A co-signer is someone who agrees to share responsibility for your loan if you can't pay. Lenders often ask for one if your credit is new, limited, or lower, or if your income alone doesn't meet their guidelines.

**How It Helps**
A co-signer with stronger credit or higher income reassures the lender, which can mean faster approval and sometimes a better interest rate for you. The co-signer doesn't need to make payments-unless you stop-but they do become legally responsible.

**What's Involved**
Your co-signer will be asked to sign loan documents and may need to provide income verification. Both of you will see the loan appear on your credit reports.

Our finance team at Castle Chevrolet McHenry can walk you through whether a co-signer makes sense for your situation and what the lender will need. Give us a call at (779) 600-2956 to discuss your options.
