Quick answer
A second-position business loan sits behind your first mortgage, leaves it untouched and can be secured by commercial, investment or residential property. A HELOC is consumer credit on a home. A cash-out refinance replaces the whole first mortgage. Axiant Partners, a business-loan broker in Boca Raton, suggests starting from one fact: is your first mortgage rate worth keeping?
Side by Side
| 2nd-position loan | HELOC | Cash-out refi | |
|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced |
| Property | Commercial, investment or home | Usually your home | Any you own |
| Rules | Business credit | Consumer credit | Depends on property |
| Sized on | Combined LTV | Combined LTV | New loan's LTV |
| Draws | Lump sum | Revolving line | Lump sum |
| Closing cost on | The new loan | The line | The whole balance |
All three are sized on equity - every loan against the property added together, divided by its appraised value - and all three put the property at risk if the business cannot pay. See second and third position lending for how combined loan-to-value works.
Is Your First Mortgage Worth Keeping?
If the first mortgage carries a rate well below today's, a cash-out refinance re-prices the whole balance to raise a fraction of it. On a $600,000 mortgage, raising $150,000 by refinancing means paying the new rate on $750,000. A second-position loan or a HELOC prices only the new money and leaves the old rate alone.
The reverse also holds: if the first mortgage is expensive, near its maturity or due for a balloon, a cash-out refinance can fix two problems at once, and one loan is simpler than two.
Business Credit or Consumer Credit
This is the difference borrowers rarely hear about. A HELOC on your home is consumer credit, so it comes with federal Truth in Lending disclosures and a three-business-day right to cancel after signing. A loan made for a business purpose is exempt from Truth in Lending, even when your home secures it - no rescission period, and fewer standard disclosures.
That cuts both ways. A business-purpose loan can close without the rescission wait, but you get fewer built-in protections, so read the terms, ask for the APR and total of payments in writing, and know exactly what default triggers. HELOC lenders also generally lend only on a home; a second-position business loan can also be secured by commercial, multifamily or rental property. (Axiant does not originate or broker home equity loans.)
Will Your First Lender Allow a Second Lien?
Read your first mortgage before applying for a second lien. On an owner-occupied home of one to four units, federal law (the Garn-St Germain Act) generally stops the first lender from calling the loan just because you add a junior lien. On commercial and investment property that protection does not apply: many commercial first mortgages prohibit additional liens or require the first lender's consent, and some contain a due-on-encumbrance clause.
A subordinate lender will not lend into a position that defaults the loan ahead of it, so this check decides many deals. More in what equity lenders require behind a first mortgage.
A Worked Comparison
Illustrative arithmetic, not a quote. A business owner needs $150,000. The property is appraised at $1,000,000 with a $500,000 first mortgage at a low fixed rate:
| 2nd-position loan | Cash-out refi | |
|---|---|---|
| New money | $150,000 | $150,000 |
| Balance at new rate | $150,000 | $650,000 |
| Old low rate kept on | $500,000 | Nothing |
| Combined LTV after | 65% | 65% |
Both end at the same combined loan-to-value. The difference is how much debt moves to today's rate. The second-position loan usually carries the higher rate of the two on its own, because it is paid after the first mortgage, but it is applied to far less money. How position affects price is covered in second and third position lending.
Which One Fits
- Low-rate first mortgage, commercial or investment property: second-position business loan.
- Your home, flexible draws over time: HELOC, if you accept putting the home behind the business; see HELOC for business.
- Expensive or maturing first mortgage: cash-out refinance.
- Equity is thin or cash flow will not carry another payment: none of them; see secured vs unsecured business loans.

Frequently Asked Questions
What is the difference between a second-position business loan and a HELOC?
Both sit behind your first mortgage. A HELOC is a consumer line of credit, usually on your home, with Truth in Lending disclosures and a right to cancel. A second-position business loan is business-purpose credit that can also be secured by commercial or investment property.
Is a cash-out refinance better than a second lien?
When the first mortgage is expensive or maturing, often yes. When it has a low rate worth keeping, a second lien usually costs less overall, because only the new money is priced at today's rate.
Can my first lender stop me from taking a second lien?
On an owner-occupied home of one to four units, federal law generally stops the lender calling the loan over a junior lien. Commercial and investment mortgages often prohibit additional liens or require consent, so read yours first.
Does a business loan secured by my home have a right of rescission?
No. Business-purpose credit is exempt from Truth in Lending, including the rescission right that applies to a consumer HELOC on your principal dwelling.
How much can I borrow in second position?
It depends on combined loan-to-value: every loan on the property divided by its appraised value, up to the lender's ceiling, and on whether the business can carry the total payments.
