The short answer
A caveat loan is secured by a caveat lodged on your title, a notice of the lender's claimed interest, while a second mortgage is a registered mortgage ranking behind your first. Caveat loans are usually quicker and suit very short, smaller needs. Second mortgages give the lender stronger security, so they usually suit larger amounts, longer terms and sharper pricing.
Caveat loan or second mortgage: what’s the real difference?
If you own property and need business funding quickly, two options come up again and again: a caveat loan and a second mortgage. They sound similar and they solve similar problems. Both leave your bank’s first mortgage in place, both use your equity, and both can be arranged by private lenders far faster than a bank.
The difference is in how the lender’s security is recorded on your title, and that one detail ripples through speed, cost, loan size, term and risk.
- A second mortgage is a mortgage registered on your record of title through LINZ. It ranks behind your first mortgage and gives the lender a registered security.
- A caveat loan is backed by a caveat, a notice lodged on your title through LINZ that the lender claims an interest in the property. It blocks dealings that affect that interest, but it is not a registered mortgage.
If you want the mechanics of each in detail, see our pages on caveat loans and second mortgages. This page is about choosing between them.
How do caveat loans and second mortgages compare side by side?
| Caveat loan | Second mortgage | |
|---|---|---|
| How it’s recorded | Caveat lodged on the title with LINZ | Mortgage registered on the title with LINZ |
| Lender’s position | Claimed interest; blocks affected dealings | Registered security ranking behind the first mortgage |
| Documentation | Lighter | Fuller mortgage documents |
| Speed | Usually the quickest property-backed option | Fast with a private lender, a few more steps |
| Typical term | Weeks to a few months | A few months to longer terms |
| Typical size | Smaller, conservative against equity | Larger amounts within your equity |
| Pricing | Reflects lighter security, rarely cheapest | Usually sharper for the same situation |
| Effect on selling | Loan repaid from settlement, caveat withdrawn | Loan repaid from settlement, mortgage discharged |
| Financial records | Property and exit focused | No cash flow or financial records needed through LoansOne |
| Bad credit | Often considered | OK |

Registration: why does it matter how the security is recorded?
This is the heart of the comparison, so it’s worth a closer look.
A registered second mortgage is a formal security interest on the title. The order of registration sets priority, so the first mortgage is repaid first and the second next. Because the lender’s position is clear and recorded, it can lend more confidently, for longer, and price accordingly.
A caveat works differently. It’s a warning on the title that stops LINZ registering any dealing that affects the lender’s claimed interest, like a sale transfer or a new mortgage, without the lender’s consent or the caveat coming off. That gives the lender real leverage, which is why caveat lending works, but it’s a weaker position than a registered mortgage. Caveats can also be challenged through a lapse process under the Land Transfer Act 2017, although in a normal loan that never comes into play.
The practical result: caveat lenders keep loans short and conservative, and second mortgage lenders can offer more room.
Speed: how much faster is a caveat loan?
Usually a little faster, not dramatically faster. A caveat loan skips the full mortgage documentation, so if every hour counts it can have the edge.
But the biggest factors in speed are the same for both:
- A complete application with property and ownership details ready
- A lawyer lined up to advise you and sign documents
- A clear exit the lender can see straight away
- The right lender first time, rather than a round of declines
With those in place, next-day funding is possible for both, and many LoansOne loans are paid out within 24 hours. If you have a few days to spare, the small speed advantage of a caveat often isn’t worth giving up the better structure of a second mortgage.
Cost: which one costs more?
We don’t publish rates, because every loan is priced on the client’s individual circumstances, and LoansOne works to get the sharpest rate available for your situation. But the general pattern is clear.
Caveat loans carry more risk for the lender because the security is lighter. That usually shows up in the price, and in a shorter term.
Second mortgages give the lender a registered security, so for the same property, equity and borrower, they’re usually priced more keenly.
The things that move the price for both:
- How much equity sits behind the loan after the first mortgage
- Loan size and term
- How clear and certain the exit is
- Property type and location
- How interest is paid, monthly or at the end
Always compare total cost, not just the headline rate. Our compare loan offers tool puts two quotes side by side.
Risk: what should a borrower watch for?
Both options put your property on the line, so treat both with respect.
With a caveat loan:
- The term is short, so a delayed sale or refinance can leave you scrambling
- Extension costs can add up if the exit slips
- Repeated caveat loans to cover ongoing shortfalls are a warning sign, not a strategy
With a second mortgage:
- You’re committing to a registered security, which needs to be discharged when you sell or refinance
- Two mortgages mean two lenders to deal with if your plans change
- Your first mortgage terms may need to be checked, which your lawyer will handle
For both, the protection is the same: borrow what you need, have a realistic exit and build in a buffer. The equity calculator shows how much room your property gives you before you commit.
When does a caveat loan win?
- You need funds within days, not a week
- The amount is small relative to your equity
- The term is weeks or a few months
- The exit is close and certain, such as an unconditional sale
Illustrative example: A Dunedin builder has sold a completed townhouse unconditionally, settling in six weeks. A supplier offers a large discount on materials for the next job if paid this week. A short caveat loan over the builder’s own home pays the supplier and is repaid when settlement lands.
When does a second mortgage win?
- The amount is larger
- The term is several months or more
- You want the sharper pricing a registered security usually brings
- The exit is solid but not immediate, such as trading income over time or a refinance next year
Illustrative example: A Tauranga marine services business needs $180,000 to clear IRD arrears and buy a second work vessel. The owners have strong equity in their home behind a bank mortgage. A second mortgage over a longer term gives them breathing room, keeps the bank’s loan untouched and is repaid from trading and a later refinance.

Is there an option that doesn’t use your property at all?
Yes. If your business trades steadily and you’d rather keep your property out of it, an unsecured business loan from $20,000 to $500,000 is worth a look. It’s assessed mainly on your business bank statements, and no real estate security is required in most cases. Our unsecured loan vs second mortgage comparison explains when that trade-off makes sense.
Property-secured options tend to win when your records are behind, your credit history has marks on it, or you need a larger amount than your trading alone would support.
What questions should you ask before choosing?
Whichever way you lean, put these questions to any lender before you sign:
- What is the total amount I’ll repay, including all fees?
- How is interest charged: monthly, or added and paid at the end?
- What happens if my exit is delayed by a few weeks?
- Can I repay early, and is there a cost to do so?
- How will the security be removed from my title once I’ve repaid?
Clear answers to these tell you more about a loan than the headline rate ever will.
How does LoansOne help you choose?
You don’t have to pick the security type yourself. When you apply, an expert reviews your situation, the property and your exit, then matches you to the lender and structure that fit. We’re not tied to one product, so the recommendation follows your circumstances.
- No credit file mark when you enquire
- Not shopped around to dozens of lenders
- Secured and unsecured options from $20,000 to $500,000
- Bad credit considered, and no financial records needed for property-secured lending
