Whether you can get a business loan with a poor personal or business credit history depends on the lender. Some may require you to provide assets to act as security, while others may need a guarantor who can cover loan repayments if your business is unable to.
If you have a low personal or business credit score, you may find you can improve your chance of getting a business loan if you look to borrow a smaller amount. Alternatively, there are some business loans specifically designed for people or businesses with poor credit history, known as bad credit business loans. However, keep in mind both of these options typically charge a higher interest rate.
