If you’re asking “how much can I borrow for a home loan?”, the answer depends on more than your salary, even if you’re a doctor, dentist or other healthcare professional.
Healthcare professionals may have strong earning potential, but lenders consider your broader financial position when assessing how much they may be willing to lend. This includes your income, living expenses, existing debts, dependants and other financial commitments.
Some lenders also have policies designed for eligible medical professionals, which may provide access to different lending options.
Understanding how lenders assess your finances can help you set a realistic property budget. Below, we explain the key factors that affect how much you may be able to borrow and what to consider before applying.
Keep Your Practice Up to Date
How Much Can I Borrow for a Home Loan and How Do Lenders Calculate It?
There is no universal income multiple that determines how much a lender will let you borrow. Each lender uses its own policies, serviceability calculations and assessment criteria. This means the same healthcare professional could receive different borrowing estimates from different lenders.
How Much Can I Borrow for a Home Loan Based on My Income?
Income is an important part of the assessment, but lenders look closely at where it comes from and how consistent it is. Depending on your circumstances, they may consider:
- Base salary and regular employment income
- Overtime, allowances and additional shifts
- Contractor or locum income
- Self-employed income if you own a practice
- Rental income and other acceptable income sources
Not every income source is necessarily assessed in full. Lenders may apply different criteria to overtime, allowances, variable earnings and rental income. They may also consider how long you have been receiving that income and whether it is likely to continue.
This can be particularly relevant for healthcare professionals with multiple or less conventional income streams. A broker experienced in medical lending can help identify how different lenders may assess your circumstances.
Why Your Salary Is Only Part of the Calculation
Your borrowing capacity reflects more than what you earn. Lenders also consider your expenses, existing debts, dependants and other financial commitments.
A simple way to understand the relationship is:
Assessable income + financial position + lender policy = potential borrowing amount
This is not an actual lender formula, but it illustrates why income alone cannot determine the answer. Two doctors earning the same salary may receive different borrowing estimates if one has higher living expenses, more debt or additional financial commitments.
What Affects Your Home Loan Borrowing Power?
Several factors can increase or reduce the amount a lender is prepared to offer. Understanding them can give you a clearer idea of where you stand before applying.
1. Income and Employment Structure
Lenders consider both how much you earn and how you earn it. PAYG income may be relatively straightforward to verify, while contractors, locums and practice owners may need to provide additional evidence of their earnings. Variable or self-employed income may also be assessed differently between lenders.
2. Existing Debts
Your existing financial commitments can reduce the income available for future mortgage repayments. Lenders may consider:
- Credit card limits
- Car and personal loans
- HELP debt
- Investment loans
- Existing mortgages
- Relevant business debts
Importantly, a lender may consider your total credit card limit rather than only the amount currently owing. So, when asking “how much can I borrow for a home loan?”, keep in mind that even a high unused credit limit could reduce the amount a lender is willing to offer.
3. Living Expenses and Dependants
Regular household spending also affects your home loan borrowing power. This may include groceries, utilities, insurance, childcare, school fees and other ongoing expenses. Having dependants can also influence the lender’s assessment of your household costs.
4. Deposit and Available Equity
A larger deposit generally reduces your loan-to-value ratio (LVR), which is the percentage of the property’s value you need to borrow. Existing homeowners may also be able to use available equity, depending on their circumstances.
Eligible healthcare professionals may have access to profession-specific lender policies, including higher LVR options or Lenders Mortgage Insurance waivers. Eligibility varies by lender and profession.
5. Loan Term and Interest Rate
The loan term and the interest rate used in the lender’s serviceability assessment can also affect the amount you may qualify for. A lender tests whether repayments remain affordable under its assessment criteria rather than considering the requested loan amount alone.
Why Home Loans for Doctors May Be Assessed Differently
Some lenders offer specialised policies for doctors and other eligible healthcare professionals because they may consider certain medical occupations to have a lower lending risk.
These policies can provide access to benefits that may not be available to all borrowers, including:
- Higher loan-to-value ratios (LVRs), potentially allowing a smaller deposit
- Lenders Mortgage Insurance (LMI) waivers for eligible applicants
- Different lending criteria based on professional qualifications and employment circumstances
However, not all lenders offer the same benefits. Eligibility may depend on your occupation, professional registration, income and employment status.
When comparing home loans for doctors, it’s important to understand which lender policies apply to your circumstances rather than assuming every medical professional qualifies for the same benefits.
Does Being a Doctor Mean You Can Borrow More?
Not automatically. While specialised lending policies may offer greater flexibility, they do not guarantee a higher loan amount.
Lenders must still assess your income, expenses, existing debts and ability to meet repayments.
This is why comparing medical professional home loans involves more than looking at interest rates or deposit requirements. The lender’s assessment criteria can also influence your available options.
How Lenders Test Whether You Can Afford the Loan
Before approving a mortgage, lenders assess your ability to meet repayments. This process is called serviceability.
Rather than calculating affordability using only the advertised interest rate, lenders apply a serviceability buffer to account for potential interest rate increases.
According to the Australian Prudential Regulation Authority (APRA), the minimum mortgage serviceability buffer for APRA-regulated banks remains at 3 percentage points above the loan interest rate.
For example, if your loan has an interest rate of 6%, a bank would generally assess your ability to repay it at a rate of at least 9%.
Lenders also consider your existing debts, living expenses and other financial commitments when determining affordability.
Because lenders use different assessment models, the amount you qualify for may vary between institutions.
If you’re wondering how much can I borrow for a home loan, understanding these serviceability requirements can help explain why borrowing estimates differ between lenders.
What Could Borrowing Capacity Look Like for Different Healthcare Professionals?
There is no standard borrowing amount for healthcare professionals. The examples below show how different circumstances may influence a lender’s assessment. They are illustrative only and do not represent guaranteed lending outcomes.
Even two healthcare professionals earning the same gross income can have different borrowing capacity. One may have a larger deposit and fewer debts, while another may have significant existing commitments or higher household expenses.
This is why a generic income multiplier cannot reliably answer how much can I borrow for a home loan. Your overall financial position and the lender’s assessment criteria need to be considered together.
How to Improve Your Home Loan Eligibility Before Applying
Preparing before you apply can help you understand your financial position and identify issues that may affect a lender’s assessment.
To strengthen your home loan eligibility, consider the following:
- Review unused or unnecessarily high credit card limits
- Consider reducing unsecured debts where appropriate
- Build and maintain a consistent savings history
- Keep payslips, tax returns and other relevant income documents organised
- Review your regular and discretionary expenses
- Check your credit report and address any incorrect information
- Understand how HELP debt and other financial commitments affect serviceability
- Avoid taking on unnecessary new debt before applying
- Establish a realistic property budget before making an offer
These steps can also give you a clearer picture of your home loan borrowing power before you start looking at properties.
However, increasing the amount a lender may offer should not be the only objective. Avoid making significant financial decisions purely to qualify for a larger loan. A sustainable home loan should reflect what you can comfortably manage alongside your other financial commitments and goals.
Why Online Borrowing Calculators Are Only a Starting Point
Online calculators can provide a useful initial estimate if you are asking how much can I borrow for a home loan, but the result should be treated as a starting point rather than a lending decision.
Calculators may not fully account for:
- Profession-specific lender policies
- Complex or variable medical income
- Contractor or locum arrangements
- Practice ownership and business liabilities
- Different lender expense assumptions
- Individual lender assessment criteria
This is particularly relevant when comparing home loans for doctors, as eligible applicants may have access to lender policies that a general calculator does not consider.
A calculator works from assumptions. An actual lending assessment considers your financial circumstances, income structure and the policies of the lender assessing your application.

Frequently Asked Questions
Can overtime and shift allowances be included in a healthcare professional’s income?
Potentially. Some lenders may include overtime, shift allowances or other regular earnings when assessing income, but the way they treat these amounts can vary. They may look at how consistently the additional income has been earned and whether it is likely to continue. This can be particularly relevant for hospital-based healthcare professionals whose total earnings are significantly higher than their base salary.
How can being on probation affect a healthcare professional’s home loan application?
Being on probation does not necessarily prevent you from getting a home loan. However, lenders may consider your employment history, profession and the conditions of your new role. A doctor or other healthcare professional moving between similar positions may be assessed differently from someone entering a completely new industry. Lender policies can vary, so changing jobs shortly before applying is worth discussing with a broker.
Can income from more than one healthcare job be considered?
It may be possible for income from multiple roles to be considered. For example, a doctor might work at a hospital while also earning income through private consulting or locum work. The lender may want evidence showing how long each income stream has been received and whether it is ongoing. Requirements can differ depending on the lender and type of employment.
Does owning a medical or dental practice affect a personal home loan application?
Yes, it can. A lender may need to consider your relationship with the business when assessing your personal income and liabilities. Depending on the business structure and lender requirements, this could involve reviewing company or trust financial information alongside your personal finances. Existing business borrowings or guarantees may also be relevant to the assessment.
Can I get pre-approval before I have chosen a property?
In many cases, yes. Pre-approval can provide an indication of what a lender may be prepared to offer based on the information available at that time. However, it is generally conditional rather than a guarantee of final approval. The lender may still need to assess the chosen property, verify updated financial information and confirm that its lending criteria continue to be met before providing unconditional approval.
