Contaminated land and commercial property loans: what lenders worry about and how to get ahead of it

Contamination makes a commercial property loan harder because clean-up costs and environmental duties can reduce the property’s value and slow any future sale. Lenders don’t automatically refuse these sites, but they want evidence. A preliminary site investigation before you buy, shared with the lender, is usually what turns a worrying unknown into something that can be priced and financed.

Former service stations, mechanical workshops, dry cleaners and factories are often well located and fairly priced, which is exactly why business owners and investors want them. This guide explains how lenders look at them and what to do before you sign.

Why do lenders care about contamination?

A lender’s security is only as good as what the property would sell for if things went wrong. Contamination threatens that in three ways:

• Value. A valuer may reduce the value to reflect investigation and clean-up costs, or decline to value until more is known.
• Saleability. Fewer buyers want a site with a contamination question, so a sale takes longer.
• Liability. Environmental laws can place duties on whoever owns, manages or controls the land. A lender doesn’t want to inherit those duties if it ever has to take possession.

For a commercial property loan, that usually means more questions, a lower share of value advanced, or a requirement for an environmental report before approval.

What does a valuer do when contamination is possible?

Valuers aren’t environmental scientists, and most say so in their reports. When the inspection, the history or the zoning hints at a past industrial use, a valuer will typically do one of three things: value the property on the assumption that it’s free of contamination and flag that assumption clearly; reduce the value to allow for likely investigation or clean-up; or decline to give a firm figure until an environmental report is available.

Each of these lands on the lender’s desk differently. A clearly stated assumption with no evidence to back it often prompts the lender to ask for a report anyway. A reduced value lowers the loan amount. A refusal to value stalls the deal altogether. Supplying an environmental report at the start means the valuer can work from facts rather than assumptions, which tends to produce a firmer, more useful valuation.

Which properties raise questions?

Lenders and valuers usually ask about contamination when a property’s history includes:

Past or current use	Why it’s flagged
Service station or fuel depot	Underground tanks and fuel leaks
Mechanical or panel workshop	Oils, solvents and paints
Dry cleaner	Cleaning solvents that can travel in groundwater
Metal finishing or plating	Heavy metals and chemicals
Printing	Inks and solvents
Manufacturing or chemical storage	Varies with what was made or stored
Former landfill or filled land	Unknown fill material and gases

None of these uses means a site is contaminated. They mean someone should check. If you run a trade business from one of these sites now, such as a mechanic workshop, expect the question when you refinance or borrow against it.

What do the rules say about owners and buyers?

Rules differ between states, so check where your property is. Two examples show the general direction.

Victoria. The EPA’s guide to buying, selling or developing land explains that anyone in management or control of contaminated land must minimise risks to human health and the environment so far as reasonably practicable, and that these duties apply even if you didn’t cause the contamination. It also says landowners have an obligation to disclose known contamination to buyers. It suggests researching past uses, checking resources such as the Priority Sites Register, and considering a Preliminary Site Investigation before you buy if no assessment exists.

NSW. The EPA publishes a record of notices it has issued about significantly contaminated land, including notices requiring investigation and remediation, which buyers and lenders can search. The EPA also says landowners and those responsible for contamination must report it to the EPA.

Councils matter too. The government’s guide to choosing business premises encourages buyers to check with council about zoning, permits and future development, and council records and planning certificates can also reveal what’s known about a site.

What should you do before you buy or borrow?

1. Ask the seller directly what the property has been used for and whether any environmental reports exist. Ask for copies.
2. Search the registers in your state, and check council records.
3. Research the history, using old business listings, aerial photos and neighbours’ memories. A long-closed fuel outlet often leaves traces in the records.
4. Commission a preliminary site investigation if there’s any doubt. It’s far cheaper before settlement than after.
5. Get legal advice on the contract, including any special conditions about contamination and who bears clean-up costs.
6. Share the results with your lender early. A report showing low risk, or a known issue with a costed plan, is much easier to lend against than silence.

If you’re looking at a site with a chequered history and want to know how lenders would view it, tell us about the property before you commit.

How can you still get the deal financed?

Even when contamination is confirmed, deals happen. Common approaches:

• Price it in. The purchase price reflects the clean-up, and the lender lends on the adjusted value.
• Make the seller fix it first. Remediation is a condition of the sale, with evidence before settlement.
• Add other security. Equity in another property can make up for a lower share advanced on the site itself, through a secured business loan over both.
• Use a short-term facility. A private mortgage can fund the purchase while investigation or remediation is completed, then be refinanced once the site has a clean report.

Already own the site and need to refinance?

Owners who have run a workshop or small manufacturing business from their own freehold for years are sometimes caught off guard when a new lender asks about contamination that the original lender never raised. Every lender has its own policy, and a refinance is treated like a fresh application.

Prepare for the question rather than resent it. Gather what you know about how the site was used before you bought it, how you store and dispose of oils, chemicals or solvents, and any council or EPA correspondence. If you’ve had no incidents, say so and show your waste disposal records. If an old tank or pit is on the site, find out its status. A short, factual summary often answers the lender’s concerns without the need for a full investigation.

Illustrative example: a former workshop for a new showroom

Illustrative only. A kitchen and joinery business wants to buy a former mechanical workshop on a busy road for $1.3m to use as a showroom and assembly space. The valuer notes the past use and says they can’t confirm value without environmental information.

The buyer’s solicitor negotiates a contract with time for an investigation. A preliminary site investigation finds localised oil staining near an old pit but no sign of wider contamination. A consultant prices the clean-up of that area, and the seller agrees to a price reduction to cover it.

With the report in hand, the lender completes its assessment on the reduced price and lends against the property, plus a small second mortgage over the owners’ home to make up the difference. The pit is cleaned up and filled during the fit-out, and a year later, with a clean follow-up report, the owners refinance onto a single facility over the showroom alone.

Found the right site but worried about its history? Let’s talk

Older commercial sites are often the best-located, best-value premises around, and plenty of business owners finance them successfully. The trick is to deal with the contamination question before it deals with you. Property-secured loans run from $20k to $5m, on residential or commercial security.

The enquiry takes around 60 seconds, and there’s no credit check when you first enquire. We won’t send your details to a pile of lenders. A real person looks at the site, its history and any reports you have, then calls you to talk it through. Please describe the property’s past use accurately, because that’s what lets us find a lender comfortable with it first time.
