Buying a first home

What a bank will actually lend you, and the traps in off the plans, leasehold, unit titles and buying with family.

44 situations worked through, 43 of them with the sums shown. Each one links to the guide that sets out the rules behind it, and that guide is where any rate or threshold is kept current.

The people in these situations are illustrations written to show how the rules land on somebody, not real customers and not case histories. The arithmetic is real and the rules are real; the names and the circumstances are made up to teach.

Buying a Home With Family

Aroha and Mia: two friends, unequal deposit

Aroha and Mia buy a $760,000 townhouse together. Aroha contributes a $120,000 deposit and Mia contributes $40,000, so the combined deposit is $160,000 and the loan is $600,000. They agree to split the mortgage repayments equally and hold the title as tenants in common, with shares that reflect what each of them puts in.

  1. Loan split equally: $600,000 / 2 = $300,000 each
  2. Aroha's total contribution: $120,000 deposit + $300,000 loan = $420,000
  3. Mia's total contribution: $40,000 deposit + $300,000 loan = $340,000
  4. Aroha's share: $420,000 / $760,000 = 55.3%

Mia's share: $340,000 / $760,000 = 44.7%

Tama and Rewi: survivorship changes who inherits

Brothers Tama and Rewi buy a $800,000 home together, contributing equally. Tama has a will leaving everything he owns to his daughter. Some years later Tama dies. What happens to the home depends entirely on how they held the title.

  1. The right of survivorship applies, so Tama's interest passes automatically to Rewi
  2. Rewi becomes the sole owner of the whole $800,000 home

Tama's daughter receives nothing from the home, whatever his will says

💡 Match the structure to your intentions

The two outcomes could not be more different, and both are perfectly legal. If Tama wanted his daughter to inherit his stake, joint tenancy was the wrong choice. Friends and family buying together usually want tenants in common precisely so each person's share passes to their own family. Review the title and your will together, and update both if your wishes change.

Sam wants out: using the first right of refusal

Sam, Priya and Jack bought a home together as tenants in common in equal thirds. It is now worth $900,000 with a $450,000 mortgage, so the equity is $450,000. Sam is moving overseas and wants to sell his share. Their co-ownership agreement gives the others a first right of refusal at a valuer-assessed price.

  1. Equity: $900,000 value − $450,000 mortgage = $450,000
  2. Sam's share: $450,000 / 3 = $150,000

Priya and Jack can buy Sam's third for $150,000

⚠️ Releasing the departing owner from the loan

Buying Sam's share is only half the job. Until the mortgage is refinanced into Priya and Jack's names, Sam stays jointly and severally liable to the bank even though he no longer owns any of the home. If the others could not afford to buy him out, and there were no workable exit clause, Sam could apply to the court under section 339 of the Property Law Act 2007 to force a sale. A clear agreement avoids that slow and costly path.

A parent's $100,000: gift versus documented loan

A parent puts $100,000 toward their daughter's first home. The daughter adds $20,000 of her own savings and borrows $480,000 to buy a $600,000 home. A few years later she has been in a de facto relationship for over three years, and the couple separate. Assume the equity at separation is $150,000. The result depends on whether the $100,000 was gifted or lent.

  1. The home is the couple's family home, so the $150,000 equity is relationship property
  2. Relationship property is generally split 50/50: $150,000 / 2 = $75,000 each

About $50,000 of the parent's $100,000 effectively ends up with the ex-partner

💡 The paperwork protects the family money

The only difference between these outcomes is a written loan agreement signed before the money changed hands. Documenting the help as a loan, ideally with legal advice on securing it, keeps the parent's contribution out of the relationship-property split. The figures here are illustrative and the law is nuanced, so a contracting-out agreement and advice from your own lawyer are the safe way to lock this in.

Buying an Apartment: Unit Titles

Mereana: checking the maintenance fund balance

Mereana is looking at a unit in a 30-unit building. The long-term maintenance plan in the disclosure forecasts $900,000 of works over the next 10 years. The long-term maintenance fund currently holds $120,000, and the building collects $60,000 a year in long-term maintenance levies.

  1. Fund in 10 years at the current rate: $120,000 + (10 × $60,000) = $720,000
  2. Forecast cost of works: $900,000
  3. Projected shortfall: $900,000 - $720,000 = $180,000

Likely special levy per unit (even 30-way split): $180,000 ÷ 30 = $6,000

Daniel: a special levy hiding in the minutes

Daniel reads the three years of general meeting minutes in the pre-contract disclosure. A resolution passed last year approves re-cladding the building at an illustrative $2,400,000, funded by a special levy. The unit he wants has an ownership interest of 3.5%.

  1. Total special levy: $2,400,000
  2. His unit's ownership interest: 3.5%
  3. His share: $2,400,000 × 3.5% = $84,000

A levy already approved that he would inherit on settlement

💡 The minutes are where the surprises hide

The seller may not raise the levy in conversation, but it is right there in the disclosed minutes. Because the levy was approved before Daniel buys, he could inherit the $84,000. He should negotiate the price down to reflect it, agree in writing who pays, or walk away.

Sione: comparing two apartments' annual levies

Sione is deciding between two similar apartments. Apartment A charges $6,500 a year in levies. Apartment B charges $3,800. B looks like the bargain, so he checks how each levy is split.

  1. Apartment A: $4,500 operating + $2,000 to the maintenance fund = $6,500
  2. Apartment B: $3,500 operating + $300 to the maintenance fund = $3,800
  3. Maintenance saved over 10 years in A: 10 × $2,000 = $20,000
  4. Maintenance saved over 10 years in B: 10 × $300 = $3,000

B under-provisions by about $20,000 - $3,000 = $17,000 per unit over the decade

Ana: disclosure-statement red flags

Ana works through the pre-contract disclosure for a 40-unit building and finds four warning signs at once.

  1. Only one year of financial statements is provided, not the required three years
  2. The minutes reference a weathertightness claim on the building
  3. The body corporate discloses actual knowledge of an earthquake-prone rating
  4. Several owners are in levy arrears, straining the funds
⚠️ Incomplete disclosure is itself a red flag

The missing two years of financials is not a minor slip, it is a possible ground to delay or cancel, and a sign the seller may be hiding something. Combined with a weathertightness claim, an earthquake-prone rating and arrears, Ana is looking at a building with serious, expensive problems. Her solicitor should review everything before she goes near settlement.

Buying Off the Plans

Priya and Sam - 10% deposit on a $700,000 apartment

Priya and Sam sign to buy a new apartment off the plans for $700,000. The developer asks for a 10% deposit, held in the developer's lawyer's trust account until settlement.

  1. Purchase price: $700,000
  2. Deposit at 10%: $700,000 × 0.10 = $70,000
  3. Held in trust until settlement, refundable on valid cancellation
  4. Balance due at settlement: $700,000 - $70,000 = $630,000

They tie up $70,000 now, and must fund $630,000 (deposit plus loan plus savings) at settlement

💡 What this commits them to

The $70,000 is locked away for the whole build, which could be well over a year. They need to be sure they can leave it tied up that long and still cover their living costs and any surprises in the meantime.

The same calculation on its own, with others like it

Priya and Sam - a valuation shortfall at settlement

Eighteen months later the apartment is finished. Priya and Sam had planned on an 80% loan. When they signed, an 80% loan on $700,000 would have been $560,000, leaving $140,000 of their own money to find, of which the $70,000 deposit was already paid. But the market has softened, and the bank's registered valuation comes in at $650,000. The bank lends 80% of the lower of price or valuation.

  1. Contract price (still owed in full): $700,000
  2. Planned loan at signing: $700,000 × 0.80 = $560,000
  3. Valuation at completion: $650,000
  4. Actual loan: $650,000 × 0.80 = $520,000
  5. Own funds now needed: $700,000 - $520,000 = $180,000
  6. Deposit already paid: $70,000

Extra cash to find at settlement: $180,000 - $70,000 = $110,000

⚠️ A $50,000 valuation drop became a $40,000 cash call

Their plan needed $70,000 on top of the deposit. The lower valuation lifts that to $110,000, an extra $40,000 they must find in cash, because they still owe the developer the full $700,000. If they cannot raise it, they risk failing to settle and losing the deposit. This is why an off-the-plan buyer needs a real cash buffer.

Tane - a sunset-clause cancellation

In 2024 Tane signs to buy a new townhouse off the plans for $650,000, paying a 10% deposit of $65,000 into trust. The contract has a sunset date 24 months out. The build runs late and the sunset date passes. The contract lets the developer cancel under the sunset clause.

  1. Contract price: $650,000
  2. Deposit paid into trust: $650,000 × 0.10 = $65,000
  3. Developer cancels after the sunset date. No NZ law requires Tane's consent.
  4. Deposit returned in full: $65,000
  5. Equivalent new townhouses now sell for: $720,000

To buy again, Tane faces $720,000 - $650,000 = $70,000 more, plus a fresh deposit and lost time

💡 What would have protected Tane

Tane gets his deposit back but no compensation, and the market has moved beyond him. Negotiating a buyer-only sunset right, or a term requiring his written consent before the developer could cancel, would have stopped the developer walking away to re-sell at the higher price. That negotiation had to happen before signing.

Mere - the new-build deposit advantage

Mere is buying an $800,000 owner-occupier home. For an existing home her bank would want a 20% deposit. Because a new build is exempt from the LVR restrictions, the bank is willing to lend up to 90% on the new build.

  1. Purchase price: $800,000
  2. Existing-home deposit at 20%: $800,000 × 0.20 = $160,000
  3. New-build deposit at 10%: $800,000 × 0.10 = $80,000
  4. New-build loan at 90%: $800,000 × 0.90 = $720,000

Upfront deposit saving on the new build: $160,000 - $80,000 = $80,000

Earthquake-Prone Buildings

Priya: a 30% NBS rating on the apartment she wants

Priya is buying a unit in an eight-unit 1975 concrete block listed at $480,000. The disclosure documents reveal a seismic rating of 30% NBS. Because 30% is below 34%, the building is legally earthquake-prone, carries an EPB notice and is on the register.

  1. Illustrative cost to strengthen the block from 30% to 67% NBS: $1,200,000
  2. Priya's share for an even eight-unit split: 100% ÷ 8 = 12.5%
  3. Her likely special levy: $1,200,000 × 12.5% = $150,000

Effective cost of the apartment: $480,000 + $150,000 = $630,000

The same calculation on its own, with others like it

The Wai Street body corporate: a strengthening special levy

A 20-unit unreinforced masonry building rated at 25% NBS must be strengthened to 70% NBS. The body corporate approves the work at an illustrative $3,000,000 and applies the long-term maintenance fund toward it.

  1. Total strengthening cost: $3,000,000
  2. Long-term maintenance fund applied: $400,000
  3. Amount to raise by special levy: $3,000,000 - $400,000 = $2,600,000
  4. Owner A, a larger unit at 6% entitlement: $2,600,000 × 6% = $156,000

Owner B, a smaller unit at 4% entitlement: $2,600,000 × 4% = $104,000

💡 Shares follow unit entitlement, not an equal split

Because the levy is split by unit entitlement, the larger unit pays more. A healthy maintenance fund cut the amount to raise from $3,000,000 to $2,600,000, which is exactly why the state of that fund matters so much when you buy into a building that may need strengthening.

Tom: the insurance and finance impact

Tom has an offer accepted on a unit in a 28% NBS building at $420,000 with a 20% deposit. He needs a $336,000 mortgage. Then the insurance and finance checks begin.

  1. Illustrative premium for a comparable sound building: $2,500 per year
  2. Insurer's loading for the earthquake-prone rating: about 60%
  3. Loaded premium, if offered at all: $2,500 × 1.6 = $4,000 per year

Extra insurance cost: $4,000 - $2,500 = $1,500 per year, possibly with earthquake cover excluded

⚠️ Insurance is the choke point

For earthquake-prone buildings the deal often fails at insurance, not the rating itself. No insurer means no lender, because banks require the security to be insured. Make your offer conditional on both insurance and finance, and confirm cover in writing before you commit.

Aroha: earthquake-prone at 30% NBS versus 70% NBS

Aroha is choosing between two similar-looking apartments. Building X is rated 30% NBS and priced at $450,000. Building Y is rated 70% NBS and priced at $520,000. The 70% figure worries her because it is not 100%.

  1. Below the 34% line, so on the EPB register with a notice and a deadline
  2. Illustrative strengthening share for her unit: $150,000
  3. Insurance and finance likely to be difficult

Effective cost: $450,000 + $150,000 = $600,000, plus finance risk

💡 70% NBS is fine, 30% NBS is the problem

The 70% NBS rating is not a defect. It is well above the legal line and above the level most insurers and banks are comfortable with. Building Y costs $70,000 more on paper but avoids a roughly $150,000 strengthening exposure and the finance and insurance headaches of Building X. Do not let "not 100%" scare you away from a sound building, and do not let a low price lure you into an earthquake-prone one.

Leasehold Property Explained

A CBD apartment facing a ground-rent review

Ben is looking at a leasehold apartment priced at $400,000. The ground rent is currently $18,000 a year, set at 5% of the apartment's share of the land value, and reviewed every 7 years. The next review is due soon, and the land has risen so that his share is now assessed at about $500,000.

  1. Current ground rent: $18,000 a year
  2. New rent at review: 5% x $500,000 = $25,000 a year
  3. Increase: $25,000 − $18,000 = $7,000 a year, about $583 a month more

Ground rent alone rises to $25,000 a year, before mortgage, rates or body corporate levies

⚠️ Add the levies, then look again

This apartment is a unit title on leasehold land, so on top of the $25,000 ground rent Ben also pays body corporate levies, say $8,000 a year, taking his fixed holding cost to about $33,000 a year before his mortgage. Buying just before a review means inheriting the higher rent almost at once. Ben should confirm the review date and the new assessed land value before deciding what the apartment is really worth to him.

Freehold versus leasehold: the saving that disappears

Priya compares two similar apartments. The freehold one is $650,000. The leasehold one is $400,000, so the price gap is $250,000, which looks like a big saving. The leasehold apartment has ground rent of $20,000 a year.

  1. Upfront price gap: $650,000 − $400,000 = $250,000
  2. Ground rent: $20,000 a year
  3. Years to spend the saving in rent: $250,000 / $20,000 = 12.5 years

After about 12.5 years the ground rent alone has consumed the entire upfront saving, and Priya still owns no land

💡 Compare total cost, not sticker price

The freehold buyer owns land that can appreciate, while the leasehold buyer pays rent that can rise and builds no land equity. Once you count ground rent over the years you plan to stay, and remember that reviews usually push it higher, the leasehold saving shrinks fast. Compare the total cost of ownership and the equity you will hold at the end, not just the day-one price.

A 21-year review: a documented sharp jump

Some Auckland leasehold homes sit on land where the ground rent resets to a percentage of the current land value only once every 21 years. On Cornwall Park land, one home's ground rent was documented rising from about $8,300 a year to about $73,750 a year at a scheduled 21-year review. This example uses those figures to show the scale.

  1. Old ground rent: about $8,300 a year
  2. New ground rent at review: about $73,750 a year
  3. Increase: $73,750 − $8,300 = $65,450 a year, about $5,454 a month more

That is roughly 8.9 times the old rent, in a single step

⚠️ A long gap between reviews hides a big step

Infrequent reviews feel comfortable because the rent sits still for years, but they store up a large adjustment. When 21 years of land-value growth land in one review, the rent can multiply. Before buying on a long-review lease, find out when the last review was, when the next one falls, and what the land is worth now, so you can estimate the next step rather than be shocked by it.

A short lease: hard to finance, hard to resell

Marama wants to buy a leasehold townhouse for $350,000. It is on a fixed-term lease with only 8 years left to run. Her bank is willing to lend $300,000, but only if the loan is repaid within the remaining lease, so over 8 years rather than a normal 25. Assume an illustrative 6.5% interest rate.

  1. $300,000 over 25 years at 6.5%: about $2,026 a month
  2. $300,000 over 8 years at 6.5%: about $4,016 a month

Squeezing the loan into 8 years nearly doubles the monthly repayment

💡 The resale problem is the same problem, later

When Marama comes to sell, the next buyer faces an even shorter lease, perhaps only 3 or 4 years, and an even tighter loan, so the pool of buyers shrinks and the price falls. Short-term leasehold can suit a cash buyer with a clear plan, but for most people the financing and resale difficulty makes it very risky. If a lease is short, treat a low price as a warning, not a bargain, and get specific lending confirmation before you commit.

Loan to Value Ratio (LVR) Guide

New Build vs Existing Home

Aroha and Sam: $700k new build vs $750k existing

Aroha and Sam are choosing between a $700,000 new build and a $750,000 established home. To compare running costs fairly, assume both buy with a 20% deposit and a 6.0% illustrative interest rate.

  1. New build deposit: $700,000 × 20% = $140,000, so the loan is $560,000
  2. Existing home deposit: $750,000 × 20% = $150,000, so the loan is $600,000

The existing home needs $10,000 more deposit

Priya: a small deposit and the new-build exemption

Priya has saved $80,000 and is looking at a $600,000 property. She wants to know whether buying new makes her deposit stretch further.

  1. A 20% deposit would be $600,000 × 20% = $120,000
  2. Priya's deposit: $80,000 ÷ $600,000 = 13.3%

She needs the bank to lend above 80%, which it can only do for up to 25% of its new owner-occupier lending, so approval is not guaranteed

💡 Why the exemption matters

The same $80,000 deposit gives Priya a much clearer path to finance on a new build than on an existing home, because the new build sits outside both the LVR and DTI limits. If she is a first home buyer within the income caps, the First Home Loan strengthens that further.

The Nguyen family: turnkey vs build contract

The Nguyens can buy a $750,000 turnkey home, or buy a $350,000 section and build a $400,000 house under a build contract, for the same $750,000 end value. Assume a 6.0% illustrative rate and a 9-month build.

  1. Deposit on signing: $750,000 × 10% = $75,000
  2. Balance on completion: $675,000

No construction-period interest, they keep renting until handover

⚠️ Progress payments cost cash flow

The build contract exposes the Nguyens to roughly $24,750 of interest during the build, on top of any rent, before they even move in. The turnkey option defers that cost and locks the price, but gives them less control over the design. A build contract can still work out cheaper overall or give a better home, as long as they budget for the carrying cost and a contingency for variations.

Tama: the bright-line test applies to both

Tama has heard that new builds have a shorter bright-line period, and is weighing a new build against an existing home he might sell within a few years.

  1. For property sold on or after 1 July 2024, the bright-line test is 2 years for both new builds and existing homes
  2. If the property is his main home, the bright-line test generally does not apply at all

The old 5-year (new build) versus 10-year (existing) split no longer exists

💡 Bright-line is no longer a tie-breaker

Because the 2-year period is identical for new builds and existing homes, the bright-line test should not sway Tama's choice. Decide on price, finance, running costs and the home itself. If you may sell within 2 years, factor in the possible tax, and check the main-home exclusion with a tax adviser.
