If you bought your Hills District home five or more years ago, the chances are very strong that you are now sitting on hundreds of thousands of dollars of equity. Castle Hill medians have moved from about $1.1 million in 2018 to $1.65 million today. Kellyville, Bella Vista and Norwest have followed similar curves. That equity is not just a number on your statement. With the right loan structure, it becomes the deposit for your next property.
This guide walks through exactly how Hills District homeowners are using equity in 2026 to buy investment property, what your bank will and will not let you do, and how to keep your tax position clean from day one.
How home equity actually works (useable vs total equity)
Equity is the gap between what your home is worth and what you still owe on it. If your home in Bella Vista is worth $1.65 million and your loan balance is $640,000, your total equity is $1.01 million. That total equity number feels great, but it is not the figure your lender will actually let you use.
Banks will not let you borrow against the last 20 percent of your home's value without charging Lenders Mortgage Insurance (LMI). They draw a line at 80 percent of the property value, which they call the safe lending limit.
Useable equity is what is left below that 80 percent line, after you take into account what you already owe.
The maths is simple:
- Take your current property value.
- Multiply by 0.80.
- Subtract your current loan balance.
That number is your useable equity. It is the money a lender will release to you without forcing LMI on the deal.
For most Hills District clients, the gap between total equity and useable equity is significant. A family with $1.01 million of total equity might only have $680,000 of useable equity. The rest is locked behind the 80 percent line.
How much equity you can access without LMI in 2026
Most major lenders in 2026 still hold the LMI threshold at 80 percent of property value. That is the comfortable zone where lenders do not need insurance to protect themselves if you default.
Some lenders will push to 85 percent or even 90 percent if you accept LMI. For an investment purchase, that can sometimes make sense, especially when capital growth on the new property is expected to outpace the LMI premium. But for most clients we work with at RyRo, the 80 percent line is the right place to draw your useable equity.
There are three reasons we usually stop at 80 percent for investment equity releases:
- LMI on equity releases is often higher than LMI on a first home purchase because lenders see refinances as higher risk.
- Pushing your loan-to-value ratio (LVR) above 80 percent reduces your buffer if rates move or if values dip.
- Most clients want flexibility to release more equity later for renovations, a second investment or to help children with a first home. Going to 90 percent now removes that future option.
If you are working with a strong lender and the deal stacks up, going to 85 percent can be worth a conversation. If you are not sure where the line should be, that is the kind of question a Hills District mortgage broker can answer in 20 minutes after looking at your statements.
Calculating your usable equity (worked Hills District example)
Let's run through a real Castle Hill scenario, because numbers make this clear.
The family bought their four-bedroom Castle Hill home in 2018 for $1.1 million. They borrowed $880,000 on a 30-year principal and interest loan. Eight years on:
- The home now values at $1.65 million (recent comparable sales in their pocket of Castle Hill).
- Their loan balance has been paid down to $640,000.
- They have made a few extra repayments along the way and the loan is on track.
Their total equity sits at $1.65 million minus $640,000, which equals $1.01 million.
Their useable equity is calculated like this:
- 80 percent of $1.65 million is $1,320,000. That is the maximum the bank will lend against the home.
- Subtract the current loan balance of $640,000.
- The useable equity is $680,000.
That $680,000 is what their lender will release without triggering LMI. It is enough to fund the deposit and costs on a serious investment property purchase, which we will work through in section six.
We have seen Castle Hill homes come in 5 to 10 percent below what the owners expected, and we have also seen Kellyville properties come in 8 percent above. Either way, you need the real number before you plan.
The two ways to use equity: cash out vs separate loan
There are two common ways to turn your equity into investment funds. The structure you choose will affect your tax position, your flexibility, and how easy it is to sell either property down the track.
| Structure | How it works | Tax outcome | Best for |
|---|---|---|---|
| Cash out top-up | Add the equity to your existing home loan account | Mixed purpose, messy apportionment | Quick refinances, simple cases |
| Separate equity split | Open a brand new loan account against the home | Clean 100% deductible | Almost all investment plays |
Option 1: Cash out and increase your existing loan
You go back to your current lender (or a new one if you refinance). They top up your home loan by, say, $225,000. That money lands in your offset or transaction account. You then use it as the deposit for your investment property. The investment property itself sits on a separate loan for the remaining 80 percent.
This is simple to arrange and the cheapest in terms of setup fees. The downside is that the $225,000 sits inside your home loan, mixed in with the original $640,000. From a tax perspective, that mixing is messy and we will explain why later in this guide.
Option 2: Set up a separate equity loan (split)
You ask your lender to create a brand new loan account, secured against your home, for exactly the amount you want to release. In our Castle Hill family's case, that would be a $225,000 split. Your original $640,000 home loan stays untouched. The new $225,000 sits on its own loan account. You then draw it down to pay the deposit and costs on the investment.
This is what almost every accountant prefers, and it is what we structure for most RyRo clients. The reason is straightforward: the new loan is being used entirely for investment purposes, so the interest is fully tax-deductible. There is no mixing, no apportionment, no risk of the tax office questioning your deductions. Our home equity service handles the structure end to end.
Why most brokers recommend separate loans for investment
The tax rule is simple: the deductibility of interest is determined by the purpose of the borrowed funds, not by the security on the loan. If you borrow $225,000 to buy an investment property, the interest on that $225,000 is deductible against your investment income, even if the loan is secured against your owner-occupied home.
Where it gets messy is when you mix borrowed money on the same loan account.
Imagine you top up your existing home loan from $640,000 to $865,000, then use the extra $225,000 for an investment deposit. Your loan now contains both:
- $640,000 of "owner-occupied" debt (not deductible)
- $225,000 of "investment" debt (deductible)
Every repayment you make has to be apportioned between the two. Every redraw further complicates it. The ATO has been clear that if you cannot prove the purpose of every dollar borrowed, they will not let you claim the deduction.
By contrast, a clean split keeps the books straightforward:
- Loan 1: $640,000 secured against the home. Personal debt. Interest not deductible.
- Loan 2: $225,000 secured against the home. Used 100 percent for the investment. Interest fully deductible.
- Loan 3: $680,000 secured against the investment property. Used to buy the rest of the investment. Interest fully deductible.
Three loans, three clear purposes, three clean tax outcomes. This is also where strategies like debt recycling for Hills District homeowners can supercharge results over a 10-year horizon.
How to structure the deposit for an investment property
Continuing with our Castle Hill family. They want to buy an $850,000 investment unit in a growth corridor of Sydney. Their funding map looks like this.
Investment property: $850,000 purchase price
Costs they need to cover upfront:
- 20 percent deposit: $170,000
- Stamp duty (NSW investor rate on $850k): about $33,500
- Conveyancing, building and pest, lender fees: about $3,500
- Loan establishment costs and buffer: about $5,000
- LMI: $0 (because they are putting in a 20 percent deposit)
- Settlement adjustments (rates, water): about $1,500
Total upfront cash needed: about $213,500. Round up to $225,000 to keep a buffer. Sanity-check stamp duty on your own purchase with our NSW stamp duty calculator.
Where does that $225,000 come from?
It comes from the new $225,000 equity loan secured against their Castle Hill home. They never touch their savings, super, or offset.
What's the loan on the investment property itself?
It is a brand new investment loan of $680,000, secured by the investment property. That's the remaining 80 percent of the $850,000 purchase price.
Total debt the family now carries
| Loan | Security | Balance | Tax treatment |
|---|---|---|---|
| Home loan | Castle Hill home | $640,000 | Personal, not deductible |
| Equity loan | Castle Hill home | $225,000 | Investment, deductible |
| Investment loan | Investment property | $680,000 | Investment, deductible |
| Total | $1,545,000 |
The structure feels heavy until you remember the assets: a $1.65 million home plus an $850,000 investment property. Total assets of $2.5 million against $1.545 million of debt. That is a 62 percent loan-to-value ratio across the portfolio, which is well within the bank's comfort zone and yours.

Choosing the right second property: yield vs growth
This is where Hills District buyers often get stuck. Your home grew fast because the Hills District is a strong growth market. The instinct is to buy another Hills District property. The problem is that high growth often comes with lower rental yields, and the cash flow has to make sense from day one.
Most Hills District homes yield 2.4 percent to 3.0 percent gross. On an $850,000 property, that is only $20,400 to $25,500 in annual rent. After interest, rates, insurance, management and maintenance, you will be running a sizeable cash shortfall every month.
Some clients are comfortable with that shortfall because they are betting on capital growth and the tax benefits of negative gearing in 2026. Others want to buy in slightly higher yield areas to keep cash flow neutral or positive.
Higher-yield Sydney suburbs to consider in 2026:
| Area | Gross yield range |
|---|---|
| Mount Druitt, Blacktown, Doonside | 4.0% to 5.0% |
| Penrith, St Marys, Werrington | 4.0% to 4.8% |
| Campbelltown, Minto, Macquarie Fields | 4.2% to 5.5% |
| Central Coast (Tuggerah, Wyong, Lake Haven) | 4.5% to 6.0% |
If you are open to going outside Sydney, regional NSW and even Queensland can deliver 5.5 percent to 7.0 percent yields, though growth is harder to predict.
The right choice depends on your cash flow position, your borrowing capacity, and how much short-term pain you can absorb. A Sydney investment loans specialist will walk you through the maths before you commit.
What lenders actually look at for investment property loans
When you apply for an investment loan in 2026, lenders are looking at three things, in this order:
1. Serviceability
Lenders run your numbers through an assessment rate that is currently 3 percent above your actual rate. So if your investment loan is at 6.20 percent, they'll assess it at 9.20 percent. They will assess your home loan the same way. Then they add up all your living expenses, dependent costs, and any other commitments.
Rental income counts, but lenders only use 75 to 80 percent of expected rent. They assume you will have vacancies, repairs and management fees.
This is why borrowing capacity for investors is much tighter than people expect. Two dual-income Hills District families with similar pay packets can end up with very different borrowing capacities depending on their kids, their car loans, and the lender they apply with.
2. Deposit and LVR
For investment loans, almost every lender prefers an LVR of 80 percent or lower. You can go higher with LMI, but the interest rate margins also go up.
3. Loan structure and exit strategy
Lenders are paying more attention to how you plan to repay the debt over the long term. If you are 50 years old applying for a 30-year loan, expect questions about retirement income and downsizing plans.
If any of this is making you nervous, the easiest fix is to get a pre-assessment done before you start house-hunting. A pre-assessment costs you nothing and tells you exactly how much each major lender will lend you. Book a free strategy call to start one.
Tax implications you need to plan for
We are not accountants and this is general information only, but here are the major moving parts to discuss with your tax adviser.
- Interest deductibility. Interest on the loan used to buy the investment property (both the $225,000 equity loan and the $680,000 investment loan in our example) is deductible against the rental income. If you have a tax loss for the year because deductions exceed rent, that loss reduces your other taxable income. This is negative gearing in plain English.
- Depreciation. Get a quantity surveyor's depreciation schedule done. On a newer unit, depreciation can add $8,000 to $15,000 of non-cash deductions in the first few years. On older properties built before 1987, the deduction is more limited.
- Capital Gains Tax. When you sell the investment, you will pay CGT on the gain. Hold the property for more than 12 months and you get a 50 percent CGT discount as an individual. If you bought the property in a trust or company, the CGT rules differ. Read our guide on buying property in a trust before you decide on ownership structure.
- Land tax. NSW land tax kicks in when the unimproved land value of your investment portfolio (excluding your main residence) exceeds the threshold. In 2026 the threshold is around $1.075 million. One investment unit in Sydney is usually fine. Two or three Sydney properties and you will be paying land tax annually.
- Negative gearing legislation. There is ongoing political noise about reforming negative gearing in Australia. As of May 2026, the rules are unchanged. Build your numbers so that the property would still work if negative gearing benefits were reduced or removed in future.

Quick answers
Frequently asked questions
The quickest way to estimate is to take your current property value and multiply by 0.80, then subtract what you currently owe. For a typical Castle Hill or Bella Vista home bought between 2017 and 2020, you are likely looking at $500,000 to $800,000 of useable equity in 2026. Kellyville and Beaumont Hills homes typically sit a little lower, between $350,000 and $600,000. The only way to get a confirmed number is to order a valuation. Most banks will do a free desktop valuation for existing customers, and an upgrade to a full valuation costs nothing more if you go to formal application.
Useable equity is the part of your home equity that a lender will actually release to you without charging Lenders Mortgage Insurance. The formula is 80 percent of your property's value, minus your current loan balance. If your Hills District home is worth $1.65 million and you owe $640,000, your useable equity is $1.32 million minus $640,000, which equals $680,000. Total equity (property value minus loan balance) is always higher than useable equity, but lenders draw the line at 80 percent for risk reasons.
No, not without paying LMI. Most lenders cap equity releases at 80 percent of your home's value. You can sometimes go to 85 percent or 90 percent if you accept LMI on the additional borrowing, but the LMI premium on equity releases is often more expensive than LMI on a fresh purchase. Most RyRo clients stop at 80 percent so they keep a buffer for future moves, like renovations, a second investment or helping their kids buy. If you want to push higher, we can model the LMI cost against your expected investment returns.
Technically no, you do not need to put down any of your own cash savings. The equity itself becomes the deposit. In our worked example, the family released $225,000 from their Castle Hill home, which covered the 20 percent deposit plus all costs on the $850,000 investment. Their bank account did not move. That said, most lenders want to see some genuine savings (3 percent to 5 percent of the new purchase) sitting in an account for at least three months, just to demonstrate that you can save. A broker can structure around this if cash savings are tight.
Keep them separate, in almost every case. Cross-collateralisation means one lender holds security over both your home and the investment property. It feels simpler, but it makes it much harder to sell either property later. If you sell the investment, the lender can force you to use the proceeds to reduce the home loan. If your home value drops, both properties get re-assessed. The cleaner structure is an equity loan against your home, plus a stand-alone investment loan against the new property. That way each property is independent and you can sell, refinance or restructure either one without touching the other.
It depends on your cash flow tolerance. A break-even position usually requires a gross yield of 5.0 percent to 5.5 percent at current interest rates. Below that, you will be tipping money in each month, which is fine if you can afford it and you are targeting capital growth. Above that, the property may be cash-flow positive after expenses. Sydney inner-ring properties rarely yield above 3.5 percent. If you want positive cash flow, you usually have to look at outer Sydney, the Central Coast, or regional Australia. Most investors blend the two, accepting some negative gearing in growth areas.
A refinance means moving your entire home loan to a new lender, usually for a better rate or different features. An equity loan (sometimes called an equity release or top-up) means adding a new, separate loan account against your existing security, usually with your current lender. You can do both at once, refinancing to a better lender and releasing equity in the same application. For most investment plays, the equity release is what matters. The refinance is optional and depends on whether your current lender's rates are still competitive.
Not if you stay under 80 percent LVR on both your home loan and your investment loan. In our worked Castle Hill example, the family's home loan ends up at $865,000 against a $1.65 million property (52 percent LVR), and their investment loan is $680,000 against an $850,000 property (80 percent LVR). Neither triggers LMI. If you push either loan above 80 percent, LMI applies on the portion above 80 percent. On an investment loan, LMI can add $10,000 to $25,000 to your costs, so it's worth structuring carefully to avoid it where you can.
Yes. Many Hills District clients buy in Queensland, Victoria or regional NSW where yields are higher. The structure is the same: release equity against your Sydney home, use it as deposit for the interstate property, with a separate investment loan secured against the new property. Be aware of state-based differences in stamp duty, land tax, and tenancy laws. Queensland and Victoria have land tax thresholds that work differently to NSW, so if you already own NSW investment property, an interstate purchase can help you spread the land tax load.
From the moment you contact a broker to having funds available, allow four to six weeks. The valuation and credit assessment typically take one to two weeks, formal approval another one to two weeks, and document signing and settlement of the new loan account a further one to two weeks. If you are buying an investment property at the same time, your offer should ideally be conditional on finance with a 21 or 28 day finance clause. We often pre-approve the equity release first, then go shopping for the property, so you can move with confidence at auction or on a private sale.
