A HELOC is the most commonly used tool for financing home improvements in the United States — and there's a clear reason for that. You're borrowing against an asset you already own, you only pay interest on the money you actually draw, and you can stage the spending to match how a renovation actually unfolds: contractor deposit first, materials later, final payment at completion.
But "most commonly used" doesn't mean "automatically the right move." This guide gives you the honest picture — which projects make financial sense to fund this way, what the current borrowing cost looks like, and where homeowners go wrong.
Why homeowners use a HELOC for renovations
The short version: it's cheaper and more flexible than almost every alternative for projects above $10,000. But the longer version is worth understanding, because the flexibility is also where most of the risk sits.
When you take a personal loan for a renovation, you borrow a lump sum and begin paying interest on the entire amount immediately — whether you've spent it or not. A HELOC works differently. You're approved for a credit line (say, $60,000) but you only draw what you need, when you need it. During the draw period — typically ten years — you make interest-only payments on whatever you've actually used.
When I renovated my own home in the UK, I took a traditional fixed loan — borrowed a set amount, paid interest from day one on the full sum whether I'd used it or not. No flexibility, no staging. US homeowners with a HELOC have access to something meaningfully better. That difference in structure is exactly why this site exists.
There's also a tax angle. HELOC interest is tax-deductible when the money is used to "buy, build, or substantially improve" the home that secures the line — which a renovation almost always qualifies as. That deduction doesn't apply if you use the HELOC for something else (debt consolidation, holidays, and so on). The IRS rules here are outlined in IRS Publication 936.
Current HELOC rates for 2026
HELOC rates have fallen meaningfully since their 2023–2024 peak. Here's where things stand as of June 2026.
| Source | Average HELOC Rate | Date |
|---|---|---|
| Bankrate national survey | 7.43% | June 3, 2026 |
| Curinos (Yahoo Finance) | 7.25% | June 12, 2026 |
| Experian / Curinos | 7.49% | June 2026 |
| LendingTree (April 2026 avg) | 7.09% | April 2026 |
Sources: Bankrate; Yahoo Finance / Curinos, June 12, 2026; LendingTree.
For context, LendingTree data shows the average rate offered to its customers was 8.46% in April 2025 — meaning rates have dropped by roughly a full percentage point over the past year. The trend has been downward, though most analysts expect the pace of decline to slow.
The averages above are for borrowers with strong credit (typically 780+) and a combined loan-to-value ratio under 70–80%. If your credit score is in the 680–720 range, your rate may sit 1–2 percentage points higher. Shop at least three lenders — rates genuinely vary.
Which home improvement projects have the best ROI
Borrowing to improve your home only makes full financial sense if the improvement either (a) adds more value than it costs, or (b) improves your quality of life enough to justify the interest expense. The 2025 Cost vs. Value Report, published annually by Zonda in collaboration with Remodeling Magazine and the Journal of Light Construction, gives the clearest national picture of resale ROI by project type.
Here are the headline findings from the 2025 edition — the most recent report available.
| Project | Approx. Cost | Resale ROI | Rating |
|---|---|---|---|
| Garage door replacement | ~$4,500 | 268% | Best ROI |
| Steel entry door replacement | ~$2,800 | 180%+ | Best ROI |
| Manufactured stone veneer | ~$11,000 | 208% | Best ROI |
| Minor kitchen remodel | ~$27,000 | 113% | Strong |
| Basement remodel (finished) | ~$60,000+ | 71% | Moderate |
| Major kitchen overhaul (upscale) | ~$155,000 | ~52% | Lower ROI |
| Primary suite addition | ~$175,000 | ~40% | Lower ROI |

The 2025 report confirmed a pattern that has held for several consecutive years: exterior projects dominate the top of the ROI table. Of the ten highest-ROI projects nationally, eight are exterior replacements. Large interior remodels score lower on resale return — though they can deliver enormous value in livability for homeowners planning to stay long-term.
The important distinction: resale ROI vs. quality-of-life value
The Cost vs. Value report answers one specific question: what does this project add to the resale price of your home? It doesn't measure how much more you'll enjoy the space, how much easier mornings become after a bathroom renovation, or how much longer you can stay in a home that now better fits your needs.
If you're planning to sell within two to three years, focus hard on ROI. If you're planning to stay for a decade or more, the quality-of-life calculation matters just as much — and a HELOC can still be a sensible tool to fund it, as long as you're honest about what you're doing.
How the draw period gives you an advantage on renovations
Most HELOCs have a draw period of ten years. During this time you can borrow, repay, and borrow again — up to your credit limit. You only pay interest on what's outstanding at any given moment.
For home improvements, this structure is genuinely useful. A renovation rarely unfolds as a single lump-sum purchase. There's a contractor deposit, then materials, then labour draws at various stages, then finishing costs. With a HELOC you match your borrowing to your spending.
If your kitchen renovation takes four months to complete and you draw the full $40,000 on day one, you pay interest on $40,000 for four months. If instead you draw $10,000 at the start and add funds as the work progresses, your average outstanding balance — and therefore your interest bill — is considerably lower.
After the draw period closes, the HELOC moves into its repayment phase (typically another 10–20 years) and your payment will include both principal and interest. This is where some homeowners get caught out — plan for the step-up in payments before the draw period ends.
Real-world scenario: Jennifer's kitchen remodel
Worked example
Jennifer remodels her kitchen in Phoenix, Arizona
Jennifer owns a home valued at $520,000 with a $310,000 mortgage balance. She's been in the house for seven years and wants to update the kitchen — new cabinets, worktops, and appliances — without moving. The quotes come in at $38,000.
Jennifer's lender will advance up to 85% of her home's value, minus the mortgage: (85% × $520,000) − $310,000 = $132,000 available. She takes a $45,000 HELOC — enough for the kitchen with a small buffer — at a rate of 7.43%.
She draws $10,000 upfront for the contractor deposit, then $28,000 mid-project for cabinets and labour. At the end she draws the final $8,000 for appliances and finishing. Her average balance over the five-month renovation is roughly $23,000 — so her interest cost during construction is around $711 total, not the $1,411 she'd have paid on a $38,000 personal loan at the same rate from day one.
A minor kitchen remodel in Phoenix typically recoups around 113% at resale per the 2025 Cost vs. Value Report. The kitchen is done, she stays in her neighbourhood, her mortgage rate is untouched, and the interest on the HELOC is tax-deductible as it was used to improve the home.
HELOC vs other ways to finance a renovation
| Financing option | Typical rate | Pros | Cons |
|---|---|---|---|
| HELOC | 7.25–7.50% (variable) | Interest-only draw period; draw as needed; tax-deductible for home use | Variable rate; home as collateral; qualification needed |
| Home equity loan | 7.80–8.00% (fixed) | Fixed rate; predictable payments; lump sum | Interest on full amount from day one; less flexibility |
| Cash-out refinance | 6.80–7.20% (fixed) | Can lower mortgage rate; large amounts possible | Replaces existing mortgage; high closing costs; resets loan term |
| Personal loan | 11–16%+ | No collateral; fast approval; fixed payments | Much higher rate; shorter repayment; no tax benefit |
| Credit card (0% intro) | 0% for 12–21 months, then 20–27% | Free money if paid in intro period | Must be paid off; high fallback rate; limited amounts |
If your existing mortgage rate is at or above 7% and you need a large sum (above $100,000), a cash-out refinance at a competitive fixed rate may make more sense than a HELOC. The closing costs are higher, but the simplicity of one payment at a fixed rate can outweigh that over a long time horizon. This is worth a proper side-by-side calculation with real numbers from lenders.
5 mistakes that cost homeowners money
Being approved for $80,000 does not mean you should spend $80,000. Your HELOC limit is the maximum you can borrow, not a renovation budget. Start with a firm project cost and add a 15% contingency. Borrow to that number, not to your limit.
HELOC rates are tied to the prime rate, which moves with Federal Reserve decisions. If rates rise after you draw, your interest payments rise with them. If you're planning a large project, model your numbers at your current rate and at 2 percentage points higher — and make sure both scenarios work for your budget.
Some homeowners open the HELOC, see the funds available, and then get contractor quotes — sometimes accepting the first number they receive. Get three written quotes before you draw a penny. This discipline is far easier to maintain when you haven't yet accessed the money.
It's tempting when you see a credit line with available balance. But if you draw HELOC funds for anything other than home improvement, you lose the tax deductibility on those draws — and you may compromise the financial cushion you need to complete the renovation. Keep the line dedicated to the project it was opened for.
Your interest-only payment during the draw period may be $350/month. When the HELOC moves into repayment (principal + interest over the remaining term), that payment could double or more. Budget for this transition well in advance — ideally before you open the HELOC, not when the letter arrives.
Can you qualify right now?
Lenders typically look for all of the following to approve a HELOC for home improvements:
- Equity: At least 15–20% equity remaining after the HELOC is added (most lenders cap at 80–85% combined loan-to-value)
- Credit score: Minimum 620 at most lenders, though below 680 will mean higher rates and tighter terms; above 740 gets the best pricing
- Debt-to-income ratio: Generally below 43–50%
- Income verification: Two years of tax returns and/or pay stubs
- Property appraisal: Most lenders require a current valuation (some use automated tools; others send an appraiser)

If your home has appreciated since you bought it and your mortgage balance is below 70% of the current value, you're in a strong position to qualify. Use our HELOC calculator to estimate how much you could borrow before you approach any lender.
Frequently asked questions
Is HELOC interest tax-deductible for home improvements?
Yes, if the funds are used to "buy, build, or substantially improve" the home that secures the HELOC, the interest is deductible — subject to the $750,000 total home loan debt limit. If the HELOC is used for anything other than home improvement, the interest is not deductible. See IRS Publication 936 for the full rules.
How much can I borrow for home improvements with a HELOC?
Most lenders will advance up to 80–85% of your home's current value, minus your outstanding mortgage balance. So if your home is worth $400,000 and your mortgage balance is $220,000, you could access up to (85% × $400,000) − $220,000 = $120,000.
What home improvements add the most value?
According to the 2025 Cost vs. Value Report by Zonda and Remodeling Magazine, garage door replacement (268% ROI), manufactured stone veneer (208% ROI), and steel entry door replacement lead the table for resale return. Minor kitchen remodels also perform well at around 113%. Large interior overhauls typically return less on resale, though they can still be worthwhile for homeowners planning to stay long-term.
Can I open a HELOC before I have a contractor confirmed?
Yes — you can open a HELOC and leave it undrawn until you're ready to start. This is actually a sensible approach: it takes 2–6 weeks to get approved, so opening the line before you finalise your contractor means funding is in place the moment you need it. You pay nothing on an undrawn balance at most lenders.
What happens to my HELOC if my home value drops?
Lenders can freeze or reduce a HELOC if they determine that your home value has declined to the point where your combined loan-to-value ratio exceeds their threshold. This is a real risk in a softening market. If you've already drawn funds, the balance you owe is unaffected — but you may lose access to further draws. We cover this in detail in our post: Can a Lender Freeze Your HELOC?
Should I do a HELOC or a home equity loan for a renovation?
For a renovation that unfolds in stages — which most do — a HELOC is typically the better fit. You only pay interest on what you draw. If you know the exact total upfront (e.g. a fixed-price turnkey contract), a home equity loan with a fixed rate offers more payment certainty. The comparison comes down to flexibility vs. rate predictability.
