Borrower
Definition
The borrower is the person or people who take out the mortgage and are responsible for repayment. More than one borrower can share that obligation. This page describes the consumer role, not every legal form a borrower might take.
In plain English
On a mortgage, someone must be responsible for repayment. That party is the borrower. Couples and other household groups often sign together; each of them is still a borrower. Applying for a loan and being the borrower are close ideas, but they are not always identical. An applicant is asking for credit. A borrower is the party on the loan once it exists. A coborrower is an additional obligated party, not a different kind of debt. This canary does not catalog corporate or trust borrowers. Everyday US Mortgage Index pages are about people taking out home financing.

Why it matters
Credit, debt-to-income ratio, and complaint language attach to a borrower, not to “the house.” Readers need that role before they can read a lender profile or a disclosure.
Example
Sam and Riley both sign the mortgage. Each is a borrower. Their adult child, who only helped gather paperwork and did not sign, is not a borrower on that loan.
