Cash-Out Refinance: When It Beats a Second Lien

How the numbers work

The lender appraises the home, applies a maximum loan-to-value ratio — commonly 80% for conventional loans — and the new mortgage pays off the old balance plus closing costs, with the remainder going to you as cash.

On a $400,000 home with a $220,000 balance and an 80% limit, the new loan is $320,000, and after paying off the old mortgage and costs you receive roughly $90,000-95,000.

The rate trap

The whole balance reprices, not just the cash you take. Refinancing a $220,000 mortgage at a low legacy rate into $320,000 at a higher current rate can add hundreds of dollars a month to the payment on money you already borrowed.

Run the comparison properly: total interest over the remaining term of your current mortgage plus a second lien for the cash, versus total interest on the new consolidated loan. When your existing rate is well below market, the second lien usually wins by a wide margin.

Costs and timing

A cash-out refinance is a full mortgage origination, with the full cost stack.

• Closing costs of roughly 2-5% of the new loan amount, often rolled into the balance.
• A full appraisal, and a new title policy in most states.
• A seasoning requirement — many programmes require six to twelve months of ownership.
• A new amortisation schedule, which restarts the interest-heavy early years unless you shorten the term.

When it is the right call

It works when current rates are at or below your existing rate, when you want to consolidate a first mortgage and an expensive second lien into one payment, or when you need a large sum and prefer a single fixed 30-year payment to a variable line.

Government-backed options change the maths: VA cash-out allows higher loan-to-value ratios for eligible borrowers, and FHA cash-out has its own limits and mortgage insurance costs that need pricing into the comparison.
