Quick answer: A useful starting estimate is: property value × target total LVR − existing secured debt. For example, a $1.5m property with $650k already secured against it has $400k of mathematical headroom at 70% total LVR. This is not an approval amount; valuation, purpose, lender policy, borrower risk and exit still apply.

Questions behind this page
- Do lenders lend against equity or property value?
- How much can I borrow against my property for business?
The formula
Indicative additional security capacity = property value × target total LVR − existing secured debt.
Run more than one LVR rather than assuming the maximum. Our calculator shows 65%, 70% and 75% scenarios because the right ceiling depends on the transaction and lender.
Example
Property value: $2,000,000
Existing secured debt: $850,000
At 65% total LVR, total secured debt would be $1,300,000, leaving $450,000 of mathematical headroom.
At 70%, the headroom would be $550,000.
At 75%, it would be $650,000.
Those figures only describe security capacity. They do not prove that any lender will offer those amounts.
Why approved borrowing can be lower
A valuation can come in below the owner's estimate. A lender can cap leverage for a particular property type, location, loan purpose or risk profile. A second mortgage may also have a different appetite from first-ranking finance.
The exit strategy can be as important as the LVR for short-term private finance.
