Specialists in high-income professional lending, with options from a wide panel of lenders.

You've spent a decade in medical school, residency, and specialty training. You've built a successful practice and your income reflects that achievement. But when you go to apply for a home loan, lenders treat you like any other borrower—and that's where the problem starts.

High-income professionals (doctors, surgeons, specialists) have unique lending situations that standard home loan processes don't handle well. This guide shows you how to navigate the system, maximize your borrowing power, and negotiate rates that reflect your actual financial strength.

The Doctor's Lending Problem: Why Standard Lenders Fail You

Many doctors earn high incomes, yet some lenders may assess your income conservatively. Here's why:

The result: You can actually afford a $1.2M home, but lenders will only approve $800k. You're underlevering against your real income.

Strategy 1: Present Income Correctly (Don't Leave Money on the Table)

The first step is helping lenders see your true income, not just your tax return.

For salary + partnership income:

Impact: Instead of lenders using your tax return ($280k after deductions), they see salary + distributions ($420k). This may increase what you can borrow, depending on the lender.

For locum work and private billing:

Get documentation:

Strategy 2: Handle HELP Debt Strategically

Many doctors still carry HECS/HELP debt. Lenders count this as a full debt obligation, but it's not really a monthly payment—it's income-contingent.

Option A: Pay it out

Before applying for a mortgage, make a lump sum payment to clear HELP debt. This immediately increases your serviceability by ~$300–$500/month. Cost to you: ~$100k. Benefit: may increase your borrowing power, depending on the lender. ROI: Often worth it if you're close to a property goal.

Option B: Negotiate with lenders

Ask specialist lenders to use the actual HELP repayment amount (often $200–$300/month) instead of calculating it from the outstanding balance. This is legitimate because HELP is income-contingent and lower-priority than a mortgage.

Strategy 3: Use Specialist High-Income Lenders

Not all banks understand high-income professional lending. The big four banks will underestimate your income. Instead, use:

Illustrative example: A surgeon earning $420k applies to a major bank → approved for $900k. Same surgeon applies to a lender that accepts an accountant letter → approved for $1.4M. Same income, different lender = $500k more borrowing power.

NB: This is an illustrative example only. It may or may not reflect an actual client situation, and it is not a promise of any result. Individual circumstances and lender criteria vary.

Strategy 4: Negotiate Professional Rates

High-income earners should get better rates. You have:

Negotiation points:

Some borrowers may receive a discount versus the advertised rate, depending on the lender and loan.

Strategy 5: Tax-Optimize Your Loan Structure

If you have investment properties or rental income, structure your home loan strategically for tax:

FAQ: High-Income Professional Lending

How much can I borrow as a doctor?

Many banks will lend 5–6x your annual income. If you earn $300k, that's $1.5–1.8M. But with specialist lenders and proper income documentation, some will go to 7–8x income ($2.1–2.4M). Your actual capacity depends on expenses, debts, and risk appetite.

Should I pay out HELP debt before applying for a mortgage?

Not always. If you owe $100k and paying it would delay your home purchase by a year, it's not worth it. But if you have the cash and you're ready to buy now, clearing HELP may increase your borrowing power and simplify serviceability, depending on the lender.

Can I use locum income for a mortgage application?

Yes, but you need documentation. Lenders want to see 2+ years of consistent locum income, ideally with letters from the locum providers and accountant confirmation. Sporadic locum shifts won't count; regular streams (e.g., $5k/month from a locum agency) will.

What if I'm in my first 1–2 years of practice?

Many banks won't lend full amounts in Year 1. But get an accountant letter projecting income growth based on historical practice benchmarks. Specialist lenders will use this to assess your long-term earning capacity, not just Year 1 actuals.

Do surgeons get better rates than GPs?

Not explicitly. But surgeons typically earn more, so they seek approval for larger loans with better margins. Pricing can vary by loan size and lender, and larger loans may sometimes be priced differently.
