Beginner's Guide to Buying a Holiday Home

How Holiday Home Lending Differs from Your Main Residence

Lenders treat holiday homes differently because you won't be living there full-time. Your bach will be classified as a second property, which means banks apply stricter lending criteria and typically require a larger deposit than they would for an owner-occupied home.

The key difference is that lenders assess your ability to service two mortgages simultaneously. They'll look at your existing debts, your income, and whether you can comfortably manage repayments on both properties without relying on rental income from the bach. Even if you plan to use booking platforms during peak ski season or summer, most banks won't include that potential income in their calculations unless you're purchasing the property as a dedicated investment.

Consider someone earning $120,000 annually who already has a $450,000 mortgage on their main residence in Frankton. They want to purchase a bach in Arrowtown. The bank will assess whether their income can service both the existing mortgage and the new loan, factoring in all living expenses and existing commitments. If the numbers show they're stretching too thin, the application won't proceed regardless of how much deposit they have saved.

Deposit Requirements for a Second Property

You'll need at least a 30% deposit for a holiday home, and some lenders require 35% or even 40%. This is substantially higher than the 20% typically required for an owner-occupied purchase, and it's non-negotiable with most mainstream banks.

The reason for the larger deposit is risk. If you encounter financial difficulty and need to sell a property, you'll prioritise keeping the roof over your head. Lenders know this, so they protect themselves by requiring more equity upfront in a second property. A low equity premium (LEP) is rarely available for holiday homes, even if you're willing to pay it.

For a bach priced at the current median in one of Queenstown's surrounding townships, you'd need genuine savings of at least 30% plus an additional amount to cover legal fees, building reports, and other settlement costs. That genuine savings component needs to have been in your account for at least three months, and lenders will ask for statements to verify the source. Gifted deposits are sometimes acceptable, but you'll need a statutory declaration from the person providing the funds confirming it's not a loan that needs to be repaid.

How Banks Calculate Your Borrowing Capacity

Your borrowing capacity for a holiday home depends on how much uncommitted monthly income you have after servicing your existing mortgage and covering all living expenses. Banks will stress-test your application at a higher interest rate than you'll actually pay, usually adding 2-3% to current rates, to ensure you can still afford repayments if rates rise.

This is where many buyers get caught out. You might be comfortably managing your current home loan with $2,000 in surplus income each month, but once the bank applies their calculator to a second mortgage, that surplus shrinks quickly. They'll also factor in rates, insurance, and maintenance costs for both properties.

In our experience, dual-income households have an advantage because banks view the income as more stable. If one person loses their job, the other income can still service the loans. Single-income applicants can still succeed, but they need a higher income relative to their total debt, and the deposit requirement may edge closer to 40% depending on the lender.

Fixed or Floating Rate for a Holiday Home

You have the same interest rate options for a bach as you do for your main residence: floating, fixed for one to five years, or a split between the two. The choice depends on your financial situation and how you plan to use the property.

A floating rate gives you flexibility to make extra repayments without penalty, which can be useful if you receive irregular income like bonuses or commissions. If you're planning to pay down the bach loan aggressively, keeping some or all of it on a floating rate lets you reduce the principal faster. The trade-off is that your repayments will fluctuate with rate changes.

Fixing part of the loan gives you certainty on repayments, which can be helpful when managing two mortgages. Many buyers split the loan, fixing a portion for two or three years to lock in a predictable repayment while leaving the remainder floating for flexibility. Your mortgage adviser can model different scenarios based on your income patterns and risk tolerance.

What Happens if You Rent the Bach Out Occasionally

If you plan to rent the property through Airbnb or Bookabach during periods you're not using it, you need to be upfront with your lender. Some banks will allow occasional short-term rentals without reclassifying the loan, but others will want to treat it as an investment property from the start, which changes the lending criteria.

The distinction matters because investment property loans are assessed differently. Banks will include a portion of the expected rental income in their serviceability calculations, but they'll also apply a higher interest rate and may require a slightly larger deposit. If you're not planning to rent the bach frequently or consistently, it's usually better to keep it classified as a holiday home and not rely on rental income in your application.

If you do rent it out and don't disclose this to your lender, you're technically breaching your loan agreement. That's unlikely to cause problems unless you default on the loan, but it's a risk worth avoiding. A quick conversation with your broker before you list the property on a booking platform can clarify what your lender allows.

How Equity in Your Main Home Can Help

If you have significant equity in your main residence, you can use some of it to boost your deposit for the bach. This is common in Queenstown, where property values have increased substantially over the past decade. Releasing equity reduces the cash deposit you need upfront, but it increases the debt secured against your main home.

As an example, suppose your main home in Queenstown is worth $1.1 million and you owe $400,000 on the mortgage. You have $700,000 in equity. The bank will typically let you borrow up to 80% of your home's value, which is $880,000. After repaying your existing $400,000 loan, you could access $480,000. That's enough to fund a 30% deposit on a bach and cover the associated costs, leaving your cash savings intact.

The downside is that you're now carrying more debt against your main home, and both properties are tied to your overall lending. If property values drop or your financial situation changes, you have less buffer. This approach works well for buyers with stable income and a long-term view, but it does increase your exposure.

Using a Mortgage Adviser for a Second Property Purchase

A mortgage adviser can compare lending policies across multiple banks because each lender has slightly different criteria for holiday homes. Some are more flexible on deposit size if you have a strong income and low existing debt. Others offer better interest rates but require a higher LVR. Without a broker, you're limited to the policies of whichever bank you approach first.

Advisers also structure the loan to suit how you'll use the property. If you're planning to pay down the bach quickly, they might recommend a revolving credit facility or an offset mortgage to reduce interest costs. If you want predictable repayments, they'll model fixed-rate options across different terms. The right structure can save you thousands over the life of the loan, and it's based on your specific circumstances rather than a one-size-fits-all approach.

You don't pay the adviser directly. They're compensated by the lender once your loan settles, so there's no upfront cost to you. That makes it worth having the conversation even if you're only in the early stages of considering a holiday home purchase.
