Once you've built up meaningful equity in your home, three different lenders will happily offer you three different ways to borrow against it, and each one will insist theirs is the obvious choice. A home equity line of credit, a cash-out refinance, and a personal loan all get you cash, but they get it to you through completely different mechanics, with different rates, different risks, and different consequences for the mortgage you already have.
Picking between them by comparing headline interest rates alone is how people end up with the wrong option for their actual situation. The right choice depends on how much you need, how long it will take you to pay it back, and whether you're willing to put your house up as collateral for money that might have nothing to do with your house at all.

What Each Option Actually Is
A home equity line of credit works like a credit card secured by your house: you get approved for a credit limit based on your equity, then draw against it as needed during a set draw period, paying interest only on what you've actually used. A cash-out refinance replaces your entire existing mortgage with a new, larger one, handing you the difference in cash at closing. A personal loan is unsecured, a lump sum based on your income and credit profile, with no lien on your home at all.
The Wikipedia entry on home equity lines of credit lays out the mechanics well: a HELOC is fundamentally revolving debt, while a cash-out refinance and a personal loan are both installment debt, paid down on a fixed schedule from day one.
How the Interest Rates Really Compare
HELOCs typically carry variable rates tied to a benchmark like the prime rate, which means your payment can climb if rates rise during your draw period. Cash-out refinances usually land close to standard mortgage rates, since the whole loan is secured by your home and priced accordingly. Personal loans sit highest of the three almost every time, because the lender has no collateral to fall back on if you stop paying.
Your actual rate on any of the three depends heavily on credit score, and the gap between a strong score and a mediocre one is often larger than the gap between loan types. Checking where you stand before applying, through a resource like myFICO, tells you more about your likely rate than any general comparison chart will.
Closing Costs and Fees You Can't Ignore
A cash-out refinance carries full mortgage closing costs, typically 2 to 5 percent of the entire new loan amount, not just the cash-out portion, since you're replacing your whole mortgage. A HELOC usually has lower upfront costs, sometimes an origination fee and an annual maintenance fee, but rarely the full closing-cost package. A personal loan often has the lowest upfront cost of the three, sometimes no origination fee at all, though that savings gets eaten by the higher interest rate over time.
The Consumer Financial Protection Bureau publishes plain-language breakdowns of what closing costs actually cover, which is worth reading before you assume a "no closing cost" offer is genuinely free rather than rolled into your rate.
What Happens to Your First Mortgage
This is the part people underestimate most. A cash-out refinance doesn't add a new loan alongside your existing mortgage, it replaces it entirely. If you currently have a low fixed rate from a few years back, refinancing resets that rate to whatever's available today, which can cost you more over the life of the loan than the cash-out itself saves you. A HELOC and a personal loan both leave your first mortgage completely untouched.
That single fact eliminates cash-out refinancing for a lot of homeowners the moment they actually run the numbers, since giving up a below-market rate on a $300,000 mortgage rarely pencils out against pulling $30,000 in equity.
Flexibility: Draw Now vs. One Lump Sum
A HELOC's revolving structure is genuinely useful when you don't know your total cost upfront, a renovation project where the scope might expand, or a series of expenses spread across a year. You draw what you need, when you need it, and interest only accrues on the drawn balance. A cash-out refinance and a personal loan both hand you everything at once, which is simpler to plan around but less forgiving if your actual need turns out to be smaller, or larger, than you estimated.
That upfront lump sum also creates temptation. Money sitting in a checking account gets spent differently than a credit line you have to actively draw against, and it's worth being honest with yourself about which structure fits your own spending discipline.

Tax Deductibility Rules You Need to Get Right
Interest on a HELOC or a cash-out refinance is only deductible under current federal rules if the borrowed funds are used to buy, build, or substantially improve the home that secures the loan, not for debt consolidation, tuition, or a vacation. The IRS publishes specific guidance on this, and it's a common enough point of confusion that people assume any home-secured borrowing is automatically deductible when it isn't.
Personal loan interest, by contrast, is essentially never deductible regardless of what you use the money for. If deductibility genuinely matters to your math, the intended use of the funds, not just the loan type, is what determines whether you qualify.
Risk: What You're Actually Putting on the Line
A HELOC and a cash-out refinance are both secured by your home, which means missed payments can eventually lead to foreclosure. A personal loan is unsecured, so a default damages your credit and can lead to collections or a judgment, but it doesn't put your house directly at risk. That difference is the real trade-off underneath the rate comparison: you're not just choosing a price, you're choosing what happens in the worst case.
This is exactly the kind of decision worth running through actual numbers rather than gut feel. EvvyTools' Home Equity Loan Comparison tool models all three options side by side using your own credit profile, showing monthly payments, total interest, closing costs, and a break-even timeline instead of leaving you to eyeball three different rate quotes against each other.
A Real Walkthrough: Comparing $50,000 Three Ways
Say you need $50,000 for a mix of home improvements and a bit of debt consolidation. A HELOC at a variable rate might start you around a lower monthly payment during the draw period, interest-only, but that payment climbs once you enter repayment and start paying down principal too. A cash-out refinance folds the $50,000 into a new 30-year mortgage, spreading it out at a lower rate than the HELOC's likely ceiling, but you're paying closing costs on your entire remaining balance, not just the new $50,000.
A personal loan for the same $50,000, fixed over five to seven years, gives you the most predictable payment and the fastest full payoff, but at a rate that can run several points higher than either home-secured option. Run your specific numbers, your actual balance, your actual credit score, your actual timeline, through the comparison tool rather than these rough illustrations, since a few points of rate difference on $50,000 compounds into a meaningfully different total cost.

Which Option Fits Which Situation
A HELOC tends to fit best when your total cost is genuinely uncertain up front, an open-ended renovation, a series of home repairs discovered as you go, or a financial cushion you want available without paying interest until you actually draw on it. A cash-out refinance fits best when current mortgage rates are at or below what you're already paying, so you're not sacrificing a good rate to access equity, and you need a large, defined amount for something with a long payoff horizon.
A personal loan fits best when the amount is smaller, you want the fastest possible full payoff, or you'd rather not put your home on the line at all for whatever you're borrowing for, even at the cost of a higher rate. None of these is universally "the best" option, they're built for different situations, and applying for the wrong one is often about skipping the comparison step entirely.

Common Mistakes People Make Comparing These Three
The most common mistake is comparing only the interest rate and ignoring the closing costs entirely, which is exactly how a cash-out refinance ends up looking cheaper than it actually is over a five-year horizon. The second most common mistake is applying for a HELOC without checking what happens to the rate once the draw period ends and repayment begins, since a lot of homeowners are surprised when their "cheap" line of credit payment jumps.
A third mistake is treating a personal loan as automatically worse just because the rate is higher, without factoring in that you're not risking your home to get it. Freddie Mac is a useful, lender-neutral reference for understanding how mortgage-secured products are structured before you compare them against something unsecured. The rate alone never tells the whole story, and skipping the total-cost comparison is the single most expensive shortcut in this whole decision.
A fourth mistake, subtler than the first three, is assuming your credit score from six months ago still applies. Rates on all three products are re-priced against your current profile at the time you apply, and a score that's drifted since your last check can shift which option actually comes out cheapest.
A fifth mistake is applying to only one lender per option and assuming the quote you got is representative. Rate spreads between lenders on the same HELOC or the same refinance amount can run wider than the gap between two different loan types entirely, so a single quote tells you less than people assume it does.
Making the Final Call
The mistake most people make isn't picking the wrong loan type, it's not comparing all three against their actual numbers before applying for any of them. A rate that looks great on a bank's homepage might be the worst option once you factor in closing costs, what happens to your existing mortgage, and how long you'll actually be carrying the balance.
