If you own your home, your business property, or both, you may be sitting on capital you have never used. The harder question is not whether you can borrow against it. It is which property you should put on the line, and whether you should at all.
This guide walks through that decision honestly. You will see what each option typically allows, what it costs, what is actually at risk, and the cases where the answer should be “neither.”
Why this question matters more in 2026
American homeowners have never had more equity. ICE’s August 2026 Mortgage Monitor puts mortgage holder equity at a record $18 trillion, with 47.5 million mortgage holders sitting on $11.7 trillion of tappable equity, about $212,000 each on average (ICE).
Small business owners are already reaching into personal resources. In the Federal Reserve’s Small Business Credit Survey, 58% of employer firms with 1 to 4 employees that faced a financial challenge used the owner’s personal funds to deal with it (FRED / Fed Small Business).
So the money is there, and owners are using it. The risk is doing it by default instead of by design.
Two paths: a residential HELOC vs. a commercial equity line
Both are revolving lines of credit secured by real estate. You draw what you need, repay, and draw again. The differences are in how much you can access, how they are priced, and what you stand to lose.
| Borrowing against your home | Borrowing against your commercial property | |
|---|---|---|
| Typical maximum combined loan-to-value (CLTV) | 80%–85% of appraised value | 65%–75% of appraised value |
| How the rate is usually set | Variable: prime rate plus a lender margin | Variable: benchmark rate plus a lender margin |
| Current market benchmark | National average HELOC rate 6.78% (Sept 24, 2026) | No published national average; quoted case by case |
| What lenders weigh most | Your personal credit, income and home equity | The property, its income and your business financials |
| What is at risk if you can’t repay | Your family’s home | A business asset, often your operating location |
Sources: CLTV ranges from The Mortgage Reports and Clarify Capital; rate from MonitorBankRates. Actual terms vary by lender, state, property and borrower.
How much could each property unlock? A worked example
Illustrative Composite Scenario. The following example combines typical figures for teaching purposes. It does not describe a real client, and it is not an offer or approval.
Maria owns a catering company. Her home is worth $600,000 with $300,000 left on the mortgage. She also owns the commercial kitchen her company operates from, worth $900,000 with a $400,000 mortgage.
The formula lenders use is the same for both: property value × maximum CLTV − existing mortgage balance.
| Property | Value | Mortgage | CLTV used | Estimated maximum line |
|---|---|---|---|---|
| Home | $600,000 | $300,000 | 85% | $210,000 |
| Commercial kitchen | $900,000 | $400,000 | 75% | $275,000 |
| Commercial kitchen (conservative lender) | $900,000 | $400,000 | 65% | $185,000 |
On paper, the building unlocks more at a generous lender and less at a conservative one. But the dollar figure is the least important line in that table.
What you’re really putting on the line
The Consumer Financial Protection Bureau’s HELOC booklet says it plainly: a HELOC uses your home as collateral, and if you can’t repay, you could lose your home (CFPB booklet).
Forming an LLC does not change that. If the line is secured by your house, your house is the collateral, whatever entity spends the money.
Borrowing against a commercial building puts a business asset at risk instead. That is not risk-free either. If the building is where you operate, losing it can end the business. But it keeps the outcome inside the business rather than at your kitchen table.
Ask yourself this before you look at any rate: if the next 18 months go badly, which loss could your family survive?
When borrowing against your home can make sense
- You have a clear, short-term use with a predictable payback, such as a seasonal inventory build you have run successfully before.
- Your household could cover the payments from personal income if business revenue dipped.
- You don’t own commercial property, or your building is already heavily financed.
- Your business is too new for traditional business credit, and you understand the trade-off you are making.
When the commercial property is usually the better path
- You own the building outright or with a modest mortgage, so the equity is substantial.
- The money is for the business that occupies or earns income from the property.
- You want business debt to stay a business decision, separate from the family home.
- You have a spouse or co-owner on the home title who isn’t involved in the business.
When the honest answer is “neither”
- The need is urgent. Real estate lines require appraisals and title work, which usually takes weeks. If payroll is due Friday, equity won’t arrive in time. That is where short-term working capital such as a merchant cash advance is built to fit. We compare the two side by side in HELOC or Cash Advance? Run the Real Numbers.
- You’re covering ongoing losses. Equity used to plug a recurring shortfall delays the problem and raises the stakes.
- Your equity is thin. If you’d be borrowing up to the lender’s cap, a small dip in values can leave you with no cushion. ICE counted 813,000 underwater mortgage holders in its August 2026 report, up 44% from a year earlier (Inman).
- You’d be pricing in falling rates. Most of these lines are variable. The Federal Reserve raised its target range on September 16, 2026, so plan for rates that can rise. Our rate guide, Rates Are Moving, shows what that does to a payment.
Five questions to settle at the kitchen table first
- What exactly will this money do, and how does it pay itself back?
- If business revenue fell 30% for six months, how would you make the payments?
- Who else is on the title, and have they agreed to this?
- Is the rate variable, and what is the lifetime cap?
- Have you talked to your CPA? Using home equity for business purposes can change how the interest is treated for tax purposes.
Other options worth comparing
Real estate isn’t the only collateral. If you’re buying machinery or vehicles, equipment financing secures the funding with the equipment itself. If you want revolving access without pledging property, compare a business line of credit.
