Using equity to invest or buy another home | Home loan guide - NAB

What is equity and useable equity?

Equity is the difference between your home’s market value and what you still owe on your loan.

Property value minus amount owed equals equity.

Lenders usually let you borrow up to 80 percent of your home’s value, less your current loan. This is called useable equity. If you borrow more than 80 percent, you may need lenders mortgage insurance (LMI). For example: If your home is worth $400,000 and your loan is $220,000, 80 percent of value is $320,000, so your useable equity is $100,000.

Step-by-step to use equity as a deposit

Step 1: Estimate your useable equity

You can use the home equity calculator or request a valuation to calculate how much equity you may have available. Existing customers can seamlessly check their equity using the equity calculator in the NAB app.

Step 2: Choose how to access it

Options include a top up to your current loan, a refinance with a new split or a bridging loan if you need to buy before you sell.

Step 3: Apply equity to your deposit

To avoid LMI, you usually need a 20 percent deposit on the new property.

Step 4: Check repayments fit your budget

Use the home loan repayments calculator to estimate how much you’ll need to pay each month for better budgeting.

Buying a second home vs buying an investment property

If you’re using equity to buy another house, your path depends on the purpose. For a second home, lenders assess both loans and your living costs. Timing matters if you’re selling your current place, and a bridging loan may help cover the gap. For an investment property, lenders may count expected rent, and rates can differ.

How much can you borrow?

A simple guide is the rule of four, in which you multiple your useable equity by four to estimate the maximum property purchase price. For example: If your useable equity is $100,000, a target property price could be about $400,000. Remember, your real borrowing power depends on income, expenses, debts, rates and credit history. Test it with the borrowing power calculator, then get pre-approval to move quickly.

Example scenarios

Investment property

Let’s say you want to buy an investment property with useable equity of $100,000 in your existing home. The rule of four suggests $400,000 as your target purchase price. A 20 percent deposit is $80,000, plus about 5 percent for costs, which is roughly $20,000 bringing the total to $100,000.

Next home

Assume you want an $800,000 home but only have $100,000 useable equity. Your options may include selling first, using bridging finance to buy then sell. Alternatively, you could pay LMI to buy with less than 20 percent deposit. A home loan expert will be able to provide clarity on next steps.

Other costs to plan for

Beyond the deposit, plan for stamp duty, conveyancing, building and pest inspections, lender fees, and settlement adjustments. For investors, add property management fees, insurance, maintenance and vacancy buffers.

How to build equity faster

Small changes add up.

  • Put savings in a 100% offset facility.

  • Make extra or more frequent repayments if your loan allows it. Our loan repayments calculator can show you how much time and interest you can potentially save by changing your repayments. First, you’ll need to check if this option is available on your current loan.

  • Consider focused renovations that add value without overcapitalising.

  • Review your rate and structure and compare options. A home loan expert can review your situation and provide clarity on whether it’s worth refinancing.

Have a backup plan

Even if you have plenty of equity, it’s not always a given that you can borrow against it. Your lender will consider several factors including:

  •  your income
  •  your age
  •  any additional debts.

Remember to play it safe. If you don’t have any funds outside your home equity, then it’s risky to use every cent of your useable equity to invest in property.

You should consider having back up funds in case things don’t go to plan. Even if it means you can’t invest for a while, it’s important to keep yourself protected.

Unlocking all your equity to improve your lifestyle or wealth will increase your level of risk. That’s why it’s always a good idea to consider how much lending you take on.

To make sure you have a plan in place, it’s best to speak with an expert. Simply contact one of our home loan experts – they’ll help you figure out the best solution for your situation.
