Chase Slate®'s long interest-free purchase window, compared with borrowing against your house for a fixed-cost project.
November 5, 2026
Ask any finance expert about the best ways to pay for a home renovation, and the advice typically defaults to one of two options — cash in hand or a home equity line of credit (HELOC). While that may be reasonable advice for a $60,000 kitchen gut renovation, it's often the wrong default for an $8,000 bathroom refresh or $15,000 new roof. In either case, that's a fixed-cost project with a payoff timeline most households could realistically hit in under two years. This means another option could make sense — and could save you from paying any interest at all.
A 0% APR credit card could be worth considering, even though these cards are mostly known for offering long 0% APR windows on balance transfers. Citi® Diamond Preferred, for example, offers consumers 0% Intro APR on balance transfers for 21 months and on purchases for 12 months from date of account opening. After that the variable APR will be 16.74% - 27.49%, based on your creditworthiness. Balance transfers must be completed within 4 months of account opening. (See Rates & Fees). That means you have plenty of runway for debt you're moving over, not much for financing a new project from scratch. A renovation is a purchase, not a transfer, so the purchase-APR window is the number that actually matters here, and it's the number most 0% APR coverage skips past on its way to the balance-transfer headline.
The Chase Slate® is one of the few widely available cards where you get the same intro rate and length ( 0% intro APR for 21 months on Balance Transfers — See Rates & Fees) on both purchases and balance transfers. That's what turns it into something other than a pure debt consolidation tool — a way to finance a fixed-cost renovation interest-free, without putting your home up as collateral or waiting out a multi-week underwriting process.
According to recent data from Harvard University's Joint Center for Housing Studies, annual household spending on home renovation projects is expected to reach $518 billion by the end of 2026.
Most "best 0% APR card" roundups are built around one stat only — how long the balance transfer offer runs. That makes sense for content aimed at people who need to consolidate existing debt, which is the majority of that search demand. But it means the purchase-APR length — a separate spec that happens to match the transfer window on some cards and badly trail it on others — rarely gets its own spotlight, even for readers who have nothing to transfer and just want to finance something new.
That's a real gap for anyone financing a specific purchase rather than moving around old debt. A home renovation project, large appliance purchase, or medical bill charged directly to the card all fall into this second category, and the card that wins for a debt consolidation isn't automatically the card that wins here.
Chase Slate®'s 0% Intro APR runs for 21 months on Purchases from account opening — not 21 months on Purchases from the date of each individual purchase. That distinction matters for timing a renovation. After all, a purchase made in month one of the account gets the full 21-month runway, while the same purchase made in month ten only gets whatever is left of the intro period. If you're planning to open the card specifically to finance a project, the math works best when the bulk of the spending happens soon after account opening.
Beyond the APR itself, the purchase side of this card is straightforward. There's no annual fee, and — because it's a purchase rather than a balance transfer — balance transfer fees won't apply. Zero Liability Protection also covers fraudulent charges, which is worth having on a card carrying a five-figure renovation balance.
Unfortunately, using credit cards for renovation projects isn't always "free."
Credit expert John Ulzheimer, formerly of FICO and Equifax, says most contractors charge a small fee for using credit cards since "the cost of home improvements can be considerable." With that in mind, you can always ask to pay for materials directly with credit, then pay the fee only on labor itself.
You're certainly open to negotiating or splitting the payments, but I'm not sure how successful you'll be in avoiding the surcharge. They've become almost a standard.
A HELOC is a revolving line of credit secured by your home equity. According to the Consumer Financial Protection Bureau (CFPB), it works in two phases: a "draw period" — often up to 10 years — during which you can borrow repeatedly up to your credit limit, followed by a separate repayment period where you pay down the remaining balance, sometimes over 10 to 20 more years. HELOCs almost always carry a variable interest rate, so payments will fluctuate based on the current rate in addition to how much you have borrowed.
That variable rate is typically calculated as the prime rate plus a margin set by the lender based on your credit and loan-to-value ratio. The prime rate stood at 6.75% as of the Federal Reserve's August 26, 2026 H.15 release — meaningfully higher than a card's 0% intro rate, though usually lower than the card's regular rate once the intro period ends.
Getting a HELOC also takes longer and involves more steps than opening a credit card. Chase's own consumer-education materials put the typical timeline at two to six weeks from application to funding, which includes time required for a property appraisal, underwriting, review of income and debt-to-income ratio, and a closing process where the lender discloses fees before you sign. And because the loan is secured by the value of your home, it's possible to lose your property to foreclosure if you fail to repay the money.
One factor that can favor a HELOC for larger projects is the potential to save money on taxes. According to IRS Publication 936, interest on a home equity loan or HELOC can be tax-deductible when the funds are used to "buy, build, or substantially improve" the home securing the loan — subject to itemizing your deductions and the $750,000 total mortgage-debt limit. A 0% APR card offers no comparable deduction, since there's no interest being paid during the intro period to begin with.
This is general information, not tax advice — talk to a tax professional about how this applies to your specific situation.
Feature | 0% APR Purchase Card (Chase Slate®) | HELOC |
|---|---|---|
Time to access funds | Typically available within days of approval | Typically 2–6 weeks from application to funding |
Collateral | None | Your home |
Rate while paying it down | Enjoy 0% Intro APR for 21 months on purchases and balance transfers, then a variable APR of 18.49% - 28.49% thereafter | Variable, tied to the prime rate (6.75% as of August 2026) plus a lender margin |
Upfront costs | $0 — no annual fee; balance-transfer fee doesn't apply to purchases | Appraisal and other closing costs, disclosed by the lender before you sign |
Repayment structure | Minimum monthly payments during the intro period, full flexibility to pay faster | Draw period (often up to 10 years), then a separate repayment period, per the CFPB |
Best suited for | A fixed, moderate project payable within about 18 months | A larger project, a longer payoff timeline, or when a lower long-run rate matters more than speed |
The project cost fits comfortably under your credit limit and you can realistically pay the balance off within around 18 months.
You'd rather not put your house up as collateral for a moderate expense.
You want funds essentially right away rather than waiting out a multi-week appraisal and underwriting process.
You're paying for your project in one or two lump sums rather than drawing repeatedly over an extended period.
You won't need cash to pay for your home renovation, and can easily use a credit card to fund the project.
The project cost exceeds what you could responsibly put on a card, or exceeds your credit limit.
You expect the payoff to run longer than the card's intro window and want a materially lower ongoing rate than the card's post-intro APR.
You're financing a series of projects over time and want a reusable line rather than a one-time purchase.
You expect to claim the mortgage-interest deduction for a qualifying improvement and the deduction is a meaningful part of your math (again, confirm the details with a tax professional).
You want to be able to pay for at least part of your project with cash.
Before you use a 0% APR credit card to finance a home renovation project, you should make sure you have a solid plan for how you'll pay back the money.
Eric Pemper of debt consolidation company CuraDebt says a common mistake is focusing only on the length of the 0% offer without considering the monthly payment needed to eliminate the balance before the promotional period ends.
Divide the transferred balance plus any fee by the number of promotional months.
If the monthly payment you'll need to make to pay off the balance isn't realistic, you should look for other ways to pay for your home renovation.
If that number doesn't fit your budget, either the project needs to shrink, the timeline needs to stretch — which likely means a HELOC's amortized structure is the better fit — or both.
In addition, you'll want to make sure you understand how either type of financing might impact your credit. John Ulzheimer points out that HELOC balances are not considered in credit utilization metrics. This means large balances won't lower your scores.
However, the same can't be said for credit card balances. If you apply for a 0% APR credit card and immediately run up a large balance, you may see a drop in your credit score until the balance drops below 30% of your available credit limits. After all, the Consumer Financial Protection Bureau (CFPB) recommends keeping your credit utilization below 30% for the best credit score results.
Does charging a renovation to a credit card hurt my credit score?
It can, temporarily, if the charge pushes your credit utilization on that card (or across your accounts) up significantly. Paying down the balance steadily can bring utilization back down over time.
What happens if I don't pay off the balance before the intro period ends?
Any remaining balance starts accruing interest at Chase Slate®'s standard variable APR — 18.49% - 28.49% Variable, depending on creditworthiness — instead of 0%.
Can I use a 0% APR card and a HELOC together?
Yes. Some homeowners use a card for a smaller, fixed-cost phase of a project and a HELOC for a larger or ongoing phase. Just track each balance and payoff deadline separately.
Is the intro period the same for every Chase Slate® cardholder?
The length is standard for the current offer, and it always starts at account opening. Your credit limit and ongoing variable APR depend on your creditworthiness.

A home equity line of credit (HELOC) can be the right tool for large, long-horizon renovations, and it can come with tax advantages a 0% APR credit card can't match. But for a fixed-price, moderate-size project you can realistically pay off in under two years, the default advice skips over 0% APR credit cards that can offer huge financial savings.
Our advice? Look for a 0% APR credit card like the Chase Slate® that offers a lengthy intro APR period for purchases and not just balance transfers. From there, be careful to charge only what you can afford to pay off within 21 months on Purchases (or 18 months to be on the safe side).
