When to Research Before Getting an Investment Loan

Getting your market research right before you borrow matters more than the loan itself.

Most people looking at an investment property in Terrigal focus on whether they can get finance. The real question is whether the property will do what you need it to do. That's a research question, not a loan question, and it needs to happen before you talk to a lender.

What Market Research Actually Means for Investment Borrowing

Market research in the context of getting an investment loan is about figuring out whether a specific property is likely to hold or increase its value, attract tenants, and cover enough of its own costs that you can service the loan. You're trying to work out vacancy rates for the property type you're considering, what rent you can actually expect, and what's driving demand in that part of Terrigal. If you can't answer those questions with local data, you're guessing, and lenders can tell.

Rental Yield and Borrowing Capacity Are Connected

Your borrowing capacity for an investment property includes rental income in the calculation, but lenders don't just take your word for it. They'll discount the rent you declare by anywhere from 20 to 30 per cent depending on the lender and the property type. That discount is meant to cover vacancy, management fees and the possibility you've been optimistic. If your research shows the area has a 4 per cent vacancy rate and the unit you're looking at is in an older block with no parking, you need to account for longer gaps between tenants and potentially lower rent than the newer stock around it. That flows directly into how much you can borrow and whether the numbers actually work.

Consider someone looking at a two-bedroom unit in one of the older blocks near the beach. They see similar units advertised at a certain weekly rent and assume that's what they'll get. Research into actual leased properties in that building over the past 12 months shows the real figure is lower and that most turnovers involve at least a six-week gap. The rental income they can reliably declare to the lender drops, their serviceability drops with it, and suddenly they're either borrowing less or looking at a different property.

Interest Only Loans and the Rental Income Assumption

A lot of investors in Terrigal go with interest-only repayments to keep cash flow manageable, particularly if they're holding the property for capital growth rather than immediate income. That structure makes sense in some situations, but it also means your entire serviceability case rests on rental income covering interest and holding costs. If your market research overestimated the rent or underestimated the vacancy rate, you've got a problem. Lenders assess interest-only investment loans at the variable rate plus the serviceability buffer, which sits at 3.0 percentage points above the loan product rate. If the rent doesn't cover that amount after the lender's shading, you're paying the shortfall yourself, and that needs to fit within your overall debt-to-income position.

Terrigal's Two-Speed Rental Market

Terrigal has a permanent rental market and a short-term holiday rental market, and they don't behave the same way. The beachside precinct between The Esplanade and Terrigal Drive has strong short-term demand, particularly over summer, but permanent rental supply in that area is harder to fill outside the holiday window unless the property suits downsizers or professionals who want a sea change. The areas further back from the water, around Trafalgar Avenue and towards Erina, tend to attract longer-term tenants, including families who want the school zone and workers commuting to Gosford or Sydney. If you're borrowing to buy in the beachside area and your strategy depends on permanent rental income, your research needs to show there's tenant demand for that property type outside the peak months. If there isn't, you're either running it as a short-term rental with the higher management costs and council restrictions that come with that, or you're holding a property that sits empty for part of the year.

LVR and How Much Research You Need

The loan-to-value ratio you're aiming for changes how much risk you're taking on and how much precision you need in your research. Borrowing at 90 per cent LVR on an investment property means you're paying for lenders mortgage insurance, you're more exposed to any value drop, and you've got less buffer if the rental income doesn't perform as expected. At that level, your research needs to be detailed enough to justify the assumption that this specific property will meet your income and growth projections, because there's no equity cushion if it doesn't. Borrowing at 70 or 80 per cent LVR gives you more room for the market to move, but it doesn't mean you can skip the research. It just means the consequences of getting it wrong are slower to arrive.

What the Negative Gearing Changes Mean for Your Research Timeline

From the 2027-28 income year, losses on established residential investment properties bought after May 2026 can only be offset against income from other residential properties, not against your salary. Properties classified as eligible new builds are exempt. If you're looking at an established property in Terrigal and you're planning to negatively gear it in the traditional sense, that option expires on 30 June 2027 for anything you buy now. Your research needs to factor in whether the property can move closer to neutral or positive cash flow within a realistic timeframe, because the tax treatment that made high negative gearing tolerable is gone. That shifts the focus from maximum capital growth at any holding cost to properties that can actually generate decent rental returns in a local market where you understand the demand drivers.

How We Help You Research Before You Borrow

We work with investors around Terrigal who want to make sure the property stacks up before they commit to a loan structure. That means talking through what you're seeing in the market, what the rental data actually says, and whether the numbers you're working with are realistic given the area and the property type. Once that's clear, we can look at loan options that match the strategy, whether that's interest-only to manage cash flow, a split between fixed and variable, or principal and interest if you're planning to hold long term and want the debt reducing. If you're also looking at refinancing an existing property to pull equity for the deposit, that's part of the same conversation, because it all needs to fit within your overall borrowing capacity and serviceability.
