The 7 Most Expensive Mistakes First-Home Buyers Make And How to Avoid Them

A quick heads-up before we dive in: This article is strictly for general informational purposes and does not constitute financial, legal, or tax advice. Every situation is entirely unique, and bank lending policies change frequently. Before making any decisions about your property journey, it is highly recommended that you seek independent advice from a qualified financial adviser.

Buying your first home is a steep learning curve. Unfortunately, it is a learning curve where making a rookie error doesn't just cost you a bruised ego—it can cost you thousands of dollars, or even the house itself.

Because you have never done this before, it is incredibly easy to fall into traps that seasoned property investors know to avoid. From wasting money on unnecessary reports to accidentally sabotaging your own bank approval, here are the top seven mistakes we see first-home buyers make, and exactly how to protect yourself.

1. Paying for Reports Before the Offer is Accepted

When you find a house you like, it is tempting to immediately ring a builder to get a building report and order a registered valuation. Do not do this.

Unless the property is going to Auction (where you must bid unconditionally), we generally recommend to not spend your own money on reports before the vendor has actually accepted your offer. What happens if you spend $800 on a building report, only for the vendor to flat-out reject your price? You have just burned $800 for nothing.

Instead, you put your offer in first, but you protect yourself by making the offer "Subject to a Building Report" and "Subject to Finance”, or any other conditions your solicitor recommends. This way, if there is something wrong with the reports or the property, or the bank says no, you can back out safely.

1.Sign the Agreement:

You and the vendor agree on a price, and you both sign the Sale and Purchase Agreement with your 'Subject to' conditions included.

2.Order the Reports:

You now have a set window (usually 5 to 10 working days) to pay for things like your building report, LIM, and registered valuation.

3.Go Unconditional:

If the reports come back clean and the bank is happy, you declare the contract unconditional. If the reports uncover a nightmare, you can use your conditions to walk away and cancel the contract safely.

2. Getting Emotionally Attached to a Flawed House

Buying a home is inherently emotional, but emotion is the absolute enemy of a sound financial decision.

Real estate agents are masters at staging homes. They use beautiful furniture, fresh paint, and perfectly placed lighting to make you fall in love. But as a buyer, you need to look past the scatter cushions and look at the bones of the property.

If a house has a fundamentally flawed layout, severe dampness issues, or is located directly next to a noisy industrial site, do not let your desperation to "just get on the ladder" blind you. You can change the paint colour, but you cannot change the location. If it is a bad house, walk away. There is always another one.

3. Falling for the "Too Good to Be True" Price Tag

If you are scrolling through listings and suddenly spot a massive, beautiful house in a great suburb for half the expected price, it is not your lucky day. It is cheap for a reason.

First-home buyers frequently get drawn in by two massive red flags:

• Leasehold Land: You are buying the physical house, but you are only renting the dirt it sits on. The ground rent can skyrocket when the lease renews, making the house unsellable.

• Monolithic Cladding: Homes built in the 1990s and early 2000s with a smooth, plaster-style finish are highly prone to "leaky building syndrome."

Banks are incredibly nervous about lending against these types of properties. If a price looks too good to be true, ring your mortgage adviser before you get your hopes up, there may be a reason it’s being offered cheaply.

4. The Real Estate Agent Deposit Trap

This is perhaps the most common logistical nightmare for a first-home buyer.

When you go unconditional on a house, the real estate agent will immediately ask you to transfer a cash deposit to their trust account (usually 10% of the purchase price).

The mistake? Most first-home buyers have their entire deposit locked up in their KiwiSaver account. KiwiSaver providers can take up to 15 working days to release your funds. If you have not planned for this, you will find yourself in breach of contract because you don't have the liquid cash to pay the agent on unconditional day.

The fix: Your solicitor can draft a specific clause into your offer stating that the deposit will be paid entirely from KiwiSaver upon settlement, or you can negotiate to pay a smaller, liquid cash deposit on the unconditional date, but make sure you make this part of your offer from the start.

5. Blind Loyalty to Your Childhood Bank

You have likely been with your current bank since your parents opened a youth account for you. You use their app, your wages go there, and you assume that because you are a loyal customer, they will give you the best mortgage.

They won't. Loyalty does not exist in modern banking.

This is especially critical if you have less than a 20% deposit. The rules for low-deposit lending vary wildly from bank to bank on any given week and some banks, including some of the biggest ones, don’t participate in things like the Kainga Ora First Home Loan Scheme. Your childhood bank might decline your application completely, while the bank across the street might approve you and hand you a $3,000 cash contribution just for signing up.

Never settle for the first answer your own bank gives you. Use a mortgage adviser to make sure you’re getting all the information before making a decision.

6. Buying a Car or Taking on Other New Loans Before Settlement Day

Once you get your unconditional mortgage approval, it feels like the finish line. You start measuring for curtains, buying new furniture on Afterpay, or maybe financing a new car to put in your new garage.

This is a fatal error.

The bank will often run a final, quiet credit check just days before settlement. If they see you have taken on new debt, your Uncommitted Monthly Income (UMI) changes. If that new car payment tips your budget over their strict stress-test limits, the bank can and will pull your mortgage funding at the eleventh hour.

Do not apply for a single credit card, store card, or loan at the very least before the property settles.

7. Assuming Pre-Approval Means You Can Buy Anything

A pre-approval is a fantastic tool—it tells you how much money the bank is willing to lend you. But first-home buyers often forget the second half of the equation: the bank also has to approve the house.

If you have a pre-approval for $800,000, you cannot just go and buy an $800,000 unconsented shed, a tiny 30-square-metre apartment, or a house with severe structural damage. The bank uses the house as security for the loan. If they don't like the house, your pre-approval means nothing.

Always send the property listing to your adviser before you make the offer, so we can ensure the bank will actually accept the property as security.
