Quick answer

Before adding a second mortgage or caveat for a business loan, check your existing mortgage: the current balance, whether repayments are up to date and whether the contract requires the first lender to be notified or to consent to further security. Knowing this up front keeps a property-secured loan fast.

Key points

  • Know your first mortgage balance and lender
  • Check whether further security needs consent
  • Arrears on the first mortgage must be disclosed
  • A caveat can be faster where consent is slow

A second mortgage or caveat lets you borrow against equity without touching the loan already on your property. But that existing loan still matters. Its balance determines how much equity is left, its repayment record affects the decision, and its contract may say something about further security. Checking these before you enquire keeps the process fast.

The three things to check

Check Where to find it Why it matters
Current balance and lender Latest statement or online banking Determines remaining equity and LVR
Repayment status Statement or online banking Arrears change the picture
Further security terms Loan contract or mortgage terms Some require notice or consent

Some mortgage contracts say the borrower must not create further security over the property without telling the first lender or getting its consent. Others say nothing. If yours has such a clause, the second lender will plan for it, which might mean notifying the first lender or seeking consent. If consent is slow, a caveat loan may offer a quicker path.

When the clock matters more than the reading, send your enquiry first. It takes about 60 seconds.

Arrears on the first mortgage

If your first mortgage is behind, say so. Arrears affect how a second lender sees the situation, and sometimes the better solution is a refinance or consolidation that clears the arrears. Hiding them only delays things when they appear in statements or searches.

Redraw and offset

If your home loan has a redraw facility or offset account, check what is available. Sometimes a modest need can be met from redraw, although that changes your home loan. Discuss with your accountant whether mixing business use into a home loan affects deductibility.

A worked example (illustrative)

A café owner wants a second mortgage behind her home loan. She checks her loan contract and finds a clause requiring notice to her bank before granting further security. She mentions it in her enquiry, the second lender prepares the notice and the loan proceeds the same day.

Commercial mortgages

Commercial mortgages often have more detailed covenants than home loans, such as limits on further borrowing or requirements to keep certain ratios. Check yours, or ask your bank, before you enquire.

When the first mortgage is with the same family

Sometimes the first mortgage is a private loan from a family member or associate. That loan should be documented, and the second lender will want to understand its terms and whether it is registered. Bring whatever documentation exists.

What lenders will ask for

Most delays come from documents that are not ready when they are asked for. Line these up before you enquire:

  • Latest first mortgage statement
  • Your loan contract or mortgage terms
  • Repayment history
  • Contact details for your first lender

What holds things up

These are the things that most often turn a same-day answer into a three-day one:

  • Undisclosed arrears
  • Consent clauses discovered at the last minute
  • Commercial covenants nobody checked
  • Informal family loans with no paperwork

Terms used in this guide

  • Prepaid interest: interest paid up front for a period, so there are no repayments during that period.
  • Capitalised interest: interest added to the loan balance instead of being paid as you go.
  • Exit: how a short-term loan will be repaid, such as a sale, refinance, large receivable or business cash flow.
  • Guarantor: a person who agrees to repay the loan if the borrower cannot.
  • LVR: loan-to-value ratio: the total of all loans on a property as a percentage of its worth.

Before you accept an offer

  • What are the conditions on this approval, and which are still outstanding?
  • What is the repayment schedule in dollars, not percentages?
  • Can I pay it out early without a penalty?
  • Who do I call if something changes during the term?
  • Is there anything in the documents you would point out to me?

One request before you enquire

The enquiry takes about 60 seconds, and those 60 seconds decide how smoothly everything after it goes. Accurate figures for revenue and the amount, a straight answer about credit history and a clear yes or no on property mean the assessor can move straight to the decision. Guesswork means rework, and rework is the enemy of a 24-hour turnaround.

In a nutshell

  • Know your first mortgage balance and lender
  • Check whether further security needs consent
  • Arrears on the first mortgage must be disclosed
  • A caveat can be faster where consent is slow

Why this can move in hours, not weeks

Here is the usual rhythm. You enquire in about 60 seconds. A person calls, often within minutes during business hours, to confirm the details and the deadline. Statements are shared through a secure link or property details are confirmed. Approval follows, sometimes within 15 minutes and commonly within the hour. Loan documents arrive by email for electronic signing. Once every borrower and guarantor has signed and the conditions are met, funds are released, often the same day or first thing the next business day.

Frequently asked questions

Does my bank need to approve a second mortgage?

Some mortgage contracts require the first lender to be notified or to consent to further security. Many do not. Check your contract.

Where do I find the consent clause?

In your loan contract or mortgage terms, often under further encumbrances or dealings with the property.

What if my first mortgage is in arrears?

Disclose it. Arrears affect the decision, and a refinance or consolidation may be the better answer.

Will my first lender's rate change?

Adding a second mortgage does not usually change your existing loan's terms.
