Office rents in Parramatta, North Sydney and the growth-corridor business parks keep moving. For professional services firms with stable headcount, buying a strata suite converts a decade of rent escalations into principal repayments on an asset you keep.

How it works

Strata office is one of the most mainstream commercial asset classes — well understood by valuers, financeable by most banks. Owner-occupier professional services firms (law, accounting, financial planning, consulting) are a lender-favourite because of recurring fee income.

The attributes that matter: strata plan quality, floor-plate size vs headcount, parking ratio, building amenity, lift access, air-con control, after-hours access. B-grade buildings in good suburbs often finance better than A-grade in weaker ones.

Many firms buy as owner-occupier for simplicity. Multi-partner firms often buy through a holding structure where the partners each own a share, and the operating entity leases at market rent.

What commercial lenders actually look at

Business financials

Two years of returns for the professional firm. Recurring-fee revenue (retainers, trail commission, repeat client work) strengthens the servicing picture.

Property fundamentals

Strata plan, floor size, parking ratio, building amenity, lift access. B-grade in a good suburb often beats A-grade in a weak one.

Owner-occupier structure

Direct ownership or holding entity (trust, partnership, SMSF) leasing to the operating firm at market rent.

Parking

Scarce in Sydney CBD and inner-ring suburbs. Dedicated bays add significant valuation uplift.

Ways to hold the property

Structure sits between you, your accountant and your lender — tax, asset protection and succession all matter. Four common patterns we see with Western Sydney owner-occupiers:

Personal name

Simplest to arrange. Interest can be deductible against rental income. Little asset protection from a trading-business perspective.

Company

Common for long-term holdings inside a corporate group. Flat company tax rate on rent; no CGT discount at the company level.

Trust (discretionary or unit)

Flexible for distributing rental income and separating property from trading-business risk. Lenders are comfortable with clean trust documentation.

SMSF — leased back at market rent

An SMSF can borrow (via a Limited Recourse Borrowing Arrangement) to buy premises that meet the ATO's "business real property" test and lease them to your business at arm's-length market rent. High-level only — a licensed SMSF specialist and your accountant must confirm your situation.

This is general information only, not financial, tax or legal advice. Confirm your situation with a licensed credit adviser and accountant.

Growing SaaS or technology businesses with stable headcount
Multi-partner firms consolidating partner equity into a property holding
Family businesses succession-planning for the next generation
Firms moving from co-working or sub-leased space to owned premises

Frequently asked questions

Owner-occupier 70-80% is typical for mainstream suburbs. Strong firms with recurring fee income can push the top end. Investment-office with a sitting tenant usually 65-75%.

A-grade pays more for building amenity; B-grade often prices better per m² and in secondary markets can out-perform A-grade in weaker suburbs. Match the asset to your client-facing requirements.

Yes — partnership or unit trust is common for multi-partner firms. Each partner holds units proportionate to their equity. The operating partnership leases at market rent.

Not required by lenders but adds value. Zero-parking strata in the CBD finances fine; a parking-light suite in a car-dependent suburb may value lower.

A strata inspection and sinking-fund review is standard at due diligence. Serious issues (unresolved litigation, major defects, insolvent OC) will concern valuers and lenders.

LRBA is possible if the premises qualifies as business real property leased to your operating entity. High-level only; SMSF specialist confirms.

20-25 years amortisation with 1-3 year interest-only is typical for office. Office is a well-understood asset class, so terms are competitive.
