Does co-signing a mortgage hurt my credit?

Co-signing adds the debt to your credit report, which can affect your credit utilization and debt load. More importantly, any late payments by the primary borrower will appear on your credit report and can significantly damage your score.

Can I be removed as a co-signer on a mortgage?

In most cases, the only way to remove a co-signer from a mortgage is for the primary borrower to refinance the loan into their name alone or pay it off in full. Most mortgages do not have a built-in co-signer release provision.

Does a co-signed loan affect my ability to get my own mortgage?

Yes. The full monthly payment on the co-signed loan is counted as part of your debt-to-income ratio. Under conventional guidelines, this payment can be excluded if the primary borrower has made 12 consecutive on-time payments and you can document that the payments came from their funds.

What happens if the borrower misses a payment on a co-signed loan?

The late payment will be reported on both the borrower's and co-signer's credit reports. You typically will not receive advance notice, so it's worth setting up alerts or asking the lender if you can be notified directly.

What's the difference between a co-signer and a co-borrower?

A co-borrower is on both the loan and the title to the property, sharing in the ownership. A co-signer is on the loan but not typically on the title — they're taking on the financial responsibility without the ownership interest. Both are equally liable to the lender for repayment.
