How a cash-out refinance works
You take out a new mortgage larger than what you currently owe. The new loan pays off your old one, and the remaining amount comes to you as cash at closing.
- An appraisal establishes your home's current value
- The new loan pays off your existing mortgage in full
- You receive the difference as a lump sum
- The new rate and term apply to the whole balance
Unlike a HELOC or home equity loan, there's no second lien — you end up with one mortgage, on new terms.
Where it gets expensive
The catch is scope: the new rate applies to your entire mortgage, not just the cash you pull out. If your current rate is well below today's rates, you give that low rate up on every dollar you already owed.
The rate math that matters Compare today's rate against your existing rate on the full balance — not just against the amount you're borrowing — before you refinance.
Closing costs run about 2–5% of the new loan amount, and the loan term resets — both higher-cost than opening a HELOC or home equity loan.
Is cash-out refinance interest tax-deductible?
Only the portion used to buy, build, or substantially improve the home securing the loan qualifies for the mortgage interest deduction under current federal rules. Cash used for other purposes — paying off credit cards, tuition, a car — isn't deductible, even though it's part of the same mortgage. Check with a tax professional for your situation.
Who a cash-out refinance fits
This option fits borrowers whose current rate isn't worth protecting, or who need one very large sum.
- Current mortgage rate at or above today's rates
- A need for a larger sum than a second lien typically allows
- A preference for one loan and one payment
- No interest in keeping a separate first mortgage
Skip it if your existing rate is well below current rates — a HELOC or home equity loan lets you tap equity without disturbing it.
