As well as being the first meeting with your new/future bank adviser, it's also a time to introduce yourself. the terms and conditions of the loan offer you will soon be signing : the terms of the contract, a reminder of the quid pro quos expected by the bank, early repayment indemnities, the possibility of modulating or postponing the maturity date, loan insurance, etc.
Unless there is a case of force majeure, your advisor will always accompany you. He or she is the guarantor of compliance with the conditions and quid pro quos agreed together.
The banking appointment is sometimes also an opportunity to discuss other banking services that the bank can provide.
