The short answer
A first mortgage ranks first on a property's title and is repaid first if the property is sold, while a second mortgage ranks behind it. For business owners, a second mortgage adds funding without touching the existing bank loan, while a first mortgage replaces it or sits on a mortgage-free property. LoansOne arranges both from $20,000 to $500,000.
What does ranking on title mean?
Every property in New Zealand has a record of title held by LINZ. When a lender takes a mortgage, it’s registered on that title, and the order of registration sets the order of repayment.
- The first mortgage is at the front of the queue. If the property is sold, it gets paid out first.
- The second mortgage is next. It’s repaid from whatever is left after the first mortgage is cleared.
That’s the whole difference. Same property, same owner, different place in the queue. But that one difference changes how much a lender will lend, how it prices the loan and when each one makes sense for a business.
LoansOne arranges fast and flexible 1st and 2nd mortgages for business purposes from $20,000 to $500,000, with no cash flow or financial records needed and bad credit OK.

Why does a second mortgage usually cost more?
Risk follows ranking. If a property had to be sold, the first lender is repaid first. The second lender only gets what’s left. To balance that, second mortgage lenders usually price higher and cap combined lending at a level that keeps a buffer of equity.
But price on its own can mislead. A second mortgage often means borrowing $100,000 on top of a bank loan, while a first mortgage refinance might mean borrowing the bank’s balance plus the $100,000. If your bank loan is on a good fixed rate, keeping it and adding a smaller second mortgage can work out better overall than refinancing everything.
We never publish rates because the right comparison depends on your numbers. Pricing is set case by case, and LoansOne works to get the sharpest rate available for where you stand.
How much can you borrow on each?
Both are limited by the property’s value, but they’re calculated differently.
- First mortgage: the lender lends up to its cap on the property’s value. If you’re refinancing a bank, the bank’s balance comes out of that first, and the rest is available to the business.
- Second mortgage: the lender looks at combined borrowing. Its cap on the property’s value, minus what’s owed on the first mortgage, is the most it can lend.
Caps vary by lender, property type and location. A well-located home or commercial unit is treated more generously than a remote or unusual property. Through LoansOne, both run from $20,000 to $500,000 for business purposes.
Which is faster?
With a private lender, both are fast compared with a bank. The difference is in the detail:
- A second mortgage doesn’t touch the bank loan. Once the value and title are confirmed and the lawyers sign up, it can settle.
- A first mortgage on a mortgage-free property is just as quick: one lender, one registration.
- A first mortgage that refinances a bank also needs the bank to release its mortgage. Banks don’t always move at your pace, so start early if this is your route.
In the right circumstances, next-day funding is possible for either.
When should you use a first mortgage?
A private first mortgage is usually the better fit when:
- The property is mortgage-free. There’s no bank to sit behind, so a first mortgage is the natural structure and normally prices better than a second.
- The bank wants out. Your facility is under review or being called up, and you need to refinance quickly.
- The bank loan is small. If you only owe a little, paying it out and having one lender is simpler.
- You want one lender and one repayment. Fewer moving parts.
When should you use a second mortgage?
A second mortgage usually wins when:
- You’re happy with your bank loan. Especially on a good fixed rate you don’t want to break.
- You need extra funds quickly. No full refinance, no bank credit process.
- Your bank won’t lend more. A weak year, unfinished accounts or a credit mark has closed the door, but the equity is still there.
- The need is short to medium term. Repay it from trading, a sale or a refinance later, and the bank loan carries on regardless.
Which is right for you?
Work through these questions in order:
- Is there a mortgage on the property now? No: a first mortgage is the natural choice. Yes: go to question 2.
- Do you want to keep that bank loan? Yes: a second mortgage. No: a first mortgage that pays out the bank.
- Is the bank pushing you out or reviewing your facility? Yes: a first mortgage refinance usually makes more sense.
- Would refinancing trigger break costs on a fixed rate? Yes: lean towards a second mortgage.
- How big is the bank balance compared with what you need? A small bank balance tilts towards a first mortgage; a large one towards a second.

A worked example
Here’s an illustrative scenario showing how the two options compare on the same property. It uses property values only, never rates.
A Palmerston North engineering firm owns its workshop, valued at $800,000. The bank is owed $250,000 on a fixed rate with a year to run. The owner needs $150,000 for new machinery and working capital, and the accounts for last year aren’t finished.
| Option A: second mortgage | Option B: private first mortgage | |
|---|---|---|
| New borrowing | $150,000 | $400,000 (pays out the bank plus $150,000) |
| Bank loan | Stays at $250,000, fixed rate kept | Paid out |
| Break costs | None | Possible on the fixed rate |
| Lenders | Two | One |
| Financial records | Not needed | Not needed |
Option A keeps the bank’s fixed rate and borrows only the new money. Option B creates one clean loan but refinances the bank balance at private pricing. For this owner, the second mortgage is likely the better fit. If the bank were calling up the loan, Option B would win. That judgement is exactly what LoansOne’s experts make on every application.

Can a second mortgage be refinanced later?
Yes, and it’s a common plan. Many owners take a second mortgage to solve an immediate problem, then tidy things up once the dust settles. Typical routes:
- Repay it from trading over the term.
- Roll both mortgages into one bank loan once the accounts are done and the bank is comfortable again.
- Refinance both into a private first mortgage if the bank loan is coming up for renewal anyway.
- Clear it from a sale of a property, asset or the business.
Whichever route you plan, mention it when you apply. A clear exit strengthens the application and helps the expert match you to a lender with a term that fits.
What about a caveat or an unsecured loan?
Two other options sometimes beat both:
- A caveat loan can be quicker still for a very short, sharp need, though it isn’t a registered mortgage. See caveat loan vs second mortgage.
- An unsecured business loan keeps property out of it entirely if your trading is strong. See unsecured business loan vs second mortgage.
