Two homeowners can build the identical pool at the identical price and still end up paying very different totals once financing enters the picture. A $60,000 pool financed at roughly 7.2% costs meaningfully less over time than the same $60,000 financed at roughly 12.3%, and that gap has nothing to do with the pool itself. It comes entirely from how the money is borrowed: a home equity line of credit (HELOC), a cash-out refinance, or an unsecured personal loan.

This guide compares what each option actually costs in 2026, where each one fits best, and why the “cheapest” choice usually depends more on your current mortgage rate and how firm your project’s price is than on chasing the single lowest number you can find. If you haven’t settled on a design or a realistic price range yet, our pool installation cost guide is worth reading first, since everything below assumes you already have a rough number in mind to finance.

TL;DR: A HELOC typically offers the lowest closing costs and the most flexibility, since you draw only what you need as pool costs come in. A cash-out refinance can offer a lower rate than a HELOC, but it costs 2-5% of the loan amount upfront and resets your entire mortgage. An unsecured personal loan is the fastest to get, but it carries by far the highest rate. The right choice depends more on your current mortgage rate and how fixed your pool’s final cost already is than on chasing the single lowest number.

The Three Ways Homeowners Actually Pay for a Pool

Most pool buyers who don’t pay cash end up choosing between three financing paths: a HELOC, a cash-out refinance, or an unsecured personal loan. Each one pulls money from a different place, and each carries a different rate, cost structure, and speed to funding.

A HELOC and a cash-out refinance both borrow against your home’s equity, which is why both typically carry lower rates than a personal loan. The difference between the two is structural, not just financial: a HELOC is a separate revolving line of credit sitting on top of your existing mortgage, while a cash-out refinance replaces your entire mortgage with a new, larger one at a new rate. An unsecured personal loan borrows against neither, relying only on your credit profile, which is exactly why it funds fastest and costs the most.

The table below is a starting reference point. Each option gets its own section afterward, with the reasoning behind when it actually fits your situation.

Financing Option Typical Rate Range (2026) Typical Closing Costs Flexibility Best Fit
HELOC 7.17% – 7.44% (CBS News, MidFlorida) $500 – $2,500 (Amerisave) Revolving line; draw and repay as costs come in Pool cost isn’t fully fixed yet
Cash-out refinance 6.77% – 7.01% (CBS News) 2-5% of loan amount; $8,000-$20,000 on a $400K loan (Amerisave) Lump sum; replaces your entire mortgage Today’s mortgage rate beats your current one
Unsecured personal loan 6.2% for excellent credit, 12.28% average (Bankrate) Little to none; some lenders charge an origination fee Lump sum; fastest funding, no home equity needed Need funds fast, or don’t have equity to draw on

HELOC: Best for Flexibility and Uncertain Costs

A HELOC is the right tool when your pool’s final price isn’t fully locked in yet. It works as a revolving line of credit secured against your home’s equity: you draw funds as bills arrive, from the excavation deposit to the final landscaping invoice, pay the balance down, and draw again if a change order adds cost mid-project. That structure matters specifically for pool construction, where site conditions, permit delays, or an added feature can shift the total after the contract is signed.

HELOC rates are currently running around 7.17% to 7.44%, a level multiple rate-forecast sources describe as near three-year lows, according to CBS News and MidFlorida. That’s the same figure we cited in our guide to pool-buying timing, which goes into more detail on why fall 2026 is a reasonable window to plan financing alongside a fall contractor booking.

Closing costs are the other reason a HELOC tends to win on flexibility. Amerisave puts typical HELOC closing costs at $500 to $2,500, a fraction of what a full mortgage refinance requires, because a HELOC doesn’t touch your existing mortgage at all. You keep your current rate on the mortgage itself and layer the line of credit on top of it.

The trade-off is that HELOCs commonly carry a variable rate, so your payment can move if broader interest rates shift during your draw or repayment period. If your pool costs are genuinely fixed by a signed contract and you’d rather lock in one rate for the life of the loan, that variability is worth weighing against the flexibility a HELOC gives you.

Cash-Out Refinance: Best When Today’s Rate Beats Your Current Mortgage

A cash-out refinance is worth considering only when today’s mortgage rate genuinely beats what you’re currently paying. That’s because you’re not adding a new loan on top of your mortgage; you’re replacing the whole thing. That reset is the central trade-off: if refinancing drops the rate on your full mortgage balance, the pool cash-out effectively comes at a very good rate. If it doesn’t, you’re paying refinance closing costs to make a purely lateral move on the rate you already had.

Cash-out refinance rates are currently running around 6.77% to 7.01%, based on late-2025 rate data reported by CBS News, a range that can beat a HELOC’s rate depending on the day and the lender. That’s the appeal: a lower headline rate than a HELOC, on a fixed-rate loan instead of a variable one.

The cost of getting there is the catch. Amerisave estimates cash-out refinance closing costs at 2% to 5% of the total loan amount, which works out to $8,000 to $20,000 on a $400,000 loan. That’s paid upfront, or rolled into the new loan balance, and it applies to your entire new mortgage, not just the portion you’re pulling out to pay for the pool.

Because of that math, a cash-out refinance rarely makes sense purely to fund a pool if your current mortgage rate already beats what’s available today. It makes the most sense for someone who was already planning to refinance anyway, or whose current rate is high enough that a refinance pays for itself independent of the pool. Run the numbers on your existing mortgage rate before assuming a lower advertised percentage automatically means the cheaper option.

Unsecured Personal Loan: Fastest, but the Most Expensive

An unsecured personal loan is the fastest way to fund a pool because it doesn’t touch your home at all. There’s no appraisal, no home-equity requirement, and no risk to your mortgage if you fall behind on payments in a worst-case scenario, since the loan isn’t secured by your house. Funding can land in days rather than the weeks a HELOC or refinance typically requires.

That speed comes at a real cost. Bankrate puts the average personal loan interest rate at 12.28% as of mid-2026, with borrowers who have excellent credit sometimes qualifying for rates as low as 6.2%. We used this same figure in our pool-timing guide, and it’s worth repeating here because the spread matters: even at the best-case 6.2% rate, you’re roughly matching a HELOC or refinance; at the 12.28% average, you’re paying close to double the rate of either home-equity option.

A personal loan makes the most sense when you don’t have enough home equity to qualify for a HELOC or cash-out refinance, when you need the pool funded before home-equity paperwork could realistically close, or when the loan amount is small enough that the rate gap in dollar terms doesn’t matter much. On a large project, that gap adds up fast.

Side-by-Side: Rate, Cost, and Flexibility

Lined up next to each other, the three options separate cleanly by trade-off rather than by one being universally cheaper. HELOCs and cash-out refinances both borrow against home equity and land in a similar, lower rate band. Personal loans sit well above both because they carry no collateral to secure the lender’s risk. Closing costs move in the opposite direction: a HELOC’s costs are the lowest of the three, a cash-out refinance’s are the highest in dollar terms, and a personal loan usually falls in between, often with little to no upfront cost at all.

The Tax Question Nobody Explains Clearly

HELOC and cash-out refinance interest is only tax-deductible when the borrowed money is used to buy, build, or substantially improve the home securing the loan, per IRS Publication 936. A pool typically counts as a substantial improvement, since it’s a permanent addition to the property rather than a personal expense unrelated to the home. That’s the general rule mortgage lenders point to when discussing home-equity borrowing for renovation projects, including pool builds specifically.

The important caveat: this is general guidance, not a determination of your specific tax situation. Whether the interest is actually deductible on your return depends on how the funds are used, whether you itemize deductions at all, current-year loan limits, and rules that can change from one tax year to the next. Confirm your specific situation with a tax professional before assuming any interest will be deductible; nothing in this section should be treated as personalized tax advice.

Unsecured personal loan interest doesn’t carry this potential deduction at all, regardless of what the loan proceeds are used for, since the loan isn’t secured by the home. That’s one more factor tilting the math toward a HELOC or cash-out refinance for borrowers who itemize and can confirm the deduction applies to their situation, though it shouldn’t be the only factor driving the decision.

How to Decide

Start with how certain your pool’s final cost actually is. If you’re still finalizing design details, comparing contractor bids, or building in a buffer for site-condition surprises, a HELOC’s draw-as-you-go structure protects you from borrowing more than you end up needing. You only pay interest on what you’ve actually drawn.

If your project has a signed, fixed-price contract and you’re sitting on a mortgage rate that’s higher than what’s currently available, a cash-out refinance is worth running the numbers on. The math only works in your favor when the new blended rate on your full mortgage genuinely beats your old one. If your current rate is already competitive, the closing costs of a refinance are hard to justify for pool financing alone.

If you don’t have enough home equity to qualify for either option, or you need funds faster than a home-equity process allows, an unsecured personal loan gets the job done, at a rate premium you should budget for from the start.

Before locking in any financing option, it helps to know your actual number rather than a rough guess. Our AI pool design visualizer can show what a specific pool style would look like in your own yard, and our comparison of $50K vs. $100K pool budgets breaks down what each price tier actually buys. Both are worth reviewing before you decide how much to borrow, and through which option.

Frequently Asked Questions

Is a HELOC or personal loan better for a pool? It depends on cost certainty and how fast you need the funds. A HELOC usually costs less over the life of the loan thanks to its lower rate and lower closing costs, and its draw-as-you-go structure fits a pool project whose final cost isn’t fully locked in. A personal loan funds faster and doesn’t touch your home equity, which matters if you don’t qualify for a HELOC or need money before home-equity paperwork could close.

How much does a cash-out refinance cost? Typically 2% to 5% of the total new loan amount in closing costs, or roughly $8,000 to $20,000 on a $400,000 loan, according to Amerisave. That cost applies to your entire new mortgage, not just the portion you’re pulling out for the pool.

What’s the cheapest way to finance a pool? Usually a HELOC, once you combine its rate (around 7.17%-7.44%, per CBS News and MidFlorida) with its lower closing costs ($500-$2,500, per Amerisave). A cash-out refinance can occasionally beat it on rate alone, but only if today’s mortgage rate is meaningfully better than what you’re currently paying, once the higher closing costs are factored in.

Is pool financing interest tax-deductible? Only in specific cases. HELOC and cash-out refinance interest can be deductible when the funds are used to buy, build, or substantially improve the home securing the loan, which a pool typically qualifies as under current IRS guidance. Personal loan interest isn’t deductible under this rule, regardless of how the funds are used. Confirm your specific situation with a tax professional before relying on this for your own return.

The Bottom Line

There’s no single cheapest way to finance a pool that holds true for every homeowner. A HELOC wins on flexibility and closing costs for buyers whose project cost isn’t fully fixed yet. A cash-out refinance can undercut a HELOC’s rate, but only pays off if today’s mortgage rate genuinely beats your current one, once you account for the upfront cost. An unsecured personal loan costs the most over time but gets money in your hands fastest, without touching your home equity at all.
