Does a HELOC have different rules than a cash-out?

Using a Co-Borrower for Home Equity

Using a Co-Borrower for Home Equity is central to a smooth home equity approval — here are the 2026 rules and numbers.

The rule for 2026

Adding a co-borrower - often a spouse or co-owner - combines incomes and can improve DTI, raising your borrowing limit. The co-borrower shares full responsibility for repayment, and their credit affects approval and pricing. Anyone on the title typically must sign the loan documents.

Lenders set their own overlays on top of the basics. Meet the standard below first, then confirm whether your lender layers anything extra.

Documentation you'll typically need

Recent pay stubs and two years of W-2s or returns
Two months of bank statements
Your current mortgage statement and homeowners insurance
A recent appraisal or automated valuation
