Finance Overview

Current rates, LVRs and loan structures for commercial office loans

Commercial office loans finance the purchase of existing office property across Australia, from whole CBD buildings and suburban office parks to individual strata suites and professional rooms.

Office property finance rates currently sit at 6.60% - 9.95% p.a. for established, tenanted offices with quality covenants. We typically see rates at the upper end of that range for older suburban offices, shorter lease profiles or higher-LVR positions, while 6.60% is generally reserved for prime CBD and A-grade offices with blue-chip or government tenants on long leases. Owner-occupiers buying their own premises can often access up to 80% LVR, with investors and strata suites typically a step below.

What we finance

Types of office property we finance

We arrange commercial office loans across the full range of office real estate in Australia, from whole CBD towers and suburban office parks to individual strata suites and professional rooms. Our 60+ specialist lender panel covers every office property type and ownership structure below, for both owner-occupiers and investors.

Prime A-grade CBD office tower in an Australian capital city financed by Smart Business Plans

CBD & A-grade office towers

Whole buildings and floors in prime CBD and metropolitan locations, leased to blue-chip, ASX-listed or government tenants on long-term leases. Strong tenant covenants and a healthy WALE put these at the sharpest end of office pricing, with owner-occupiers able to access up to 80% LVR. This is the asset class lenders compete hardest to fund.

Suburban office park and business centre with on-site parking financed by Smart Business Plans

Suburban offices & office parks

B-grade suburban offices, business parks and standalone commercial buildings, the workhorse of owner-occupier office finance. These still secure strong terms, with the assessment leaning on location, tenant quality and parking ratios. Sites with more than four spaces per 100 sqm of net lettable area consistently present better, as tenants increasingly prioritise staff parking.

Property owner outside a strata-titled office suite within a multi-tenant Australian professional building

Strata suites & professional rooms

Individual strata-titled office suites and professional rooms, the most common entry point for first-time commercial buyers and SMEs buying their own premises. Lenders look closely at the body corporate finances, sinking fund and strata fees. For consulting and medical suites specifically, specialist healthcare lenders often offer stronger terms again.

Our commercial lending marketplace

Over 60 business lenders. One specialist broker.

Our lending panel includes major banks, regional banks, specialist non-bank lenders, and private credit providers, including lenders who only deal through accredited brokers directly.

Who we finance

Owner-occupier, investor or SMSF buyer: which office loan pathway suits you?

Office buyers typically fall into one of three pathways, and each shapes your lender pool, deposit position and structuring. You may be an owner-occupier buying premises to run your business from, an investor chasing yield from a leased office, or buying an office through your self-managed super fund. All three are ways of acquiring an existing office; what changes is how lenders assess the deal.

Comparison criteria Pathway 01 Owner-occupier Pathway 02 Investor Pathway 03 SMSF buyer
What drives the application Buying premises to run your business from, where the office is owner-occupied rather than leased to a third party, often making the purchase competitive against years of rent Acquiring a leased office for income, where the focus is yield, the strength of the sitting tenant and the security their lease provides over the loan term Purchasing an office inside your super fund, commonly to lease back to your own business at market rent, holding the asset in a tax-advantaged structure for retirement
What lenders assess Your business trading position and serviceability, the strength of the premises, and your time in business, owner-occupiers attract the sharpest LVRs and pricing Tenant covenant strength and WALE, the lease structure, building grade and location, and how much of the rental income the lender will count toward serviceability The fund's position and contributions, the lease to the related party at arm's length, and the office itself, with LVR more conservative than a standard purchase
Typical LVR Up to 80% for strong owner-occupiers on prime or A-grade premises Generally a step below owner-occupier, with the sitting tenant and WALE driving where it lands More conservative again, typically around 65% for an office held in super
Best suited for Business owners ready to stop renting and buy their own premises, from a single suite to a whole building First-time and experienced commercial investors wanting a leased office with a clear income profile under one title Business owners with an established SMSF who want to own their premises through super and lease it back to the business

Am I eligible

What lenders look for in commercial office loan applications

Eligibility for commercial office loans turns on more than your credit history alone. Lenders underwrite both the property and the borrower position, so your background, the office itself, and the strength of the income stream all factor into the assessment. Five factors drive most decisions, and the quick check gives an indicative view of where you sit across each one.

  • 01
    Deposit position Most office lenders expect a 20% - 40% deposit, with owner-occupiers on prime premises accessing the lower end. First-time investors, strata suites or weaker-covenant offices typically need a stronger deposit alongside cleaner financials.
  • 02
    Borrower profile Owner-occupier deals lean on your business's trading position and the fit of the premises. Investor deals draw on commercial property experience and balance sheet strength. SMSF buyers are assessed on the fund's position and the arm's-length lease back to the business.
  • 03
    Building grade and location Building grade, location and parking all factor into valuation and lender appetite. Prime and A-grade offices in established CBD and metropolitan locations attract the sharpest terms, while strong parking ratios, above four spaces per 100 sqm, lift suburban offices in lenders' eyes.
  • 04
    Tenant covenant and WALE For investors, the tenant covenant and WALE are the single biggest drivers, a long lease to a government or blue-chip tenant unlocks the best terms. For owner-occupiers, it is your business's serviceability and how well the office suits how you operate.
  • 05
    Compliance and credit history Clean credit history with no recent defaults, court judgments or current ATO arrears. For offices specifically, building compliance matters too, fire safety, disability access and any cladding issues can stall an otherwise straightforward deal until resolved.

Quick eligibility check

Five questions, takes about 30 seconds

Question 1 of 5

Do you have a 20% - 40% deposit for your office purchase?

This can be cash, equity in another property, or SMSF funds. First-time investors or strata suites typically need more.

How are you buying the office?

Different buyer types have different lender pools and assessment focus.

What's your borrower profile?

Lenders weigh your trading or investment background as a primary credit factor.

Where is the office located, and what grade?

Location and building grade shape lender appetite and pricing materially.

What's the tenancy or use position?

Income stream stability is what lenders use to assess serviceability.

How it works

How commercial office loans work in Australia

A commercial office loan is a commercial mortgage secured against an office property, whether a whole CBD building, a suburban office, or a strata-titled suite. It is a discipline of its own within commercial property finance, with a different lender pool and different metrics than industrial property finance or retail commercial lending.

A commercial office loan is three assessments running in parallel

When we write an office property deal, the lender runs three assessments in parallel, not one. Two offices at the same purchase price can attract very different terms depending on lease profile, tenant covenant or borrower profile, even when the building looks identical on paper. How each assessment is presented determines the terms you actually win.

  • The property

    Sets the ceiling

    The lender's valuation determines maximum exposure. Building grade, location, floorplate, parking ratio and energy rating all factor into what can be lent.

  • The income stream

    Determines your position

    How close to that ceiling you actually get. Tenant covenant and WALE for investors, or business serviceability and operational fit for owner-occupiers.

  • The borrower

    Decides who competes

    Your profile shapes which lenders compete for the deal. Specialist office lenders, generalist commercial real estate lenders, non-bank specialists, and SME business banks each play different roles.

Broker insight

The lease profile, and the cost of finding out late

On an investment office, the lease profile can move your LVR more than your balance sheet does.

We see buyers move on a leased office because the yield looks strong, without reading the lease and tenancy schedule closely first. The rent is healthy, the price is right, the lender's preliminary indication is supportive. Then the valuer reviews the lease, flags that the WALE is under two years or the tenant holds an early break option, and the lender re-prices the deal, cutting the LVR and sometimes the loan amount.

By that point the deposit is committed, the LVR offer has been cut, and the deal economics have shifted. Some buyers walk away. Others accept terms they would not have accepted at the start. The buyers who avoid this are the ones who get the lease and tenancy schedule reviewed before they sign anything.

A long lease to a strong tenant is the single biggest lever on an investment office. A short remaining term, an early break clause, a make-good liability or an under-market rent review can all quietly reshape what a lender will offer. The buyers who win better terms are the ones who arrive at the lender already understanding their lease.

"On office deals, the buyers who get the best terms aren't always the ones with the strongest balance sheets. They're the ones who understand their lease and WALE before they sign anything."

Worked example

How the same office looks under a strong versus short lease profile

A $5M office investment purchase. Same building, same location, same purchase price. The only variable is the lease profile, a long lease to a strong tenant versus a short remaining term. The numbers below are illustrative only and vary by deal, lender and specific tenant.

Strong lease profile 5+ year WALE, government or blue-chip tenant, fixed reviews. Mainstream lender pool.
$3.75M lending · 75% LVR
Short lease profile Under 2 year WALE, early break option, weaker covenant. Narrower lender pool.
$3.25M · 65% LVR
−$500K

What drives the $500K reduction?

  • LVR cap by lease strength Lenders trim LVR when the WALE is short or the tenant covenant is weaker, reflecting the risk of vacancy and re-letting cost if the tenant leaves before the loan is comfortably serviced from rent.
  • Lender pool restriction Mainstream lenders compete hardest for offices with long leases to strong tenants. A short WALE narrows the field toward lenders comfortable pricing re-letting risk, which typically lifts the rate.
  • Income shading on serviceability With a short remaining term, lenders shade the rental income harder when testing serviceability, or look through to a vacant-possession scenario, both of which reduce how much they will advance.

Numbers are illustrative for clarity. Real LVR and lender appetite depend on the specific tenant, lease terms, building and your borrower profile. A short WALE is not a dealbreaker, and we often secure strong terms by matching the deal to a lender comfortable with the lease profile.

Common mistakes

6 mistakes that cost the most on commercial office loans

These six come up again and again on office deals. Each one can cost tens of thousands of dollars or stall an otherwise clean purchase. Here is the mistake, what it costs, and what to do instead.

Six common commercial office loan mistakes, what each one costs, and the fix.
The mistake What it costs Do this instead
Using the face rent on a leased office to estimate your borrowing power An approval well below expectation once the rent is shaded and a short WALE is discounted Run the shaded income and check the WALE before you make an offer
Making an offer before reading the lease and tenancy schedule closely A cut to your LVR at valuation when a short WALE or early break option surfaces Get the lease and WALE reviewed before you sign anything, not after
Overlooking the parking ratio on a suburban office or office park A weaker valuation and harder re-letting, since tenants increasingly prioritise staff parking Check the parking ratio early, above four spaces per 100 sqm presents best
Ignoring the body corporate health on a strata-titled office suite A stalled or declined application when the scheme has poor financials or major works pending Review the strata records and sinking fund early, we flag lender concerns while there is time
Taking the deal straight to your bank and accepting its first assessment A conservative offer from a lender that does not actively price office covenant and WALE Match the deal to the specialist lenders who compete hardest for office
Sizing your deposit to the headline maximum LVR rather than your likely one A funding gap at settlement when the actual LVR lands below the advertised ceiling Size your deposit to the lender’s likely LVR for your profile, not the maximum

Discuss this scenario

Indicative estimate only, not a loan offer or financial advice. Income is assessed at a rate above the one you enter and against a minimum interest cover, the way lenders stress-test serviceability, so your real capacity depends on full lender assessment.

Lender comparison

Who lends on commercial office property, and how they differ

Office finance is not a single market. The same purchase can be priced very differently depending on which type of lender writes it. Here is how the main lender categories approach commercial office loans, and where each one tends to win.

What to compare Big 4 & major banks Specialist & non-bank lenders Private capital
Typical LVR Up to 80% for owner-occupiers on prime offices, a little lower for investors Competitive on offices the majors find harder, often matching on LVR with more flexible criteria More conservative, commonly 50% to 65%, with the deal speed mattering more than the last few points of LVR
Rate posture Sharpest pricing for strong, long-leased offices with quality tenants and clean borrowers A modest premium over the majors, priced for the specific lease and covenant rather than a rigid box Highest cost of the three, reflecting speed, flexibility and appetite for the harder deals
Tenant and lease appetite Prefer a long WALE and a strong covenant, government or blue-chip tenants assessed most favourably Comfortable with shorter WALE, mid-tier tenants and the odd vacancy, where the majors hesitate Will look at vacant or transitional offices and repositioning plays the banks will not fund
Best suited for Owner-occupiers and investors with a clean, well-leased office and straightforward serviceability Deals just outside bank criteria, first-time buyers, strata suites and shorter-lease offices Time-critical purchases, short-term positions, and offices being repositioned or re-leased
Typical speed Slower, with fuller documentation and a more rigid credit process Faster than the majors, with credit teams that engage directly on the deal Fastest, with settlement in 14-26 days achievable where the deal warrants it

FAQs

Commercial office loan questions, answered

The questions buyers most often ask me about financing an office in Australia.

Eligibility and deal qualification

What types of office property can be financed?

Commercial office loans finance the full range of office property: whole CBD and A-grade office towers, suburban offices, office parks, individual strata-titled suites, and professional rooms. I arrange finance across all of these, and each one carries different lender appetite.

In practice, well-leased prime and A-grade offices sit at the top of the LVR ladder with the full lender pool competing. Suburban offices and strata suites are still strongly supported, with the assessment leaning more on location, parking and the strength of the tenant. For consulting and medical suites specifically, specialist healthcare lenders often offer sharper terms again.

The commercial property loans hub covers the full category, from office through to industrial and retail.

Can I buy a vacant office or one with a short lease?

Yes, but a vacant or short-leased office changes how the loan is structured, because there is less in-place income for the lender to underwrite against. The three approaches I see most often:

  • An owner-occupier business case, where you move your own business into the office and serviceability comes from your trading position.
  • A leasing strategy with credible tenant interest documented, so the lender can see a path to income.
  • A stronger borrower position, a larger deposit and lower LVR, to offset the lack of a sitting tenant.

Big 4 and major banks have limited appetite for a vacant office without one of those structures. Non-bank lenders and private capital are more flexible, and price for the additional risk. If you are weighing a vacant purchase, book a free consultation and we can talk through the deal.

Can I buy an office through my SMSF?

Yes, you can buy an office through a self-managed super fund, commonly to lease it back to your own business at market rent. An office is business real property, which is the category the ATO allows an SMSF to acquire and lease to a related party, provided the arrangement is at arm's length.

The office deal itself looks a little different inside super. The LVR is more conservative, typically around 65%, and the loan is held under a limited recourse borrowing arrangement. Because the compliance rules are specific, our SMSF commercial property loans page covers the full pathway, and the ATO ruling SMSFR 2009/1 sets out the business real property definition in detail.

Loan structure and LVR

What LVR can I expect on a commercial office loan?

Office LVRs typically sit between 60% and 80%, depending on who is buying and how the office is leased. Within that range, the position varies by buyer type:

  • Owner-occupier, prime or A-grade office: up to 80%
  • Owner-occupier, first-time buyer: up to 75%
  • Investor, long lease to a quality tenant: up to 75%
  • Investor, mid-tier or short-lease tenant: around 65% to 70%
  • Strata office suite: around 70%
  • SMSF purchase: around 65%

Owner-occupiers consistently access a higher LVR than investors on an equivalent office, because the lender is leaning on your business rather than a third-party tenant. The factors that move LVR most are tenant covenant and WALE for investors, and serviceability for owner-occupiers. Our commercial property loan interest rates page covers current pricing across categories.

How does buying as an owner-occupier compare to buying as an investor?

The difference comes down to what the lender assesses. As an owner-occupier, the loan leans on your business's trading position and serviceability, and you typically access the sharpest LVRs and pricing because the office is occupied by a business the lender can assess directly.

As an investor, the loan leans on the tenant covenant, the lease and the WALE. A long lease to a strong tenant can secure terms close to owner-occupier levels, while a short lease or weaker covenant sits a step below. If you are deciding whether to buy your premises or keep leasing, our buy vs rent calculator compares the long-term economics.

Are interest-only periods available on office loans?

Yes. Big 4 and major banks typically cap interest-only at three years, non-bank lenders often extend to five years, and private capital can sometimes structure full-term interest-only. Buyers usually choose interest-only to protect cashflow in the early ownership period, particularly through a fit-out or a gap between settlement and a tenant moving in. The trade-off is a higher overall interest cost across the life of the loan.

Property and lease considerations

How does the lease and WALE affect my office loan?

On an investment office, the lease profile is the single biggest lever on your loan, often moving the LVR more than your balance sheet does. Lenders weigh the WALE, the weighted average lease expiry, against the tenant covenant: a long lease to a government or blue-chip tenant unlocks the best terms, while a short remaining term or an early break clause can quietly cut what they will advance. This is why I get the lease reviewed before a client makes an offer, not after.

Do building grade and parking really affect the loan?

Yes, both feed directly into the valuation and the lender's appetite. The factors that move an office most are:

  • Building grade: prime and A-grade offices in established locations attract the sharpest terms.
  • Parking ratio: more than four spaces per 100 sqm of net lettable area presents well, as tenants increasingly prioritise staff parking.
  • Floorplate and fit-out: efficient, flexible floor space re-lets more easily, while a heavily specialised fit-out can narrow the buyer pool.

Specialised offices are sometimes assessed differently again. A fitted consulting or medical suite, for instance, has its own specialist lender pool. For wider context on how office markets are moving across the capital cities, our commercial property market insights cover the trends.

Process and timing

How long does commercial office finance take?

Office finance timeframes vary by lender: Big 4 and major banks usually take 6 to 10 weeks, non-bank lenders 4 to 6 weeks, and private capital 1 to 3 weeks. The biggest accelerators are clean documentation, a clear lease and tenancy schedule ready at submission, and matching the deal to a lender I already know is writing your type of office.

The most common delays come from lease and WALE questions surfacing late, body corporate documentation gaps on strata suites, and valuation lead times. If you are refinancing an office you already own rather than buying, that runs on its own timeline. To get moving, book a free consultation and we can map the likely path for your deal.
