A Guide to Bridging Finance for NZ Buyers

You have found the next home, the offer needs to go in, and your current property has not sold yet. That is the moment a guide to bridging finance becomes useful. Bridging finance can give you room to buy before your existing home settles, but it is short-term lending with real costs and a clear exit plan required.

For the right borrower, it can stop a timing problem from becoming a missed opportunity. For the wrong situation, it can add pressure to an already expensive move. The key is understanding exactly how the numbers work before you commit.

What is bridging finance?

Bridging finance is a short-term loan that helps cover the gap between buying a new property and receiving the sale proceeds from the property you already own. It is commonly used when settlement dates do not line up, or when you need to make an unconditional offer on your next home before your current home has sold.

Rather than paying out your existing mortgage immediately, the lender may combine the debt on both properties for a temporary period. Once your current home sells and settles, the sale proceeds are used to reduce the lending. What remains becomes the long-term mortgage on your new home.

The practical appeal is simple: you may be able to secure a property without waiting for your sale to complete first. But the lender will look closely at whether you can afford the debt while you own two properties and what will happen if the sale takes longer than expected.

How bridging finance works in New Zealand

A bridging application usually starts with four figures: the expected sale price of your existing home, the purchase price of the new one, the mortgage currently secured against your home, and the total costs of moving. Those costs can include legal fees, valuation costs, real estate commission, moving expenses and, where relevant, renovation work.

A lender then assesses the peak debt. This is generally the highest amount you will owe while both properties are held. They will also assess the end debt, being the mortgage left after your existing property is sold and the sale proceeds have been applied.

For example, imagine you own a home expected to sell for $900,000 and have a $400,000 mortgage. You are buying a new home for $1,050,000, plus purchase costs. During the bridging period, your lending may need to cover the existing $400,000 debt and the funds needed to complete the new purchase. After the sale, the net proceeds from your old home reduce that temporary debt.

The figures are more involved than this simple example, because lenders build in selling costs and may use a conservative view of the sale value. That caution is not a nuisance. It is there to make sure the plan can cope if the market is slower or the sale price is lower than hoped.

Closed and open bridging loans

A closed bridge is used where there is a confirmed sale, usually with an unconditional contract and a known settlement date. This gives the lender greater certainty about when the temporary debt will be repaid.

An open bridge is used when your property has not sold yet. It can provide flexibility, but it normally requires a stronger overall position because there is no confirmed settlement date. The lender may want a valuation, evidence your property is being actively marketed, and a clear view of how the loan will be serviced if the sale takes longer than planned.

Neither option is automatically better. A closed bridge can be more straightforward, while an open bridge may help you act quickly. The right structure depends on your equity, income, property type, lending history and the strength of your sale plan.

The costs and risks to consider

Bridging finance is not simply a standard mortgage with a different name. Interest is often charged on a higher total balance during the bridging period, so even a short delay can be costly. Some loans may allow interest to be capitalised, meaning it is added to the loan balance rather than paid from your regular income. This can assist cash flow, but it also increases the debt.

You also need to plan for the possibility that your existing property sells for less than expected. A lower sale price means less money to reduce the bridge, leaving a larger end debt. If that end debt no longer fits the lender's affordability or loan-to-value requirements, you could need extra cash, a different loan structure or more time to resolve the position.

The main risks are worth confronting early:

• Your property takes longer to sell than expected, extending interest and holding costs.
• The sale price is below the lender's or your own estimate.
• You must meet repayments, rates, insurance and upkeep across two properties at once.
• Your financial circumstances change before the old property settles.

A good plan does not assume the best-case result. It allows for a realistic selling timeframe, agent commission, legal costs and some movement in price. If the deal only works when every number lands perfectly, it may not give you enough breathing room.

When bridging finance may suit

Bridging finance can suit an owner-occupier who has meaningful equity in their current home, stable income and a well-priced property that is likely to sell within a reasonable timeframe. It may also suit a buyer who has negotiated a favourable purchase but cannot make the timing work through a standard sale-and-purchase sequence.

It can be particularly useful in a competitive market where making an offer conditional on selling your own property could weaken your position. That said, removing conditions should never be treated casually. You still need confidence in the sale strategy and certainty that the temporary debt is manageable.

For investors, self-employed borrowers and people with variable income, the assessment may take more preparation. Lenders will want to understand the income behind the application, not just the asset position. Clear financial statements, up-to-date tax information and evidence of ongoing income can make a material difference.

Preparing a stronger bridging application

Start by being conservative about what your current property will sell for. An appraisal from an agent is helpful, but a lender may rely on a registered valuation or its own policy view. Ask what sale value has been used, how selling costs have been allowed for, and what the end debt will be if the sale is lower than anticipated.

Next, make the settlement dates visible. Your solicitor can help explain the timing on both contracts, but your lending plan should account for delays rather than assuming every date will run perfectly. If you are using an open bridge, have a genuine sales plan in place before you rely on it.

Finally, look beyond the interest rate. Compare the likely total interest during the bridge, any establishment or valuation fees, repayment requirements, the maximum bridging period and what happens if the old property has not sold by the agreed date. A cheaper-looking rate is not always the better solution if the structure is too restrictive for your circumstances.

Questions to ask before you proceed

Before signing a purchase agreement, ask your adviser or lender whether the application is being assessed as an open or closed bridge, what the peak and end debt will be, and what sale price assumptions have been used. You should also understand whether interest can be capitalised, how long the bridging period can run, and what repayment is required while both properties are held.

It is also sensible to ask about alternatives. In some cases, a longer settlement, a conditional offer, a deposit bond, a refinance or selling first may be more suitable. Bridging finance is useful because it creates flexibility, not because it removes the need for careful planning.

A move can be exciting without becoming financially rushed. Mortgage Time can help you test the numbers, understand lender requirements and build a lending structure around the sale plan, so you can make your next decision with clarity rather than pressure.
