First vs second mortgage business loan: which suits you?

When you borrow against property for your business, one of the first decisions is whether the loan should be a first mortgage or a second mortgage. Both can unlock equity quickly. Both can be used for almost any genuine business purpose. But they suit different situations, and choosing the wrong one can cost you time, money or flexibility. This guide compares a first vs second mortgage business loan side by side, with practical questions and New Zealand examples to help you decide.

In short: if the property is mortgage-free, or your existing lender needs replacing, a first mortgage is usually the natural fit. If you have a good bank loan you'd rather keep, a second mortgage usually is. The detail is where it gets interesting.

What's the difference between a first and second mortgage business loan?

The difference is priority: the order in which lenders are repaid if the property is sold. A first mortgage ranks at the front of the queue. A second mortgage ranks behind an existing first mortgage.

• A first mortgage business loan is secured as the leading mortgage on the record of title. It's used when the property has no mortgage, or when the new loan repays the existing lender so the new lender takes first place.
• A second mortgage business loan is secured behind an existing first mortgage, usually a bank home loan. The bank's loan stays in place and the new lender registers second.

Priority matters because it shapes the lender's position. A first mortgage lender is repaid before anyone else. A second mortgage lender is repaid only after the first mortgage is cleared. That affects how lenders assess, structure and price each type.

First vs second mortgage: how do they compare?

Here's a side-by-side comparison on the points that matter most when you're deciding.

Factor	First mortgage business loan	Second mortgage business loan
Position on title	Leading mortgage	Behind the existing first mortgage
Existing bank loan	Repaid and replaced, or there isn't one	Stays in place, unchanged
Loan amount needs to cover	Any existing debt plus your new need	Only your new need
Fixed-rate break costs	May apply if a fixed bank loan is repaid early	Usually avoided because the bank loan stays
Bank involvement	Bank is repaid at settlement	Bank may need to be notified or consent, depending on its terms
Number of loans	One	Two
Typical speed	Fast; involves repaying the existing lender	Often fastest, as nothing needs refinancing
Common uses	Mortgage-free property; replacing a bank loan in arrears; consolidating debts	Topping up for tax, stock, a contract or equipment while keeping a good bank loan

With fundU, both types are available from $20,000 to $1m, secured on New Zealand residential, commercial or industrial property, and some land or lifestyle property case by case.

When does a first mortgage business loan make sense?

A first mortgage is usually the better fit when the property is free of debt or when your current lender is part of the problem. Consider it when:

• The property is mortgage-free. There's nothing to sit behind, so the loan naturally takes first place.
• The existing mortgage is small. Refinancing a modest balance into one loan can be simpler than managing two.
• Your bank loan is in arrears or under pressure. If your bank is asking questions, replacing it can give you breathing room and one relationship to manage.
• Your bank won't agree to a second mortgage. Where the bank's consent isn't forthcoming, refinancing it out removes the obstacle.
• You want to consolidate. A first mortgage can repay the bank plus expensive short-term debts in one go. Our guide on refinancing expensive short-term business debt covers this.

When does a second mortgage make more sense?

A second mortgage is usually the better fit when your bank loan is working well and you only need to add funding on top. Consider it when:

• Your bank loan is on a good fixed rate. Keeping it avoids break costs and preserves the rate for the rest of the fixed term.
• Your existing mortgage is large. Refinancing it all would push the loan size up, possibly beyond what you need or what fits the $1m ceiling.
• The need is short-term. A tax bill, a stock purchase or a contract gap doesn't justify moving your whole mortgage.
• Speed is critical. Nothing needs to be refinanced, so it's often the quickest route.
• You want to keep your bank relationship. Many owners plan to refinance back to their bank later, and keeping the bank loan in place makes that easier.

Our guide on how a second mortgage works for business explains the mechanics step by step.

How do fixed-rate break costs affect the choice?

If your bank loan is on a fixed rate and you repay it early, your bank may charge a break cost. That cost can tip the balance towards a second mortgage.

Break costs vary with the size of the loan, the time left on the fixed term and how interest rates have moved since you fixed. Only your bank can tell you the figure, so ask for a written quote before you decide. If the break cost is significant, a second mortgage lets you leave the fixed loan untouched until it rolls off. If the loan is floating, or the fixed term ends soon, a first mortgage refinance becomes easier to justify.

Ask your bank for a break cost quote and your exact payout figure at the same time. Having both in writing makes the first vs second decision much clearer, and saves a round of questions later.

How does the choice affect how much you can borrow?

With a first mortgage refinance, the loan has to cover your existing mortgage as well as your new need. With a second mortgage, it only needs to cover the new need. That difference matters more than many owners expect.

Here's a simple example. Say your property is worth $1.5m, your bank mortgage is $700,000, and your business needs $300,000.

• As a first mortgage, the loan would need to be about $1m: $700,000 to repay the bank plus $300,000 for the business. That's at the top of fundU's lending range, and it means refinancing debt that was working fine.
• As a second mortgage, the loan would be $300,000, sitting behind the bank's $700,000.

In both cases the total lending against the property is the same. What changes is the size of the new loan, the cost of moving the existing loan and what you'll need to refinance at the end. Our guide on how much you can borrow against your property explains how lenders look at equity.

A quick checklist to help you decide

Work through these questions with your accountant or lawyer, and bring the answers to your first conversation with a lender.

1. Is there a mortgage on the property now? If not, it's a first mortgage.
2. How much is owing, and is the loan fixed or floating?
3. What would your bank charge to break the fixed term early?
4. Does your bank loan allow a second mortgage behind it, or will the bank need to agree?
5. How much do you need for the business, and for how long?
6. Would refinancing the bank take the loan above what you actually need?
7. Is your bank loan up to date, or is the bank pressing you?
8. What's your exit, and is it easier with one loan or two?

Example scenario: first mortgage

A Dunedin retailer owned the building their shop trades from, with no mortgage. They needed about $300,000 to fund a second store and extra stock ahead of the busy season, and their bank wanted a long list of documents and several weeks to decide.

A first mortgage of $300,000 over the building, valued at around $1.1m, funded the fit-out and stock. Interest was capitalised for the first six months while the new store got established, then moved to interest-only. The exit was a refinance to a bank once the second store had a year of trading. This is an illustrative example only.

Example scenario: second mortgage

A Queenstown tourism operator needed $150,000 to replace two vehicles and cover wages before the winter season. Their home loan was fixed for another 18 months, and breaking it would have been expensive. A second mortgage of $150,000 behind the bank loan kept the fixed rate untouched, and was repaid from winter trading. This is an illustrative example only.

What paperwork does each type need?

Much of it is the same. For either type, fundU's initial assessment focuses on the property, the purpose and the exit, and we don't need financial statements or tax returns to take a first look. The differences show up around the existing mortgage.

For both types, have these ready:

• the property address, a rough idea of its value and who owns it
• photo ID for each borrower, director, trustee and guarantor
• a short explanation of what the funds are for and how you'll repay them
• recent business bank statements, or other evidence such as contracts, invoices or an accountant's letter

For a first mortgage refinance, you'll also need a payout figure from your current lender and details of any fixed-rate break cost. Your lawyer arranges for the existing mortgage to be repaid and discharged at settlement.

For a second mortgage, you'll need a recent statement for your existing bank loan showing the balance and that it's up to date. Your lawyer checks whether the bank needs to be notified or to consent, and handles that as part of the documents.

What happens at the end of each type of loan?

Both types are short to medium term and repaid through an exit, usually a sale, a refinance, a contract payment or business cash flow. The difference is what needs to happen at that point.

With a first mortgage, the exit usually means refinancing the whole balance to a bank or selling the property, because the loan now includes the old mortgage. With a second mortgage, only the second loan needs repaying; the bank loan carries on. Either way, a clear exit plan from the start is what makes the loan work. It's also worth checking your credit report with each of the credit reporters before you refinance back to a bank, so there are no surprises.

Key takeaways

• The difference between a first and second mortgage is priority on the record of title.
• A first mortgage suits mortgage-free property, replacing a bank loan in trouble or consolidating debts.
• A second mortgage suits owners with a good bank loan, especially a fixed one, and a short-term need.
• With a first mortgage refinance, the loan must cover the existing debt plus the new need.
• Get a written break cost quote before deciding whether to refinance a fixed bank loan.
• fundU offers both, from $20,000 to $1m, and can help you choose the right structure.
