Using a HELOC to Buy a Franchise: Risks and Tax Rules

A HELOC is one of the more tempting ways to fund a franchise, because home equity is often the largest pool of money a would-be owner can reach, and a secured line can carry a lower rate than unsecured debt. It is also one of the riskiest, for a single reason: it puts your house on the line for a business that might not work. The tradeoff, more than the rate, is what to understand before you draw a dollar.

This guide explains how a HELOC works for a franchise purchase, states the foreclosure risk plainly, corrects the tax assumption buyers most often get wrong, and compares it to the other financing routes. Nothing here is a promise of approval, a rate, or a recommendation to use one; those are decisions for you, a lender, a CPA, and a financial advisor. For the broader picture, start with how much money it takes to start a franchise.

What is a HELOC, and how is it used for a franchise?

A home equity line of credit is, in the CFPB’s words, an open-end line of credit that lets you borrow repeatedly against your home equity. It works in two phases: a draw period, commonly around ten years, when you can borrow up to your limit as needed, followed by a repayment period, often ten to twenty years, when new borrowing stops and payments typically rise. The rate is usually variable, so what you owe each month can change.

Franchise buyers use HELOC funds three main ways: as the cash equity injection an SBA lender requires, as working capital to carry the business through its early months, or as the full initial investment for a smaller concept. The International Franchise Association has noted that franchisees do turn to home equity for financing, precisely because it can be cheaper than unsecured borrowing. The appeal is real. So is the catch, which is the whole point of the next section.

The risk that matters most: your home

A HELOC is secured by your house, which means the lender’s remedy if you cannot pay is your home. The CFPB puts it directly: if you fall behind or cannot repay, “you could lose your home.” A franchise is a business that can fail for reasons outside your control, a bad location, a downturn, a brand stumble, and a HELOC ties that business risk to the roof over your family.

There is a second, less-discussed risk. The CFPB notes that a lender can freeze or reduce your credit line if your home’s value falls significantly or if it believes your financial situation has changed. That can cut off access to funds you were counting on in the middle of a build-out or a launch, when you can least afford the surprise. Between the foreclosure exposure and the freeze risk, a HELOC is not a source of money to lean on lightly, and it is the reason many advisors steer new owners toward financing secured by the business rather than the home.

The tax rule buyers get wrong

Here is the assumption that trips people up: that because a HELOC is a home loan, the interest is tax-deductible like mortgage interest. For a franchise purchase, it generally is not. Under IRS Publication 936, interest on a loan secured by your home is deductible as home-mortgage interest only to the extent the funds are used to buy, build, or substantially improve the home that secures the loan. Money you pull out to fund a business does not meet that test, so the mortgage-interest deduction generally does not apply.

That interest may instead be deductible as a business expense, depending on how the funds are used and how your business is structured, but that is a judgment for a CPA, not a blanket rule to assume. And this is not a temporary quirk waiting to expire: 2025 tax legislation removed the prior sunset date for this rule, so it is standing law rather than a provision set to lapse. Tax law can still change through future legislation, though, so confirm the current treatment with a CPA. The practical takeaway is simple: do not count on a tax deduction to make the HELOC math work until a tax professional confirms how it applies to your specific situation.

HELOC versus SBA, ROBS, and unsecured loans

Every financing route puts the risk somewhere. The table lays out where, without endorsing any of them.

Option	Secured by	The main tradeoff
HELOC	Your home	Possibly a lower rate, but default can mean foreclosure
SBA 7(a)	Mostly business assets, plus a guaranty	Franchise-focused and up to $5M, but needs an equity injection and is generally slower
ROBS	Your retirement account	No loan and no credit check, but it spends retirement savings the IRS found often get lost to business failure
Unsecured business loan	Nothing pledged	No home or retirement at risk, but usually higher cost and smaller amounts

A few notes. An SBA 7(a) loan is the most common franchise financing vehicle, usable for franchise fees, equipment, and working capital up to $5 million, and it is secured largely by the business, though it requires a cash equity injection and the brand must clear the SBA Franchise Directory. A ROBS avoids credit checks by using your own retirement funds, but the IRS’s ROBS compliance project found high rates of failure and bankruptcy among businesses funded that way, so the risk is your retirement rather than your home. A HELOC can undercut an unsecured loan on rate because it is secured, but again, the security is your house. Which risk you can live with is the real question, and it is one for a financial advisor.

Questions to ask your lender and CPA

Before you sign, put these to your lender directly, and treat vague answers as a red flag.

• What are the current rate, the index it is tied to, the draw and repayment terms, and how high could my payment go if rates rise?
• Under what conditions could you freeze or reduce my line, and what would that do to funds I am relying on for the build-out?
• Ask a CPA whether the interest on funds used for this franchise is deductible for me, as a business expense or otherwise, given my structure.
• If the business cannot repay, exactly what is the process, and what happens to my home?
• Ask a financial advisor to compare a HELOC against an SBA 7(a) loan and, if relevant, a ROBS, on total cost and on which asset each one puts at risk. You can pressure-test whether the projected cash flow can service the payment with our franchise loan payment calculator.
