Home loan or personal loan: which is right for you?

Compare total interest, fees and repayment terms, then check whether the loan and deposit source fit your purchase.

A home loan often has a lower rate than a personal loan, but the repayment term can outweigh that advantage. Compare the total interest, fees and security risk over the time you actually intend to repay the debt.

For a first home buyer, there is another question: will the mortgage lender accept borrowed deposit funds? A new personal loan also adds a repayment commitment, which can reduce the mortgage you qualify for.

Home loan vs personal loan

How home loans and personal loans work in Australia

Both home loans and personal loans are regulated under Australia's National Consumer Credit Protection Act, meaning lenders must comply with ASIC's responsible lending rules. However, they function very differently.

  • A home loan uses property as security. The lender assesses your income, expenses, deposit or equity, debts, credit history and the property.

    Deposit requirements and LMI depend on the lender and any eligible exemption or guarantee scheme. A longer mortgage term lowers the monthly repayment but usually increases total interest if you pay only the minimum.

  • Personal loans usually fund smaller expenses such as cars, renovations or debt consolidation. Many are unsecured; some use an asset such as a vehicle as security. Compare the rate, fees and term, often 1 to 7 years, and check affordability rather than assuming a quick approval.

Use cases: when people choose each loan

When a personal loan makes sense

When a personal loan makes sense

A personal loan may suit a smaller expense you plan to repay over a short period. Compare actual offers and your repayment budget.

  • Smaller renovations: an unsecured personal loan may avoid a property valuation, but its rate and fees can be higher. Compare the total cost with a short repayment schedule on any mortgage borrowing.
  • Urgent expenses: some personal lenders offer quick decisions, but funding depends on assessment and documents. Do not assume an unsecured loan can replace a property bridging facility.
  • Debt consolidation. Sometimes borrowers roll high-interest debts (credit cards, short-term finance) into a single personal loan with a fixed lower rate. If you prefer not to disturb your mortgage or lack equity, a personal loan for consolidation might be considered.
  • Early repayments. Check the loan terms: extra repayments or an early payout may be allowed, but fees or limits can apply, particularly to fixed-rate loans. Variable home loans can also allow extra repayments.

When a home loan is the better choice

When a home loan is the better choice

A mortgage is the usual finance for buying a home. For other expenses, compare the amount, repayment term and risk to your property before using home equity.

  • Buying a house. A mortgage is the usual loan for a home purchase. Check permitted uses before relying on a personal loan for any purchase funds. The 5% Deposit Scheme needs a participating lender; stamp duty concessions have separate eligibility rules.
  • Renovations: equity borrowing may have a lower rate, but it secures the extra debt against your home. Compare fees and repay the renovation portion over a suitable shorter period.
  • Buying a car: a $40,000 car added to a 30-year mortgage can remain a debt long after the car is gone. If using equity, compare a separate split repaid over 3 to 5 years with a personal or car loan, including fees and security risk.
  • Larger amounts: compare the lender's amount limits and security requirements. A mortgage may support more borrowing when equity and income allow it, but it is not automatically the only option.
  • Repayments: a lower rate and longer term can reduce the monthly amount. Check total interest over the proposed term, not just the payment.

The "30-year trap": why lower rates can cost you more

Be careful of the 30 year trap

When comparing financing options, most borrowers naturally look at the interest rate first. It seems logical: a home loan rate looks much cheaper than a personal loan.

Compare the repayment term as well as the rate.

A long mortgage schedule can cost more overall than a shorter personal loan, even at a lower rate. The example below holds the amount constant and excludes fees.

The numbers: personal loan and mortgage top-up

For illustration, both options fund a $30,000 kitchen renovation, with monthly principal-and-interest repayments and unchanged rates.

  • Option A (Personal Loan):You take a 5-year unsecured loan at 12%. Repayments are about $667 a month and total interest is about $10,000.
  • Option B (Mortgage Top-Up):You add the $30k to your home loan at 6% , but pay it off over the remaining 30-year term.


In option B, choosing the "cheaper" interest rate actually costs you  more in the long run. Repayments are only about $180 a month, but you pay about $34,800 in interest, so the $30,000 kitchen costs you more than twice its price.

The solution: how to beat the trap

A shorter repayment schedule can reduce the cost of equity borrowing. Check that the payment is affordable and the loan allows it.

If you choose to top up your mortgage, you should treat that specific portion of debt as if it were a short-term loan:

  • Create a Loan Split: Ask your broker to split your mortgage so the $30,000 is in a separate sub-account.
  • Increase Repayments:Calculate what the repayment would be on a 5-year term (about $580 a month at 6%, or about $4,800 in total interest).
  • Compare the 5-year mortgage schedule with the personal loan after setup fees. The home remains security for the mortgage borrowing.

Can I use a personal loan for a house deposit?

personal loan as house deposit

Some lenders may accept borrowed purchase funds in particular circumstances, but a personal loan is not genuine savings and its repayments affect affordability. Check lender policy before taking it out.

The "genuine savings" rule

Genuine-savings requirements vary. Some low-deposit loans require a savings history, often 3 months, while others accept different evidence or have exceptions. Ask what your proposed lender needs.

Crucially, a personal loan does not count toward this 5%.

A lender checks the source of your deposit. Having borrowed cash in a bank account does not turn it into genuine savings.

Why lenders are cautious

Lenders assess your overall financial risk when you apply for a mortgage. If your deposit is funded by another loan:

  1. Deposit policy: the lender may not accept borrowed funds or may require other evidence of your contribution.
  2. Reduced borrowing power: The lender counts the personal-loan repayment when assessing the mortgage. Ask for the effect on your application before taking on new debt.

What are your options?

If you are struggling to save that final 5% genuine deposit, a personal loan is rarely the answer. Instead, consider:

  • Government schemes: The Australian Government 5% Deposit Scheme allows eligible buyers to purchase with a 5% deposit without paying LMI, though you still typically need to show that 5% is your own money.
  • A guarantor may reduce the deposit needed, subject to lender requirements. It does not remove all savings or affordability checks, and the guarantor's security can be at risk.

Check to see if you are eligible for a home loan

Risks of using a personal loan for property expenses

A personal loan adds a repayment commitment. Check the effect on the proposed mortgage before using one for buying costs or a deposit.

  • Impact on borrowing power: Any personal loan you take out adds to your monthly committed expenses. When a mortgage lender assesses your application, they treat this repayment as a major liability.
    • There is no fixed multiplier. The effect depends on the personal-loan repayment, remaining term, lender assessment and the rest of your finances.
    • A $20,000 car loan can affect mortgage borrowing by more than its balance, but the result needs to be calculated using the actual repayment and lender requirements.
  • Interest rate and total cost: Compare both the rate and repayment term. At 12% over 5 years, a $10,000 personal loan costs about $222 a month and around $3,350 in interest. Added to a 30-year mortgage at 6%, the same $10,000 costs about $60 a month, but around $11,600 in interest if you only make the minimum repayments.
  • Borrowed deposits: a lender may reject them, exclude them from qualifying savings or reduce the available mortgage because of the extra repayments. Confirm the policy before borrowing.
  • LMI and costs: a personal loan does not itself provide an LMI exemption. Check the mortgage LVR and any scheme eligibility, then add both loans' fees.
  • Risk of Default: Juggling a high-interest personal loan alongside a new mortgage increases your risk of "mortgage stress." The shorter term of the personal loan means high monthly commitments that can become unmanageable if interest rates rise or your income drops.

Illustration 1: using saved deposit funds

which is better personal loan or home loan

An eligible buyer purchasing a $500,000 home could use $50,000 of savings as a 10% deposit, leaving a $450,000 mortgage before costs. If they qualify for a government guarantee or another exemption, LMI may be avoided. Keep separate cash for buying costs.

At an illustrative 6% over 30 years, monthly principal-and-interest repayments on $450,000 are about $2,698. If the rate never changed, total repayments would be about $971,272, including about $521,272 interest. Fees are excluded.

Illustration 2: borrowing the deposit

case study personal loan

Now assume the same $50,000 deposit is a personal loan at 12% over 5 years. Its repayment is about $1,112 a month. This does not establish that a mortgage lender would accept it; the lender could:

  • (a) rejects his mortgage, or 
  • (b) approves only up to a smaller loan. 

If a lender accepted the borrowed deposit and approved the same $450,000 mortgage at 6% over 30 years, the combined repayment would be about $3,810 a month. That is about $1,112 more than the saved-deposit example for the first 5 years, before fees or LMI.

The personal loan would add about $16,733 interest over 5 years, on top of the mortgage interest. The example holds mortgage amount and rate constant and assumes both rates stay unchanged. Loan approval, genuine-savings rules and scheme eligibility must be checked separately; a borrowed deposit may be unacceptable.

Government incentives and schemes for first homebuyers

First-home buyers may qualify for several incentives. Grants and duty concessions have their own eligibility rules; a government loan guarantee requires a participating lender.

  • First Home Owner Grant (FHOG): A one-off grant varies by state for eligible first-home buyers who build or buy a new home. According to the national scheme, "a one-off grant is payable to first home owners that satisfy all eligibility criteria". Check your state's rules.
  • Australian Government 5% Deposit Scheme (formerly First Home Guarantee): The scheme allows eligible first-home buyers to purchase with a 5% deposit and no LMI. From 1 October 2025, the scheme expanded with income caps and place limits removed, higher property price caps, and broader eligibility.
  • Family Home Guarantee: Part of the 5% Deposit Scheme for eligible single parents and single legal guardians, with a deposit from 2%.
  • Stamp Duty Concessions/Exemptions: Many states offer lower or zero stamp duty for first homes under certain values. These tax savings depend on state eligibility rules.

Refinancing & investment loans: home equity vs personal loan

refinancing and investing personal loan vs home loan

If you already own a home and want to borrow more money (for renovations, other investments, or debt consolidation), you generally have two broad paths: access the equity in your property, or take out a separate personal loan.

Redraw accesses eligible extra repayments already made. A top-up is new borrowing that requires approval. Either has conditions; home equity is not immediately available cash.

Check access, fees and approval time for the particular product before relying on it.

Mortgage redraw

If you have been making extra repayments on your home loan over the years, you likely have "available redraw." This is the pool of extra money you've paid above your minimum scheduled repayments.

  • Access: request eligible redraw through the lender's process, subject to the loan conditions and available amount.
  • Cost: check redraw fees, minimum amounts and restrictions.
  • Timing: some lenders offer online access; others may take longer or restrict availability.
  • Assessment: redraw differs from a new loan application, but access is still controlled by the loan terms. Redrawing for private use from an investment loan can affect tax deductibility.

Mortgage top-up (the "equity" option)

A top-up asks the lender to increase the loan limit using property as security. Approval depends on your income, expenses, equity, credit and the lender's policy.

  • How it works: You submit a formal application to increase your total loan limit. For example, increasing your mortgage from $400,000 to $450,000 to pay for a pool.
  • Cost: ask for a quote for any variation, valuation, settlement or registration fees.
  • Timing: allow for a new lending assessment and any valuation. Confirm the expected timeframe with the lender.
  • LVR: extra borrowing can increase the LVR and may attract LMI or a different rate. Ask about the actual cost and any exemption before applying.

The personal loan alternative

An unsecured personal loan avoids giving the lender a mortgage over your home for that loan. It still creates a legal repayment obligation, fees and credit risk; compare its full cost with the equity option.

  • Assessment: income, expense and credit checks still apply.
  • Cost: the rate may be higher and a shorter term means a larger monthly repayment.
  • Amount limits: check the lender's permitted amount and purpose for your application.
