Using a HELOC to Start a Business: What You Need to Know Before You Borrow

Homeowners across the country are sitting on a combined $11.5 trillion in home equity, and a growing number of entrepreneurs are eyeing that equity as a way to fund a new venture. It is easy to see the appeal. A Home Equity Line of Credit, or HELOC, often carries a lower interest rate than a business loan, and the application can move faster than a trip through the Small Business Administration’s approval process.

But borrowing against your home to fund a business is a fundamentally different risk than borrowing against future business revenue. If the venture struggles, a business loan default hurts your business credit. A HELOC default puts your house on the line. This guide walks through how a HELOC works for business funding, what it actually costs in 2026, the tax rules the IRS applies, and how it compares to SBA loans and business lines of credit so you can decide whether this is the right move before you sign anything.

Why Entrepreneurs Consider a HELOC for Business Funding

The math is the first draw. As of mid-2026, the prime rate sits at 7.50%, and HELOC rates typically price at prime plus a margin of 0.50 to 2 percentage points, putting most well-qualified borrowers in the 7.25% to 8.75% range according to Bankrate and PrimeRates data. Compare that with an SBA 7(a) loan, which NerdWallet reports currently runs 9.75% to 14.75% APR, or a standard business line of credit, which commonly lands between 8% and 25% APR depending on the lender and the borrower’s credit profile.

Speed is the second draw. A HELOC that is already open, or one opened against a primary residence with clean title and strong equity, can close in two to four weeks. An SBA loan routinely takes six to twelve weeks from application to funding because of the underwriting layers involved in a government-guaranteed program.

Access is the third draw. Newer businesses without two years of tax returns or established revenue often cannot qualify for a bank term loan or the best SBA rates. A HELOC is underwritten against the homeowner’s equity, credit, and personal income, not the business’s track record, which opens the door for pre-revenue founders and first-year businesses that traditional business lenders would turn away.

The Trade-Off: Your Home Is the Collateral

A HELOC is a second lien secured directly by your house. A business loan, even one backed by a personal guarantee, generally has to work through a legal collection process before it can touch your home. A HELOC skips that step entirely. If the business fails and the HELOC balance goes unpaid, the lender can move toward foreclosure on your primary residence, the same as if you had missed mortgage payments.

This is the single biggest difference between using a HELOC and using almost any other form of business capital, and it should shape how much of the line you are willing to draw and how conservatively you plan repayment. Financial advisors generally recommend keeping the amount you draw for a business well below your full approved limit and building a repayment plan that does not assume best-case revenue from day one.

Tax Deductibility: What the IRS Actually Allows

This is where many borrowers get tripped up. Since the Tax Cuts and Jobs Act, HELOC interest is only deductible as home mortgage interest when the funds are used to buy, build, or substantially improve the home securing the loan. Using a HELOC to fund a business does not meet that test, so the interest is not deductible as home mortgage interest on Schedule A.

That does not necessarily mean the interest is lost as a deduction. If the funds are used for an active trade or business, the interest may be deductible as a business expense on Schedule C, or on the applicable business return, under the ordinary rules for business interest expense. This distinction, deductible as business interest rather than home mortgage interest, matters for your recordkeeping. The IRS expects you to be able to trace exactly how the borrowed funds were used, which means keeping the HELOC draw separate from personal spending and documenting every dollar that goes into the business.

Because business interest deduction rules include limitations tied to a business’s adjusted taxable income, and because a sole proprietor’s situation looks different from an LLC or S-corp structure, this is a conversation to have with a CPA before you draw funds, not after you file.

HELOC vs. SBA Loan vs. Business Line of Credit: Side-by-Side

No single option wins on every dimension. The table below lines up the three most common paths small business owners consider in 2026.

A Worked Example: $60,000 for a Startup

Consider a homeowner with $60,000 in available HELOC capacity at 8.00% APR, drawn in full to launch a business. During a typical 10-year interest-only draw period, the monthly payment on the full balance would run approximately $400. The same $60,000 financed through an SBA 7(a) loan at 11% APR amortized over 10 years would carry a fully amortizing payment closer to $827 a month, since principal repayment starts immediately.

The HELOC looks cheaper on a monthly basis, but the comparison is incomplete. The full $60,000 principal is still outstanding when the draw period ends, at which point the loan converts to a fully amortizing schedule, often at a higher required payment than the SBA loan carried the whole time. A variable rate also means that $400 figure can rise if the prime rate climbs before the business is generating steady revenue.

Before You Draw: A Pre-Borrowing Checklist

• Confirm your combined loan-to-value ratio leaves at least 15 to 20 percent equity cushion after the draw, which most lenders require and which protects you if home values soften.
• Separate the HELOC funds into a dedicated business account immediately, so you can document business use for tax purposes and avoid commingling with personal spending.
• Build a repayment plan based on a conservative revenue scenario, not your best-case business projection, since HELOC payments still come due even if the business is slow to gain traction.
• Ask your lender directly what happens to your HELOC rate and payment if you later draw against the same line for a home improvement or personal need, since some lenders restrict mixed-use lines.
• Talk to a CPA about how to document the loan proceeds so any deductible business interest is defensible if the IRS ever asks.
• Get a second opinion on whether an SBA microloan, business line of credit, or even a co-signed loan might fund the same need without your home as collateral.

Who Should Think Twice

A HELOC for business funding tends to work best for an established homeowner with a stable, separate source of income to cover the HELOC payment even if the business generates zero revenue in its first year. It tends to work poorly for a founder who is depending entirely on the new business to cover both living expenses and the HELOC payment, since that scenario has no cushion if the launch takes longer than planned.

If your business plan requires a large lump sum with a long, predictable schedule, an SBA loan may ultimately cost less over the funding’s life despite its higher headline rate, since the structure is fixed rather than exposed to a multi-year variable rate.

Frequently Asked Questions

Can I use a HELOC to start a business?

Yes. Most HELOC lenders do not restrict how you use the funds once the line is open, so business use is generally permitted. The lender is underwriting your home equity, credit, and income, not your business plan, which is different from a traditional business loan.

Is HELOC interest used for a business tax-deductible?

Not as home mortgage interest, since the Tax Cuts and Jobs Act limits that deduction to funds used to buy, build, or substantially improve the home. The interest may qualify as a deductible business expense instead, subject to business interest expense rules, so talk to a CPA and keep clear documentation of how the funds were used.

What happens if my business fails and I cannot repay the HELOC?

Because a HELOC is secured by your home, the lender can pursue foreclosure on your primary residence if the balance goes unpaid, the same as with a missed mortgage payment. This is a materially higher personal risk than defaulting on an unsecured business loan or line of credit.

How much can I typically borrow with a HELOC for a business?

Your limit depends on your combined loan-to-value ratio, which most lenders cap between 80 and 85 percent of your home’s value, including your existing mortgage balance. A $400,000 home with a $250,000 mortgage balance at an 85 percent CLTV cap could support a HELOC of roughly $90,000, though your credit score and income further shape the final offer.

Is a HELOC cheaper than an SBA loan for business funding?

Often yes on rate. HELOC rates in 2026 typically run 7.25% to 8.75%, compared with 9.75% to 14.75% for SBA 7(a) loans. But the HELOC’s interest-only draw period means principal is not being paid down, so the total cost comparison depends heavily on how quickly you repay principal once the draw period ends.

Do I need good credit to use a HELOC for a business?

Yes. Most HELOC lenders look for a credit score of 680 or higher, and the best rates typically go to borrowers above 740. Because the HELOC is underwritten on your personal profile rather than the business, your personal credit history carries more weight than it would for many small business loan products.

Can a brand-new business with no revenue get a HELOC?

Yes, because HELOC approval is based on your home equity, personal income, and credit rather than the business’s financial history. This is one of the main reasons pre-revenue founders consider a HELOC when they would not yet qualify for a bank term loan or the strongest SBA rates.

What is the difference between a HELOC and a home equity loan for business funding?

A HELOC is a revolving line you draw from as needed and repay, with a variable rate. A home equity loan delivers a single lump sum at closing with a fixed rate and a set repayment schedule. A lump sum from a home equity loan may fit a one-time startup cost better, while a HELOC’s revolving structure suits ongoing or uncertain funding needs.

How long does it take to get a HELOC to fund a business?

A typical HELOC closes in two to four weeks from application, assuming a straightforward appraisal and clean title. That is meaningfully faster than the six to twelve weeks that SBA-backed loans commonly take to fund.
