What costs to allow for when buying a house in NZ
Extra costs to plan for around a house deposit.
Start with the deposit, then keep a separate cost bucket
A common mistake is treating the deposit as the whole cash requirement. In practice, buyers often need a second bucket for checks, reports, legal work, moving, and lender-related costs.
- Deposit funds: savings, KiwiSaver, gifts, sale proceeds, or other money you expect to use.
- Due-diligence costs: LIM, building inspection, specialist reports, title review, and sometimes valuation.
- Transaction costs: legal fees, loan fees, moving, utilities, cleaning, and other setup costs.
Example: If a buyer has $120,000 available and wants a 20% deposit on a $600,000 property, the deposit target uses the whole $120,000. A $5,000 buying-cost allowance would need to come from extra cash, a lower deposit target, or another verified source.
Due-diligence costs depend on the property and sale method
A deadline sale, tender, or auction can bring costs forward because buyers may need to check more before making an offer or bidding unconditionally.
- LIM and title review can help surface council, consent, hazard, rates, or ownership questions for professional review.
- Building inspection costs can vary by property size, urgency, access, and whether specialist checks are needed.
- Valuation may be requested by a lender or chosen by a buyer, but it should not be treated as a guaranteed purchase price.
Check next: Before spending money, check the sale method, offer deadline, finance timing, and which reports already exist. Reusing a vendor report without review can carry risk.
Moving and setup costs can be small individually but awkward together
The final week before settlement can be busy. Small line items can stack up at the same time as insurance, utility changes, movers, cleaning, storage, and final legal work.
- Allow for moving, temporary storage, cleaning, connection fees, locksmiths, urgent repairs, and time off work where relevant.
- Keep insurance timing visible, especially where lender approval or settlement depends on cover being in place.
- Leave room for quote changes rather than using the lowest possible estimate as the plan.
What to check next
Use a guide for context, then use calculators for the actual arithmetic.
- Use the buying costs calculator to total your own cost lines.
- Use the buyer workflow when deposit, costs, LVR, DTI, and repayments all need to connect.
- Check material figures with your lawyer, lender, insurer, adviser, council, or report provider before relying on them.
