Landlords comparing agents almost always start with the management fee. It's the visible number, so it gets the attention. But the biggest number in property management is one that never appears on a fee schedule: the rent you don't collect while the property sits empty.
The arithmetic nobody runs
Take a property renting at $550 a week. Every week it sits vacant costs you $550 — gone permanently, not deferred. Now compare that to fees: the difference between a 6.6% agency and an 8.8% agency on that same property is about $12 a week. In other words, one extra week of vacancy costs the same as an entire year of paying a higher management fee. Landlords will switch agencies over half a percent, then wait three weeks longer than necessary for a tenant without blinking.
Where vacancy actually comes from
In a market as tight as Adelaide's, extended vacancy is rarely about demand. It usually comes from process:
- Slow turnaround between tenancies — the outgoing inspection, maintenance and re-listing happening in sequence instead of in parallel. A well-run changeover starts marketing before the old tenant has left.
- Overpricing by a little — $20 a week above market doesn't make applicants negotiate, it makes them not apply. Three extra vacant weeks to chase $20 a week takes over a year to claw back.
- Slow application processing — good tenants apply for several properties at once and take the first approval. If references take a week, the best applicant has already signed somewhere else.
- Waiting for the portals to work — if an agency's only marketing is the listing itself, every let starts from a standing start.
What shortens it
The levers are unglamorous but they compound: pricing the property to the evidence rather than hope, photographing and listing before the keys are back, processing applications within a day or two, and keeping a database of prospective tenants who've asked to hear about rentals before they're advertised — which is exactly why we run a rental alerts list, and why our listings often have registered interest before the first open.
How to read an agency through this lens
When you're comparing agents, ask about their last few lets: how many days from listing to lease signed? How do they handle the changeover period? What happens to applications received on a Saturday? The answers tell you more about what a management will really cost you than the percentage does. Then weigh the fee — ours are published, so you can do that part without ringing anyone.
