Buying or Refinancing a Home: Approval Stages, Valuations, Documents and Costs

Whether you are buying your first home, upgrading to a larger property, or considering refinancing an existing loan, the preparation and process share more common ground than most people expect. Both paths depend on understanding your borrowing position, organising your documents early, and knowing what lenders look for before they make a decision. This guide, written by Mary Nebotakis, Managing Director of Natloans (B. Eco, Dip. Financial Services), walks through each stage clearly so you can move forward with confidence.

How the Home Buying Process Works

Most buyers begin with a rough budget in mind. The gap between that number and what a lender is actually willing to approve is often the first significant surprise.

Your borrowing capacity depends on a combination of factors: your income, existing debts, living expenses, and the size of your deposit. A broker can estimate this fairly quickly — sometimes without touching your credit file — so you have a real working number before you start attending inspections.

From there, the process follows a broadly consistent sequence regardless of where you live in Australia:

  1. Pre-approval — the lender reviews your financial position and indicates a lending ceiling, subject to conditions.
  2. Property search and offer — investigate the property and contract before committing. A pre-approval amount is conditional, not a confirmed final spending limit.
  3. Property valuation — the lender assesses acceptable security value using its valuation process, which may include automated, desktop or physical assessment depending on the lender and property.
  4. Conveyancing — engage your solicitor or conveyancer early to review the contract, title, conditions and legal risks before signing or bidding.
  5. Formal (unconditional) approval — the lender completes its full credit assessment and confirms it is ready to proceed.
  6. Settlement — ownership transfers and funds are paid on the contractual settlement date, subject to the transaction requirements. Do not calculate a new deadline automatically from the date of finance approval.

For first home buyers, there are additional considerations including government grants, stamp duty concessions, and scheme eligibility. Many of these programs have property price caps and income thresholds that affect which part of the market is realistically accessible, so it is worth checking what applies to your state and situation before setting your budget.

How Long Does Each Step Take?

As published by Natloans on 5 June 2026, the typical timeline is as follows:

Stage Typical Duration
Pre-approval A few business days to one week (depending on lender and paperwork completeness)
Formal approval after accepted offer One to two weeks
Settlement On the contracted date; the source’s four-to-six-week description is illustrative, not an automatic period after approval

These timelines can compress or extend at any point. A missing payslip or a complex property title can add days. The most reliable way to keep things moving is to have your documents ready from the start. (Source: Natloans, published 5 June 2026.

When Home Loan Refinancing Is Worth Exploring

Refinancing means replacing your existing home loan with a new one — either with your current lender or a different one. Whether it is worthwhile depends on whether the potential saving outweighs the costs and effort involved.

Rate Changes and Fixed-Period Endings

The source presents a lower-rate opportunity and the end of a fixed period as reasons to review. Check the actual contract’s reversion rate and options; do not assume it will always be a standard variable rate or that it must be higher. The source gives no data establishing the most common refinancing reason.

Costs to account for when refinancing include:

The source gives six months to two years as an indicative break-even range, but supplies no evidence that this applies to most borrowers. Your result depends on actual costs, balance, rates, term, fees and how long you keep the loan. There may be no worthwhile break-even point. Obtain a calculation for your situation.

Equity Access and Debt Consolidation

If your property has increased in value, refinancing can also be a way to access that equity. The lender orders a new valuation, and the amount you can access depends on your loan-to-value ratio (LVR) and current income.

Some borrowers refinance to consolidate other debts into the home loan. It is important to understand that while monthly repayments can fall, the term of the debt usually extends, and total interest paid over the life of the loan can be higher. Running the numbers carefully before proceeding is essential. A broker can help you do that.

For more context on why borrowers are considering this option, see Natloans' article on why so many Australians are refinancing.

When To Get Pre-Approval and When To Wait

Pre-approval is a conditional commitment from a lender. They have reviewed your financial position and indicated how much they are prepared to lend — but it remains subject to the property checking out and your circumstances not changing before the full application is assessed.

Pre-approval can help frame a search budget, but it does not remove auction finance risk. Check the lender’s remaining conditions and property acceptance before bidding and obtain contract advice. Private-sale finance conditions must be agreed in the contract; pre-approval itself creates no right to exit.

It is less useful if you are six or more months from buying, since pre-approval may expire before you need it. Most approvals last 90 days; some lenders extend to six months. Applying to several lenders over a short window can also leave multiple credit enquiries on your file, which may affect future applications.

What Happens During a Property Valuation

A lender uses its valuation process to assess the property as security. Comparable sales, property characteristics and the relevant method can produce a figure different from the price agreed by buyer and seller. Not every loan requires a physical inspection by an independent valuer; ask how the particular assessment will be completed.

The original example assumes a $780,000 auction purchase and a $750,000 lender valuation. A lower valuation can reduce the available loan. It does not give a buyer an automatic right to renegotiate or withdraw from an auction contract. Any alternative funding or agreed contract change requires timely discussion with the lender and legal adviser; failing to settle can have serious consequences.

The valuation result also feeds directly into your LVR. A lower assessed value means a higher LVR, which can trigger Lenders Mortgage Insurance (LMI) if you are borrowing above 80 per cent of the assessed value.

The source claims most valuations are close to purchase price but supplies no supporting dataset. Plan for a possible valuation shortfall rather than treating that statement as a probability or guarantee.

Getting Your Documents Ready

Paperwork is the part most applicants underestimate. Having the right documents ready before you apply reduces delays and makes the first conversation with a broker or lender more productive.

The full list depends on your lender and circumstances, but most applications call for:

The source describes two years of tax returns and ATO notices of assessment as a common self-employed document set. Requirements vary: some conventional lenders accept one year or other eligible evidence, while alternative-documentation products have separate criteria. Shorter trading history is not itself a guarantee of low-doc eligibility. Compare the actual documentation, rate, fees and security requirements.

If you are refinancing rather than buying, add your most recent mortgage statements and a recent council rates notice to the list.

You do not need everything perfect before speaking to a broker. But getting the basics together at the start means less back-and-forth once the application is underway.

State-Specific Considerations

Buyers in Sydney, Melbourne, Brisbane, Darwin, Hobart, Adelaide, and Perth follow the same broad process when buying or refinancing. However, local property conditions, competitive pressure, and some grant eligibility differ by state.

Buying in Adelaide as a First Home Buyer or Upgrader

Eligible Adelaide buyers may qualify for South Australian grants or duty relief and separate national home-buyer initiatives. They are not all federal grants, and price or income caps are not universal. RevenueSA, checked 15 October 2026, states that eligible new-home buyers can receive up to $15,000 FHOG, with no property-value cap for contracts from 6 June 2024. For eligible new homes or vacant land under contracts from that date, its first-home duty relief also removes duty. Eligibility, ownership history and residence requirements still apply; this is not an entitlement for every first purchase or an established home.

Upgraders may need to compare selling first, buying first, bridging finance and usable equity. Speak with a broker before listing or making an offer to develop a better-informed estimate and identify the lender assessment still needed. The source offers a free consultation with the Natloans Adelaide team; this is not a final approved borrowing amount or proof of a staffed local office.

Buying in Perth With Variable or Self-Employed Income

The source discusses Perth contract, FIFO and shift-based employment and attributes its prevalence to the resources sector. No comparative workforce dataset is supplied to verify a higher share than other capitals. Lenders may treat variable income differently from base salary, with evidence requirements determined by the actual lender.

Shift allowances and overtime may be discounted or require a two-year history before a lender counts them in full. Contract income often needs a track record of renewals. Self-employed applicants face additional documentation requirements regardless of industry. Understanding which lenders take a more flexible view of variable income — and having your paperwork organised before you apply — can make a real difference to how smoothly an application moves. The Natloans Perth team works with buyers across all income structures.

Frequently Asked Questions

How long is pre-approval valid for?

Most lenders issue pre-approval for 90 days. Some extend to six months. If your pre-approval expires before you have found a property, you can usually reapply — but your financial details will be reassessed, and any changes to your income or debts since the original application may affect the outcome. (Source: Natloans, published 5 June 2026. Confirm current lender policies with Natloans.)

Can I refinance while I am still on a fixed-rate loan?

Yes, but there are usually break costs involved. As published by Natloans on 5 June 2026, these costs are calculated based on how much of your fixed term remains and the difference between your rate and current wholesale rates. In some cases break costs make switching uneconomical mid-term; in others — particularly where rates have moved significantly — it can still make sense. A broker can run that calculation before you commit. (Source: Natloans, published 5 June 2026.)

What is the difference between conditional and unconditional approval?

Conditional approval indicates lender willingness subject to stated requirements, which can include further verification and acceptable property security. Formal or unconditional credit approval means the credit assessment conditions have been satisfied as specified by the lender; loan documents, insurance, security and other settlement requirements may still remain. Read the actual approval and contract rather than treating the label as completed settlement.

Do I need a 20 per cent deposit to buy a home?

No. Some lenders will approve loans with a deposit as low as five per cent, though borrowing above 80 per cent of the assessed value usually triggers Lenders Mortgage Insurance (LMI). There are also government schemes that allow eligible first home buyers to purchase with a smaller deposit without paying LMI. A broker can explain which options apply to your situation. Confirm current scheme eligibility and thresholds with Natloans, as these can change.

What costs should I account for when refinancing?

The main costs include discharge fees from your existing lender, application and settlement fees on the new loan, and break costs if you are exiting a fixed rate early. The break-even point — when savings from a lower rate offset the switching costs — varies depending on loan size and the rate difference. A broker can model this for your specific situation before you commit.

How does a broker estimate my borrowing capacity?

A broker looks at your income, existing debts, living expenses, and deposit to form an estimate. In many cases this can be done without a formal credit enquiry, so your credit file is not affected at the preliminary stage. This gives you a realistic working number before you begin inspecting properties or approaching lenders directly.

What is Lenders Mortgage Insurance (LMI)?

LMI protects the lender, not the borrower, if a covered default causes a loss. It may be required when the loan exceeds a lender’s permitted LVR, often above 80%, but the threshold, waivers and government-scheme exceptions vary. Where allowed, adding the premium to the loan increases the balance and interest cost. Confirm the exact premium and treatment rather than assuming LMI always applies above 80%.

What additional documents do self-employed applicants need?

The source suggests two years of tax returns and ATO notices, but this is not universal. See the self-employed guide for document categories and a current lender example. Conventional one-year evidence and alternative-documentation options are subject to distinct policies, sustainable income and full assessment.

Does a property valuation always match the purchase price?

No. The lender’s accepted value can differ from purchase price, and the available loan depends on that value and the approved LVR. The source’s claim that most values match is unverified. A shortfall does not automatically release a buyer from a signed contract or winning auction bid; obtain legal advice before committing and urgently if funding falls short.

How does refinancing to consolidate debt work?

Debt consolidation can combine other debts with mortgage borrowing. It can reduce monthly payments through a different rate or term, but extending repayment may increase total interest. A term extension is not compulsory or always appropriate. Compare each debt’s remaining term and cost and consider that formerly unsecured debt may become secured against the home.

When should I speak to a broker — before or after finding a property?

Before. Speaking to a broker before you begin searching means you understand your borrowing capacity, have a realistic budget, and can move quickly when you find the right property. At auction in particular, you need to know your limit before you bid, because the purchase is unconditional. For refinancing, speaking to a broker before you approach a new lender means you can compare options across multiple lenders rather than accepting the first offer you receive.

Next Steps

Whether buying or refinancing, establish your borrowing position before committing. The June 2026 source says Natloans compares options across 50-plus lenders at no cost to the borrower. Treat that as its published service claim, confirm the current panel and credit-guide fee disclosures, and distinguish the broker’s consultation or comparison service from lender, legal, government and other transaction costs.

What the valuation example means in dollars

Using the source’s $780,000 price and $750,000 valuation, suppose the lender permits an 80% LVR and nothing else changes. The expected loan at 80% of price would be $624,000; 80% of the lower valuation is $600,000. The resulting funding gap is $24,000, not automatically the full $30,000 difference in values. Cash toward price rises from $156,000 to $180,000, before transaction costs. This is an editorial calculation, not a loan offer; a different approved LVR, borrowing capacity or fee treatment changes the result.

Important limits on the source’s timeframes and examples

The published guide quotes a few business days to one week for pre-approval, one to two weeks for formal approval, and pre-approval validity commonly described as 90 days or up to six months. These are source estimates, not universal lender policies, promised service levels or extensions of a purchase contract. Obtain the actual expiry, conditions and settlement deadline. Asking a broker for an estimate can sometimes avoid a credit enquiry, but confirm what consent and enquiry the proposed step involves.

Consumer Affairs Victoria’s auction guidance, checked 15 October 2026, warns that auction purchases do not have cooling-off rights and finance conditions require the seller’s agreement. Its rules are Victorian; buyers elsewhere must check the relevant state rules. Do not rely on the original article’s suggestion that a low valuation simply lets an auction buyer reconsider the purchase.

ASIC Moneysmart’s refinancing guidance supports comparing existing-lender repricing, fees and remaining term. Include relevant valuation, LMI and other costs as well as the three cost categories in the source. A new loan or equity withdrawal still needs approval. See the current first-home scheme guide for distinctions between grants, duty relief, guarantees and shared equity.
