How to Buy a Property With Just a 5% Deposit (BNZ's Low Deposit Home Loan Explained)
For a lot of aspiring first home buyers, the biggest hurdle isn't affording the mortgage repayments. It's saving the deposit. With house prices where they are, a traditional 20% deposit can take years to save. That's why low deposit lending options are worth understanding.
BNZ currently offers home loans up to 95% of a property's value (95% LVR), meaning you may only need a 5% deposit to get into your first home. Here's what you need to know before you get started.
Who Can Access This
This offer is for owner-occupiers only. It's designed to help people buy a home to live in, not to purchase an investment property. It's also currently open to anyone, not just existing BNZ customers, although BNZ has occasionally limited it to existing customers in the past, so it's worth checking current eligibility before you get too far into the process.
What It Costs You
Borrowing at a higher LVR comes with a trade-off: a low equity margin (LEM) added on top of the standard interest rate. At 95% LVR, this margin is currently 1.20%. Once you've paid down the loan (or the property's value has grown) enough that you have 10% equity, this margin drops to 0.75%. As you continue to pay off the loan and build equity beyond 20%, the margin falls away completely and you move onto standard rates.
Your Deposit Needs to Be Genuine Savings
This is a key condition. Your 5% deposit can't be a gift from family, it needs to come from genuine savings, which BNZ defines as funds you've saved yourself, your KiwiSaver balance, or proceeds from the sale of another property. This is worth planning for early, since lenders will want to see a track record of saving, not just a lump sum that's appeared in your account recently.
Timing Matters
Unlike standard home loan applications, there's no pre-approval available for this product. You can only apply once you have a signed Sale and Purchase agreement in hand, or ahead of a forthcoming auction. This means you'll need to have done your numbers and know roughly what you can afford before you start looking seriously at properties, since you won't have a pre-approval to lean on while house hunting.
A Registered Valuation Is Required
As a condition of approval, BNZ will require a registered valuation on the property. This is an added cost to factor into your budget, and it protects both you and the bank by confirming the property is actually worth what you're paying for it.
What This Looks Like in Practice
Let's say you've found an $800,000 home. At 95% LVR, you'd need a $40,000 deposit, with BNZ lending the remaining $760,000.
Based on BNZ's current one-year fixed rate of 4.99%, plus the 1.20% low equity margin (bringing the effective rate to 6.19%), and assuming a standard 30-year loan term, your weekly repayments would come to approximately $1,073.
Once you've built up 10% equity — either through repayments or house price growth — the margin drops to 0.75%, which would bring your repayments down accordingly.
Rates are subject to change and this figure is illustrative only, your actual rate, repayments, and eligibility will depend on your individual circumstances. It's worth speaking with a mortgage adviser or BNZ directly to get numbers tailored to your situation.
Is It Right for You?
A 95% LVR loan can be a genuine pathway into home ownership if saving a full 20% deposit feels out of reach. But it's worth going in with eyes open about the higher interest cost in the early years, and the fact that a smaller deposit means less buffer if property values dip. Weigh this up against your own financial situation, and consider talking to an independent mortgage adviser to compare your options.
