A cash-out refinance replaces your current mortgage with a larger one and pays you the difference in cash. A HELOC is a separate second line you draw on, and it leaves your first mortgage untouched. Which one costs less usually depends on how your existing rate compares with today’s rates. The six checks below walk through that comparison and what surrounds it. Duane Buziak shows how to run each one with the free comparison tool, using NoTouch Credit Pull, a soft-pull comparison, so shopping does not begin with a hard inquiry.

1. Test the Rate Gap on Your Existing First Mortgage

A cash-out refinance reprices your whole balance, not just the new cash. If your current rate is well below market, you would be paying a higher rate on money that was already cheap. A HELOC borrows only the new amount, so the low first-mortgage rate stays intact. If your rate is at or above market, the refinance has no cheap balance to lose and becomes much more attractive.

Here is a worked illustration, not a quote. Suppose a $500,000 home carries a $300,000 balance at 3.0% (assume a 30-year term), and you need $60,000. The two paths look like this:

• Refinance: a new $360,000 loan at an assumed 6.5% on 30 years is about $2,275 a month.
• Keep and borrow: the existing loan stays at about $1,265, plus an interest-only HELOC of $60,000 at an assumed 8.5%, about $425. Combined, that is about $1,690.

The split path is about $585 a month cheaper, even though the HELOC rate is higher than the refinance rate. Reverse the facts, with a first mortgage at 7.5% and the same refinance quote, and the answer flips.

1. Pull your current rate, balance, and remaining term from your latest statement.
2. Get a refinance quote for the full new balance.
3. Get a HELOC rate for only the new amount.
4. Compare combined monthly payments and upfront costs.

The common mistake is looking only at the new rate and ignoring that a refinance reprices everything. Measure the combined monthly payment and total upfront cost under each path, plus the break-even month if one path costs more up front.

2. Match the Product to the Purpose and Timeline of the Money

A refinance pays out one lump sum at closing and starts charging interest on all of it immediately. A HELOC lets you draw when bills arrive, and interest accrues only on what you have drawn. That difference matters more than the rate when your spending is spread out.

For example, imagine two homeowners who each need $60,000. One signs a single kitchen contract with a deposit and final payment. The other plans a phased remodel paid over 18 months. The first benefits from having the full amount on a predictable schedule. The second would sit on idle cash for months if they took a lump sum, paying interest on money they have not spent.

The reverse risk applies too. A HELOC typically has a draw period followed by a repayment period, and the payment can rise sharply when repayment begins. Terms vary by lender, so confirm the specifics. The CFPB’s consumer guidance on home equity lines of credit explains how draw and repayment periods work.

1. List every expected expense with its approximate date.
2. Total them and note whether you need all the cash at once.
3. Check the HELOC’s draw and repayment periods.
4. Compare those periods with how long you plan to stay in the home.

The mistakes are taking a lump sum for slow costs, or leaning on a HELOC for a long-term need without a repayment plan. Measure the months of interest you would pay on undrawn money and the payment change when repayment starts.

3. Stress-Test Fixed vs Variable Payments

Cash-out refinances are commonly fixed-rate, so the payment is the same every month. HELOCs are commonly variable, tied to an index plus a margin, so the payment moves when the index does. Lenders vary on caps and on whether a fixed-rate conversion option exists, so ask.

Take the earlier illustration. A $60,000 interest-only balance at 8.5% is about $425 a month. If the rate climbs to 10.5%, it is about $525, a $100 swing. That is manageable on a single $60,000 draw, but the swing grows with a larger balance and gets harder to absorb once principal payments begin.

1. Ask for the HELOC’s index, margin, lifetime rate cap, and any fixed-rate conversion option.
2. Calculate the payment at today’s rate.
3. Calculate it again at 2 percentage points higher.
4. Check the stressed payment against your monthly budget, not your best-case month.

The classic mistake is budgeting on the introductory rate only. Some lines start low and reset. Measure the highest payment you can carry comfortably against the stressed payment. If the stressed number is uncomfortable, a fixed-rate refinance, or a HELOC with a fixed-rate conversion option, deserves a closer look.

4. Run the Equity and Loan-to-Value Math Before You Apply

Both products are capped by how much of your home’s value you can borrow against. Combined loan-to-value (CLTV) adds your current balance and the new money, then divides by the home’s value. Higher CLTV usually means tighter eligibility and higher pricing.

Using the same illustration: ($300,000 + $60,000) ÷ $500,000 = 72% combined LTV. That sits inside the 80% cap commonly cited for cash-out refinances on primary residences. Verify the current cap in Fannie Mae’s eligibility guidelines as of the time you apply, since limits and exceptions change.

Loan size matters too. For 2026, FHFA set the baseline conforming loan limit at $806,500, and $1,249,125 in high-cost areas. Check the figure for your county. A refinance that pushes the new balance above your limit becomes a jumbo loan, which can change pricing and documentation. A HELOC sits beside the first mortgage and does not trigger that issue.

1. Get a realistic value estimate, such as a recent appraisal or comparable sales rather than a hopeful guess.
2. Add your current balance and the amount you want.
3. Divide by the value to get your CLTV.
4. Compare it with program caps and the conforming limit for your county.

The common mistakes are an optimistic home value and forgetting that a larger balance can tip a loan into jumbo territory. Measure your CLTV percentage and the margin remaining under the cap. A thin margin means a small appraisal shortfall could change the outcome.

5. Compare Total Cost, Not Just the Advertised Rate

A refinance usually carries closing costs on the full new balance, while a HELOC often has lower upfront fees, though some charge annual or early-closure fees. A headline rate hides all of that. Total cost over the time you will actually hold the loan is the honest comparison.

Continuing the illustration, assume refinance costs of about 3% of the $360,000 new loan, roughly $10,800. The refinance payment runs about $585 a month higher than the keep-and-borrow path ($2,275 versus $1,690). The $10,800 alone equals about 18.5 months of that gap. In this scenario the split path is ahead from day one. Break-even analysis earns its keep when the refinance does lower your payment: divide upfront cost by monthly savings to see when you recoup it.

One caution on the numbers: the interest-only HELOC payment is not directly comparable to a fully amortizing mortgage payment, and a refinance also resets your term. Compare principal paid down as well as monthly cash flow.

1. Request a Loan Estimate for the refinance.
2. Get the HELOC’s full fee schedule, including annual fees and early-closure terms.
3. Total payments and fees over your expected holding period.
4. Note any difference in principal paid down.

The common mistake is comparing a HELOC rate with a mortgage APR as if they were measured the same way. A mortgage APR folds in certain fees, while a HELOC’s rate typically does not. Measure total cost over your holding period and the break-even month.

6. Compare Both Options Across Lenders with a Broker, Not a Single Shelf

A direct lender can only offer what is on its own shelf. As a broker, Duane Buziak can price a refinance across hundreds of wholesale lenders, so the comparison reflects far more than one institution’s pricing. NoTouch Credit Pull keeps early shopping to a soft pull, so you can compare without a hard inquiry on your report.

For example, imagine a homeowner holding one refinance quote from the company that services their current mortgage. They use Dare to Compare so Duane can line that quote up against other wholesale options on rate, APR, and costs. The comparison is then specific to their numbers, not a generic rate table.

1. Start a NoTouch Credit Pull comparison on Free Mortgage Search by Duane Buziak.
2. Upload any existing quote for Dare to Compare.
3. Review the options side by side before deciding.

The common mistake is taking the first quote because it came from whoever holds your current mortgage. Measure the spread in APR and total costs between quotes, and count your hard inquiries. The target is none until you choose.

Eight Questions Homeowners Ask About Cash-Out Refinances and HELOCs

What is the difference between a cash-out refinance and a HELOC?

A cash-out refinance replaces your first mortgage with a larger one and pays you the difference. A HELOC is a second line of credit that sits beside your first mortgage and leaves it in place.

Which is cheaper?

It depends on your existing rate. If your first mortgage rate is well below today’s rates, borrowing separately often costs less. If your rate is at or above market, a refinance can make sense. Neither is cheaper in every case.

Is a HELOC rate always higher than a refinance rate?

Often, but not always, and it varies by lender and market. A HELOC is typically variable and a refinance is typically fixed, so compare total cost rather than rate alone.

Do closing costs differ?

Usually. A refinance carries closing costs on the whole new balance, while HELOC fees are often lower but can include annual or early-closure charges. Ask about no-out-of-pocket closing options where available, and read the Loan Estimate.

How much equity do I need?

Cash-out refinances commonly cap at 80% loan-to-value on primary residences, as of this writing. Check the current Fannie Mae guidelines, since caps and exceptions change.

Can a cash-out refinance push me into a jumbo loan?

Yes. If the new balance exceeds your county’s conforming limit, the loan is jumbo. The 2026 baseline is $806,500, and $1,249,125 in high-cost areas, per FHFA.

Does comparing options hurt my credit?

Not with NoTouch Credit Pull. It is a soft-pull comparison, so early shopping does not add a hard inquiry. A hard pull comes only when you choose to move forward.

Can I compare an offer I already have?

Yes. With Dare to Compare, you share an existing quote and Duane Buziak lines it up against wholesale options on rate, APR, and costs.

Which Checks to Run First, and What Comes After

Start with the rate gap and loan-to-value. Those two checks decide whether a refinance is even viable, and they take about ten minutes with your latest mortgage statement and a realistic home value. Next, work through total cost and rate type, since they determine which viable option is actually cheaper and whether you can live with the payment. Comparing across lenders comes last, because it sharpens numbers you have already framed.

NoTouch Credit Pull and Dare to Compare make that last step low-pressure: you see options side by side, with no hard inquiry until you decide. Your dream home is within reach.
