Many Doctors Can Borrow More Than They Realise

One of the most common misconceptions among doctors is that lenders only assess their base salary.

In reality, many lenders take a much broader view of income when assessing medical professionals. Depending on the lender and how the application is structured, overtime, penalty rates, locum work, private billing income and contract earnings may all contribute toward borrowing power.

For doctors looking to purchase their first home, upgrade, invest or refinance, understanding how lenders assess medical income can significantly impact borrowing capacity.


Why Medical Professionals Are Assessed Differently

Medical professionals are often viewed as lower-risk borrowers due to:

  • Strong long-term employment prospects
  • Stable income growth
  • High earning potential
  • Consistent demand for services
  • Predictable career progression

Because of this, many lenders have specialist policies designed specifically for medical professionals.

These policies often provide:

  • Higher borrowing capacity
  • Recognition of multiple income streams
  • Up to 95% borrowing with no Lenders Mortgage Insurance
  • Flexible assessment criteria

Differential Search Analysis

A review of search results across Google, Bing and major Australian lending websites reveals a common theme: most lenders mention medical lending benefits but provide limited detail about how income is assessed.

Many articles focus on:

  • No LMI benefits
  • Higher borrowing capacity
  • Professional discounts

However, few explain the practical differences between lenders.

Some lenders may use 100% of overtime income. Others may use:

  • 80%
  • 70%
  • An average over two years
  • An average over six months

This creates significant differences in borrowing outcomes. A doctor earning the same income may receive dramatically different borrowing limits depending on lender selection.


Income Types That May Be Recognised

Base Salary

This remains the foundation of most applications.

Overtime

Many medical professionals regularly earn overtime through:

  • Extended shifts
  • On-call work
  • Additional hospital duties

Some lenders will fully recognise this income. Others apply discounts.

Penalty Rates

Weekend, overnight and public holiday work can contribute significantly to overall earnings. Lender treatment varies considerably.

Locum Income

Locum income is becoming increasingly common among:

  • General practitioners
  • Specialists
  • Registrars

Many lenders now have dedicated policies recognising this income source.

Private Billing Income

For doctors operating private practices, lenders may assess the following, depending on business structure:

  • Business income
  • Distribution income
  • Personal drawings

Contract Income

Contract arrangements are increasingly common within healthcare. Specialist lenders often assess contract income more favourably than traditional banks.


Why Lender Choice Matters

Not all lenders assess medical income equally. Consider the following example.

Doctor A earns:

  • $180,000 base salary
  • $40,000 overtime
  • $20,000 locum income

Depending on policy, the assessed income could differ substantially:

  • Lender 1 may assess $180,000 only
  • Lender 2 may assess $220,000
  • Lender 3 may assess $240,000

The result can be a borrowing power difference of hundreds of thousands of dollars.


Doctor Home Loans and No LMI

Many doctors are also unaware they may qualify for up to 95% borrowing without Lenders Mortgage Insurance (LMI).

Depending on purchase price and lender policy, LMI savings can exceed:

  • $30,000
  • $50,000
  • $80,000+

This can dramatically improve purchasing power.


Peter’s Perspective

“One of the most common conversations I have with doctors is around income. Many are surprised to learn that different lenders assess overtime and locum work very differently. Choosing the right lender can significantly change borrowing capacity. In some cases, we’ve seen doctors qualify for substantially more simply because their income has been structured and presented correctly.”


Common Mistakes Doctors Make

Applying directly with one bank

Banks can only offer their own policies.

Underestimating borrowing power

Many doctors assume they can only borrow against base salary.

Not exploring medical-specific lending

Specialist policies can deliver significantly better outcomes.

Delaying conversations

Many doctors wait until they have found a property before reviewing borrowing capacity.


Why Use a Mortgage Broker for Doctor Home Loans?

An Australian mortgage broker can:

  • Compare multiple medical lending policies
  • Structure complex income correctly
  • Identify lenders offering no-LMI benefits
  • Improve borrowing outcomes
  • Save time and reduce uncertainty

This is often where the biggest advantage lies.
