Similarities and Differences Between Co-Borrowers and Cosigners
September 2, 2023
What Is a Co-Borrower?
A co-borrower is someone who is listed on the mortgage loan application alongside the primary borrower. They share equal responsibility for repaying the loan and are typically co-owners of the property being financed. During the loan application process they're required to by provide their income details, credit history, and other financial information to help meet the lender's qualification requirements.
Co-borrowers have a legal stake in the property and may have their names on the title and the mortgage documents. FHA loans allow for co-borrowers, including spouses or family members, to combine their incomes and credit profiles to qualify for a larger loan amount or to meet the lender's requirements.
What is a Cosigner?
A cosigner is not typically listed on the mortgage application but can be used in some cases to help the primary borrower qualify for an FHA loan. They're primary role is to provide additional assurance to the lender that the loan will be repaid, and do this by agreeing to assume responsibility for the loan if the primary borrower defaults.
Unlike co-borrowers, cosigners do not have a legal stake in the property being purchased. They don't own or have any rights to the property.
FHA loans are primarily underwritten based on the creditworthiness and financial situation of the primary borrower. In most cases, FHA loans require the borrower to meet the qualifications without the use of a cosigner.
The Bottom Line
The key difference is that a co-borrower is directly involved in the mortgage application, shares equal responsibility for the loan, and has a legal stake in the property, while a cosigner is not directly listed on the application, does not have ownership rights in the property, and provides additional assurance to the lender without being financially involved to the same extent as a co-borrower.
FHA loans are more commonly associated with co-borrowers rather than cosigners, but lending guidelines can vary if a family member is involved. Check with the specific lender for their policies regarding co-borrowers and cosigners on FHA loans.

FHA Loan Articles
June 30, 2026FHA loans offer low down payment options and more forgiving credit requirements for borrowers who may not qualify for a conventional mortgage or need to save more money out of pocket at the front end of the mortgage. But even with more forgiving credit requirements, some borrowers are tempted to omit certain debt information from their home loan applications. What does it mean to conceal a debt or financial situation from your loan officer?
June 30, 2026Some borrowers start working on their credit scores but get impatient with the process because they can't predict when their efforts will change their FICO scores. How long does it take for your FICO scores to update when you pay off a loan, reduce your credit card balances, or take other steps to make yourself a better credit risk? The short answer is that credit reporting procedures are not standardized, and it may take more time than you realize to get those positive credit actions added to your credit report.
June 29, 2026Mortgage interest rates are "moving targets" shaped by national economic trends and the borrower's specific financial profile. What is your FHA loan interest rate? Much depends on the financial data you bring to the table. Lenders set interest rates daily based on a snapshot of market conditions, but the rate ultimately offered also reflects risk, equity, and the lending institution's internal operational costs.
June 28, 2026An FHA appraisal differs from a conventional appraisal. While the goal of a conventional appraisal centers on market value, the FHA appraisal also focuses on the buyer's safety and soundness. FHA lenders select the appraiser, not the home buyer.
June 24, 2026FHA loan closing costs vary by property price and geographic location, rather than by a single nationwide flat fee. Total settlement charges combine percentage-based fees, local government taxes, and marketplace service costs.
