Can I borrow against my house for my business in NZ?

For a lot of New Zealand families the house is the biggest asset they own, and at some point the business needs money the business alone can’t borrow. So the question lands on Mr’s desk in all sorts of forms: “Can I use the house?” “Will the bank let me?” “What happens if it goes wrong?” Let’s take them one at a time.

Can I really use my house for a business loan?

Yes. Residential property is one of the most common forms of security for business lending in New Zealand. Business.govt.nz even notes that new owners often end up borrowing more on their mortgage because other options are limited.

Property-secured business loans run from $20,000 to $5,000,000, and because the lender relies on the equity, it can often help when:

• the business is young or growing faster than its paperwork;
• the bank has said no;
• credit history has a few marks;
• IRD needs paying and time matters.

What are the ways to do it?

Route	How it works	Often suits
Top-up with your existing bank	Increase your home loan, use the extra for the business	Strong financials, no rush, bank happy with the purpose
New first mortgage	Refinance the whole property with a new lender	Larger needs, or moving away from your bank
Second mortgage	A separate loan registered behind your existing mortgage	Leaving your home loan untouched, quicker turnaround, short-term needs
Caveat-style security	Lender protects its interest by a caveat on the title rather than a registered mortgage	Small, short-term needs where speed and simplicity matter

Our pages on second mortgages and caveat loans explain those two routes in detail.

How much could I borrow against my house?

It comes down to usable equity: the value of the property, minus what’s already owed, within the lender’s loan-to-value limits. Second-mortgage and caveat lenders usually leave a bigger buffer than first-mortgage lenders, because they’re second in line. How much equity do I need? has a worked, illustrative example.

Who has to agree?

Everyone on the title. That includes:

• a partner or spouse who co-owns the home, even if they’re not in the business;
• trustees if the home is in a family trust — see using property owned by a family trust;
• sometimes your existing lender, depending on its mortgage terms.

Expect a requirement for independent legal advice for anyone giving security who isn’t the borrower. It protects them, and it protects the loan.

Wondering how this would work with your property? Ask a specialist — it doesn’t involve a credit check.

What are the risks?

Mr won’t sugar-coat this. When your home secures a business loan:

• if the business can’t repay, the lender can ultimately enforce its security over the house;
• the family’s housing is tied to the business’s fortunes;
• personal guarantees usually come alongside — read will I have to sign a personal guarantee?

Ways to keep that risk in proportion:

1. Borrow for a clear purpose that improves the business, not to cover losses you haven’t diagnosed.
2. Have a believable exit — refinance, sale, contract payment or steady repayments.
3. Talk it through at home before the lender’s paperwork arrives.
4. Keep a buffer for quiet months, tax dates and surprises.

What will the lender check on the property?

Usually title details, a current valuation (or the lender’s own assessment), rates and insurance, and the existing mortgage balance. We explain the full list on what does a lender check on my property?

An illustrative example: the bank said “not yet”

This case is invented, but Mr hears versions of it every month.

A couple in Christchurch own a home with a modest bank mortgage. One of them runs a growing commercial cleaning company that has just won a contract with a large facilities manager. The contract needs two new vans, equipment and six extra staff before the first invoice is paid. Their bank likes the business but wants the latest financial statements, which won’t be ready for three months.

Options on the table:

• Wait for the bank. Cheapest, but the contract starts in five weeks.
• Second mortgage on the home. Leaves the bank mortgage untouched, funds the start-up costs now, with the plan to refinance to the bank once the financial statements are filed and the contract income shows in the accounts.
• Unsecured facility. Possible for part of the need, sized on current turnover, but probably not the full amount.

They choose the second mortgage. The partner who isn’t in the business gets independent legal advice and is comfortable with the plan because there’s a signed contract and a clear refinance path. The term includes a few months’ buffer beyond the expected refinance date.

Questions to talk through at home first

Before any paperwork, Mr suggests sitting down together with these:

1. What exactly is the money for, and what does success look like?
2. What’s the worst realistic outcome, and could we live with it?
3. How will the loan be repaid, and by when?
4. What happens to the plan if the business has a bad quarter?
5. Does everyone on the title understand and agree?

If any answer is shaky, that’s the part to strengthen before you apply, not after.

Talk it through before you decide

Using your house is a big decision, and a good conversation beats a rushed one. Tell us roughly what the property is worth, what’s owing and what the business needs. There’s no credit check to ask, your details aren’t passed around a crowd of lenders, and a real person will explain the options plainly.

Please be accurate about the property’s ownership and existing mortgage on the form; it’s the difference between a quick path and a dead end. See what your home equity could do for your business.
