Quick answer
Security cover compares the loan with the worth of the property behind it. LVR, the loan-to-value ratio, is the debt secured on a property divided by its value, shown as a percentage. Lower means more cushion. For a second mortgage, the first mortgage counts in the debt too. You can estimate your own position from your mortgage statement and a sensible view of value.
Key points
- LVR is total secured debt divided by property value.
- Lower LVR means a bigger cushion for the lender.
- For a second mortgage, the first mortgage counts toward the total.
- Equity is the cushion; you can estimate it yourself in a few minutes.
- LVR
- Total secured debt / property value
- Equity
- Value minus debt secured on the property
- Covers
- Residential and commercial property
What is security cover?
It is the cushion between what a loan is and what stands behind it. When a loan is secured by property, the lender takes a registered interest in that property. If things go wrong, the property can be sold to repay the debt. Security cover describes how comfortable that safety net is: how much value sits behind each dollar lent.
business.gov.au describes the basic trade-off in simple terms: debt finance lets you keep ownership, but repayments are required, and loans often need collateral. Property is the most common collateral, and cover is how lenders measure it.
What is LVR?
LVR stands for loan-to-value ratio. The formula is one line:
LVR = total debt secured on the property / value of the property
Shown as a percentage. A property worth 1,000 units with 400 units of total secured debt has an LVR of 40 per cent. The same property with 700 units of debt has an LVR of 70 per cent. Lower means a larger cushion; higher means a thinner one.
The numbers here are purely illustrative. The point is the shape of the sum, which is something you can do yourself with a mortgage statement and a sensible view of value.
How does a second mortgage change the sum?
The new loan sits behind an existing one. The security cover is measured on everything secured against the property, so the first mortgage and the new loan together are divided by value.
| Step | Example (illustrative units) |
|---|---|
| Property value (estimate) | 1,000 |
| First mortgage balance | 450 |
| New loan under discussion | 150 |
| Total secured debt | 600 |
| LVR | 60 per cent |
| Remaining equity after both | 400 |
That is why the first mortgage statement features so heavily in the paperwork for second-position loans; see second mortgage and caveat paperwork.
What is equity, and how do I estimate mine?
Equity is the property’s value minus the debt secured on it. To estimate yours:
- Find a sensible value. Recent sales of similar properties nearby are a reasonable guide. Be conservative; optimism does not change what the lender concludes.
- Find the mortgage balance. From your latest statement, not from memory.
- Subtract. The remainder is a rough measure of equity.
This is an estimate for your planning only. The lender forms its own view of worth and decides how the loan is structured, so treat your number as a starting point for the conversation, not a promise.
Illustrative example. An engineering workshop owner owns a small industrial unit. A sensible estimate of its value is 800 units, and the mortgage statement shows 300 outstanding. Equity is roughly 500. The owner mentions this on the enquiry form and the specialist can immediately see which structures might fit.
Does it matter whether the property is residential or commercial?
Both are accepted as security. The difference is in the file around them. Commercial property usually brings in lease details and information about tenants, since the income from the property is part of its story. Residential property tends to be simpler to document. Neither is better or worse as a concept; each has its own paperwork. The property-secured pack lists what to gather for each.
Is security the whole story?
No, and owners often overestimate its pull. Strong cover helps. It can balance a thin trading history or a rough patch. But the assessor still reads the business, the statements and the borrower, and a file with excellent cover and unexplained statements will still draw questions. The seven questions in what lenders look for apply to secured files as well, with security as an eighth.
What happens after the security is agreed?
The legal steps follow: documents are signed, the security is registered and funds are released. The sequence is explained in settlement steps for property security.
What are the common mistakes with equity?
- Using an asking price as a value. A price someone hopes to get is not the same as what a property is worth to a lender. Use recent comparable sales and be conservative.
- Forgetting a debt. A second charge, a line of credit secured on the same property or an old caveat all count toward the total secured debt.
- Assuming equity is all available. Lenders leave a margin, so the full gap between value and debt is never the full borrowing capacity.
- Counting the same equity twice. If two lenders are asked about the same property, the first loan’s equity is not available again.
How do I get a sensible estimate of value?
Look at recent sales of similar properties in the same area: size, type, condition and position. For residential property, public sales listings give a reasonable picture. For commercial property, the lease income and the type of tenant matter alongside the building itself, and local agents or valuers are the usual sources of a view. Write down your figure, the date and what you based it on. Keep the estimate low enough to defend and you will not be disappointed by the lender’s own view.
Ready to lodge?
If you have an idea of your equity, lodge a free enquiry and say that property is involved. It takes about a minute, leaves your credit file alone at this stage, and goes to one person who reads it, not to a crowd of lenders.
Give honest figures for the property: the state, the type, roughly what it is worth and what is owed. The more accurate the form, the more useful the first call, and the property documents in your pack will be ready when the specialist asks.
Frequently asked questions
What does LVR stand for?
Loan-to-value ratio. It is the total debt secured against a property divided by the property's value, usually written as a percentage.
How do I estimate my own equity?
Take a sensible estimate of the property's value, subtract the balance of any mortgages on it, and the remainder is equity. Use recent comparable sales as a guide, and be conservative; the lender forms its own view.
Does a second mortgage count the first mortgage?
Yes. The security cover is judged on all debts secured on the property, so the first mortgage and the new loan together are measured against value.
Why does commercial property differ from residential?
The way a lender views the two can differ, and commercial property often brings leases and tenant information into the file. Both are accepted as security.
Does more equity guarantee approval?
No. Security is one part of the file. The business's trading and the borrower's situation still matter, but good cover can balance a weaker area.
