๐Ÿ  First Home Buyer Guide - New Zealand

Buying your first home in New Zealand involves understanding deposits, LVR ratios, KiwiSaver HomeStart grants, borrowing capacity, and the complete purchase process. This guide walks you through every step from saving to settlement, with real NZ examples and costs.

Key Point: First home buyers need a 20% deposit to avoid Lenders Mortgage Insurance (LMI), but can borrow with as little as 10% deposit (5% for new builds). KiwiSaver HomeStart grants provide up to $10,000 per person ($20,000 for couples) and you can withdraw KiwiSaver funds. Total costs include deposit, legal fees ($1,500-$3,000), building reports ($500-$800), LIM ($300), moving costs, and initial setup. Budget $5,000-$10,000 on top of deposit.

The Complete Cost Breakdown

Example: Purchasing a $650,000 home

Cost Item Amount Notes
Purchase price $650,000 Agreed sale price
Deposit (20%) $130,000 Your savings + KiwiSaver
Mortgage amount $520,000 What you borrow
Legal/conveyancing $2,000 Lawyer fees
Building report $650 Pre-purchase inspection
LIM report $300 Council property info
Valuation $800 Bank requirement
Moving costs $1,500 Truck/movers
Initial setup $3,000 Appliances, furniture
Total cash needed $138,250 Deposit + costs

Deposit Requirements

Standard Deposit (Existing Homes):

Minimum 10% deposit (Low Equity Loan - LMI applies)
Recommended 20% deposit (No LMI, better rates)
Example: $600K home needs $120K for 20% deposit

New Build Deposit:

Minimum 5% deposit for new builds
Government supports new build lending
Example: $700K new build needs $35K for 5%

Loan to Value Ratio (LVR)

LVR is the percentage you borrow vs property value:

LVR = Loan Amount รท Property Value ร— 100
Example: Borrow $480K on $600K home
LVR = $480,000 รท $600,000 ร— 100 = 80%
20% deposit = 80% LVR
LVR Level Deposit Implications
80% LVR 20% Standard lending, best rates, no LMI
85% LVR 15% Low equity, LMI applies (+0.5-0.75% rate)
90% LVR 10% Low equity, higher LMI (+0.75-1.00%)
95% LVR 5% New builds only, high LMI
โš ๏ธ Lenders Mortgage Insurance (LMI)

LVR over 80% = LMI applies
LMI protects the bank (not you) if you default. Adds 0.5-1.0% to your interest rate annually until LVR drops below 80%. On $500K loan, LMI costs extra $2,500-$5,000/year. Pay down to 80% LVR quickly to remove LMI premium.

KiwiSaver HomeStart Grant

Government grant for first home buyers (not a loan, doesn't need repayment):

Grant Amounts:

Years in KiwiSaver Existing Home New Build
3 years $1,000 per person $2,000 per person
4 years $2,000 per person $4,000 per person
5+ years $5,000 per person $10,000 per person

Couple scenario: Both in KiwiSaver 5+ years buying new build = $20,000 grant!

Eligibility Requirements:

  • Been in KiwiSaver 3+ years
  • Contributed at minimum required rates
  • First home purchase (or similar to first home buyer)
  • Will live in the property
  • Income under cap (singles $95K, couples $150K in Auckland; lower outside Auckland)
  • Purchase price under cap ($700K Auckland, $600K elsewhere for existing; $875K Auckland, $750K elsewhere for new builds)

KiwiSaver Withdrawal

Can withdraw KiwiSaver savings (not employer/government contributions) for first home:

Must leave $1,000 in KiwiSaver account
Can withdraw all member contributions + returns
Example: $45,000 in KiwiSaver, withdraw $44,000
Plus HomeStart grant = significant deposit boost

Borrowing Capacity

How much can you borrow? Banks assess:

Income Assessment:

Combined household income
Job stability (probation periods matter)
Other income sources (rental, side business)

Debt-to-Income (DTI) Ratio:

Total debt รท Annual income < 6x (NZ guidance)
Example: $100K income โ†’ max $600K total debt
Includes car loans, student loans, credit cards

Servicing Calculation:

Banks stress-test at higher rates:

Current rate: 6.5%
Test rate: 8.5-9.0% (stress test)
Must afford repayments at test rate
Ensures buffer if rates rise

Ongoing Property Costs

Budget for these annual costs:

Cost Annual Amount Notes
Mortgage repayments $35,000+ Depends on loan size
Rates (council tax) $2,500-$4,500 Varies by location
Insurance $1,200-$2,000 House + contents
Maintenance $3,000-$6,000 1% of property value/year
Body corp (if applicable) $2,000-$8,000 Apartments/townhouses

The Purchase Process

Step 1: Get Pre-Approved (4-6 weeks before house hunting)

  • Approach multiple banks for pre-approval
  • Provide income proof, deposit evidence, ID
  • Get approved amount in writing
  • Pre-approval typically lasts 90 days

Step 2: Find Your Property (2-6 months)

  • Attend open homes
  • Research suburb prices, schools, transport
  • Check property history (homes.co.nz, QV)
  • Don't rush - average search takes 3-4 months

Step 3: Make an Offer (1-2 weeks)

  • Submit offer through agent or directly
  • Include conditions: finance, building report, LIM
  • Typical condition period: 10-15 working days
  • Negotiate price and terms

Step 4: Due Diligence (10-15 days)

  • Order LIM from council ($300, 10 working days)
  • Book building inspection ($500-$800)
  • Confirm finance with bank
  • Review all reports carefully
  • Renegotiate or withdraw if issues found

Step 5: Go Unconditional (Day 1 after conditions met)

  • Remove all conditions once satisfied
  • Pay deposit (usually 10% of purchase price)
  • Deposit held in trust until settlement
  • Sale becomes binding

Step 6: Settlement (20-30 days after unconditional)

  • Bank pays balance to vendor's lawyer
  • You pay remaining costs to your lawyer
  • Keys collected on settlement day
  • Property officially yours!

Stretched Budget - Learned Hard Way

Mike & Sarah, maxed out borrowing capacity

The Mistake:

Combined income: $120,000
Bank approved: $650,000 loan
Purchased: $800,000 home (max budget)
Monthly mortgage: $4,108
Left no buffer for costs

What Happened:

  • Hot water cylinder failed: $2,500
  • Roof leak: $4,000
  • Rates bill: $3,800/year (didn't budget)
  • Had to use credit cards
  • Financially stressed within 6 months

The Lesson:

Don't borrow maximum approved amount. Leave 15-20% buffer for unexpected costs and rate increases. Better to buy below budget than stretch too far.
