Step 1 – Know Your Rights
The Residential Tenancies Act 1995 outlines the rights you have as a tenant when renting in SA.
- Landlords/rental providers must provide tenants with at least 60 days written notice to the tenant before a rent increase
- Rent can only be increased in the following scenarios;
- Fixed agreements
- If there is a clause in your rental agreement stating the rent will increase, it needs to say how this will be worked out (or a specified amount)
- increase cannot start until 12-months after the agreement or the last increase
- with an offer for a lease extension (provided it has been 12 months since the last increase or the start of the agreement).
- Periodic agreements
- increase cannot start until 12-months after the agreement or the last increase
- with an offer for a lease extension (provided it has been 12 months since the last increase or the start of the agreement).
- Fixed agreements
- There is no limit on the increase, however, if you believe the rent is excessive/unreasonable you can apply to SACAT and challenge the increase.
Step 2 – Steps to finding out if your rental increase is fair
- Log in to your www.rentrabbit.com.au account
- Select “Dashboard” from your drop-down menu
- Select the “Suburb Trends” option from your taskbar
- Type in your Suburb name (in this example we have used Ridgehaven)
- Ascertain your suburbs % increase


Step 3 – Calculate your suburb’s median % rent increase
- Using Ridgehaven we will calculate its median % rent increase
- In this example, in the last 12 months, the median house rent when from $380 to $410.
- $410 divided by $380 = 1.0789
- (1.0789 minus 1) times by 100 = 7.89%
- Therefore, the median house rent in Ridgehaven went up 7.89%
- In this example, in the last 12 months, the median house rent when from $380 to $410.
- Now let’s calculate your property’s value (if you were based in Ridgehaven, remember to always use your suburb in part 1).
- Your landlord is requesting an increase in rent from $400 p/w to $460 p/w.
- $460 / $400 = 15% increase (therefore your landlord’s increase is over 7% more than the current market data suggests)
- What the suburb data is showing is that for a $400 p/w property the increase should be:
- $400 * 0.079 = $31.60 increase
- $400 + $31.60 = $431.60
- We can see from this example the increase should be roughly from $400 p/w to $430 p/w
Step 4 – How to reply to your landlord/rental provider to propose a revised increase
Here is a draft response
“Hi {insert name of landlord or agent},
I’ve recently received notification of a proposed increase in rent from {$X} to {$X} per week. The suggested price increase is too high, the market in our area over the last 12 months suggests the median rate has in fact {dropped or risen slightly} to {X %}.
It would be great if we could discuss terms and find something we are both happy with. I enjoy living here and I am a good tenant, having kept the property in excellent condition.
To help with the landlord’s decision, below is recent market activity demonstrating a {house/unit} median increase in {Insert your suburb name} of {X%} from 12 months ago. We’d like to negotiate a 12-month fixed lease for {$X} considering the market rents for comparable properties.
{Insert median house/unit data from your suburb search}
In addition, it’s likely if we were to relocate that the owner would perhaps be up for a re-letting fee ($800-$1500), potential loss of rent if it was vacant and unknown quality of tenants.
Thank you,“
