Home Equity Loans: Why a Second Lien Usually Beats a Cash-Out Refinance
A cash-out refinance re-prices your entire mortgage at today's rate. A home equity loan prices only the new money. When your first mortgage is below market, that difference is the whole decision.

There is one fact that decides most home equity borrowing and almost never appears in the comparison: a cash-out refinance replaces your existing mortgage, so the new rate applies to the whole balance, not just the money you are borrowing. If you are sitting on a 4.25% first mortgage and today's rate is 6.90%, taking $60,000 out through a refinance means re-pricing $290,000 of debt you were perfectly happy with.
A home equity loan or line of credit sits behind the first mortgage instead. Its rate is higher, second lien, higher risk, so 8% to 9% rather than 6.90%, but it applies only to the new money. Which one wins is arithmetic, and once a first mortgage is meaningfully below market, the second lien wins by a wide margin.
How much you can actually borrow
The comparison that decides it
| Home equity loan | HELOC | Cash-out refinance | |
|---|---|---|---|
| What happens to your first mortgage | Untouched at 4.25% | Untouched at 4.25% | Replaced at 6.90% |
| New debt | $60,000 at 8.75% fixed, 15 yr | $60,000 drawn at 8.00% variable | $350,000 at 6.90% fixed, 30 yr |
| First mortgage payment | $1,427 | $1,427 | — |
| New payment | $600 | $400 interest-only, then ~$727 | $2,305 |
| Total monthly | $2,027 | $1,827 rising to $2,154 | $2,305 |
| Versus the cheapest option | +$200 | Cheapest initially | +$478 a month |
| Rate risk | None. Fixed | Variable, tied to prime | None. Fixed |
| Closing costs | $0–2,000, often waived | $0–1,500, often waived | 2–3% of $350,000 = $7,000–10,500 |
| Amortisation clock | First mortgage keeps its schedule | Same | Reset to thirty years |
The cash-out refinance costs $478 a month more than the HELOC and $278 more than the fixed home equity loan, while also charging $7,000 to $10,500 in closing costs and restarting the amortisation clock. The effective rate you are paying on the incremental $60,000 through the refinance route is well into double digits, because the extra cost is really the re-pricing of $290,000 of existing debt.
Home equity loan versus HELOC
| Home equity loan | HELOC | |
|---|---|---|
| Structure | Lump sum, fixed rate, fixed term | Revolving line, variable rate |
| Rate basis | Fixed at closing | Prime plus a margin, moves with prime |
| Typical term | 5 to 30 years, 15 common | 10-year draw, then 15–20-year repayment |
| Payment during draw | n/a. Amortises from day one | Often interest-only |
| Payment after draw | Unchanged | Jumps to fully amortising. The shock |
| Best for | A known amount: a renovation with a quote, a consolidation | An unknown or staged amount: a project in phases, a reserve line |
| Draw flexibility | None. One disbursement | Draw, repay, redraw during the period |
| Rate risk | None | Full exposure. A 2% rise on $60,000 is $100 a month |
| Fixed-rate option | Inherent | Some lenders allow locking portions of the balance |
The interest-only draw period is where HELOC borrowers get caught. Ten years of interest-only payments on $60,000 at 8% is $400 a month and leaves the full $60,000 outstanding. When repayment begins over fifteen years, the payment rises to roughly $573, and if prime has risen in the meantime, considerably more. Plan for the repayment payment from the start, not for the draw payment.
What the money is for changes whether it is a good idea
| Use | Verdict | Why |
|---|---|---|
| Substantial home improvement | Strongest case | Interest may be deductible, and the work can add value to the collateral. Kitchens, additions, roofs, systems |
| High-interest debt consolidation | Good, with one condition | Moving 24% card debt to 8.75% is a real saving, but only if the cards are then closed or left unused. Re-running the balances turns one debt into two |
| Bridging a home purchase before a sale | Reasonable | A HELOC as a short-term bridge is cheaper than most bridge loans, provided the sale is genuinely likely |
| Education costs | Depends | Cheaper than private student loans, but federal student loans carry protections. Income-driven repayment, forbearance. That home equity does not |
| Emergency reserve | Acceptable as a backup | Cheap to keep open, but the line can be frozen exactly when values fall. Not a substitute for cash |
| Investing the proceeds | Poor | You are borrowing at a fixed cost against your home to chase an uncertain return. The downside is the house |
| A car, a holiday, a wedding | Poor | Attaching a 15-year secured lien to a consumable is how a good month becomes a decade of payments |
Interest deductibility follows the use of the funds, not the type of loan. Since 2018, home equity interest is generally deductible only when the borrowing buys, builds or substantially improves the home securing it, and only if you itemise. Consolidating credit cards with a HELOC does not produce deductible interest, whatever the marketing implies.
The risk, stated plainly
- Rates are dramatically lower than unsecured borrowing, 8% to 9% against 20% or more on credit cards.
- A second lien leaves a below-market first mortgage intact, which is frequently worth more than the rate difference on the new money.
- Closing costs are often waived entirely, against $7,000 to $10,500 on a cash-out refinance.
- A HELOC's draw flexibility fits staged projects, where you pay interest only on what you have actually used.
- Interest may be deductible when the funds substantially improve the home, subject to itemising.
- Approval is generally faster and less document-heavy than a full refinance.
- The house is the collateral. Missed payments can lead to foreclosure on a debt that started as a kitchen or a credit-card balance.
- Consolidating unsecured debt into a home lien removes the protections unsecured debt carries, and the option of bankruptcy discharge on that portion.
- A HELOC's variable rate can rise substantially, and the interest-only draw period ends in a step change in the payment.
- Lenders can freeze or reduce a line if values fall, which undermines its use as an emergency reserve.
- Borrowing to 85% or 90% combined loan-to-value leaves little margin if the market falls. You can be unable to sell without cash.
- Interest is not deductible for most uses, and not at all for households taking the standard deduction.
VerdictIf your first mortgage is below current market rates, take a second lien and leave it alone. The arithmetic is not close. Choose the fixed home equity loan for a known amount and the HELOC for a staged one, and in either case underwrite yourself: could you carry this payment through a job loss, given the house is the collateral?
The order to work through this in
Establish your realistic capacity before applying anywhere
Value × 0.85, minus the existing mortgage balance. Use a conservative valuation, comparable recent sales, not an automated estimate at the top of the range. Applying for more than the arithmetic supports wastes a credit pull.
Write down your current first mortgage rate
This single number decides between a second lien and a cash-out refinance. Below today's market rate, the second lien wins. At or above it, price the refinance properly.
Quote both product types at three lenders, including a credit union
Credit unions are consistently competitive on second liens and frequently waive costs outright. Ask each for the rate, the margin over prime for a HELOC, the draw and repayment periods, annual fees, and the early-closure recapture period.
Compute the HELOC's repayment-period payment, not its draw payment
Take the amount you expect to owe when the draw ends and amortise it over the repayment term at a rate 2% above today's. If that payment does not fit comfortably, take the fixed loan instead.
Decide what happens to the debt you are paying off
If you are consolidating cards, close them or remove them from your wallet the same week. This is the step that determines whether consolidation is a solution or an intermission, and it has nothing to do with the loan terms.

The rate on a home equity loan looks worse than a cash-out refinance and usually is not, because the refinance quietly re-prices every dollar you already owed.
Frequently asked questions
- Is a home equity loan better than a cash-out refinance?
- It depends entirely on your current mortgage rate. A cash-out refinance replaces your whole mortgage at today's rate, so if you hold a below-market first mortgage you are re-pricing debt you were happy with. In the worked example, borrowing $60,000 cost $2,027 a month via a second lien against $2,305 via a refinance, plus $7,000 to $10,500 in closing costs. If your existing rate is at or above market, the refinance becomes the better option.
- How much can I borrow against my home?
- Take your home's value, multiply by the lender's combined loan-to-value limit. Usually 80% to 85%, occasionally 90%, and subtract your existing mortgage balance. On a $480,000 home with $290,000 owed, an 85% limit gives $118,000 and an 80% limit gives $94,000. Use a conservative valuation, since an optimistic one is the most common reason approvals come back smaller than expected.
- What is the difference between a home equity loan and a HELOC?
- A home equity loan is a lump sum at a fixed rate over a fixed term, amortising from day one. A HELOC is a revolving line at a variable rate tied to prime, with a draw period of about ten years. Often interest-only, followed by a repayment period of fifteen to twenty years. The fixed loan suits a known amount; the line suits a staged or uncertain one, at the cost of rate risk and a payment step-up when the draw ends.
- Is home equity loan interest tax deductible?
- Only when the borrowed money buys, builds or substantially improves the home securing the loan, and only if you itemise deductions. Using a HELOC to consolidate credit cards or fund a car does not produce deductible interest regardless of the loan type. With the standard deduction where it now sits, most households get no deduction at all, so do not build one into your comparison without checking your own position.
- Can my lender freeze my HELOC?
- Yes. Most agreements allow the lender to suspend or reduce further draws if the property's value falls significantly or your credit deteriorates. This is worth knowing if you are keeping a line open as an emergency reserve, because the circumstances that would trigger the emergency. A recession, a regional downturn. Are the same ones that would trigger the freeze. A line is a useful backup, not a substitute for cash.
- Is it a good idea to consolidate credit card debt with home equity?
- The arithmetic is compelling, 8.75% against 24%, but it converts unsecured debt into debt secured by your house, which means a job loss now threatens the home rather than your credit score. It works when the cards are closed or genuinely stopped, and fails when the balances rebuild alongside the new lien. The loan terms are the easy part; the behaviour change is the part that decides the outcome.
