Personalised guidance for every role in this market.
🧑💼 Buyer Strategy
- Prioritize homes with 'coastal-grade' fixtures (stainless steel, treated timber).
- Check the school catchment boundaries carefully; they are strictly enforced.
- Look for properties with side-access for boats or caravans, as this is highly valued here.
- Inspect the roof and gutters for salt-related corrosion.
- Visit the property on a windy day to understand the impact of the 'Fremantle Doctor' breeze.
❓ Questions to Ask the Agent
- Has the property been treated for coastal corrosion in the last 5 years?
- Is the reticulation connected to a bore or mains water?
- What are the specific school catchment zones for this street address?
- Are there any known issues with the local dune stability nearby?
- What is the typical electricity cost for this home during summer?
- Has the roof been inspected for salt-spray damage to the pointing or tiles?
- What are the council rates and are there any specific coastal levies?
🏷️ Seller Strategy
- Highlight energy-efficient features like solar panels to offset high cooling costs.
- Ensure the garden is professionally landscaped; 'curb appeal' is vital in this suburb.
- Showcase any outdoor entertaining areas as 'lifestyle extensions'.
- Address any visible rust or salt damage before listing to avoid low-ball offers.
- Target marketing towards families in the northern suburbs looking for better value coastal living.
📣 Positioning Tips
Position the property as a 'turn-key lifestyle upgrade' for growing families. Emphasize the proximity to Comet Bay College and the beach.
💼 Investment Case
High-income family rental market with low vacancy.

- Look for properties within 1km of the Secret Harbour Square shopping centre.
🔑 Renter Tips

High electricity bills in summer and limited late-night public transport.
🏢 Landlord Strategy

Ensure all RCDs and smoke alarms are coastal-rated to prevent salt-air failure.
