You may require a co-signer if you have:
- Limited or no significant credit history.
- Income that doesn't meet the rental property's requirements.
- Limited rental history.
A co-signer can help you qualify for a rental property that you might not be eligible for on your own in these situations. However, it's important to note that a co-signer cannot substitute for a low credit score. If your credit score falls below the required threshold, your application may still be declined, whether or not you have a co-signer.
