How much can I borrow against my home to buy an investment property? Ask Margaret

Dear Margaret,

I have a mortgage of $420,000 and my home is worth $750,000.

Is my equity $330,000 and would the bank theoretically allow me to borrow this amount and buy an investment property to rent?

Does your wage dictate the amount the bank will lend for the investment loan, or does it just lend you the $330,000 if you indicate that the rent would cover the loan?

Thanks,

PC

Hi PC, 

The bank allows you to borrow up to 80% of the entire value of your property without lender’s mortgage insurance (LMI) applying, or up to 95% (depending upon the lender) of the value with LMI.

LMI is an insurance policy to protect the bank in the event that you default and a forced sale does not provide enough proceeds to cover your outstanding debt. While it’s a policy for the bank, you pay the premium which, depending on the loan amount and how close to 95% you get, can run to thousands and thousands of dollars.

In your case, your total property is worth $750,000 and so, at 80% of that total value, you can borrow $600,000 all up. As you only owe $420,000, this means that you still have $180,000 of potentially available borrowings. Now remember that this potentially available borrowing is on the existing property – once you find a property to buy and add it to the mix, you can borrow up to 80% against that property, too! So that means that whatever you have left as potential available borrowings on your current home will cover the 20% deposit.

Given that you have $180,000, technically it’s enough to cover the 20% deposit on $900,000 of additional property. As you will have stamp duties and costs in there too, you can probably expect to easily be able to secure a further $800,000 of property with the current equity you have in your own home, and cover all costs too.

I say ‘potentially available borrowing’ as equity is not the only criteria for borrowing.

You also need to be able to demonstrate the ability to service a debt. Your income, plus any rent from the property you want to buy, will be considered and a formula used to determine if you can afford to meet your daily living expenses plus the cost of your total borrowings. 

Most lender’s will accept the total amount of PAYG income you earn, self-employed income, as long as you can prove it over two years, and 80% of the actual or projected rent return. Some lenders will consider things like family allowance payments and child support, some investment income and other income – each lender is different. 

In considering your total liabilities, banks will take into account current payments on all loans and credit cards, commitment to child support if any, and the future repayments on the new loan being applied for. Usually, they will add a margin to the new loan repayment just to be sure you can Afford any unforeseen interest rate rises.

Regards,

Margaret
