Common Mortgage Misconceptions: Separating Fact from Fiction

Mortgages are a topic surrounded by half-truths, outdated advice, and well-meaning but incorrect guidance from friends and family. While New Zealand's lending landscape has changed significantly in recent years, many of the myths around home loans persist. At Chaperone, we regularly hear borrowers repeat assumptions that do not reflect how lending actually works today. Here are some of the most common misconceptions we encounter and what the reality actually looks like.

Misconception 1: You Need a 20% Deposit to Get a Mortgage

A 20% deposit is a widely cited benchmark, and for good reason - it unlocks better rates and avoids low-equity premiums. However, it is not the absolute minimum required to borrow. Many first-home buyers can enter the market with less, particularly through the First Home Loan scheme, which allows eligible buyers to purchase with as little as 5% deposit under a government-backed guarantee. LVR restrictions set by the Reserve Bank of New Zealand (RBNZ) limit high-LVR lending volumes, but they do not prohibit it entirely. It is worth understanding what your specific deposit position actually means, rather than assuming you must wait until you reach 20%.

Misconception 2: The Lowest Rate Is Always the Best Deal

Borrowers often fixate on the headline interest rate when comparing home loans, but rate is only one part of the total cost picture. Fees, break cost structures, flexibility provisions, and product features all affect the real cost of a loan over time. A product with a slightly higher rate but no break fees, a useful offset account, or generous extra repayment allowances may deliver better value depending on how you manage your money. Comparing loans on rate alone is a little like comparing cars only on fuel cost - the other factors matter too.

Misconception 3: Your Bank Will Always Give You the Best Deal

Many borrowers assume that loyalty to their main bank will be rewarded with preferential pricing. In practice, lenders tend to offer competitive rates to attract new business rather than to retain existing customers. Staying with the same lender without comparing the market at each refix is a common way to overpay on your mortgage. A mortgage adviser can access offers from multiple lenders and often identifies more competitive options than the one a borrower's existing bank is willing to put on the table without being asked.

Misconception 4: Pre-Approval Guarantees Finance

Pre-approval is a meaningful step in the process, but it is conditional rather than final. It indicates a lender's willingness to lend based on your financial position at the time of application, subject to a suitable property being found. The lender will still need to value the property and confirm it meets their lending criteria before granting full approval. Issues with the property itself, such as a low valuation, unusual construction type, or title complications, can affect whether the loan proceeds. Pre-approval is a strong signal, but it is not a guarantee.

Misconception 5: You Cannot Get a Mortgage If You Are Self-Employed

Self-employed borrowers do face additional scrutiny, but they are far from excluded from the mortgage market. Lenders typically require two years of financial statements and tax returns to assess income stability, and some will consider fewer years in certain circumstances. How income is presented in financial accounts can affect serviceability calculations, which is why working with a mortgage adviser who has experience with self-employed clients makes a genuine difference. Many self-employed borrowers successfully secure mortgages each year with the right preparation and documentation.

Misconception 6: Fixing Your Rate Always Protects You

Fixing your rate provides certainty over repayments for the fixed term, but it does not protect you from all risks. If you need to break a fixed-rate loan early - because you are selling, refinancing, or facing a change in circumstances - break fees can be significant depending on how rates have moved since you fixed. Some borrowers fix expecting protection and then face an unexpected cost when life changes. Understanding what happens at the end of the fixed term, and what breaking early would cost, is an important part of choosing any fixed-rate product.

Misconception 7: Paying Off Your Mortgage Early Is Always the Right Move

Reducing mortgage debt is generally a sound goal, but whether aggressively paying off your home loan is the best use of surplus funds depends on your broader financial picture. Other considerations, such as high-interest consumer debt, KiwiSaver contributions, or the opportunity cost of investment, can sometimes mean that directing every spare dollar to the mortgage is not the highest-value strategy. Many borrowers find it useful to discuss their full financial situation with a mortgage adviser or financial adviser rather than applying a one-size-fits-all rule.

Getting Accurate Information

The best way to avoid acting on a mortgage misconception is to get advice from someone with current, direct knowledge of the New Zealand lending market. At Chaperone, we connect borrowers with experienced mortgage advisers who can assess your specific situation and give you a realistic picture of your options. Good information at the start of the process saves time, money, and stress further down the track.
