First Home Buyer Mistakes: 12 Errors That Cost Kiwis Thousands

Before you apply

1. House-hunting before pre-approval. You'll fall in love with homes you can't finance, and unconditional deadlines don't wait for paperwork. Approval first, open homes second.
2. Leaving credit limits open. Banks assess card and overdraft limits as debt even at $0 balance. Cut them months before applying.
3. BNPL and betting apps on statements. Three months of statements get read line by line. Afterpay habits and gambling transactions both shrink assessed affordability and raise questions.
4. Changing jobs mid-application. Probation periods complicate approvals. If a move is coming, time it around your purchase.
5. Applying scattergun. Multiple declined applications mark your credit file. One well-placed application beats four hopeful ones — placement is a broker's core skill.

During the hunt

6. Skipping the builder's report or LIM to 'save money'. A $700 report is the cheapest insurance in property. Auction purchases are unconditional — due diligence happens before bidding or not at all.
7. Bidding without knowing your true ceiling. Pre-approval conditions (like registered valuations at high LVR) can cap what you can actually pay. Know the conditions, not just the headline number.
8. Ignoring the KiwiSaver timeline. First-home withdrawals take time to process — apply well before settlement, or the money won't be there when your solicitor needs it.

At the finish line

9. Draining every dollar into the deposit. Settlement week has costs, and owning a home has surprises. Keep a buffer, even if it means borrowing slightly more.
10. Fixing 100% of the loan for one long term. Life changes; break fees punish rigidity. Splitting terms preserves options.
11. Forgetting insurance until the last day. Banks require house insurance from settlement — arrange it when you go unconditional, not the night before.
12. Taking the first 'no' as the answer. Different banks run different scorecards. Thousands of NZ buyers own homes today because a broker took a declined file to the right lender the second time.

Frequently asked questions

What's the single biggest first home buyer mistake in NZ?

Shopping before financing. Everything downstream — stress, missed homes, rushed due diligence — flows from not having a solid pre-approval and a known ceiling first.

Does using Afterpay stop me getting a mortgage?

Not by itself, but BNPL commitments count as debt, and heavy usage reads as budget stress in your statements. Clean statements for three months before applying.

Should I use all my savings for the deposit?

No — keep a post-settlement buffer for transaction costs and surprises. Settling broke turns a small repair into a credit-card debt.

If one bank declines me, is it over?

No. Banks' credit policies differ meaningfully. Find out the real reason, fix what's fixable, and have the file placed with a lender whose policy fits it.
