When one person applies for a mortgage on their own, that person is the sole borrower on the loan. When multiple people apply for a mortgage together, they are co-borrowers on the loan.
While a co-borrower is typically a spouse, partner or relative, they can also be a friend or colleague. In most cases co-borrowers live in the property being financed together but this is not a requirement. In short, a co-borrower is anyone who is listed on the mortgage note other than the first borrower.
Applying for a mortgage with a co-borrower offers potential advantages and disadvantages, depending on the financial and credit profile of the applicant. Continue reading to learn how a co-borrower for a mortgage works so you can determine the best approach for your loan application.
What You Should Know About Mortgage Co-Borrowers
The Co-Borrower is Legally Responsible for the Mortgage
If you are listed as a borrower on the mortgage, you are legally obligated for the loan. This means that you are responsible for the monthly payments and ultimately repaying the mortgage.
This legal responsibility applies regardless of if you live in the property being financed or if you are only responsible for a portion of the monthly payment according to an agreement you have with the other borrower. Simply put, all borrowers are viewed equally from the lender’s perspective and held accountable for the mortgage.
Because you are responsible for the mortgage, the monthly payment is factored in if you apply for another loan. For example, if you apply for a car loan or another mortgage, the payment is included in your debt-to-income ratio, which can may it more challenging to qualify for the loan. Again, this guideline holds true even if you do not occupy the property or if you do not personally make the mortgage payment.
The Mortgage Affects the Co-Borrower's Credit Score
It is important to understand that if you are a co-borrower on a mortgage, the loan appears on your credit report and can impact your credit score. For example, if you miss a payment, become delinquent on the loan or experience another negative credit event such as a default or foreclosure, your credit score may be significantly negatively impacted. This is why it is important that you trust the other borrower on the mortgage and are confident that collectively you can afford the monthly payments.
The Co-Borrower’s Income and Debt Are Included in the Mortgage Application
The lender includes the monthly gross income and debt expenses for all co-borrowers in the debt-to-income ratio to determine the mortgage you can afford. If your co-borrower has significant monthly income relative to their debt payments, then the co-borrower should enable you to qualify for a higher mortgage amount. However, if the co-borrower has high debt expense relative to their income, then you may be able to afford a higher loan amount on your own as a sole applicant.

Additionally, if the co-borrower does not plan to live in the property being financed, then their housing expense such as their monthly rent or mortgage payment is also included in your combined debt-to-income ratio when you apply for the loan. This can make it more difficult for you to qualify for a mortgage or reduce the loan amount you can afford.
Another point to consider is that some mortgage programs apply applicant income limits. If a co-borrower earns too much money, including them in your application may cause you to exceed the income limit and you may not be eligible for the program. We recommend that you review this point with your lender before you apply for the mortgage.
Lenders Use the Lowest Credit Score Among Multiple Buyers to Determine Your Mortgage Terms
When two people apply for a mortgage as co-borrowers, the lender uses the lower credit score between both applicants to set your loan terms including your mortgage rate. For example, if your score is 740 and your co-borrower’s score is 640, the lender uses the 640 score for your loan application. For some mortgage programs, applicants with a lower credit score pay a higher rate, and vice versa.
Paying a higher mortgage rate increases your monthly payment and potentially reduces the loan you can afford. If the credit score used by the lender is too low, you may be ineligible for certain loan programs. This is why a co-borrower with a good credit score may be helpful while a co-borrower with a low score may be detrimental when you apply for a mortgage.
The table below shows mortgage rates and fees for top-rated lenders near you. We recommend that you contact multiple lenders to confirm the loan you qualify for with a co-borrower and to find the most competitive mortgage terms. Shopping multiple lenders is the best way to save money on your loan.
The Co-Borrower Does Not Need to Live in the Property
As referenced above, you do not need to occupy a property to be a co-borrower on a mortgage -- this is called being a non-occupant co-borrower. Depending on the loan program, however, the lender may limit the debt-to-income ratio for the borrower who lives in the property, which may reduce the maximum mortgage amount you can qualify for. If you are considering having a co-borrower who does not plan to live in the property, make sure to understand how this approach affects the loan you can afford.
Property Ownership Requirements for a Co-Borrower Vary
To take out a mortgage on a property you live in, you are required to hold an ownership interest in the property. Non-occupant co-borrowers are not required to own the property being financed but may do.
If an individual is listed on a mortgage but does not hold an ownership interest in the property, then the individual may technically be a co-signer or guarantor on the loan. Although the difference between a co-borrower and co-signer is somewhat technical, it is important to review this point with your lender when you apply for the mortgage because the qualification guidelines may be different.
In conclusion, a co-borrower for a mortgage can be helpful but it may also be disadvantageous in certain situations. We recommend that you consider all your options -- including applying as a sole borrower or with a co-borrower -- to understand the best way to achieve your mortgage goals.
