What a Co-Signer Is
A co-signer is typically on both the mortgage and the title of the property, sharing full responsibility for the debt and having an ownership stake in the home. This is the more common arrangement when a co-signer is helping a family member qualify for a larger mortgage amount.
What a Guarantor Is
A guarantor is on the mortgage but usually not on the title, meaning they guarantee the debt will be paid without holding any ownership interest in the property. This arrangement is sometimes used when someone wants to help a family member qualify without becoming a co-owner of the home.
Why Lenders Distinguish Between the Two
Lenders view guarantors as a backstop who strengthens the application through added income and credit history, while co-signers are treated as equally responsible parties from the outset. Both are legally on the hook for the debt if payments are missed, the key difference is largely around ownership.
- Guarantors typically are not on title
- Co-signers usually share ownership
- Both share responsibility for the debt
Which Option Fits Your Situation
If the person helping you qualify does not want any ownership stake, a guarantor arrangement may fit better. If they want to share in the investment and potential appreciation of the home, being a co-signer with an ownership interest may make more sense for everyone.
Getting Everything in Writing
Regardless of which arrangement you choose, put the terms in writing, including expectations around payments, what happens if the primary borrower struggles, and any plan to eventually remove the guarantor or co-signer through refinancing.
Frequently asked questions
- Does a guarantor's credit get affected the same way as a co-signer's?
- Yes, both are legally responsible for the mortgage debt, so missed payments affect both parties' credit regardless of the ownership arrangement.
- Can a guarantor later be added to title if they change their mind?
- This would typically require a legal transfer of title and possibly a mortgage adjustment, so it is not automatic and should be discussed with a lawyer.
- Which arrangement do lenders prefer?
- Lenders generally accept either, the choice usually comes down to what the family members involved want regarding ownership rather than lender preference.
