Yes, you can have a cosigner on an FHA loan, and FHA rules also allow a non-occupant co-borrower, which is a related but distinct arrangement. Both let a second person’s income help you qualify. Only one of them puts that person on the title. Before you ask a parent or sibling to sign, both of you need to understand which role they are taking, how the lender will combine your finances, and what the cosigner is actually agreeing to.
Cosigner or Co-Borrower — Which One Do You Actually Need
FHA treats these as two different roles. A co-borrower signs the promissory note and the mortgage (the security instrument) and appears on the title, so they share both the debt and the ownership. A cosigner signs only the promissory note. They are fully responsible for repaying the loan but have no ownership stake in the property.1U.S. Department of Housing and Urban Development. What Are the Guidelines for Co-Borrowers and Co-Signers
A co-borrower can be an occupant (they’ll live in the home) or non-occupant (they won’t). The non-occupant co-borrower is the more common setup when a parent is helping a first-time buyer qualify. The eligibility and DTI rules below apply to both cosigners and co-borrowers. The down payment rules depend on the co-borrower’s occupancy and relationship to you.
Who Is Allowed to Cosign
The additional party must be a U.S. citizen or have a principal residence in the U.S. Non-permanent resident aliens can qualify if they hold a valid work authorization document.1U.S. Department of Housing and Urban Development. What Are the Guidelines for Co-Borrowers and Co-Signers
Anyone who financially benefits from the sale — the seller, the builder, the real estate agent — cannot serve as your cosigner or co-borrower. The exception is when that interested party is a family member.1U.S. Department of Housing and Urban Development. What Are the Guidelines for Co-Borrowers and Co-Signers FHA defines family broadly:
- Parents and grandparents, including step- and foster relationships
- Children, stepchildren, adopted children, and foster children
- Siblings and step-siblings
- In-laws (father-, mother-, brother-, sister-, son-, and daughter-in-law)
- Spouses and domestic partners
- Aunts and uncles
Whether the person qualifies as a family member under this list directly changes what you’ll owe at closing.
What a Cosigner or Co-Borrower Does to Your Down Payment
If everyone on the loan will occupy the home, standard FHA financing applies and your minimum down payment is 3.5%. The rules change when the co-borrower will not live in the property.
- Non-occupant co-borrower who is a family member, one-unit property: you keep the standard 96.5% loan-to-value, so 3.5% down.2HUD.gov. FHA Single Family Housing Policy Handbook
- Non-occupant co-borrower who is a family member, two-to-four-unit property: maximum LTV drops to 75%, meaning 25% down.2HUD.gov. FHA Single Family Housing Policy Handbook
- Non-occupant co-borrower who is not a family member: 75% maximum LTV regardless of property type, so 25% down.2HUD.gov. FHA Single Family Housing Policy Handbook
A cosigner (note only, not on title) doesn’t trigger these LTV cuts the way a non-occupant co-borrower does, but many lenders and situations call for the co-borrower structure because it gives the helper a legal interest in the property. Confirm with your lender which role they’re actually setting up.
If the helping family member wants to contribute cash toward your down payment on top of cosigning, FHA allows gift funds from family members for the minimum required investment. The lender will require a gift letter naming the donor, stating the relationship, and confirming no repayment is expected.2HUD.gov. FHA Single Family Housing Policy Handbook
How the Lender Combines Your Finances
The lender pools both parties’ gross monthly income and both parties’ recurring debts, then measures the combined figures against FHA’s debt-to-income thresholds: a 31% front-end ratio (housing payment to income) and a 43% back-end ratio (housing plus all other debts to income). Lenders can go above 43%, and up to roughly 50%, when strong compensating factors are present — significant cash reserves, minimal payment shock, or documented additional income.3HUD. HUD 4155.1 Chapter 4, Section F – Borrower Qualifying Ratios Overview
The cosigner’s debts count. A car payment, an existing mortgage, minimum credit card payments, and student loans all get added to the combined DTI. For student loans showing a zero monthly payment on the credit report — deferred, income-driven, or in forbearance — FHA requires the lender to use 0.5% of the outstanding balance as the assumed monthly obligation.4HUD. Mortgagee Letter 2021-13 Student Loan Payment Calculation of Monthly Obligation A cosigner with heavy existing obligations can drag the ratio in the wrong direction even if their income looks strong on paper.
If the cosigner receives non-taxable income like certain Social Security or disability payments, the lender can gross that income up by 15%, or the person’s actual tax rate if higher, before running the DTI math.2HUD.gov. FHA Single Family Housing Policy Handbook For a retired parent, this can make a meaningful difference.
A Cosigner Won’t Rescue a Low Credit Score
FHA’s minimum credit score is 580 for the 3.5% down payment. Scores from 500 to 579 still qualify but require 10% down. Many lenders set their own higher floors, often 620 or 640.
Here is the part borrowers get wrong. When more than one person is on the loan, the lender takes each person’s middle score from the three bureaus, then uses the lowest of those middle scores as the qualifying score for the whole application.2HUD.gov. FHA Single Family Housing Policy Handbook If your middle score is 560 and your cosigner’s is 780, the lender uses 560, and you’d still need 10% down. A cosigner helps most when income or DTI is the obstacle. If your credit score is the problem, bringing on a cosigner does not solve it.
What the Cosigner Is Actually Agreeing To
A cosigner is fully liable for the debt. If you stop paying, the lender can pursue the cosigner for the entire outstanding balance. Because a cosigner isn’t on the title, they can’t sell the home to recover a loss — only the borrower or a co-borrower on title has that ability.1U.S. Department of Housing and Urban Development. What Are the Guidelines for Co-Borrowers and Co-Signers
The loan appears on the cosigner’s credit report from day one. Late payments get reported under both names. A foreclosure hits the cosigner’s credit as hard as the primary borrower’s and can block them from getting their own mortgage for years. On any future loan application, that FHA mortgage counts as a contingent liability against the cosigner’s DTI.2HUD.gov. FHA Single Family Housing Policy Handbook
There is one built-in relief valve. When a cosigner later applies for a new FHA loan of their own, the lender can exclude the cosigned mortgage payment from the cosigner’s DTI if the primary borrower has made 12 consecutive months of on-time payments and can prove it — bank statements or canceled checks showing the primary borrower is the one paying.2HUD.gov. FHA Single Family Housing Policy Handbook Without that documented 12-month history, the full payment stays in the cosigner’s DTI.
One more cost to be aware of: every FHA loan carries mortgage insurance premiums (an upfront charge of 1.75% of the loan amount and an ongoing annual premium built into the monthly payment). If you put down 10% or less — most FHA borrowers do — the annual premium lasts the life of the loan unless you refinance out of FHA.5U.S. Department of Housing and Urban Development. How Long Is MIP Collected Those premiums are part of the monthly payment the cosigner is guaranteeing.
Getting the Cosigner Off the Loan Later
Once your income and credit can support the mortgage alone, you have a few ways to release the cosigner.
FHA Streamline Refinance
An FHA streamline refinance replaces the existing loan with a new FHA loan. To be eligible you must have made at least six monthly payments, at least six months must have passed since your first payment was due, and at least 210 days must have passed since closing. Your payment history has to be clean: every payment in the last six months made within the month it was due, and no more than one 30-day late in that window. When a streamline is used to remove a borrower, the lender must run credit-qualifying procedures, so the remaining borrower’s income and credit are underwritten to confirm they can carry the loan solo.6FDIC. Streamline Refinance Program Criteria
Assumption with Release of Liability
All FHA-insured single-family mortgages are assumable. If you originally needed a cosigner and now qualify on your own, you can go through a formal assumption in which the lender underwrites you independently and, if you’re approved, issues a release of personal liability that ends the cosigner’s obligation. The cosigner should confirm they receive the official release form (HUD-92210.1) before treating the loan as no longer their problem.7U.S. Department of Housing and Urban Development. Are FHA-Insured Mortgages Assumable
Refinance Into a Conventional Loan
A third route is refinancing into a conventional mortgage in your name only. You’ll need to meet the conventional lender’s standards, but if you have at least 20% equity you also drop FHA’s ongoing mortgage insurance premium in the process.
