiate a solid offer with a builder in the area. The seller (my personal friend and work associate) asked me to handle it for a $5000 fee as i spent 20 years in mortgage banking. Once we had a solid signed and counter signed Purchase Agreement I ensured the closing would be transacted without the need of a POA and that overnight curriers would provide docs for signature. They would be held in escrow until the disbursement date 2/4/19. The seller already paid ne $500 for expenses and which i believe shows intent to compensate me if I sell the property. Now he decided he just doesnt want to pay the balance . What are my options?
