How it works
A non-occupant co-borrower signs the mortgage with you but doesn't live in the home. Lenders add their income and debts to yours when they figure your debt-to-income ratio. People often call this person a co-signer, but on a mortgage they're usually a full co-borrower, which matters for their risk.
Rules by loan type
Program rules change, so confirm the details with your loan consultant. In general:
- Conventional: often allowed, with rules on how much the occupying borrower must qualify for on their own in some cases
- FHA: often allowed, and a family member may be required for the lowest down payment
- VA: generally not used the way it is with conventional or FHA loans
What lenders review
The co-borrower applies alongside you. Expect the lender to check their credit, income, assets and debts, including their own mortgage. Their monthly obligations count too, so a co-borrower with a large housing payment of their own may add less than you'd think.
The risk for the person helping
Being a co-borrower is a big commitment. If payments are late, it can hurt both of your credit scores. The loan also counts as their debt, which could make it harder for them to get their own loan later. Talk openly about what happens if money gets tight or if one of you wants out.
Title and ownership
Whether the co-borrower goes on the title depends on the loan program and your choice. Being on title gives them an ownership share. Being only on the loan gives them the debt without the ownership. A real estate attorney can explain what each means where you live.
Getting off the loan later
A co-borrower usually stays on the mortgage until it's paid off or refinanced. Once your income and credit can support the loan on their own, refinancing into your name alone is the common way to release them.
Before you apply, talk about the plan for that day. Agreeing early on a target date to refinance, or on what happens if you sell, keeps expectations clear for everyone.
