Doctor Home Loans Sydney — Complete Guide for Medical Professionals

By the Mortgagefy Team · Published Sept 14, 2026 · 7 min read

You're a GP earning $160,000+ annually. Your payslip shows $120k base salary — but that's not your real income. Add shift premiums, on-call pay, weekend work, and locum shifts, and you're making serious money. Yet when you apply for a mortgage, banks see only your base salary and tell you that you "don't qualify" for what you need.

This isn't a you problem. It's a system problem. Standard banks built their lending around PAYG employees with fixed, predictable income. Medical income doesn't fit that mold. Variable hours, weekend premiums, shift penalties, on-call allowances — these are all real, documented, repeating income, but legacy lending systems struggle to assess them fairly.

How Banks Assess Doctor Income

Mainstream lenders typically assess medical professionals in one of two ways — both of which undervalue your true earning capacity:

Method 1: Base Salary Only
Banks look at your base salary ($120k) and ignore shift premiums, on-call pay, and weekend allowances. Your borrowing capacity is then capped at roughly 4-5× base salary, or $480k-$600k. This leaves you $100,000+ short of what you can actually afford.

Method 2: Last 2 Years Tax Returns
Some lenders will look at your tax return to capture total income. But if you've recently changed hospitals, completed a residency, or shifted from full-time to part-time, your tax return doesn't reflect your current earning trajectory.

Method 3: Specialist Assessment (What You Need)
Specialist lenders understand medical income. They assess your base salary, plus documented shift allowances, on-call pay, overtime, and locum earnings shown on payslips and employer letters. This can unlock $80,000+ in additional borrowing power. Get a specialist doctor mortgages assessment →

What Income Counts as "Medical Income"?

If you're a doctor, most or all of this income is documented and legitimate:

Base Salary: Your contracted annual salary
Shift Premiums: 15-30% loading for after-hours, weekends, public holidays
On-Call Pay: Documented on payslips, typically 10-20% of base
Overtime & Additional Shifts: Hours worked beyond contracted time
Locum Work: Shifts at other hospitals or private locum agencies
Private Practice Income: For practitioners, documented via tax returns and bank statements
Sessional Income: Teaching, consulting, research allowances

All of this is repeating, documented, and verifiable. Specialist lenders know this and structure your assessment to capture your full earning power.

Documentation You'll Need

Prepare these documents to get assessed fairly:

Last 2 years payslips (showing base + all allowances)
Employment contract or letter from your employer confirming salary and allowances
Last 2 years tax returns
Bank statements (6-12 months) showing regular deposits
Letter from your employer confirming income stability and likelihood of continuation
For locum/private work: invoices, ABN history, or agency contracts

This documentation proves your income is real, repeating, and sustainable — not one-off bonuses or sporadic shifts.

Illustrative Example: Dr. Sarah

Sarah is a GP earning:

Base salary: $120,000
Shift premiums: $30,000
On-call pay: $15,000
Weekend work: $12,000
Total income: $177,000

At a mainstream bank: Assessed on $120k base → borrows $480k-$600k → limited options.

With specialist lender: Assessed on $177k full income → borrows $680k-$850k → buys the home she can actually afford.

That's a $200,000+ difference in borrowing power — simply from being assessed fairly.

Common Concerns Answered

What if I'm on a fixed salary with no allowances?
You'll be assessed like a PAYG employee, and standard banks will work fine for you. If you have shift work but it's not formally documented, a specialist lender can still help — they may request a letter from your employer confirming the likelihood of ongoing shift work.

What if I recently changed hospitals?
You'll need an employment contract from your new employer plus payslips showing your new income structure. Most lenders require 3+ months in the new role, but some will consider earlier with a solid contract.

What if I'm doing locum work?
Locum income is real income. Bring invoices, ABN history, or agency contracts showing the pattern and sustainability of locum work. Lenders will assess this as repeating income if you can show 12+ months of history.

Will I need a larger deposit?
No. Medical professionals with documented income are approved at standard LVRs (80-90% depending on serviceability). A 20% deposit removes LMI, but it's not required if your income is solid.
