A fixed rate loan offers payment certainty for a set period, typically between one and five years.
That certainty appeals to endodontists who have recently transitioned from public work or associate roles into specialist practice ownership and want predictable repayments while managing fitout debt or income volatility. But locking in a rate without understanding the features attached to that loan can limit your options when your circumstances change, and they will change.
Choosing a Fixed Rate Without Checking Prepayment Limits
Most fixed rate home loans allow limited extra repayments, typically between $10,000 and $30,000 per year, before penalty interest or break costs apply. If you exceed that limit, you may face thousands of dollars in fees or forfeit the benefit of paying down your loan ahead of schedule.
Consider an endodontist who secures a fixed rate loan after completing specialist training and begins earning stronger income six months into the loan term. If the fixed loan permits only $10,000 in additional repayments per year and the borrower wants to put an extra $40,000 toward the mortgage, the lender may charge break costs based on the difference between the fixed rate and current wholesale rates. That cost can run into five figures depending on how much time remains on the fixed term.
Before committing to a fixed rate, confirm the annual prepayment limit in writing and consider whether your income is likely to increase significantly during the fixed period. If you expect bonuses, a move into private practice, or the sale of an asset, a loan with higher prepayment flexibility or a split structure may suit your situation more effectively.

Ignoring Whether the Fixed Loan Includes an Offset Account
Most lenders do not offer offset accounts on fully fixed rate loans. Some allow a redraw facility, but the two features work differently and the distinction matters.
An offset account sits separate from your loan and reduces the interest you pay based on the balance held in that account. A redraw facility allows you to withdraw extra repayments you have already made into the loan, but those funds are not liquid in the same way and some lenders restrict access or charge fees for redraw requests during a fixed term.
If you hold funds for tax purposes, operating expenses, or upcoming specialist equipment purchases, an offset account gives you flexibility without triggering break costs. A fixed loan without offset means those funds sit in a standard savings account earning minimal interest while you continue paying interest on the full loan balance.

Some lenders do offer offset on fixed loans, but the rate may be slightly higher or the product may have other restrictions. If liquidity matters to you, ask specifically whether offset is available on the fixed rate product you are considering, and compare the rate difference against the benefit of holding accessible funds.
Locking in a Rate Before Securing Pre-Approval
Some borrowers confuse a rate lock with getting loan pre-approval. A rate lock holds a specific interest rate for a set period, usually 90 days, while you finalise your purchase. Pre-approval confirms how much you can borrow and on what terms, based on your income, liabilities, and deposit.
If you lock in a rate before pre-approval is formally issued and the lender subsequently reduces your borrowing capacity or declines the application due to an undisclosed liability or serviceability issue, the rate lock becomes irrelevant. You have committed to a rate on a loan you may not receive.
Rate locks can be useful when you have an accepted offer and settlement is approaching, but they should come after you have confirmed your borrowing capacity, reviewed the loan features, and received formal approval. Some lenders charge a fee to extend a rate lock if settlement is delayed, which adds unnecessary cost if the timing was speculative.
Assuming All Fixed Rates Waive Lenders Mortgage Insurance for Dentists
Several lenders waive Lenders Mortgage Insurance for dentists, dental specialists, and related professions when borrowing above 80% of the property value. These LMI waivers for dentists typically extend to endodontists, but not every lender applies the waiver to fixed rate loans or to borrowers purchasing as first home buyers under government guarantee schemes.
If you are using the First Home Guarantee with a 5% deposit, LMI is already waived by the government guarantee. But if you are borrowing with a 10% or 15% deposit outside that scheme and relying on a profession-based LMI waiver, confirm in writing that the waiver applies to the specific fixed rate product you are selecting. Some lenders restrict waivers to variable loans or apply them only to borrowers with two or more years of post-qualification experience.
Misunderstanding this distinction can result in an unexpected LMI charge of several thousand dollars being added to your loan at settlement, increasing your borrowing requirement and potentially affecting your serviceability.
Fixing for Too Long Without Considering Your Career Timeline
Endodontists in their first year or two of specialist practice often experience income growth as referral networks develop and case complexity increases. Fixing a loan for five years may seem appealing for long-term certainty, but it also means you are locked into a rate and loan structure that may no longer suit your circumstances three years into that term.
If you expect to refinance, purchase a second property, or pay down debt more aggressively within the next few years, a shorter fixed term or a split between fixed and variable gives you more flexibility. A three-year fixed term offers certainty without over-committing, and splitting the loan allows you to direct extra repayments into the variable portion while keeping part of the loan stable.
Some borrowers fix the entire loan because the rate is lower at the time of application, but they do not account for the cost of breaking that loan early if their situation changes. Break costs are calculated based on the remaining term and the difference between your fixed rate and the current rate the lender can lend at. A five-year fixed loan broken after two years can carry a significantly higher break cost than a three-year loan in the same scenario.
Choosing a fixed rate loan that aligns with your career stage, income trajectory, and likely need for flexibility will serve you more effectively than selecting the lowest advertised rate without considering the features attached to it.

Frequently Asked Questions
Can I make extra repayments on a fixed rate home loan?
Most fixed rate loans allow limited extra repayments, typically between $10,000 and $30,000 per year, before break costs or penalty interest apply. Check the annual prepayment limit in writing before committing to a fixed rate, especially if your income is likely to increase during the fixed term.
Do fixed rate loans come with offset accounts?
Most lenders do not offer offset accounts on fully fixed rate loans, though some allow redraw facilities instead. If you need liquidity for tax or operating expenses, confirm whether offset is available on the specific fixed rate product you are considering, as rates may differ slightly.
Do LMI waivers for dentists apply to fixed rate loans?
LMI waivers for dentists and specialists are available from several lenders, but not all apply the waiver to fixed rate products or to first home buyers using government guarantee schemes. Confirm in writing that the waiver applies to the specific loan structure you are selecting to avoid unexpected costs at settlement.
Should I lock in a fixed rate before getting pre-approval?
No. Rate locks should come after you have confirmed your borrowing capacity and received formal pre-approval. Locking in a rate before approval is finalised can result in a wasted rate lock fee if your application is adjusted or declined due to serviceability or liability issues.
How long should I fix my home loan for as a first home buyer?
The right fixed term depends on your career stage and income trajectory. Endodontists early in specialist practice may benefit from a shorter fixed term or split structure to retain flexibility as income grows, rather than committing to a five-year fixed term that may carry high break costs if refinanced early.
