How lenders assess commercial property loans: valuations, tenants and cover ratios

Residential credit assessment is largely a formula; commercial credit assessment is closer to a judgement. Two applications for the same amount against buildings on the same street can land on very different terms, because the lender is pricing the building's income, its tenants, its asset class and its resale story — not just a borrower's payslip. Understanding how that judgement is built is the difference between an application that sails and one that gets ground down at every stage. This piece goes inside the assessment mechanics; for the broader landscape — doc types, GST, the process end to end — start with [our commercial property loan guide](/articles/commercial-finance/commercial-property-loans). As ever, this is general information, not advice.
The valuation: where the deal is really decided
Commercial valuations are specialist work, and they anchor everything: the lender lends against the valuation, not the contract price. Valuers typically lean on two approaches:
- Income capitalisation — the property's sustainable net income divided by a market-derived capitalisation rate. This is the workhorse for tenanted investment property, and it means the lease drives the value: if the valuer judges the passing rent to be above market, or discounts income for likely vacancy, the valuation falls even if comparable buildings sold well
- Comparable sales — recent sales of similar properties, adjusted for differences. This carries more weight for owner-occupied or vacant property, and as a cross-check on the income approach
Commercial valuations take longer and cost more than residential ones — often weeks, with the bill usually the borrower's even if the loan does not proceed — because the valuer is analysing leases, outgoings, market rents and the asset's re-letting and resale prospects, not just inspecting a dwelling. Practical consequence: have every lease, outgoings statement and recent capital-works detail complete and legible before the valuer is appointed. Gaps get filled with conservatism.
The tenancy profile: the income under the microscope
For investment property, the lender's core question is how reliable the income is. Three dimensions dominate:
- Lease length. How much term is contractually locked in, and — for multi-tenant assets — the WALE (weighted average lease expiry). Income secured for years is worth more than income expiring soon, both to the valuer and the credit team
- Tenant strength. A government agency, national brand or listed company is a stronger covenant than a young private business; bank guarantees and rental history strengthen weaker covenants. Related-party leases are scrutinised for market rent and proper documentation
- Vacancy allowance. Assessors rarely take the rent at face value — they commonly shade it or build in a vacancy and re-letting allowance, recognising that commercial vacancies run longer than residential ones and often involve incentives
Where the loan rests almost entirely on this analysis — with no financials behind it — you are in lease-doc territory, which we unpack in our guide to [lease-doc lending](/articles/commercial-finance/lease-doc-commercial-lending). For owner-occupied premises, the tenancy analysis is replaced by analysis of the business itself: its financials, its stability and its capacity to pay, as covered in our guide to [buying a premises for your business](/articles/commercial-finance/buying-business-premises-commercial-loan).
Cover ratios: the arithmetic of comfort
Commercial serviceability is usually expressed as coverage rather than surplus. Two related ideas do the work:
- Interest cover ratio (ICR) — net income divided by the interest bill. Lenders commonly want income to exceed interest with a comfortable margin, and they often test it at an interest rate above the actual rate, so the loan still covers if rates move
- Debt service cover — the same idea including principal repayments, used where the facility amortises
The thresholds vary by lender, asset type and income quality — a strong tenant on a long lease earns a thinner required margin than a specialised asset with a private tenant — so treat any specific ratio quoted online as indicative at best. What matters for your planning: the margin the lender requires, tested at a buffered rate, frequently constrains the loan size before the LVR cap does. Borrowers who back-solve from "the LVR says I can borrow X" are often surprised; the income test gets a veto.
A 15-minute chat is usually enough to map your options — free, no obligation.
LVR by asset type: not all buildings are equal security
Commercial LVR caps are commonly lower than residential, with no LMI to bridge the gap — and within commercial lending, gearing steps down as assets get harder to re-sell:
- Standard assets — offices, industrial units and warehouses, and well-located retail — attract the most generous commercial gearing, industrial having been particularly well-regarded in recent years
- Retail with specific risks — secondary locations or single-purpose configurations — can be treated more cautiously
- Specialised assets — childcare centres, pubs, service stations, medical facilities, purpose-built premises — take the sharpest haircuts. Their value is entangled with the business operating inside them, the buyer pool at resale is thin, and repurposing is expensive, so lenders lend a smaller share of value and look harder at the operator
Location runs through all of it: a metro industrial unit and an identical regional one can be geared differently simply because of the depth of the resale market.
Rate sensitivity, reviews and covenants
Two features of commercial lending catch residential-trained borrowers off guard.
First, interest-rate sensitivity is tested, not assumed away: because cover ratios are calculated at buffered rates, a rise in market rates can shrink what you can borrow — and on interest-only facilities, rate rises flow straight into the cover ratio during the loan, not just at approval.
Second, larger facilities often carry annual reviews and ongoing covenants — obligations that survive settlement. Common examples include maintaining a minimum ICR or maximum LVR, providing updated financials or rent rolls each year, and notifying the lender of major lease changes. A covenant breach does not automatically mean default, but it can trigger repricing, reduced limits or a requirement to reduce debt — and a market-driven valuation fall can cause a breach even when every repayment has been made on time. Read the review and covenant clauses before signing, and ask what happens on breach.
What strengthens an application
The common threads from the credit team's side of the desk:
- Complete, professionally documented leases with clear outgoings recovery, provided upfront
- A sensible gearing request — asking below the theoretical maximum signals buffer and usually earns better pricing
- Demonstrated income beyond the property, even on lease-doc, and clean conduct on existing facilities
- A realistic plan for lease expiries inside the loan term
- Time: allowing commercial timeframes for valuation and assessment rather than forcing a rushed, conservative answer
Talk it through with a broker
Commercial credit appetite differs sharply between lenders — the asset type one bank shades, another specialises in, and the spread in gearing, pricing and covenants is wider than anywhere in residential lending. You can see the range on our [commercial loans page](/loans/commercial-loans), or [get in touch](/contact) and we can match your property and income profile to the lenders most likely to assess it well.
Frequently asked questions
How is a commercial property valuation different from a residential one?
Commercial valuers assess the property as an income-producing asset, typically using income capitalisation — sustainable net rent divided by a market capitalisation rate — cross-checked against comparable sales. They analyse leases, outgoings and re-letting prospects, which is why commercial valuations take longer, often weeks, and cost more, with the fee usually payable even if the loan does not proceed.
What is an interest cover ratio and why does it matter?
It is the property's net income divided by the loan's interest cost — the core serviceability measure in commercial lending. Lenders commonly want income to exceed interest by a comfortable margin, tested at a buffered rate above the actual one. In practice the required cover often limits your loan size before the LVR cap does.
Why do specialised properties like childcare centres or pubs get lower LVRs?
Because their value is tied to the business operating inside them, the pool of potential buyers at resale is thin, and converting them to another use is expensive. Lenders respond by lending a smaller share of the value than they would against standard offices, warehouses or retail, and by looking harder at the strength of the operator.
Do commercial lenders review the loan after settlement?
Larger facilities commonly carry annual reviews and ongoing covenants — such as maintaining minimum interest cover or maximum LVR, and supplying updated financials or rent rolls. A breach can trigger repricing or a requirement to reduce debt even if repayments are on time, so read the review clauses before signing and ask what happens on breach.
How do lenders treat vacancy risk in the assessment?
Conservatively. Assessors rarely take passing rent at face value — they commonly shade it or apply a vacancy and re-letting allowance, because commercial vacancies typically run longer than residential ones and re-letting often involves incentives. Long remaining lease terms, strong tenants and staggered expiries all reduce the discount applied.
What can I do to get a stronger commercial loan outcome?
Provide complete, well-documented leases and financials upfront, request sensible gearing rather than the theoretical maximum, keep conduct clean on existing facilities, and have a plan for any lease expiries during the loan term. Allowing realistic commercial timeframes for valuation and assessment also tends to produce better answers than a rushed process.
