As a Senior parent or relative of a first-time home buyer there are times when you are asked to help.  In the last few years, we have seen a surge of first-time home buyers going to the “Bank of Mom and Dad” for assistance with a down payment.  And even if they have the income to pay a mortgage, they may have weak or poor credit and now need assistance securing a mortgage.  This article published by Ratefair helps to explain what is entailed if you co-sign or guarantee a mortgage for a child, family member or friend.  At we advise our clients that they should  consider speaking to a lawyer to ensure you are fully aware and comfortable taking on this duty.

Co-signer vs. Guarantor

With the cost of homes increasing in certain markets and the stress test in place, it’s becoming more and more common for the average individual to struggle when it comes to qualifying for a mortgage. Unable to obtain financing on their own, they often look to family members to step in and provide financial support. One way family members can help is by becoming a co-signer or guarantor.

Though they are often used interchangeably, there are very distinct differences between a co-signer and a guarantor in terms of rights and responsibilities; one should not be confused with the other.

The co-signer

A co-signer is typically brought in to aid an individual who has a low- or inconsistent-income stream or credit issues, and thus, is unable to qualify for a mortgage on their own. As a co-signer, their name appears on the title to the property; they co-own the home with the person living in it and making the mortgage payments.

Because the co-signor legally owns the property, he or she is required to sign all the mortgage documents and is liable for all mortgage payments. Though the co-signer is not likely the one that will be making regular payments, they will be held accountable to this duty should the primary applicant fail to do so. The co-signors assets can also be at risk should payments cease, and the mortgage goes into default. If the co-signor dies, his or her estate assumes liability for the mortgage payments.

The guarantor

A guarantor can also help a primary borrower obtain a mortgage. In this case, the primary borrower usually has a weak credit score rather than an unverified or unreliable income stream. The credit score may be preventing them from securing a mortgage on their own, which is where the guarantor (who generally needs to be in better financial standing than a co-signor) can step in and satisfy the lender’s criteria for approval.

Unlike a co-signor, the guarantor’s name does not appear on the title of the property, only the mortgage. They are not legally entitled to any ownership of the property. The job of the guarantor is to guarantee that the mortgage payments will be made if the primary borrower gets approved.

Because the guarantor does not legally own a portion of the property, they typically only become liable for the mortgage once the lender has failed to enforce collection payments from the primary borrower. Because of this risk, certain lenders disallow guarantors unless they are the primary borrower’s spouse.

Risks and exit plans

Both co-signors and guarantors assume some level of risk that can leave them on the hook for the mortgage. Co-signers are legal owners of the property and are liable for 100% of the mortgage, though they retain the advantage of potential property appreciation and may be entitled to a portion of the proceeds of the sale of the property. Guarantors only become liable for the mortgage once the lender has exhausted all options to collect payment from the primary borrower, but they won’t partake in any gains from the sale of the property as they have no ownership rights.

Once the primary borrower’s financial situation has improved, both parties can agree to have the co-signor or guarantor removed from the mortgage. It’s critical for each party to consider their personal needs when thinking about going on another person’s mortgage. This could affect credit and finances in the future, and it is important to understand all details before signing on the dotted line.
