Medical Property Leases: Gross, Net and Cost Allocation

Few decisions shape the long-term economics of a medical tenancy quite as profoundly as the lease structure agreed at the outset. Whether you are a GP establishing a new clinic, a specialist seeking rooms in a purpose-built centre, or an investor acquiring a healthcare asset, the distinction between gross and net lease arrangements carries real financial consequence. Getting this right demands a working understanding of how costs are allocated, who carries the risk of rising outgoings, and what the lease document actually commits each party to.

A gross lease, at its simplest, is one where the landlord accepts responsibility for most or all of the property's operating costs. The tenant pays a single agreed rent and the landlord absorbs outgoings such as council rates, building insurance, and routine maintenance. For medical tenants, this structure offers predictability. A GP principal or practice manager running a busy clinic has limited appetite for fluctuating annual bills tied to council rate revisions or insurance premium movements. The gross model insulates them from that volatility, which is why it remains common in smaller suburban medical suites and some purpose-built GP-anchor centres.

Net leases shift the equation. Under a net arrangement, the tenant contributes directly to some or all outgoings beyond base rent. A single-net lease might see the tenant paying council rates while the landlord retains insurance. A triple-net structure, sometimes called NNN, passes council rates, building insurance, and maintenance costs to the tenant. This model is well established across specialist medical centres and larger healthcare precincts, particularly where institutional investors hold the asset and require a clean, predictable net income stream. For practices setting up or expanding, the total occupancy cost under a net lease can differ substantially from the headline rent figure, and failing to model that gap at the negotiation stage is a costly mistake.

Common area maintenance charges, often referred to as CAM, deserve particular scrutiny in shared medical buildings. These charges cover the upkeep of lobbies, car parks, lifts, shared corridors, and amenity facilities. In a mixed-tenancy building housing a GP clinic, a pathology collection point, and allied health suites, CAM is typically apportioned by net lettable area. The mathematics can appear straightforward, but the devil sits in the definitions. Some leases cap annual CAM increases; others do not. Tenants should also examine whether management fees or administrative charges are buried within CAM schedules, a practice that inflates costs beyond the direct expense of maintaining shared spaces.

Land tax is a frequently misunderstood outgoing in Queensland medical property. The state levies land tax on owners whose holdings exceed the applicable threshold, and many commercial leases permit landlords to recover a proportionate share of this cost from tenants. Whether that recovery is permissible, and how it is calculated when a landlord holds multiple properties, is a matter that warrants specific legal advice. Business Queensland provides guidance on state tax obligations, and tenants should ensure any land tax recovery clause in their lease reflects only the liability attributable to the specific property rather than the landlord's broader portfolio.

Council rates and building insurance are outgoings that appear in most net and modified-gross leases across Queensland's medical property market. Council rates vary by local government area and property classification, and a medical centre in a higher-rated commercial zone will carry a meaningfully different annual charge than one sitting within a mixed-use or health precinct overlay. Building insurance premiums have risen sharply in recent years across Queensland, driven partly by climate-related underwriting adjustments. Tenants in net or semi-gross arrangements who absorb insurance costs should understand what the policy covers, whether public liability is separated from building cover, and how premium increases are passed through.

For investors, the lease structure chosen at the time of acquisition fundamentally shapes asset yield quality. A fully net lease occupied by an accredited, RACGP-compliant practice with a long tenure typically attracts tighter cap rates than a gross lease where the landlord shoulders rising outgoing costs. The structure of Australia's health system, with its strong primary care foundation and sustained demand for accessible clinic space, underpins the defensive character of healthcare property. That does not, however, mean lease structures can be treated casually. A well-drafted lease that clearly defines each party's obligations around outgoings is the document that holds an asset's income profile together through a full lease term and beyond.
