Most small business owners I talk to have never seriously considered the equity in their home as a funding source. They think of HELOCs as something you use to remodel a kitchen. I’ll be honest: I used to think the same thing, until I watched a client of mine use a $120,000 HELOC to fund her first year of inventory and working capital for a retail business that’s now doing over $800K annually. That reframed the whole question for me.

So I went deep on this. I talked to lenders, reviewed the SBA’s own guidance on alternative funding structures, and looked hard at where HELOCs make sense for business owners and where they’re genuinely dangerous. Here’s what I found.

What You’re Actually Doing When You Use a HELOC for Business

A HELOC (home equity line of credit) lets you borrow against the equity you’ve built in your home, typically up to 80-85% of your home’s appraised value minus what you still owe on the mortgage. Most lenders give you a draw period of 10 years where you pull money as needed and pay interest only, followed by a repayment period of 10-20 years.

When you use that line for business purposes, you’re doing something that’s conceptually simple but operationally messy: you’re pledging a personal asset to fund a business risk. The money is cheap, flexible, and fast to access. The collateral is your house.

That’s not a reason to avoid it. It’s a reason to think carefully.

What surprised me was how often this structure actually makes more sense than a traditional business loan, especially for early-stage companies. A brand-new LLC with no revenue history can’t get an SBA 7(a) loan. It usually can’t get a business line of credit either. But if the owner has $200,000 in home equity and a solid personal credit score, a HELOC is accessible in a way that most business financing simply isn’t.

HELOCs are tied to the prime rate, which means the interest rate floats. In a rising rate environment that’s a real risk. In a stable or declining one, you’re often looking at rates that beat personal loans, credit cards, and many small business loans by a significant margin. As of mid-2026, HELOC rates at major lenders are generally running in the 7-9% range for well-qualified borrowers, which compares favorably against business lines of credit at 10-14% or merchant cash advances that can carry effective APRs well above 30%.

No, I’m not saying a HELOC is always cheaper. Points, appraisal fees, and annual fees add up. But on a dollar-for-dollar basis, for a borrower with good credit and meaningful equity, it’s hard to beat on cost.

The Tax Situation Is Genuinely Complicated

I’m going to be honest here: consult a CPA before you do anything. I mean that.

The 2017 Tax Cuts and Jobs Act changed the deductibility rules for home equity interest, and the current guidance is that interest on a HELOC is only deductible if the proceeds are used to “buy, build, or substantially improve” the home securing the loan. Business use doesn’t qualify for that deduction under the personal mortgage interest rules. However, if you’re using HELOC funds for business purposes, you may be able to deduct the interest as a business expense, because the IRS looks at how the money is actually used, not just the loan instrument.

The research here is genuinely mixed on how cleanly this works in practice, and the documentation requirements are real. Keep your draw records, keep your business bank account separate, and get a CPA involved before you file. Don’t assume either way.

When a HELOC Makes Sense for Business Funding

Here’s where I’ll take a stance, because I think a lot of the generic advice on this topic is either too enthusiastic or too scared.

A HELOC works well for business funding when you have a clear, short-to-medium-term need, a realistic repayment plan, and some cushion if things go sideways. Working capital gaps, initial inventory, a piece of equipment, or bridge funding while you wait on a larger business loan to close. These are good use cases. The draw-as-needed structure means you only pay interest on what you’ve actually pulled, which is a real advantage for uneven cash flow.

It gets risky when you’re using it to fund a business that has no defined path to profitability. Or when the HELOC represents most of your accessible capital, so there’s no margin for error. I’ve seen owners tap $150,000 in home equity into a concept that failed in 18 months. They lost the equity and still owed the loan. That’s not a hypothetical.

The Consumer Financial Protection Bureau’s small business resources are worth reading before you commit, particularly around understanding adjustable rate products and what happens during the repayment phase if business income drops.

A book I’ve recommended to several clients is Profit First by Mike Michalowicz (affiliate link, the site may earn a small commission). Not because it’s specifically about HELOC funding, but because the cash management discipline it builds is exactly what you need if you’re using a personal credit line to run a business. If you don’t have that discipline before you open the line, you’re going to use it like an ATM.

Keeping the Books Straight

One thing people underestimate: the accounting gets messy fast. HELOC draws are coming from your personal bank account (or directly to your personal account), and you’re spending them on business expenses. If you’re not meticulous about tracking this, you’ll create a bookkeeping nightmare and potentially blow up your liability protection if you’re operating as an LLC.

The cleanest approach is to open a dedicated personal account for HELOC draws, transfer what you need to your business account, and document each transfer as either a loan to the business or an owner contribution. Which structure you use matters for taxes, so again, CPA conversation first.
