Navigating a Rising Interest Rate Environment: What Property Investors and Developers Need to Know

Interest rates are back in focus.

While the Official Cash Rate (OCR) is considerably lower than its peak, recent movements in wholesale funding costs and longer term rates are creating renewed pressure on borrowing costs.

For property investors and developers, this raises an important question:

How do you protect your project and portfolio when the cost of debt is less predictable?

The answer isn’t necessarily to stop investing or delay projects. Instead, it is about managing your funding structure, maintaining cash flow headroom and understanding how interest rate changes affect your investment.

Why rising interest rates matter？

Interest is more than just a financing cost. It can directly affect project viability and timing.

Higher rates can impact:

• Holding costs: Particularly during longer development or sales periods.
• Cash flow: Higher payments put pressure on working capital.
• Development margins: Additional interest reduces profitability.
• Borrowing capacity: Higher debt costs affect serviceability.
• Exit timing: Delays in selling or refinancing increase financing costs.

For developers, the impact can be amplified as construction loans are progressively drawn down, increasing the outstanding balance and interest incurred.

Don’t build your strategy around a single interest rate forecast

Nobody can reliably predict where interest rates will be in six, 12 or 18 months.

Rather than making decisions based on expected rate movements, ask:

“Does the project still work if rates don’t move in the direction I expect?”

Consider modelling three scenarios:

• Base case: Your expected rate and timeframe.
• Upside case: Rates fall or the project completes ahead of schedule.
• Downside case: Rates rise, construction takes longer or sales are slower.

If the project remains viable under a reasonable downside scenario, you are starting from a stronger position.

For investors: focus on cash flow resilience

Higher interest rates can put pressure on rental yields and portfolio cash flow, particularly for highly leveraged investors.

1. Review your debt structure

Don’t wait until a loan approaches maturity.

Understand your refinancing options, current debt levels, future interest costs and whether you have sufficient equity and liquidity to manage changes.

2. Stress test your portfolio

What happens to cash flow if rates increase another 1%, or a property remains vacant longer than expected?

Identifying pressure points early gives you time to respond.

3. Maintain liquidity

In an uncertain rate environment, liquidity can be just as valuable as equity.

Cash reserves or accessible equity provide flexibility when unexpected costs arise or opportunities present themselves.

For developers: interest is a project cost, so manage it like one

Interest should be a core component of the project budget, not an afterthought.

Consider the full funding lifecycle:

Acquisition → Consenting → Construction → Completion → Sales → Repayment

Each additional month carries a financing cost, so the question isn’t simply “What interest rate am I paying?” but also:

“How long will I need the funding for?”

A slightly higher rate with a flexible funding structure may be more valuable than a lower rate that creates delays or requires restructuring partway through.

Build a realistic interest rate buffer into your feasibility

Allow for higher rates, longer construction periods, slower sales and increased costs.

The objective isn’t to make every project look unattractive. It is to understand the breaking points so you can make informed decisions about debt, equity and contingency.

Consider the whole funding structure, not just the headline rate

• Interest rate is only one part of the funding equation.
• When comparing options, consider:
• Interest rates and establishment fees
• Loan-to-value ratio
• Capitalised interest options
• Drawdown and repayment flexibility
• Early repayment provisions
• Valuation, quantity surveyor and inspection requirements
• The lender’s ability to accommodate project changes

For developers, certainty and flexibility have real financial value.

A lender that understands the development and responds quickly when circumstances change may prevent delays that cost more than a small difference in the headline rate.

Get your lender involved early

One of the most effective ways to navigate changing rates is to have the funding conversation early.

Don’t wait until an existing facility approaches maturity or development is underway.

Early engagement helps you understand refinancing options, assess debt and equity requirements, and plan funding around the project’s timeline.

This is particularly important when moving between acquisition, pre-development, construction and repayment. Planning these transitions can help avoid unnecessary pressure at critical stages.

Don’t let the interest rate environment stop good projects

Higher rates naturally make investors and developers cautious, but changing conditions can also create opportunities.

Some projects will still stack up because of their location, underlying land value, development potential or opportunities to add value.

The key is understanding the numbers and ensuring the funding structure matches the project.

The goal isn’t necessarily to predict the next interest rate move. It’s to structure investments so they remain resilient.

The bottom line

Interest rates will continue to move through economic cycles. Investors and developers can’t control their direction, but they can control how they prepare.

Stress test the numbers, protect cash flow, maintain liquidity, allow for delays and choose funding that balances cost, certainty and flexibility.

At Cressida Capital, we understand that property funding doesn’t happen in isolation. The right structure needs to reflect the property, the borrower’s objectives and the pathway from acquisition through to repayment.

If you’re considering an acquisition, development or refinance, talking to your lender early can help you understand your options before the pressure is on.
