What is a Rate Lock Home Loan?

A rate lock home loan is an agreement between you and your lender to "lock in" an interest rate for a specified period, typically ranging from 60 to 90 days. During this period, even if the lender’s interest rates rise, your agreed rate remains unchanged, providing certainty and potentially saving you money if rates climb before your loan is finalised.

Benefits of a Rate Lock

Stability in a Volatile Market

Interest rates can be unpredictable, influenced by economic conditions both domestically and globally. By securing your rate, you are protected against the volatility that could impact your mortgage repayments.

Peace of Mind

Knowing your exact future repayments allows for better budgeting and financial planning. This is particularly beneficial for first-time homebuyers who need to manage their finances carefully.

Potential Cost Savings

If rates rise after you've locked in your rate, the savings on your monthly payments can be considerable over the life of your loan. However, it's crucial to weigh these potential savings against any fees associated with the rate lock.

Practical Tips and Advice

Understand the Terms

Before committing to a rate lock, ensure you fully understand the terms. This includes any fees involved, the duration of the lock, and what happens if your loan isn't settled within the lock period.

Timing is Key

Locking in a rate too early or too late can negate the benefits. Monitor economic indicators and consult with your mortgage broker to determine the optimal time to secure your rate.

Check for Flexibility

Some lenders may offer a "float down" option, allowing you to benefit from a lower rate if rates decrease during your lock period. This can offer added security and potential savings.

Common Mistakes to Avoid

Ignoring Fees

Rate lock fees can vary between lenders. These fees can often be a flat rate or a percentage of the loan amount. Always factor these into your decision-making process.

Misjudging Settlement Time

If your loan settlement is delayed beyond the lock period, you may lose the locked rate and have to accept the current rate. Ensure your settlement timeline is realistic and account for potential delays.
