Feeling trapped by a low rate is normal. You locked in 3.25% when rates were near nothing, and now the thought of refinancing into the 6% range feels like giving up your best financial decision. I hear it from Arizona homeowners constantly. This month I helped one of them prove the instinct wrong.
My client moved from 3.25% to 6.99% on a new cash-out refinance — and their total monthly payments dropped by $1,591. That's not a typo. The rate went up; the money going out the door went down, because the mortgage wasn't their only bill. Here's the math, and how to run it on your own debts.
I'm Michael McDermott, a mortgage lender with NEXA Lending (NMLS 184065). I take one application and one credit report, shop roughly 300 lenders, and we look at the whole picture — not just the rate on one loan.
Before you start: gather your latest mortgage statement, every credit-card and loan balance with its APR and minimum payment, and your home's estimated value. Plan for about an hour to run the numbers.
Step 1: Look past the mortgage rate to your total monthly outflow
The rate on your mortgage isn't the whole story. When people compare rates, they usually fixate on one number: the mortgage. But your household doesn't pay one bill. It pays the mortgage plus credit cards, auto loans, personal loans, and anything else carrying a balance.
Credit card rates are commonly north of 20%. Personal loans and auto loans often land well into the double digits, and those balances usually come with short payoff windows, which means large monthly minimums.
So the real question isn't “Is 6.99% higher than 3.25%?” Of course it is. The real question is: what is my total monthly outflow, and what is the blended cost of all my debt?
For my client, the answer was clear. Their high-interest, short-term payments were eating the budget. Rolling them into one mortgage payment — even at a higher mortgage rate — freed up $1,591 every single month.
Step 2: Calculate your blended rate
Your blended rate is the weighted average cost of all your debt — the single number that tells you whether refinancing helps. To find it, for each debt, multiply the balance by its APR, add those products together, then divide by your total debt balance.
For example: $25,000 in credit cards at 22% and $10,000 in a car loan at 8% gives you (25,000 × 0.22) + (10,000 × 0.08) = $6,300, divided by $35,000 = 18% blended. That's the real cost of your money, and it's why a 6.99% mortgage can feel like a bargain.
Success check: Your blended rate should come out meaningfully higher than a current cash-out refinance rate. If it does, debt consolidation is worth a closer look — with the caveats in Step 4 below.
Step 3: Compare a cash-out refinance against a HELOC
A home equity line of credit (HELOC) is often the first thing people ask about, because it lets you keep your low first mortgage. Sometimes that's the right move. But HELOC pricing depends heavily on credit, how much of your home's value you're borrowing against, and the lender. Depending on those factors, HELOC rates can approach double digits. When they do, a HELOC can cost more per month than a fixed-rate cash-out refinance, especially on a larger balance.
Here's how the two options stack up:
Consideration | Cash-out refinance | HELOC |
|---|---|---|
How you get the money | Lump-sum cash from a new, larger first mortgage | A revolving line of credit you can draw from as needed |
Rate structure | Fixed rate, so the payment stays predictable | Often variable, so the payment can rise or fall |
Repayment term | 15–30 year term that may reset your mortgage timeline | 5–10 year draw period followed by a 10–20 year repayment period |
Effect on your first mortgage | Replaces it with a new loan | Sits on top of it as a second loan |
Best for | Large one-time debts or locking in a fixed rate | Flexible or ongoing borrowing without changing your mortgage |
That's why I run both for every client. Sometimes the HELOC wins. Sometimes the cash-out refinance wins by a lot. You won't know until you see them side by side.
Step 4: Weigh the honest trade-offs
A good decision means knowing the full picture, not just the headline savings:
You're spreading short-term debt over a longer term. Lower monthly payments are the goal, but paying debt over 30 years can mean more total interest over time than paying it off fast. Many clients use part of the monthly savings to pay extra toward principal.
There are closing costs. Cash-out refis carry closing costs, often 2–6% of the loan amount. We factor those into the math so the savings are real, not just on paper.
Your home secures the debt. Credit card debt is unsecured. Once it's rolled into your mortgage, it's tied to your house. That's worth taking seriously.
When the numbers and the plan both make sense, this can be one of the strongest financial resets available right now.
A bright spot in a slow market
With purchase activity slow and rates elevated, most mortgage headlines are gloomy. But for homeowners with equity and high-interest debt, this is a real opportunity to lower what goes out the door every month.

1Will I get the same savings as this client?
Not necessarily. Savings depend on your balances, rates, equity, credit, and the loan you qualify for. The $1,591 was one real client's result, not a quote or a promise.
2Is 6.99% the rate I'd get?
No. That was one client's rate on their loan. Your rate, APR, and terms depend on credit, loan-to-value, property, and program.
3How much equity do I need for a cash-out refinance?
It depends on the loan type. Conventional cash-out loans generally let you borrow up to 80% of your home's value, and some government programs work differently. We'll look at what fits your situation.
4Should I do a HELOC or a cash-out refinance?
It depends on the size of the balance, your current first-mortgage rate, and what each option prices at for you. I run both side by side.
5How do I calculate my blended rate?
Take each balance you have, multiply it by its APR, add the results, and divide by your total balance across all debts. If that number is well above today's cash-out refinance rate, consolidation is worth running the full numbers on.
