Refinancing for Property Investors: What You Need to Know

Most people think refinancing is just about chasing a lower interest rate. For property investors, there's often far more to consider. Strategic refinancing can reset interest-only periods, improve borrowing capacity, give you control over your portfolio, and set you up for future purchases.

Why Rate Chasing Alone Isn't Enough

Yes, a lower rate saves money. But for investors, the decision is more nuanced. You need to consider all costs including discharge and registration fees of $200-500, new lender's legal fees which are often covered but not always, valuation costs of $600-1,000 per property, potential cash contributions as some banks require 1% of loan value, and break fees if exiting fixed rates early.

A 0.2% rate saving sounds good, but if it costs $5,000 to refinance a $400,000 loan, you need 2+ years to break even.

Strategic Reason #1: Resetting Interest-Only Periods

Most banks cap interest-only lending at five years. After that, you're required to switch to principal and interest repayments, which significantly increases your cash flow requirements.

For investors with multiple properties, that difference across a portfolio can be substantial. Moving to a new lender resets the clock, allowing you to secure a fresh five-year interest-only period and maintain cash flow for continued investing or other purposes.

Interest-only lending is harder to obtain than it was five years ago. Banks now scrutinise these applications more closely, and not all investors will qualify.

Strategic Reason #2: Escaping Cross-Collateralisation

When you have multiple loans with one bank, they typically cross-collateralise them, meaning all your properties secure all your loans.

With cross-collateralisation, when you sell one property, the bank can retain the sale proceeds to reduce your overall debt across the portfolio. You don't automatically get the surplus. Without cross-collateralisation, each property secures only its own loan, and when you sell, the surplus proceeds are yours to use as you choose.

Consider this example: you own three properties with $1.2M total lending at Bank A. Property 1 is worth $600K and owes $400K, Property 2 is worth $500K and owes $450K, and Property 3 is worth $400K and owes $350K. You sell Property 1 for $600K. With cross-collateralisation, Bank A could potentially retain the $200K surplus to reduce your overall exposure. Without it, you'd receive the $200K to invest elsewhere.

Refinancing helps by splitting your portfolio across multiple lenders. Each lender only has security over properties with them, giving you control over sale proceeds.

Strategic Reason #3: Improving Serviceability

Banks stress-test your ability to repay at rates higher than current market rates, typically 8-9%. This "serviceability" calculation often prevents investors from borrowing more, even when they're comfortably covering current payments.

Refinancing can help in several ways. Moving from 25 to 30 years reduces the monthly payment the bank calculates in their stress test. Some banks treat interest-only loans more favourably in serviceability calculations. Each bank calculates serviceability differently, so ANZ might decline you while Westpac approves the same application. Banks assess rental income at 65-80% of actual rent, and some are more generous than others.

Strategic Reason #4: Accessing Equity

Property values rise. Refinancing lets you access that accumulated equity without selling. For example, if you bought for $600K with $120K deposit, and the property is now worth $800K with a current loan of $480K, your available equity at 70% LVR is $560K minus $480K, giving you $80K. That $80K could fund part of your next deposit.

Your current bank may not offer the best terms for equity release. Refinancing lets you shop around for better rates on the additional lending.

Strategic Reason #5: Portfolio Restructuring

As portfolios grow, ownership structures often need to change. This might involve moving properties into trusts, transferring between entities, or changing from personal to company ownership. Some banks are more flexible with entity restructures than others. Refinancing can facilitate these changes while potentially improving your overall lending terms.

When Refinancing Doesn't Make Sense

Don't refinance if break fees exceed savings, so calculate carefully before breaking fixed rates. Avoid refinancing if you're buying soon, as multiple recent credit enquiries can affect future applications. If the current lender will match your terms, sometimes threatening to leave gets you what you need without the hassle. Finally, if your situation has changed and income has dropped or debt has increased, you might not get the same terms elsewhere.

The Refinancing Process for Investors

Start by reviewing your current position, listing all properties, current values, loan balances, rates, and structures. Identify your objectives and what you're trying to achieve, whether that's lower rates, resetting interest-only periods, or accessing equity. Get multiple quotes by comparing at least 3-4 lenders and including non-bank lenders for investment properties. Calculate true costs including all fees, not just the headline rate. Consider timing, and if fixed rates are expiring soon, wait rather than paying break fees. Execute strategically by moving one property at a time if needed to manage risk and cash flow.

Working with a Mortgage Adviser

Investor refinancing is complex. A good mortgage adviser will know which banks are lending to investors, which changes constantly. They understand each bank's serviceability calculations, can structure applications to maximise approval chances, negotiate on your behalf, and coordinate the process across multiple lenders. The value they provide typically far exceeds their cost, which is often zero to you since they're paid by lenders.

Refinancing as Strategy, Not Just Rate Shopping

For property investors, refinancing is a strategic tool - not just rate shopping. Whether you're resetting interest-only periods, escaping cross-collateralisation, improving serviceability, or accessing equity, the right refinancing strategy can significantly impact your portfolio's performance and growth potential.

Before making any moves, model the scenarios carefully. What looks good on paper might cost more than it saves once all fees are factored in.
