Cash Out Refinance: What It Is, How It Works, and When to Use It

When you do a cash out refinance, a type of mortgage refinancing where you borrow more than you currently owe on your home and take the difference in cash. Also known as equity release through refinancing, it lets you tap into the value your home has built up over time—without selling it. This isn’t just about getting extra cash. It’s about using your home as a financial tool, whether to pay off high-interest debt, fund home improvements, or cover unexpected costs.

But here’s the catch: a cash out refinance, a mortgage replacement that increases your loan balance and resets your repayment term. Also known as refinancing with cash withdrawal, it often means you’ll pay more in interest over time—even if your new rate is lower. You’re not just swapping one loan for another. You’re increasing your total debt, extending your payment timeline, and potentially putting your home at greater risk if things go sideways. That’s why it’s not for everyone. Many people who try it end up deeper in debt, especially if they use the cash for non-essential spending.

Related concepts like home equity, the portion of your home’s value that you actually own, calculated by subtracting what you still owe on your mortgage. Also known as equity in your property, it’s the fuel behind every cash out refinance. The more equity you have, the more you can borrow. But lenders don’t let you take it all. Most cap your new loan at 80% of your home’s value. So if your house is worth £300,000 and you still owe £150,000, you might be able to borrow up to £240,000—giving you £90,000 in cash after paying off your old loan. But that also means you’re now carrying a bigger debt, with higher monthly payments.

And it’s not just about the numbers. Your credit score, a three-digit number lenders use to judge how risky you are as a borrower. Also known as FICO score, it directly affects whether you qualify and what rate you get. A score below 620? You’ll likely be denied—or stuck with a rate that wipes out any savings. Your debt-to-income ratio matters too. If you’re already juggling multiple loans, adding another one could push you over the edge.

Some people use cash out refinance to pay off credit cards. That sounds smart—until you realize you’re turning unsecured debt into secured debt. If you can’t keep up with payments, you don’t just hurt your credit. You risk losing your home. Others use it for home upgrades. That’s smarter. Improvements can raise your home’s value, helping you recoup the cost over time. But if you’re doing it just to fund a vacation or a new car? That’s a trap.

There are alternatives. A HELOC, a revolving line of credit secured by your home, letting you borrow as needed up to a set limit. Also known as home equity line of credit, it gives you flexibility without locking you into a bigger fixed payment. Or you could take out a personal loan. It’s unsecured, so your home isn’t on the line—but the interest rate might be higher. Each option has trade-offs. The key is knowing which one matches your real goal, not just your immediate need.
