I can see setting up the escrow account but I don’t see why they would start the title work until they knew they were writing a title policyThey'd have to set up the title escrow account if only to receive the deposit. They would have received the funds before ROFR and would have to process the transfer of the deposit back to the original buyer once Disney took the contract.
Collecting and placing third-party funds into an escrow account is a highly regulated process. I'm guessing there is a very formal process that must be followed and that the file must be fully set up before they can accept even $1.00 in funds.
