Buying your first home is a steep learning curve. Unfortunately, it is a curve where making a rookie error doesn't just bruise your ego—it can cost you thousands of dollars, or even cost you the house itself.
Because you haven't been through the process before, it is easy to stumble into traps that seasoned property investors have learned to sidestep. From burning cash on unnecessary inspection reports to accidentally derailing your own bank approval, here are the top seven mistakes we see first-home buyers make, and how to protect yourself.
1. Paying for Reports Before Your Offer is Accepted
When you find a house you love, the immediate temptation is to ring a builder for an inspection and order a registered valuation straight away. In most cases, you shouldn't do this.
Instead, you submit your written offer first, protected by standard contractual safety nets:
- Sign the Agreement: You and the vendor agree on the purchase price, signing a Sale and Purchase Agreement that includes explicit conditions—such as Subject to Finance, Subject to a Building Report, and Subject to Solicitor's Approval.
- Order the Reports: Once both parties have signed, your conditional window opens (typically 10 to 15 working days). This is when you pay for the building inspection, order the council LIM report, and instruct a valuer if the bank requires one.
- Confirm or Walk Away: If the reports are clean and the bank issues formal unconditional approval, your solicitor declares the contract unconditional. If the building report reveals severe structural defects or unconsented works, your conditions give you the legal right to negotiate repairs, request a price reduction, or walk away safely with your deposit intact.
2. Getting Emotionally Attached to a Flawed House
Buying a home is emotional, but letting emotions drive the process is the fastest way to make an expensive mistake.
Real estate agents and home stagers are experts at creating an inviting atmosphere. Strategic furniture, soft lighting, and fresh paint can make almost any property look appealing on a Sunday afternoon. But as a buyer, you have to look past the styling and examine the core structure.
If a property has a fundamentally awkward layout, poor sun positioning, severe dampness, or sits right against a busy transport corridor, do not let "property ladder fatigue" convince you to overlook it. You can renovate a kitchen and change the paint colour, but you cannot change the section or the street. If the fundamentals are poor, walk away. There is always another property.
3. Falling for "Too Good to Be True" Price Tags
If you are browsing listings and suddenly spot a large, renovated house in a sought-after suburb for half the expected market price, it isn't your lucky day. It is cheap for a specific reason.
First-home buyers often get caught out by two common scenarios:
- Leasehold Land: You own the dwelling, but you lease the land underneath it. When the ground lease comes up for renewal, the annual ground rent can jump drastically, creating an ongoing expense that can make the home difficult to resell or finance.
- Monolithic Cladding: Many homes constructed from the early 1990s to the mid-2000s using direct-fixed plaster systems without a drainage cavity are prone to weather-tightness failures ("leaky building syndrome").
Banks have exceptionally cautious credit policies around these property types. If a price looks unusually low, contact your mortgage adviser before getting invested—there is almost always a structural or tenure reason behind the discount.
4. The KiwiSaver Deposit Timing Issue
This is one of the most stressful administrative hurdles a first-home buyer can encounter.
When an agreement goes unconditional, the standard contract typically requires a deposit (often 10% of the purchase price). The catch? Most first-home buyers have the bulk of their funds sitting in KiwiSaver.
The Solution: Have your solicitor review the contract before you sign it. They can add a specific clause stating that the deposit will be satisfied via your KiwiSaver withdrawal and paid directly into your solicitor’s trust account, or negotiate a smaller cash holding deposit (e.g. $5,000) on unconditional day with the balance transferred at settlement.
It's also extremely important to understand the difference between your contract deposit and your bank deposit
5. Expecting Automatic Loyalty from Your Childhood Bank
Many buyers stay with the same bank their parents set them up with as teenagers. You have your everyday accounts and savings there, and it feels natural to assume they will offer you the most competitive home loan.
In practice, banks do not assess mortgage applications based on sentiment. They lend based on internal risk appetite, portfolio limits, and credit scoring at that specific moment in time.
This difference is particularly noticeable if you have less than a 20% deposit. Different lenders have varying appetites for low-deposit lending from month to month. Furthermore, several major retail banks choose not to participate in the Kāinga Ora First Home Loan scheme. Your current bank might decline your low-deposit application, while a competing lender down the road might approve it and offer a cash contribution towards your legal fees. Always compare criteria across multiple lenders before deciding.
6. Taking on New Debt Before Settlement Day
Receiving formal unconditional finance approval feels like crossing the finish line. Buyers often start ordering furniture, measuring up appliances, or taking out vehicle finance for their new driveway.
Maintain a complete freeze on new credit applications, buy-now-pay-later facilities, and major purchases until settlement is completed and the keys are in your hand.
7. Assuming Pre-Approval Means the Bank Will Fund Any Property
A pre-approval confirms how much a bank is prepared to lend you based on your financial position. However, every pre-approval is strictly subject to the bank approving the specific property you intend to buy.
Before submitting an offer or attending an auction, send the property listing, title details, and draft agreement to your adviser. We can run an initial check through bank property databases to confirm the security meets standard underwriting criteria.
