Can I make a verbal offer?
Legally yes, but realistically a seller will not take a verbal offer seriously. The seller will insist on a written offer with your signed signatures and maybe even an escrow deposit placed with a Title Company. The seller will also require a letter of pre-qualification from a reputable lender or a “proof of funds” if you are paying cash.
Providing documentation to assure the seller that you are creditworthy, serious, and committed will help during negotiations.
