Do I need a co-signer for an apartment?

A co-signer may help some renters strengthen an apartment application, but it depends on the property manager's screening rules and the full application picture.

When a co-signer may come up

A property manager may mention a co-signer if your income is below their example threshold, your credit file is thin, your rental history is limited, or your employment situation is new or variable.

What a co-signer may need to show

The co-signer may need to complete a separate application and provide income, credit, identification, and contact details. Some properties also use higher income expectations for co-signers because they are backing the lease.

What to ask before applying

Ask whether the property accepts co-signers, what documents are required, whether the co-signer needs to live in the United States, and whether fees apply before you spend money on an application.

Other ways to strengthen an application

If a co-signer is not available, a larger move-in buffer, clearer income documentation, a roommate, or a less expensive apartment may improve the overall affordability picture.
