Do I need a bank guarantee to get a mortgage?

Verified 16 October 2026 - Public Service / (Prime Minister)

To grant you a mortgage, the bank may require you to have a deposit. The bank guarantee is a financial institution that undertakes to repay your mortgage if you do not do so. Usually, it is a partner of the bank. We present you the information to know.

FYI

The deposit can also be a natural person, but this type of guarantee is not always accepted by the bank.

Generally, the bank puts you in contact with a financial organization specialized in surety and of which it is a partner.

The bank sends your request to the bank deposit.

The bank guarantee examines your request taking into account your professional situation, your debt ratio if the bank grants you the requested credit, and the amount of your personal contribution.

The bank guarantee forwards its response to the bank, which communicates it to you.

FYI

You can suggest that the bank contact another financial institution. If you are a civil servant, you can call on your civil servant health insurance.

FYI

The bank guarantee is one of the bank guarantees for a mortgage. It also exists the conventional mortgage and the special legal mortgage of the lender of money).

Each bank guarantee sets its subscription fees.

Taking out a bank guarantee is cheaper than agreeing to a conventional mortgage or a special legal mortgage from a money lender.

But you can recover a portion of the subscription fee at the maturity of the loan (i.e. at the end of the repayment of the credit), under certain conditions.

Unlike a mortgage, you don't have release fee payable when you sell your property during the loan.

If you are unable to repay your monthly payments, the bank guarantee shall reimburse the bank for the outstanding capital.

The bank guarantee then contacts you to agree together on an amicable solution to allow you to repay your credit (for example, reschedule your monthly payments).

However, if you are unable to repay your loan, the bank guarantee will incur a seizure procedure that can go as far as the sale of the property for which the bank has granted you the credit.

Please note

The bank guarantee should not be confused with borrower insurance a mortgage. Borrower's insurance only intervenes in case of non-repayment of the mortgage due to death, disability, incapacity, or possibly loss of employment.
