Due Diligence & Security Risk
In Australian lending, the borrower and the property are assessed separately.
Even where income, savings, and credit history are strong, a loan can be restricted or declined if the property fails due diligence or is classified as higher risk security.
What Is Security Risk?
Security risk refers to the lender’s assessment of:
- resaleability
- legal compliance
- construction quality
- market depth
This assessment exists independently of the borrower.
What Due Diligence Covers
Due diligence typically includes review of:
- zoning and planning compliance
- strata reports and sinking funds
- unapproved structures or renovations
- building condition and materials
- environmental and location factors
Any unresolved issue increases lender risk.
Why Security Risk Matters to Lenders
From a lender’s perspective:
- the property is the final repayment fallback
- poor resaleability increases loss risk
- legal defects reduce enforceability
As a result, lenders may:
- reduce maximum LVR
- exclude certain lenders entirely
- require additional conditions or reports
Common Examples of Elevated Risk
Security risk commonly increases where:
- works are unapproved or undocumented
- strata funds are under-resourced
- properties are specialised or niche
- locations have limited buyer depth
These risks are structural, not negotiable.
