What Is Loan-to-Value Ratio (LVR) and Why Does It Matter?
A practical New Zealand guide to calculating your LVR, understanding current lending limits and seeing how your deposit can shape your mortgage options.
Loan-to-value ratio – usually shortened to LVR – is one of the first numbers a lender considers when assessing a home-loan application. It compares the amount you want to borrow with the value of the property securing the loan.
That sounds simple, but your LVR can influence much more than the size of your deposit. It may affect which lenders will consider your application, whether your loan sits within a bank’s standard policy, the interest rate or low-equity cost you may be offered, and how exposed you are if property values fall.
This guide explains how LVR works in New Zealand, what the current Reserve Bank restrictions mean, and why two borrowers purchasing similarly priced homes can receive very different mortgage options.
What does loan-to-value ratio mean?
Your loan-to-value ratio is the percentage of a property’s value that is covered by your mortgage. The part not covered by borrowing is generally your deposit when purchasing, or your equity if you already own the property.
For example, imagine you are purchasing a home valued at $900,000:
- You contribute a $180,000 deposit.
- You borrow $720,000.
- Your mortgage equals 80% of the property’s value.
- Your LVR is therefore 80%.
A lower LVR means you are contributing more of your own money or equity. A higher LVR means the lender is funding a greater portion of the property. From a lender’s perspective, a higher LVR generally represents more risk because there is a smaller equity buffer if the home must be sold during a market decline.
How do you calculate LVR? The basic formula is: Loan amount ÷ property value × 100 = LVR percentage
Which property value does the bank use?
The calculation is not always based on the number you expect. A lender may use the purchase price, a registered valuation, an automated valuation or another figure accepted under its policy. If a valuation comes in below the agreed purchase price, your effective LVR may rise because the lender is measuring the loan against a lower value.
Suppose you agree to pay $900,000 and plan to borrow $720,000. If the lender accepts a value of only $850,000, the resulting LVR is about 84.7%, not 80%. That change may move the application into high-LVR territory.
Important: LVR measures the loan against the property. It does not show whether repayments are affordable. Lenders separately assess income, expenses, existing debt, credit conduct and debt-to-income position.
What are the current LVR restrictions in New Zealand?
The Reserve Bank of New Zealand sets LVR restrictions for registered banks. These are often misunderstood as a rigid deposit rule applying identically to every borrower. They are better described as bank-level “speed limits”: they restrict how much of a bank’s new residential mortgage lending can fall into high-LVR categories.
As maintained in August 2026:
- Owner-occupiers: loans above 80% LVR are high-LVR. Banks may allocate up to 25% of new owner-occupier lending above that threshold.
- Property investors: loans above 70% LVR are high-LVR. Banks may allocate up to 10% of new investor lending above that threshold.
This does not mean every owner-occupier must have exactly a 20% deposit or that every investor must have exactly 30%. It means lending above those LVR thresholds is limited across each bank’s new lending. A lender can still decline an application below the threshold, or potentially approve an application above it, depending on capacity, policy, the strength of the application and any applicable exemption.
Are any loans exempt from the restrictions?
Yes. Reserve Bank exemptions include Kāinga Ora loans such as First Home Loans, qualifying construction and new-build lending, certain refinancing that does not increase the loan amount, portability, bridging finance and some property-remediation lending. An exemption from the macroprudential restriction is not guaranteed approval: the lender still applies its own eligibility, affordability and credit criteria.
Eligible first-home buyers may be able to use a Kāinga Ora First Home Loan with a deposit from 5%, through participating lenders. Eligibility requirements and lender criteria apply. Read our first-home buyer guide and guide to mortgage deposits before deciding what pathway may suit you.
Why does your LVR matter?
1. It can affect your lender options
A borrower at or below 80% LVR will generally sit within a wider range of standard owner-occupier policies than someone borrowing 90% or 95%. High-LVR lending is available in some situations, but places can be limited and lender rules differ. A mortgage broker can compare which lenders are actively considering borrowers in your position.
2. It can affect interest rates and low-equity costs
Some lenders apply a low-equity margin, premium or other cost when the loan exceeds a certain proportion of the property value. These costs reflect the additional lending risk. The structure varies: a margin may be added to the interest rate, while a premium may be charged separately or added to the loan. Always compare the total cost, not only the advertised rate.
3. It changes your equity buffer
A 20% deposit gives you more protection against a fall in the property’s value than a 5% deposit. If you purchase a $700,000 home with a $35,000 deposit, your starting LVR is 95%. A relatively small market decline could reduce or eliminate your equity, making it harder to sell, refinance or switch lenders without contributing additional funds.
4. It may influence refinancing or a top-up
LVR restrictions generally apply to new lending rather than retrospectively to an existing mortgage. However, a refinance or top-up can require a fresh valuation and assessment. If the total lending pushes the property above a lender’s acceptable LVR, your options may narrow. See our guides to refinancing a mortgage and home-loan top-ups.
5. It is only one part of approval
A low LVR does not automatically mean you can borrow. Banks also consider whether the repayments are sustainable, your income stability, living expenses, existing liabilities, account conduct and credit history. Debt-to-income restrictions operate alongside LVR restrictions. Our article on debt-to-income ratios in New Zealand explains that separate calculation.
Comparing common deposit and LVR levels
| Deposit or equity | Mortgage | LVR |
|---|---|---|
| 5% | 95% | 95% LVR |
| 10% | 90% | 90% LVR |
| 20% | 80% | 80% LVR |
| 30% | 70% | 70% LVR |
| 40% | 60% | 60% LVR |
These are simplified examples. The accepted value, capitalised fees and loan structure may affect the final calculation.
How can you reduce your LVR?
If your current LVR limits your options, the solution is not always “wait until you have 20%.” The right strategy depends on your timeframe and circumstances. Possibilities include:
- Build a larger deposit: regular saving, reducing discretionary spending or directing windfalls towards the purchase.
- Consider a lower-priced property: the same deposit represents a larger percentage of a less expensive home.
- Check eligible deposit sources: KiwiSaver first-home withdrawals, gifts or other accepted sources may help, subject to rules and lender evidence requirements.
- Investigate First Home Loan eligibility: eligible applicants may purchase with a deposit from 5% through participating lenders.
- Repay principal: existing owners can improve their LVR as the mortgage balance reduces.
- Add value carefully: renovations may improve a property’s value, but the increase is not guaranteed to match the money spent.
Before making an offer, consider arranging mortgage pre-approval. It can clarify the lender’s accepted deposit, likely valuation requirements and any conditions attached to high-LVR lending.
Frequently asked questions
- Is an 80% LVR good?
For an owner-occupier, 80% LVR means a 20% deposit or equity contribution. It usually places the loan outside the Reserve Bank’s high-LVR owner-occupier category, but approval and pricing remain subject to lender criteria.
2. Can I buy a home with less than a 20% deposit?
Potentially. Banks can make a limited proportion of owner-occupier lending above 80% LVR, and certain loans are exempt. Kāinga Ora First Home Loans may allow eligible buyers to purchase with a deposit from 5%. Availability is not guaranteed.
3. Does a high LVR mean a higher interest rate?
It can. Some lenders apply low-equity margins or premiums, and high-LVR borrowers may have fewer pricing options. Ask for the total cost of borrowing, including fees and any rate margin.
4. Does LVR use the purchase price or registered valuation?
The figure depends on lender policy and the transaction. A lender may use the purchase price, registered valuation or another accepted valuation. If the accepted value is lower than expected, your LVR increases.
5. Can my LVR change after I buy?
Yes. It can fall as you repay principal or if the property value rises. It can rise if you borrow more or the accepted value falls. Market estimates do not automatically change your contracted loan, but a new valuation may matter when refinancing or topping up.
6. Are new builds exempt from LVR restrictions?
Qualifying construction loans and purchases of newly built homes from a developer within the Reserve Bank’s specified period can be exempt. Lender policies and normal approval criteria still apply.
Not sure what your LVR means for your application?
A mortgage broker can calculate your position, explain potential low-deposit pathways and compare lender policies based on your circumstances.
