Hidden Lease Costs in Medical Property: A Step-by-Step Guide
Outgoings, fit-out amortisation, make-good, rent-free periods and incentive clawbacks. Learn how to compare the true cost of any medical lease offer.

Most healthcare tenants focus on the face rent when evaluating a medical lease. That number is rarely the whole story. This guide walks through every cost category that routinely catches GP clinics, specialist centres and allied health practices off guard, then gives you a practical framework for comparing the genuine bottom-line cost across competing lease offers, so you can negotiate and sign with confidence.
1. Understand What Outgoings Actually Cover
Outgoings are the landlord's operating costs passed on to tenants, and in medical properties they can be substantial. Common line items include council rates, building insurance, property management fees, lift maintenance, fire system compliance, and shared area cleaning. Always request an outgoings schedule for the most recent financial year, then calculate outgoings as a percentage of your face rent. That ratio tells you immediately whether the deal is structured in your favour or the landlord's.
2. Scrutinise How Fit-Out Costs Are Amortised
When a landlord contributes to your fit-out, that contribution rarely comes without strings. Many medical leases amortise the landlord's capital spend across the lease term and embed it in a slightly elevated base rent. Alternatively, some landlords treat the contribution as a separate loan to be repaid if you exit early. Ask your agent or solicitor to identify whether fit-out dollars are baked into the rent calculation, and by how much, before you compare two lease offers side by side. Our article on Landlord Fit-Out Incentives: What to Expect in Brisbane unpacks this structure in detail.
3. Calculate the True Net Value of a Rent-Free Period
A six-month rent-free period sounds attractive, but the benefit evaporates quickly when the lease term is long and face rent is high. Divide the total gross benefit by the number of months in the full lease term to find the monthly rent-equivalent discount. Then compare that figure across multiple offers. A shorter rent-free period with a lower ongoing rent often delivers greater lifetime savings than a generous upfront holiday attached to an inflated base.
4. Model Incentive Clawback Clauses Before You Sign
Clawback provisions allow landlords to recover some or all of their incentive contribution if you vacate before the lease expires. These clauses are standard in commercial medical leases, yet many tenants only discover them during a make-good dispute. Ask for the clawback schedule in writing at heads of agreement stage. Check whether it operates on a straight-line or accelerated basis, because the difference in a worst-case early exit can be significant. The RACGP running a practice guidance is a useful reference when thinking about practice lifecycle planning alongside lease commitments.
5. Map Your Make-Good Exposure at Lease End
Make-good clauses require tenants to return premises to their original condition, which in a medical fitout can mean stripping out joinery, plumbing, specialist flooring and gas lines. That cost is rarely trivial. Get a quantity surveyor to estimate make-good liability before you commit to a lease, not after you have already invested in the fitout. Negotiating a cash settlement figure at the start, or securing a make-good waiver, can save a practice tens of thousands of dollars on exit. See our detailed Make-Good Obligations in Medical Leases: The Complete Guide for the full negotiation playbook.
6. Stress-Test Each Rent Review Mechanism
Not all rent review clauses are equal. Fixed percentage reviews, CPI-linked reviews and market reviews each produce a different cost trajectory over a five or ten-year term. Run a simple spreadsheet projection for each mechanism, using conservative, base and high assumptions. A lease with fixed annual increases of three percent may look more expensive in year one than a CPI-linked alternative, but in a high-inflation environment it can save a practice a material amount over the full term. Understanding the review structure is as important as the opening rent.
7. Account for Compliance and Fitout Costs Specific to Medical Use
Healthcare premises face fitout compliance obligations that standard commercial tenants do not. Infection control separation, accessible bathroom standards under the National Construction Code, adequate ventilation for treatment rooms and soundproofing between consult spaces all add cost that generic fitout estimates will miss. The RACGP practice standards set minimum physical environment requirements for GP clinics, and similar guidance applies across specialist and allied health settings. Factor these costs into your total occupancy model from the start, not as a late-stage surprise.
8. Build a True Net Cost Comparison Table
Once you have collected all the above data for each lease offer, build a single comparison table. Rows should capture face rent, estimated outgoings, annualised value of the rent-free period, estimated compliance fitout cost, annual make-good provision, clawback risk weighting and rent review projections across the full term. Total each column. The offer with the lowest face rent will frequently not be the cheapest option once all variables are included. This table becomes your core negotiation document and your benchmark for future lease renewals.
9. Get Independent Advice Before Heads of Agreement
The single most costly mistake healthcare tenants make is seeking legal or commercial advice after heads of agreement are signed rather than before. Once a heads of agreement is executed, your negotiating leverage shrinks considerably and some terms become difficult to reopen. Engage a healthcare-specialist property advisor and a commercial solicitor at the term sheet stage, not at the lease execution stage. The AIHW health expenditure data consistently shows healthcare occupancy as one of the largest fixed costs for primary care practices, which makes getting this decision right more important than almost any other operational choice a practice makes.
A medical lease is a multi-year financial commitment that extends well beyond the rent figure on the first page. Outgoings, fit-out amortisation, make-good obligations, incentive clawbacks, rent review mechanics and compliance costs all compound across the lease term in ways that are genuinely hard to see without a structured framework. The practitioners who negotiate the best outcomes are those who model total occupancy cost before they enter a lease, not those who react to problems after signing.
