How to Use AI to Advertise Your Granny Flat Rental

Posted 19th September, 2025

Artificial Intelligence (AI) is all the rage right now, and granny flat owners can make the most of it for free to help get their rental leased. Check out these tools and techniques you can use to make your GrannyFlat Rental Listing clear, professional and desirable to tenants.

Why use AI:

• Save yourself a bit of the time you’d take to research similar listings and write an engaging property description
• See what wording and features are popular to advertise (e.g. without prompting, ChatGPT added ‘Pet Friendly’ when asked to generate a property description for a granny flat in Central Coast, showing that this is a desirable offering for tenants in the area.)
• Let AI come up with some extra advertising ideas that you might not think of
• Be reminded of some property features that you may be used to, and would otherwise forget to advertise
• Have your listing formally written

Get a head start with Google AI Overview:

• Search “how much does it cost to rent a _ bedroom granny flat in _” to get a quick summary of the rent per week of similar listings, and price your granny flat competitively within the price range provided.

• To get some inspiration about how to advertise the location of your granny flat, just search in Google “What’s it like living in _?”.
• Use the generated result to add a small paragraph about the perks of your location to the start or end of your property description.
• Always be sure to click the little link icon next to each section and check the source of the information.

Using AI writers to generate a rental property description

• Note: Always read the result and customise the listing to make sure all the information matches your own property
• Start with a simple prompt like “write me a property description for a _ bedroom granny flat in _”
• After your simple prompt, add a list of any inclusions/features that your property has that you’d like advertised:
• Floor boards
• Carpeted bedrooms
• Built ins
• Ensuit
• New full kitchen
• Internal laundry
• Furnished
• Wi-fi Included
• Garden Maintenance
• Close to beach
• Walk to shops
• Air-conditioning
• Fire place
• Pet friendly
• Fenced yard
• Deck
• Views (e.g. ocean, city, forest, mountain or river views)
• Play around with adjusting the listing by adding more follow up prompts, like “make it more succinct”
• You could instruct AI to use a friendly tone, or a more professional tone, depending on the type of tenant you’d like to attract
• Other key words you can add to your prompt to influence the result include:
• Formal
• Informal
• Direct
• Succinct
• Exciting
• Informative
• Relaxed
