Get Your Mortgage Pre-Approval Before You Start House Hunting

Mortgage Pre-Approval

Know your price range before you fall in love with a house.

Mortgage pre-approval gives you a conditional lending amount before you have found a property. It helps you understand what a lender may be prepared to lend, what conditions still need to be met, and what price range may be realistic before you start making offers.

The basics

What Is Mortgage Pre-Approval?

Mortgage pre-approval is a conditional approval from a lender showing the amount they may be prepared to lend, subject to conditions.

The lender reviews your financial position before you have chosen a property. This usually includes your income, expenses, debts, deposit, credit history, account conduct, and where your deposit has come from.

If the lender is comfortable with the application, you will receive an approved lending amount, an expiry date, and a list of conditions that still need to be met.

Pre-approval is useful because it gives you a clearer price range before you start looking seriously or making offers.

It is not final approval. The lender still needs to accept the property and confirm that all conditions have been met before the loan can proceed.

Why it matters

What Does Pre-Approval Let Me Do?

Pre-approval helps you understand what a lender may be prepared to lend before you make an offer on a home.

It can help you:

  • Shop within a clearer price range
  • Understand your deposit position and any conditions
  • Identify potential issues before you make an offer
  • Show agents and sellers that your finance has been assessed
  • Move more confidently when the right property comes up

Pre-approval can also highlight issues early.

Things like a high credit limit, short employment history, unexplained deposit, gifted funds, or account conduct questions are easier to deal with before you are inside a finance condition period.

The goal is to know where you stand before the pressure of a property deadline.

Your real buying number

How Much Can I Offer With Pre-Approval?

The amount on your pre-approval letter is the loan amount, not the total amount you can spend.

Your practical buying number depends on your approved lending, the deposit you can actually use, and the cash you need to keep aside for other costs.

Those costs may include:

  • Lawyer or conveyancer fees
  • Building inspection
  • Registered valuation, if the lender asks for one
  • LIM or council records
  • Moving costs
  • Urgent repairs or setup costs
  • Any low-equity fee, premium, or margin that applies
  • A cash buffer after settlement

Your approval letter may also include a maximum purchase price, minimum deposit requirement, or property conditions.

We help check the loan amount, deposit, price limit, and lender conditions before you make an offer.

Use our borrowing power calculator for an early estimate. Formal pre-approval is where a lender assesses the real application.

Example One: A 20% Deposit
Approved lending$640,000
Cash available$185,000
Set aside for costs and buffer- $12,000
Deposit you can use$173,000
Estimated working purchase limit$813,000

At this purchase price, the loan would be around 79% of the property value.

That means the application is below 80% LVR, which may give access to a wider range of lender options than a low-deposit application, subject to lender criteria.

Example Two: A 10% Deposit
Approved lending$630,000
Cash available$85,000
Set aside for costs and buffer- $12,000
Deposit you can use$73,000
Estimated working purchase limit$703,000

At this purchase price, the loan would be around 90% of the property value.

That is low-deposit lending. It may involve stricter lender criteria, fewer lender options, and low-equity costs such as a low equity margin or premium.

That does not mean it cannot work. It means the application needs to be matched carefully with lender policy before it is submitted.

Behind the decision

What Will The Bank Check?

A lender is usually trying to answer two main questions: can you afford the loan, and does the application fit the lender's policy?

To assess this, the lender may look at:

  • Salary, wages, business income, and any other income it will accept
  • Employment history and whether you are on a trial period
  • Your deposit and where each part has come from
  • KiwiSaver, savings, gifts, or existing equity being used
  • Credit cards, overdrafts, buy-now-pay-later accounts, car loans, and student loan deductions
  • Household spending and dependants
  • Account conduct, including missed payments, unarranged overdrafts, and gambling patterns
  • The type of property you want to buy
  • Whether the property will be owner-occupied or an investment

Banks do not assess affordability only at the rate you may pay on settlement day. They usually test the loan at a higher servicing rate to check whether repayments would still be manageable if rates changed.

This is one reason a lender's approved amount can be lower than an online calculator estimate.

Reserve Bank rules also sit alongside lender affordability policy.

Owner-occupier lending above six times gross annual income is treated as high-DTI lending. Banks are limited in how much high-DTI lending they can write, and they still apply their own affordability rules.

Deposit rules also matter. Banks can do some owner-occupier lending above 80% LVR, but low-deposit lending is limited, and each lender applies its own criteria.

Get your pack ready

Which Documents Do I Need For Pre-Approval?

A complete document pack can help reduce delays.

The exact documents depend on the lender, your income type, your deposit source, and the type of property you want to buy.

Most applicants should be ready with:

  • Current photo identification
  • Proof of address, if requested
  • Recent payslips or employment contract
  • Bank statements for everyday, savings, and debt accounts
  • Evidence of your deposit and where each part came from
  • Current balances and limits for credit cards, overdrafts, and loans
  • Details of any KiwiSaver funds intended for the purchase
  • Evidence for board, rent, bonuses, commission, or other income being used

If you are self-employed, the lender may ask for financial statements, tax returns, recent accounts, and business bank statements.

Some lenders may consider shorter trading periods or more recent management accounts, depending on the business, income history, and reason for the application.

We check the documents before the application is submitted.

If there is an unusual transfer, one-off expense, gifted deposit, or income detail that needs explaining, it is usually better to deal with it upfront rather than waiting for the lender to ask later.

Timing

How Long Will My Pre-Approval Take And Last?

Timing depends on the lender, the strength of the application, and how complete the documents are.

A straightforward application may be assessed within a few working days.

Applications can take longer if there is missing information, self-employed income, low deposit lending, unusual property plans, gifted funds, or busy lender queues.

We can let you know the current lender timeframe before submitting the application.

Pre-approval commonly lasts for up to three months, but the exact expiry date will be shown on your approval letter.

If you are still searching near expiry, the lender may need to reassess the file. This may include updated payslips, bank statements, a new credit check, or assessment under current lender policy and servicing rates.

An extension is not automatic.

Auctions

Can I Bid At Auction With Mortgage Pre-Approval?

Pre-approval alone is usually not enough for an auction.

An auction purchase is normally unconditional. This means you cannot add a finance condition after winning the bid.

Before auction day, the lender needs to assess the specific property and confirm whether it is acceptable as security.

The lender may need the property address, sale and purchase agreement, title, insurance confirmation, registered valuation, or other property documents.

Your lawyer should also review the auction terms, title, and property documents before you bid. Building inspections and other due diligence should be completed before auction day.

Your maximum bid should take into account:

  • The price the lender is prepared to accept for that property
  • The purchase price your deposit can support
  • The repayment level you are comfortable with
  • The cash buffer you want to keep after settlement

We help check the finance side before auction day, but your lawyer confirms the legal position and auction risk.

What can change

Could My Pre-Approval Still Fall Over?

Yes. Pre-approval is conditional.

The lender can revisit the application before final approval or settlement if something changes or if a condition is not met.

Your approval may be affected if:

  • The property has an issue with title, condition, location, valuation, or insurability
  • The valuation does not meet the lender's requirement
  • Your income, job, hours, or employment terms change
  • You take out a new loan, credit card, overdraft, or buy-now-pay-later account
  • Your deposit changes or its source cannot be verified
  • New spending or dependants reduce your repayment surplus
  • A payment is missed or new credit information appears
  • The approval expires
  • Lender policy or servicing rates change before you buy

Tell us before taking on new credit, changing jobs, reducing hours, or using deposit funds.

Even a credit card with a zero balance may affect borrowing because many lenders assess the credit limit as available debt.

Once you find a property, the lender must confirm the loan before a conditional offer goes unconditional. Your lawyer should confirm when the sale and purchase agreement becomes binding.

One application, the right lender

Should I Apply To Several Lenders At Once?

It is usually better to compare lender policy first, then submit a clear application to the lender that appears to fit best.

Repeated credit applications over a short period may also affect how your credit file looks to lenders.

We compare lender policy before submitting. This includes deposit rules, accepted income, servicing, turnaround time, property type, and the kind of loan you are applying for.

Once we understand the position, we prepare one clear application.

If that lender declines or adds a condition that makes the loan unworkable, we can reassess the next step using the same core documents.

Timing it right

When Is Pre-Approval Not The Right First Step For Me?

Sometimes an early assessment is more useful than submitting a formal pre-approval application straight away.

Pre-approval may be too early if you are still many months away from buying, your deposit is not ready, your income is about to change, or you are not yet sure what type of property you want.

Pre-approvals usually expire, so applying too early can mean needing to reassess the file later anyway.

In that case, we can start with an early assessment. This can help you understand a working price range, what documents may be needed, and what steps may improve the application before formal pre-approval.

It may also be better to pause before applying if:

  • Your account conduct needs a cleaner period first
  • Your tax returns or business accounts are overdue
  • You need to reduce debt to reach the borrowing amount you want
  • Your deposit includes a gift or family loan that has not been documented
  • You are planning a job change before purchasing
  • The property is already under contract and needs a full property-specific decision now

The goal is to submit the application at the right time, with the right lender, and with the strongest information available.

    We compare your application against current bank and non-bank lender policy. This helps identify which lender may be the best fit before anything is submitted.

  4. Prepare The Application

    We package the documents, explain anything unusual, and deal with lender questions. Nothing is submitted to a lender without your approval.

  5. Read Every Condition With You

    If pre-approval is issued, we help you understand the approval letter. This includes the approved lending amount, deposit needed, price limit, expiry date, property requirements, and any conditions still to be met.

  6. Move From Pre-Approval To Final Approval

    When you find a property, we send the property details to the lender and help work through the remaining finance conditions. Your lawyer handles the contract and confirms when it is safe to go unconditional.

Mortgage Pre-Approval FAQs

Your Questions Answered

Have more questions?

Get My Pre-Approval

Is Pre-Approval The Same As Final Home Loan Approval?

No. Pre-approval is conditional approval based on your financial position up to a stated amount.

Final approval comes after the lender accepts the property, confirms the remaining conditions, and issues final loan documents.

Is Pre-Approval Guaranteed?

No. Pre-approval is conditional.

The lender can decline the property or reassess the application if your circumstances, credit information, deposit, lender policy, or the property details change.

Always read the expiry date and every condition on the approval letter.

How Long Does Mortgage Pre-Approval Last?

Pre-approval commonly lasts for up to three months, but the exact period depends on the lender and will be shown on the approval letter.

A renewal may require updated payslips, bank statements, a new credit check, and reassessment under current lender rules.

Does Pre-Approval Affect My Credit Score?

Potentially. A lender may record a credit enquiry when assessing the application.

One well-prepared application is different from sending repeated applications to several lenders in a short period.

We compare lender fit before applying to help avoid unnecessary applications.

How Much Deposit Do I Need For Pre-Approval?

It depends on the lender, your income, property type, deposit source, and overall application.

Many lenders prefer at least a 20% deposit, but some low-deposit options may be available for eligible borrowers.

A smaller deposit may mean stricter lender criteria, low-equity costs, and fewer lender options.

See our low deposit home loan guide for more detail.

Can I Get Pre-Approval Before Choosing A House?

Yes. That is the purpose of pre-approval.

The lender assesses your financial position first, then checks the property details when you find a home.

The property still needs to be acceptable to the lender before final approval.

Can I Make An Offer Subject To Finance?

Yes, if the seller accepts that condition.

Your lawyer should write or check the finance clause and confirm the timeframe needed for the lender to approve the property.

A generic finance clause may not protect you in every situation, so legal advice is important before signing.

Does Pre-Approval Let Me Bid At Auction?

Not by itself.

Before bidding at auction, the lender should be given the property details and asked to confirm whether the property is acceptable.

Your lawyer and building inspector should complete their checks before auction day, because the winning bid is usually unconditional.

Does Pre-Approval Lock In My Interest Rate?

Usually no.

Pre-approval normally confirms the conditional lending amount, not the final interest rate or full loan structure.

The available rate is usually confirmed closer to settlement, subject to lender rules and any rate-lock options available at the time.

Can I Get Pre-Approval If I'm Self-Employed?

Yes. Self-employed borrowers can apply for pre-approval.

Most lenders will want financial statements, tax returns, and recent business information. Some lenders may consider a shorter trading history or more recent accounts, depending on the business and the reason behind the figures.

Can I Use Pre-Approval From One Bank At Another?

No. A pre-approval belongs to the lender that issued it.

You can apply with another lender, but that lender will complete its own assessment and may approve a different amount, add different conditions, or decline the application.

Does It Cost To Use A Mortgage Adviser?

There is no adviser fee payable by you for our mortgage advice service.

If your loan settles, we are paid by the lender you choose. This does not get added to your loan as a separate adviser fee.

How we are paid, including any lender commissions, is explained clearly in our Disclosure Statement.

In most cases our advice costs you nothing. We're paid by the lender you choose. In a small number of situations a fee applies, and we'll always tell you before any work starts. We're paid much the same whichever lender you go with, so the recommendation is about the loan, not the commission.
