Quick Answer
Most doctors should review their home loan every 18 to 24 months. The right time to refinance is when you can shave 0.30% or more off your rate, unlock equity to invest, or restructure a loan that no longer fits how you earn. Your medical status matters, because most lenders will waive LMI up to 95% LVR and quietly offer rates that retail customers never see.
You Probably Took the First Decent Deal You Were Offered
Most doctors I speak to settled their home loan during a busy stretch. Registrar exams, a new fellowship year, a baby on the way. The mortgage was the box that needed ticking, not the thing to optimise.
So you took whatever the bank approved. Maybe with LMI baked in, maybe on a sharp introductory rate that quietly rolled to revert. Either way, it has been sitting there ever since.
That is fine for the first year or two. After that, your loan is almost certainly off-market. Lenders price for retention very poorly, and they especially price doctors poorly, because they know you are busy.
A quick check: pull your most recent statement and find your current variable rate. If it starts with a 6, you are paying more than you need to.
The Three Real Reasons to Refinance
Rate
The simplest case. You qualify for a doctor-specific rate at another bank that beats what you currently pay. On a $1m loan, a 0.30% cut saves roughly $3,000 a year. A 0.50% cut saves $5,000.
Doctor pricing is not advertised. You only get it through a broker or by asking the right person at the lender, with proof of AHPRA registration. Banks reserve their best discounts for borrowers they are confident will stay employed and pay down debt.
Equity
If you bought three or four years ago and your suburb has moved, you are sitting on usable equity. Refinancing lets you release that equity as a deposit for an investment property without selling anything.
For doctors this is often more tax-effective than saving a fresh cash deposit, because the interest on the equity release portion is deductible if it funds an income-producing asset. Speak to your accountant before you draw down, not after.
Structure
This is the one most doctors miss. The right structure depends on how you earn, and your earning pattern has probably changed since you took the loan.
Registrars who became consultants. Locums who set up a company. PAYG who started private practice. Each of these shifts changes what your loan should look like, including whether you want an offset, multiple split accounts, or interest-only on a portion that funds your investments.
A clean structure can save more tax over a decade than a 0.20% rate cut.
What the Refinance Actually Looks Like
The process is shorter than people expect. Three to six weeks is normal end to end, assuming your paperwork is in order.
You will need two recent payslips, two years of tax returns if you have any contractor or company income, the most recent statement on your current loan, a recent rates notice or valuation reference for your property, and proof of medical registration with AHPRA.
The valuation is the variable. If the new lender's valuation comes in soft, your LVR climbs and your rate discount can shrink. Good brokers order an upfront valuation before they submit, so you do not get surprised.
A discharge from your old lender usually adds 10 to 14 days. Plan for that, and do not refinance the week before you settle on a new property.
The Costs You Need to Weigh
Refinancing is not free. Run the numbers before you commit.
Discharge fees from your current lender usually sit between $300 and $400. Government registration of the new mortgage runs another $150 to $200. Most lenders cover incoming legals or offer a cashback that wipes both of these out.
Fixed-rate break costs are the ones that bite. If you fixed two years ago at a higher rate and break now, the calculation can run into thousands. Ask your current lender for a written break-cost quote before you decide. The number changes daily as wholesale rates move.
Cashback offers are tempting, but they should not drive the decision. A $4,000 cashback on a rate that is 0.20% worse costs you more in year one than the cashback covers.
Finally, look at the offset rules. Some doctor-specific products give you one offset, some allow multiple, some restrict offset to the main loan only. If you are running an investment portfolio, this detail matters more than the headline rate.
Key Takeaways
- Most doctors are paying 0.30 to 0.50% too much because their loan has not been reviewed since settlement
- Doctor-specific rates and LMI waivers up to 95% LVR are not advertised, you have to ask
- Refinancing is the cleanest way to release equity for an investment property without selling
- Structure matters as much as rate, especially if your income mix has changed since you borrowed
- Run the break costs and discharge fees before you commit, especially if you are still inside a fixed term
