15 Mistakes First Home Buyers Make (And How to Avoid Them)

I have sat across the table with enough first home buyers now to see the same handful of mistakes come up again and again. None of them are complicated once someone points them out, but they are genuinely easy to walk into if nobody has explained them to you first. Here is the full list, in the order they tend to actually happen.

1. House hunting before pre-approval

This is the most common one by a wide margin. Buyers start browsing listings, fall for a property, then find out afterwards it is outside what they can actually borrow. Get pre-approved first, then search with a real number in mind. It also means you can act quickly and confidently once you do find the right place, rather than starting the finance conversation from scratch under time pressure.

2. Spending the whole deposit

Your deposit needs to cover more than just the deposit itself. Legal fees, building inspections, LIM reports and moving costs all come out of the same pool of savings, so leave a buffer rather than stretching every dollar into the purchase price.

3. Ignoring settlement costs

Beyond the obvious legal fees, there are often smaller costs that catch buyers by surprise, rates adjustments, insurance starting from settlement day, and sometimes body corporate fees if you are buying into a unit title property. None of these are huge individually, but they add up if you have not planned for them.

4. Accepting the first offer

Whether it is your bank's first rate offer or the first lender you spoke to, taking it without comparing means you genuinely do not know if you are getting a competitive deal. Different lenders assess the same person differently, sometimes significantly so, which is exactly why running your situation past more than one option, or through an adviser who already compares across several, tends to pay off.

5. New debt before settlement

A new car loan or a big jump in credit card spending between pre-approval and settlement can reduce what you are able to borrow, sometimes enough to affect the purchase itself. Keep your financial situation steady until the keys are in your hand.

6. Fixing the whole loan blindly

Locking your entire mortgage into one fixed term without thinking it through can leave you with less flexibility than a split structure would have given you. It is worth a proper conversation about this rather than defaulting to whatever the bank suggests, since the right structure depends on your own plans, not a generic default setting.

7. Skipping the building inspection

Making an offer without a building inspection condition can look more competitive on paper, but it removes one of your biggest protections. What you save by skipping it is small compared to what an undisclosed issue could cost you later, and a good inspector will often flag things a buyer would never notice on a standard viewing.

8. Ignoring the LIM report

A LIM report can flag consent issues, hazards, or council records that are not obvious just from viewing a property. Treating it as a formality rather than actually reading it means you can miss something genuinely important before you are committed.

9. Underestimating ongoing costs

Buyers often budget carefully for the mortgage repayment itself, then forget to properly account for rates, insurance, and maintenance on top of it. These are real, ongoing costs of owning a home, not optional extras, and they do not disappear once settlement is done. Building them into your budget from the start avoids an unpleasant surprise in your first few months of ownership.

10. Forgetting moving costs

Removalists, connecting utilities, and simply furnishing a new place all cost more than people expect. It is a small thing on its own, but it is one more reason not to spend your entire deposit down to the last dollar.

11. Leaving KiwiSaver too late

KiwiSaver withdrawals are not instant. Starting the process only once you are under a tight settlement deadline creates unnecessary stress. Start the conversation with your provider as soon as you are seriously looking.

12. Not reading the conditions properly

Every condition in your Sale and Purchase Agreement has a deadline attached to it. Not understanding what you have actually agreed to, or missing a deadline, can put your deposit or the whole purchase at risk. Have your solicitor walk you through it properly.

13. Overlooking LVR implications

A smaller deposit means a higher loan to value ratio, which can mean a higher interest rate through a low equity margin, and sometimes more restricted lending options. Understanding this upfront helps you weigh whether waiting to save a bit more genuinely makes a difference to your situation, or whether the low deposit options available to you make more sense than waiting.

14. Letting emotions set the budget

It is easy to fall in love with a property and stretch beyond your pre-approved number to secure it. This is exactly the situation pre-approval is meant to protect you from. If a property is outside your number, it is worth walking away, even when it is hard to.

15. Never reviewing the loan again

Settlement is not the finish line. Rates, your income, and your goals all change over time, and a mortgage set up five years ago may no longer be the right structure for where you are now. Review it, ideally every time your fixed term comes up, rather than letting it run on autopilot for the life of the loan.

A pattern worth noticing

Looking back over this list, most of these mistakes fall into one of two categories. Either something was rushed that deserved a bit more time, house hunting before pre-approval, skipping an inspection, not reading the conditions properly, or something was treated as a one off event rather than an ongoing relationship, the loan itself, your budget, your KiwiSaver timing. The buyers who tend to have the smoothest experience are usually the ones who slow down slightly at the start and stay engaged slightly longer at the end, rather than sprinting through the middle and then forgetting about it entirely once the keys are in hand.
