When looking for a guarantor, you should ask someone who you trust and feel comfortable talking to about your finances. Typically, this would be a family member or close friend.
They need to have a good credit history and be financially stable. Ideally, they would also be a homeowner.
However, becoming a guarantor is not something to be done lightly. If you are asked to become a guarantor, you should make sure you fully consider whether:
You can afford to repay the debt in full, even if your own personal finances change in the future.
The borrower is in a financial position to repay the loan they have requested over the specified period.
The borrower is responsible and can be trusted to make repayments on time.
The borrower definitely needs the loan.
You are willing to add a financial element to your relationship with the borrower.
