What a Cash Out Refinance Actually Costs You
You've got equity sitting in your house and a number in your head, maybe $60,000, maybe $150,000, that you want in your bank account. A loan officer quoted you a rate that sounded fine until you saw the closing costs, and now you're trying to figure out if this actually makes sense or if you're about to pay a fortune to borrow your own money.
Here's the direct answer. A cash out refinance costs you three things: closing costs of 2% to 5% of the new loan amount, a higher interest rate than a standard refinance because lenders price cash out loans separately, and the interest you'll pay on the entire new loan balance for as long as you carry it, not just on the cash you pulled out. On a $400,000 refinance, that's commonly $8,000 to $20,000 in closing costs alone, before you factor in the rate difference.
That's the number people don't see coming. They think about the check they'll get. They don't think about the loan they just signed up to repay for the next 30 years.
How a cash out refinance actually works
You're not borrowing your equity as a separate loan. You're replacing your entire mortgage with a new, bigger one and pocketing the difference in cash.
Say your house is worth $500,000 and you owe $250,000. A lender might let you refinance up to 80% loan to value, so $400,000. You pay off the old $250,000 loan and walk away with roughly $150,000 minus closing costs.
That means your original $250,000 balance, at whatever rate you had, is gone. All $400,000 is now at the new rate, for a fresh 30 year term unless you specifically shorten it.
The closing costs
Lenders charge origination fees, appraisal fees, title insurance, recording fees, and often points. On a $400,000 loan, expect somewhere between $8,000 and $20,000, depending on your state, your lender, and whether you buy down the rate with points.
Some lenders will roll these costs into the loan instead of charging them upfront. That doesn't make them free. It means you're paying interest on your own closing costs for the next three decades.
The rate premium
Cash out refinances carry a higher rate than a rate and term refinance on the same property, usually 0.125% to 0.5% higher, sometimes more if your loan to value is above 75% or your credit score isn't pristine. Lenders price it higher because cash out loans default at higher rates than purchase loans, so they're compensating for risk across their whole portfolio.
That doesn't sound like much until you run it over 30 years.
A worked example
Let's use real numbers. You owe $250,000 at 3.5% with 27 years left. You refinance to pull out $100,000 cash, landing on a new $350,000 loan at a 30 year term.
A cash out refi today might price around 7.25%, against maybe 6.9% for a straight rate and term refinance on the same file. That 0.35% gap sounds small.
Old loan, remaining payments: roughly $1,264/month, and over 27 years that's about $409,000 total, with about $159,000 of that being interest.
New loan, $350,000 at 7.25% over 30 years: payment is about $2,388/month. Over 30 years that's about $859,700 total, with about $509,700 of that being interest.
You took out $100,000 cash. You'll pay roughly $509,700 in interest over the life of the new loan versus $159,000 remaining on the old one, a difference of about $350,700, plus closing costs of maybe $12,000 upfront. You extended the clock too, three extra years of payments on top of a much bigger balance.
That's not a reason to avoid it. It's the actual price tag, and most people never see it laid out because the loan officer's job is to get you to closing, not to run your amortization schedule against the alternative.
What people get wrong
The biggest mistake is treating the cash as free because it's "your equity." It isn't free. You're financing it at your new mortgage rate for up to 30 years unless you pay it down faster. If you use $100,000 to remodel a kitchen or pay off a car, you're financing that kitchen and that car at mortgage terms stretched across three decades, which usually means far more total interest than a shorter personal loan or even a HELOC would cost, even at a higher stated rate.
The second mistake is not comparing against a HELOC or home equity loan. Those keep your original low rate mortgage untouched and only charge interest on the amount you actually draw. A cash out refi resets the rate on your entire balance. If your existing mortgage rate is well below current market rates, a HELOC often costs less overall even with a higher rate on the second lien, because it's not dragging your whole loan up with it.
The third mistake is ignoring loan to value limits and PMI. Most lenders cap cash out refis at 80% LTV on a primary residence. If you cross that, you're often paying private mortgage insurance again, an extra monthly cost that can run several hundred dollars depending on your loan size, on top of everything else.
When it actually makes sense
It makes sense when the money you pull out earns more than the loan costs you, or solves a problem a more expensive form of debt would solve worse. Paying off credit cards at 22% with mortgage debt at 7% is real, calculable savings. Funding a rental property purchase or a value add renovation on an investment property, where the cash you pull out generates income or forces appreciation, can pencil out even after the interest math above.
It makes less sense when it's funding depreciating purchases, when your current rate is well below market, or when you haven't compared it against a HELOC, a home equity loan, or just saving up.
The honest limitation here
I can't tell you your break even point without your actual numbers, your current rate, your credit, your state's closing costs, and what you're doing with the cash. The example above uses realistic figures, not your figures. Run your own amortization schedule, old loan versus new loan, before you sign anything. Any loan officer can print one for you in five minutes, and if they won't, that tells you something.
If you're pulling cash out to fund your next deal, the refinance is only step one. The money still has to land on a property worth buying, and finding that property is where most of these plans actually fall apart.
