Are you being offered a refund of equity of up to $2,500 to $3,000 in realtor rebate on a $225 purchase?
If not, Google seach this: FLORIDA REALTOR REBATE and ask for it to help you get a 2.625% rate.
A Verbal Contract is no contract at all; it is not binding. Only when put on paper is it binding.
Up to that time, and it is signed; either party can change their mind. Including you.
Good luck and may God bless
