Co-Signer

Defined by Onias Derilus, Mortgage Capital · NMLS# 1859012 · Florida licensed mortgage broker

A co-signer guarantees repayment of a mortgage and lends their credit and income to the application, but typically takes no ownership stake.

What Co-Signer means

Unlike a co-borrower, a co-signer usually isn't on the title and doesn't live in the home. They're fully liable if the primary borrower defaults, and the debt appears on their credit report.

Florida example

A Florida parent co-signs so a recent-graduate child can qualify on a starter condo. The parent's strong income covers the DTI gap, but they should understand the loan counts against their own borrowing capacity.

Lending their strength

A co-signer backs your loan with their income and credit but often does not live in the home or hold title. Their strength helps you qualify when your own file falls short.

They are fully on the hook if you miss payments, so it is a serious commitment for them.

When to use one

A co-signer can help a young buyer or someone with thin credit get approved. A parent co-signing for a child is the classic example.

It is a big ask, so weigh it carefully. Reach out and we will tell you whether a co-signer is needed or if another path works.
