Commercial property loan security is usually assessed using two main factors
The strength and suitability of the property security
Lenders usually want a first registered mortgage over the commercial property. They assess whether the asset is standard, marketable, and strong enough to support the requested loan.
ASSET BASED SECURITY
The strength of the borrower and supporting parties
Where the borrower is a company or trust, lenders often want guarantees from directors or related parties, and in some cases they may ask for additional security property as further support.
BORROWER SUPPORTCommon types of security lenders may require
Not every deal needs every item, but these are commonly seen in commercial lending
-
First mortgage over the commercial property Most common
-
Director or personal guarantees Often required
-
Additional security property or collateral Sometimes required
For example, if a company is purchasing a commercial property worth $1,000,000, the lender may take a mortgage over that property and also ask the directors to provide guarantees if the company is the borrowing entity.

Types of security lenders commonly ask for
Commercial lenders can require one or more forms of security depending on the borrower and transaction. They commonly review:
Mortgage over the commercial property- Director or personal guarantees
- Additional residential or commercial property security
- General security over business assets where relevant
- Cash backed support or other collateral in specific cases
The stronger the property and the borrower, the less likely the lender may be to ask for extra supporting security.
When extra security may be required
Additional security becomes more likely when the transaction carries more risk. Important factors include:
Higher loan to value ratio- Specialised or harder to sell property
- Weaker financial position or limited trading history
If the lender sees more risk than normal, they may ask for more than just the standard mortgage over the property being purchased.
How security is commonly structured
Security arrangements can vary widely in commercial lending.
Typical structures include:
Standard Security
Property mortgage only
Common for stronger lower risk deals
Supported Security
Mortgage plus guarantees
Common when borrowing via company or trust
Enhanced Security
Extra collateral added
Used where the lender wants more support
Not every commercial property loan needs complex security, but many lenders still prefer multiple layers of support when the borrower is not personally borrowing in their own name.
Common problems borrowers face
Many borrowers assume the property alone will always be enough security, but lenders often assess the full structure of the deal before deciding what support is required.
Insufficient Security Coverage
If the property does not provide enough support at the requested loan amount, the lender may reduce the loan or ask for extra security.
Possible solutions include:
-
Reducing the leverage
-
Offering another property as support
-
Strengthening the overall structure of the deal
Unexpected Guarantee Requirements
Borrowers using companies or trusts are often surprised when lenders ask directors or related parties to guarantee the loan.
This is a common part of commercial lending rather than an unusual exception.
Specialised Property Risk
If the property is specialised or harder to sell, the lender may want more comfort in the form of lower leverage or extra supporting security.
Standard office, retail, and industrial assets are often easier to fund than niche property types.
Applying With The Wrong Lender
Different lenders have very different security policies for commercial property loans.
Using a lender that understands your structure and property type can materially improve approval chances.
